RE: Difference between a force and a velocity ?

[Sandy Sutherland]

Ah - this is where you can tell the difference between a force and a velocity - 
as if you took your parrot with a volocity of [0,0,0] and gave it a force of 
your foot in it's butt > [Len100] then not only would you find 
out if the velocity of [0,0,0] meant it was dead, but you would also change the 
velocity to [100,0,0]

Re: Octane render

[Massimo Galluzzo]

So, i decided to pause Mental Ray (so damn frustrating) a bit and give iRay a 
go. with xsi 2013
I’m using a crappy nvidia geforce 570 with 1.3gb ram.

First render 8 minutes 
http://img844.imageshack.us/img844/1455/iray8min.jpg

Second render 19 minutes
http://img837.imageshack.us/img837/2981/iray19min.jpg

Third render with dof let it go for 26 minutes
http://img163.imageshack.us/img163/1103/26min2ksamples.jpg

Too bad we dont have this engine with a proper integration by AD, still cant 
believe they didnt implement it.
Not like people arent asking, maybe there are too few asking 

Anyway keep in mind my gfx card is quite bad, i might be able to test maxwell 
but i have to go to a friend studio since i dont have it.

Octane - 3hrs on a GTX580

  If so I will appreciate your comments and your point of view of Octane vs 
other renders you have used.


  And if you have used Arnold and Octane, which one you prefer.



  I have the Octane experience only from the videos and the demo.  It seems to 
me that it is like Maxwell but a lot faster.

RE: Difference between a force and a velocity ?

[Matt Lind]

Thanks for the validation, Brad.

Each instructor has their own methods because this was indeed the first example 
presented to me when I took physics years ago to make the distinction between 
speed and velocity.  The professor said straight up it would be the very first 
question on the exam (it was) and anybody who got the question wrong would fail 
the exam.  Nobody failed, to my knowledge.  It wasn't treated as a trick 
question, it was fundamental material.

He often reused examples across different topics so we could focus on the 
relevant new information and cut down the noise/relearning.  For example, the 
running track was reused (with slight modifications) as an introduction to 
'work' illustrating no work is performed if there is no displacement.  Since he 
already proved the theory with velocity, he didn't have to waste time 
re-explaining it for work.  While tough at first due to the abstract nature, I 
found his approach very refreshing as it allowed me to tackle tougher problems 
because I was exposed to the edge cases upfront and conditioned to not think of 
them as edge cases.  Edge cases are a product of our tools (math) to explain 
observed behavior.  The universe doesn't have a concept of edge case.

I think my professor chose this approach because he once mentioned students had 
problems progressing from newton's laws to quantum mechanics because as they 
entered more advanced levels, they tended to forget previously learned material 
still applied (or they didn't see the connection).  He conditioned students to 
think more about the problem rather than merely choose a formula and plug in 
numbers.  Often his toughest problems required the least amount of math to 
solve.  Some of his lectures could be really dry, as he was a dry guy himself, 
but he was probably the best physics professor I had of many.

Subject: Re: Difference between a force and a velocity ?

In the past 2 years, I attended college courses in Physics 101 and 201 at UT 
Dallas, as well as a Princeton Review course for the MCAT's which include heavy 
study in basic physics, especially about the definitions of fundamental units 
and concepts.

As it turns out, Matt is correct in that the example of displacement returning 
to origin will result in an average velocity of 0. Both my physics professor as 
well as the Princeton Review instructor took special care to mention this 
specific example more than once because it is a common trick question on the 
MCATs.

HOWEVER, and this is important. It is absolutely NOT the first and only example 
provided to explain the difference between velocity and speed. Nor did it come 
up during the first lecture about velocity. It was brought up long after we had 
repeatedly reviewed the concept, in an attempt to trip us up in order to 
demonstrate the exception.

Defining velocity and then using zero displacement to explain it is similar to 
introducing the letter 'p' and using the word 'pneumonia' as your very first 
example. If you have a problem with that, take it up with the lexicographers 
and wordsmiths?

Re: Octane render

[Leonard Koch]

This might not be 100% correct, but octane is I think simply optimized for
cuda, and NVidia optimizes all their cards at least partly for cuda.

Re: Octane render

[Steven Caron]

i think we all knew that comparing straight ray tracing speed, without
textures, displacement, subdivisions, and deformation motion blur... octane
was going to win. i mean thousands of processors that are great at doing
this type of work compared to ~12 more generalized processors, octane takes
advantage of the gpu and arnold doesn't... winner octane!

