Re: [Bf-committers] An easy to use damped spline
I was confused by UI. I was always mistaken smooth curve weight with softbody goal weight. This W under X,Y,Z in Transform panel is not well scanned by the eye, expected here. There is a simply labelled Weight value above Radius value. It may think that it has same importance that radius, I didnot expected it to be softbody goal weight. It probably should not be visible or should be greyed out when there is not sofdody modifier on nurbs object. I will do a report for UIteam. 2015-01-03 11:44 GMT+01:00 Mikhail Rachinskiy : > Oh~ my bad. > > -- > Regards, > Mikhail Rachinskiy > ___ > Bf-committers mailing list > Bf-committers@blender.org > http://lists.blender.org/mailman/listinfo/bf-committers > ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers

Re: [Bf-committers] An easy to use damped spline
Hi Campbell, I think by “Nurbs Weights” Ronan ment this: http://wiki.blender.org/index.php/Doc:2.4/Manual/Modeling/Curves#Weight Which is not working since 2.5 But (for me) this is not really an issue since Blender's control point weight interpolation isn't nearly accurate anyway: http://www.blender.org/forum/viewtopic.php?p=3426&sid=811ac0150dae2688cd55939d8410423f I'd be happy if surfaces were completly removed from Blender (since they're by fact useless) and developer concentraited on getting curves (both Bezier and Nurbs) to a decent Maya/3dsMax level, and getting libs such as openNURBS to be able to import nurbs as meshes in Blender (like Modo does). How is the GSoC openNURBS integration project is going on by the way? Haven't heard about it lately. -- Regards, Mikhail Rachinskiy jewelcourses.com rachinskiy.com On Thu, Jan 1, 2015 at 5:02 PM, Campbell Barton wrote: > On Tue, Dec 30, 2014 at 12:41 AM, Ronan Ducluzeau > wrote: > > I just want to remind that currently nurbs weights are not working in > > master since 2.5. > > Tested, they work for nurbs curves & surfaces, but rather you use the > bug tracker if you found some case where they fail. > > > If someone is interested into improving Blender's nurbs; there is a lot > to > > do, anyways. > > > > 2014-12-29 1:47 GMT+01:00 Campbell Barton : > > > >> Heres a patch on Blender, > >> Removed the restriction of power-of-2 curve resolution. > >> https://developer.blender.org/P183 > >> > >> However I don't see any significant advantage this offers over > >> existing nurbs calculation method, even though its quite efficient, it > >> would need to be extended to support different orders (currently > >> hard-coded to order-4), cyclic curves, nurbs weights etc... > >> > >> Just posting the patch for reference if anyone likes to check on the > code. > >> > >> On Mon, Dec 29, 2014 at 8:03 AM, Campbell Barton > >> wrote: > >> > Its available here: > >> > http://download.blender.org/ftp/ton/dspline.pdf > >> > > >> > On Mon, Dec 29, 2014 at 7:28 AM, joe wrote: > >> >> Do you have a link to a paper? > >> >> On Sep 28, 2014 10:45 AM, "Fred" wrote: > >> >> > >> >>> Hi Campbell Barton, > >> >>> > >> >>> The amount of interpolation dots is 2^i, at the start of the demo > i = > >> >>> 4(16 dots) > >> >>> if you change i = 7 (the limit in the demo) than there are 128 > >> >>> interpolation dots. > >> >>> > >> >>> if I had set the limit in the demo to 10 then 1024 interpolation > dots > >> >>> was possible. > >> >>> > >> >>> If the spline is used in a 3 dimensional space, > >> >>> to compute an interpolated dot position takes: dim * 10 clock > cycles > >> = > >> >>> 30 clock cycles. > >> >>> I hope that it is fast enough. > >> >>> > >> >>> If you like to have a curve to the last plotted dot you have to put > two > >> >>> dots on each other at the end. > >> >>> You will see that it is symmetrical again. > >> >>> > >> >>> Please change the number to 7 in the demo and you see a curved line > in > >> >>> stead of dots. > >> >>> > >> >>> Much more is possible with this spline because the first, second and > >> >>> third derivative (parameterized ) of the curve > >> >>> is available in real time. > >> >>> > >> >>> I think that much more can be invented with this spline technique. > >> >>> I think that with some research tangent handles can be constructed > as > >> >>> well (if you like them?). > >> >>> What I did in the demo was the most simple way of using it. > >> >>> > >> >>> The essence is: a 3th degree curve in two (x,y) or more directions > is > >> >>> differentiated three times, and then again integrated 3 times. > >> >>> With floating point this is impossible , because it is not exact, > the > >> >>> curve runs away. > >> >>> But with integer computing it is exact and the spline exact a 3th > >> degree > >> >>> curve. > >> >>> > >> >>> It can also be used in ten or more directions, but more then 3 > >> >>> dimensions (x,y,z) is not practical. > >> >>> > >> >>> Fred. > >> >>> -- > >> >>> Fred schreef op 28-9-2014 om 18:30: > >> >>> > That is in the demo the case, because I programmed that the first > >> plot > >> >>> > point is actually two points. > >> >>> > the spline uses 4 points p0, p1, p2, p3 and the interpolation is > >> >>> > between p1 and p2. > >> >>> > > >> >>> > Campbell Barton schreef op 28-9-2014 om 17:42: > >> >>> >> Checked the test application, and not sure if this is intended > but a > >> >>> >> simple triangle has uneven distribution. > >> >>> >> > >> >>> >> see: http://www.graphicall.org/ftp/ideasman42/fred_curve.png > >> >>> >> > >> >>> >> On Mon, Sep 29, 2014 at 1:32 AM, Dan McGrath < > >> danmcgrath...@gmail.com> > >> >>> wrote: > >> >>> >>> Cool, got them.