Re: Octane render

[Toonafish]

That was some good advice, thanks. I Reduced the diffuse samples to 4, 
diffuse rays to 3 but had to increase AA to 20 to get an acceptable 
amount of noise. The quality is about the same as before but the render 
time was reduced to 1h:33minutes. Also got rid of the sampling errors by 
clamping the sampling values.


But still much more fine noise overall then the Octane render, so I'm 
rendering one with a diffuse sample setting of 6.


https://dl.dropbox.com/u/4271217/Arnold_Classroom_AA20_DiffSamples-4_DiffRays-3_1h-33min.png

So far Octane is still the winner by a landslide. It's very quiet all of 
a sudden,  Maxwell, Vray anyone ?!

When using high AA samples (which is necessary for DOF or motion blur) 
I believe you can pretty much keep diffuse samples down to 1 or 2. You 
have to oversample a lot for the DOF, and this AA oversampling takes 
care of diffuse areas as well. Also, for this scene with the large 
windows you may get away with 2 or 3 bounces.

I'm rendering on a 6 core i7 3930 overclocked to 4 Ghz, so Arnold
is using 12 threads. With AA set lower the DOF is very noisy. But
you're right, maybe I could lower the diffuse samples a little.

This is one of the most intelligently absurd threads I've ever followed. :)

Re: Difference between a force and a velocity ?

[Bradley Gabe]

In the past 2 years, I attended college courses in Physics 101 and 201 at
UT Dallas, as well as a Princeton Review course for the MCAT's which
include heavy study in basic physics, especially about the definitions of
fundamental units and concepts.

As it turns out, Matt is correct in that the example of displacement
returning to origin will result in an average velocity of 0. Both my
physics professor as well as the Princeton Review instructor took special
care to mention this specific example more than once because it is a common
trick question on the MCATs.

HOWEVER, and this is important. It is absolutely NOT the first and only
example provided to explain the difference between velocity and speed. Nor
did it come up during the first lecture about velocity. It was brought up
long after we had repeatedly reviewed the concept, in an attempt to trip us
up in order to demonstrate the exception.

Defining velocity and then using zero displacement to explain it is similar
to introducing the letter 'p' and using the word 'pneumonia' as your very
first example. If you have a problem with that, take it up with the
lexicographers and wordsmiths?

Re: Difference between a force and a velocity ?

[Alok]

  
  
Totally agree with you Graham, and that
  is why is my earlier post I had clearly mentioned the distinction
  between average and instantaneous velocities. Moreover, in case of
  CG we never talk of average velocities, it is always
  instantaneous. So the example of average velocity was not
  relevant.
  

  On 14/02/2013 2:57 PM, Grahame Fuller wrote:


  The formula
[Inline image 1]
is valid for instaneous velocity and speed, but not average velocity and speed over an interval. I think that maybe that was the point of the example in the textbook.

Suppose we take 4 samples around the track. The average velocity is given by:

Vavg = AVG([ 6.66, 0], [0, 6.66], [-6.66, 0], [0, -6.66]) = ([ 6.66, 0] + [0, 6.66] + [-6.66, 0] + [0, -6.66])/4 = [0, 0]/4 = [0, 0]

However because speed has no direction (you cannot travel at -10km/h for example), the average speed is given by:

Savg = AVG (6.66, 6.66, 6.66, 6.66) = 6.66

Of course, this distinction is secondary to the more important distinction that velocity is a vector (length and direction) while speed is a scalar (magnitude only).

Sorry Matt but I think you're wrong, and you can consider me a mathematician (I have a Masters in Mathematics and a Bachelor in Physics, Chemistry and Mathematics).

Just taking a pure math approach now to set things right.

Velocity is a vector as we know with a magnitude as Speed and a direction.

So we can write:

[Inline image 1]

Where 's' is speed and 'v' is velocity and  [Inline image 2]  is the magnitude of the velocity.

Now in the above equation, we cannot have 's' as non-zero and 'v' as zero. Because if 's' is zero , 'v' will be zero and if 's' is non-zero so will be 'v'.

  * Verify and modify the alignment of the underlying rig nodes.
  * Verify and modify the collision geometry generated for the skull

Once you run the script, you may need to refresh your schematic and

In my experience with Face Robot I found the failure rate for 
auto-placement for facial landmarks to be very high. When all the 
nodes are hidden away, there's typically no way for you to tell until 
you've already spent time attempting to tune the performance without 
success.