Re: [Bf-committers] An easy to use damped spline
Heres a patch on Blender, Removed the restriction of power-of-2 curve resolution. https://developer.blender.org/P183 However I don't see any significant advantage this offers over existing nurbs calculation method, even though its quite efficient, it would need to be extended to support different orders (currently hard-coded to order-4), cyclic curves, nurbs weights etc... Just posting the patch for reference if anyone likes to check on the code.

Re: [Bf-committers] An easy to use damped spline
Heres an initial port of the PSpline.pas to C, (single C file, prints 2d curve to stdout). https://gitlab.com/ideasman42/fred-curve/blob/HEAD/pspline.c This is the n-dimensional variant, but for the test it only prints 2d values. My main concern with this method of calculating splines is it relies on integer values and bit-shifting. For Blender we would want it to calculate floating point values, I didnt investigate yet how well this method could be used with floats, would be interesting to check on next.

Re: [Bf-committers] An easy to use damped spline
Hi Campbell Barton,
The amount of interpolation dots is 2^i, at the start of the demo i =
4(16 dots)
if you change i = 7 (the limit in the demo) than there are 128
interpolation dots.
if I had set the limit in the demo to 10 then 1024 interpolation dots
was possible.
If the spline is used in a 3 dimensional space,
to compute an interpolated dot position takes: dim * 10 clock cycles =
30 clock cycles.
I hope that it is fast enough.
If you like to have a curve to the last plotted dot you have to put two
dots on each other at the end.
You will see that it is symmetrical again.
Please change the number to 7 in the demo and you see a curved line in
stead of dots.
Much more is possible with this spline because the first, second and
third derivative (parameterized ) of the curve
is available in real time.
I think that much more can be invented with this spline technique.
I think that with some research tangent handles can be constructed as
well (if you like them?).
What I did in the demo was the most simple way of using it.
The essence is: a 3th degree curve in two (x,y) or more directions is
differentiated three times, and then again integrated 3 times.
With floating point this is impossible , because it is not exact, the
curve runs away.
But with integer computing it is exact and the spline exact a 3th degree
curve.
It can also be used in ten or more directions, but more then 3
dimensions (x,y,z) is not practical.
Fred.

Re: [Bf-committers] An easy to use damped spline
That is in the demo the case, because I programmed that the first plot
point is actually two points.
the spline uses 4 points p0, p1, p2, p3 and the interpolation is
between p1 and p2.

Hi Dan,
Of course I can send you the project.
I have made two versions:
1) The spline is embedded in de demo:
2) The spline is an external .dll, de demo calls PSpline.dll
Which one do you prefer?
Fred.

Re: [Bf-committers] An easy to use damped spline
Could the project files be posted to a public URL?, Id like to be able
to look into this. but probably wont have time over the coming weeks.
The main source file compiles for me with minor edits on
Linux/FreePascal, but the demo relies on `Window` unit, which I assume
is provided by delphi/windows.

Re: [Bf-committers] An easy to use damped spline
Hey,
Just save out the delphi project and zip it up and email it to me direct
via email I guess (the mailing list wouldn't allow such a large
attachement). I was attempting to compile it on linux, so the compiled
dll's wouldn't be of much use to me unfortunately.
Thanks!

Re: [Bf-committers] An easy to use damped spline
Hi Dan,
Of course I can send you the project.
I have made two versions:
1) The spline is embedded in de demo:
2) The spline is an external .dll, de demo calls PSpline.dll
Which one do you prefer?
Fred.

So is/was Turbo Pascal (limited in features; eg: objects but no classes)

Anyway, just thought it was neat to see code in pascal (an elegant

[Bf-committers] An easy to use damped spline
I have developed an n-dimensional damped cubic spline. The algorithm is very short and it is extremely fast because it only uses shifting and addition.