The ability to see your landmark placement and often repair it before 
committing to the next step of the rigging process is extremely important!

Re: Octane render

[Christian Gotzinger]

When using high AA samples (which is necessary for DOF or motion blur) I
believe you can pretty much keep diffuse samples down to 1 or 2. You have
to oversample a lot for the DOF, and this AA oversampling takes care of
diffuse areas as well. Also, for this scene with the large windows you may
get away with 2 or 3 bounces.

Re: Octane render

[Toonafish]

scene file : https://dl.dropbox.com/u/4271217/Arnold_Classroom.rar

I'm rendering on a 6 core i7 3930 overclocked to 4 Ghz, so Arnold is 
using 12 threads. With AA set lower the DOF is very noisy. But you're 
right, maybe I could lower the diffuse samples a little.

Re: Octane render

[Christian Gotzinger]

Nice job there! I find that it doesn't match the Octane version in terms of
quality (not your fault):
a) It looks "floaty". That's just the problem with FG. You'd need insane
settings to get the flawless contact shadows of an unbiased renderer.
People like to combat that by using ambient occlusion, but usually the
result looks terrible to me, with dark corners everywhere.
b) Sampling noise of a biased renderer looks unnatural (see the reflection
on the table at the very left). Unbiased renderers otoh have very organic
noise, so often it's fine for there to be some.

I've used Octane many times for still shots and even for animations. Setup
times are short, render speed is good and the quality is great. Plenty of
features are still missing (such as motion blur), but once the Softimage
integration is ready it should become a real option for those who don't
like to use an external renderer.

Sorry Matt but I think you're wrong, and you can consider me a mathematician (I 
have a Masters in Mathematics and a Bachelor in Physics, Chemistry and 
Mathematics).

Just taking a pure math approach now to set things right.

Velocity is a vector as we know with a magnitude as Speed and a direction.

So we can write:

[cid:image001.gif@01CE0A9F.DCEA1810]

Where 's' is speed and 'v' is velocity and  
[cid:image002.gif@01CE0A9F.DCEA1810]  is the magnitude of the velocity.

Now in the above equation, we cannot have 's' as non-zero and 'v' as zero. 
Because if 's' is zero , 'v' will be zero and if 's' is non-zero so will be 'v'.

Here is a reference:

RE: Face Robot sculpting lips problem

[Manny Papamanos]

Hi, Nothing related in our db under this.

I checked with a Rock Falcon scene an this works well in 2013.

Some things to check:
In the schematic..
On the instance that appears when you hit "mouth", check that there is E,C,I in 
schematic associated with the node.
Check that there is E,V for the Face and that "facial soft tissue" operator is 
below the envelope op.
Perhaps there are  move components in the Modeling stack that interfere, delete 
them as a test.
Move the teeth back and forth, it may reveal something...
Send the scene to us, I can take a look or log something.

Hope it will not take as long as V-ray...

 Even that Maxwell for rendering uses it's own.  The workflow beween
Softimage and Maxwell is great with Fire. No fooling around or tweaking
things outside the software.  I hope that Next Limit will add the GPU
processing and perhaps it will be as fast as Octane.

 Nope, this is the best there is for SI at the moment as far as I know.

 Just watch the video in this thread and install the addon:
http://render.otoy.com/forum/viewtopic.php?f=29&t=24365

Make sure you also download and replace the dll that is mentioned later
on in the thread, and if your SI camera does not export correctly, try
changing the default units in the Octane prefs to meters.

But comparing both Arnold and Octane, all I can say is for most stuff
Arnold is still better suited and production proven, but Octane is a nice
addition. Some scenes I tested that took forever to render in Arnold render
in just a few minutes in Octane.

Can't wait for the interactive viewport plugin for Softimage though.

 If so I will appreciate your comments and your point of view of
Octane vs other renders you have used.

 And if you have used Arnold and Octane, which one you prefer.


 I have the Octane experience only from the videos and the demo.  It
seems to me that it is like Maxwell but a lot faster.

That would be swell. But I think we'd also might have to include
setup time then. I'm sure a with a lot of hours tweaking, testing
and some smart trickery you can get faster render speeds in a lot
of renderers, but the whole point with these unbiased renderers is
that you hardly have to send any time tweaking to get a realistic
looking render.

I think I spent about 30 minutes on the classroom scene adding and
adjusting materials and tweaking the lighting and camera before
hitting the render button. The only render optimization I did was
switch from direct lighting to path tracing.

Re: Difference between a force and a velocity ?

[Andreas Böinghoff]

Interesting thread - I never really thought about the technical aspects 
of that.


On 2/13/2013 12:37 PM, Leonard Koch wrote:

Apologies, there are a couple of number typos in the first one.

Here is the corrected version:

Velocity is the speed and direction at which an object moves.
Force is something with a strength and a direction that causes 
acceleration on the object and has an effect on its velocity.



Think about it like this:
You have some object, that is flying through space with a VELOCITY.

Maybe it is flying upwards, so the DIRECTION it is flying in would be 
[0, 1, 0].

And let's say that it is flying with a SPEED of 6 units per second.

Those are the two components our velocity is made of: In what 
direction is it flying and how fast is it flying there?


In ICE these two values are one vector [0, 6, 0] which you get by 
multiplying the SPEED (6) with the DIRECTION ([0, 1, 0]).
When you multiply a vector(a row of numbers) with a scalar(a single 
number) you simply multiply each element of the vector with the scalar.

[6*0, 6*1, 6*0] = [0, 6, 0] = the VELOCITY of the object

Now there is also the FORCE and this could be for example gravity or a 
wind blowing, just anything that will move the object.

What properties does a force have?
It pushes things in a certain DIRECTION.
It pushes things with a certain STRENGTH.

Let's say our force pushes to the left, so in Softimage it's DIRECTION 
would be [1, 0, 0].

And let's say that the STRENGTH of the forces push is 8.

Once again these two properties of the force are represented in one 
vector [8, 0, 0] which you get by multiplying the STRENGTH(8) with the 
DIRECTION ([1, 0, 0]).

[8*1, 8*0, 8*0] = [8, 0, 0] = the FORCE.


So now that we have a good idea of what a force and a velocity are 
let's see what happens when the force acts upon our little object.


The object is moving through space with the VELOCITY [0, 6, 0] and 
suddenly there is the FORCE [8, 0, 0] acting on it. Maybe an 
interstellar wind started blowing...
The FORCE is acting on the object and wants to push it in another 
direction/speed, which would give it a new VELOCITY since velocity = 
speed*direction.
But the object also has MASS, that is a measure of how resistant to 
changing velocity an object is. Let's say it has the MASS 4.


Now the force is still going to change the velocity of the object, but 
the effect will be reduced by the mass.
The formula for how it is going to be reduced by the mass, comes from 
the famous formula F=m*a ( force = mass * acceleration )

If we divide both sides of that equation by mass we get:
F/m = a ( force / mass = acceleration)
This tells us that we must divide our FORCE (F) by the MASS (m) to get 
the acceleration.

Force: [8, 0, 0]
Mass: 4
[8, 0, 0] / 4 = [8/4, 0/4, 0/4 = [2, 0, 0] = acceleration

Now all you have to do once you have computed your acceleration is to 
add it your velocity, to see what new velocity the force pushed it in.

So: PreForceVelocity + acceleration = PostForceVelocity
Velocity = [0, 6, 0]
Acceleration = [2, 0, 0]
[0, 6, 0] + [2, 0, 0] = [0+2, 6+0, 0+0] = [2, 6, 0] = PostForceVelocity


After our Object travelling with a mass of 4 and a velocity of [0, 6, 
0] interacted with a force of [8, 0, 0] its new velocity is [2, 6, 0]


A bit elaborate, but I hope it helps you gain some intuition.

Heya all,

I'm currently fishing around for interest and feedback on a
potential rigging (for animation) workshop.

The format and venue would be the same of my technical direction
one, CGSociety, Videos+Literature+Forums Feedback for eight weeks.
The costs, media access, infrastructure etc. are the usual they
provide these days.

I'm basically interested in knowing how many people would be
genuinely interested, and to get a rough idea of what level would
be the most popular.

Currently I have a couple curriculum sketched out, and am inclined
to do something that ranges from basics (familiarity with the
software the pre-req but not aimed to veteran character TDs) to
intermediate techniques for the animation end of things, so
deformation, other than the basics, and layered proceduralism
absent, but definitely touch on design, dev, modularity and
maths/tech fundamentals on building user facing rigs.

If interest seems to be skewed away from that though, I could
consider offsetting towards something of a more advanced level,
but I have a hunch it'd get a lot of lip service but less pull.

Timeframe would be a start some time between May and August,
depending on several factors.

Anyway, any expressions of interest, public or private, and
feedback would be sincerely appreciated.

Cheers,
Raff
