RE: set raycast direction with a Null?
Hi Raff Our university course is in South Africa. Streaming from anywhere except Digital Tutors (which is stil not great but manageable) is a disaster. We would really like the option to be able to buy the course and setup someway of allowing our students to stream it locally (as I wouldnt want to give them direct access to the file - that would just be asking for trouble) Do you know if there are any plans for something similar? I know we are not the only place of learnign that has issues with this.

I suggest anybody who has issues with the current system, but is genuinely interested in their products (not just mine, there are some very solid things out on CGS and more coming) gets in touch with them and sees what they can do.

Re: set raycast direction with a Null?
Hi Simon We currently have a MA 3D Animation course. 10 years ago when we started we also used Maya, but because of a lot of technical issues I eventually convinced them to switch to SI. It was a great decision as the students found it so much more intuitive and the quality of the student work went up. We also now have a 3rd year course which is more focused on traditional 2D animation that uses TV paint, and a 4th year course in compositing in AE. As far as I know we are the only place in SA where you can get a Postgraduate Degree in the field of Animation. We have also with the collaboration of Engineering started a games design degree, Its currently in its second year now and producing some really awesome stuff. Its also going to be a great feeder to the 3D MA as you will get folks who have a very good grounding in 3D at the beginning of the course.

You can get in touch with CGS to get confirmation, but I suspect they are streaming only. They had several workshops truly crippled by piracy, and since they moved to a new framework they actually did see a surge in sales and some workshops haven't appeared on the piratesphere at all, so I doubt they will revert that decision. I asked for mine to be downloadable actually, but as it's the same framework for everything it wasn't possible to make exception. The player is good though, it's a thin wrapper of Vimeo's, so is the hosting. Again, can't speak for them, but I'd be surprised if they were still downloadable (the originals were as I had control over the html pages wrapping them and I intentionally made the links solvable :) ).

Re: set raycast direction with a Null?
In principle I'm not fond of the idea of assuming everybody is a pirate and forcing these always online models on people, so no argument there. They did have a case for it it turns out, but (again in principle) I would have rather have opted out of it and risked losing a few sales, it wasn't possible though.

No way around not being able to see the video if you're offline though for now (again going by the assumption they are online only), and that -is- annoying, and has kept me away from a couple resources too. It might be possible to rip them with some videograbbing site or streamcatch software, it's just an mp4 managed h264 stream at the end of the day, or if you know personally any of my ex-alumni they might have the original downloadables around, but I wouldn't know, and it'd be that gray area where you have to decide for yourself whether it's ethical or not.

Re: set raycast direction with a Null?
It takes some getting used to. Peter's approach is far simpler and direct than mine. What I do is take a global axis (x,y or z based on the user's choice) and then rotate it to match the orientation of the null as given by the 3x3 orientation matrix (kine.global.ori). Where Peter accesses the 4x4 transformation matrix and pulls the desired axis, already rotated, directly. :D On Sun, Apr 7, 2013 at 12:21 PM, Sam sbowl...@cox.net wrote: Thanks Peter, that works great!

RE: set raycast direction with a Null?
You are most likely correct on that. I never did very well in math. I've probably learned a lot more about math since I've been using Softimage, than I ever did in school (My high school math teacher spent most of his time reading Isaac Asimov instead of teaching, so that may have something to do with it).

Re: set raycast direction with a Null?
I've never been at home learning maths from a book, but I found Khan Academy videos to be really handy. The site's all changed since I used it but it looks like all the vector/matrix stuff is in the Linear Algebra section and the physics video can be pretty handy for applying the maths as well.

Re: set raycast direction with a Null?
Mathematics for Computer Graphics, 2nd edition, by John Vince. End of Story. Best intro book on the subject you can get if you're starting from near zero. Pre-Calc for dummies is also pretty decent for a less CG-ish, more general easing into maths. It's meant for high-school going to college refreshing students memory or covering some gaps, but it's well laid out to get a quick once over of many things people were taught but never learnt, or simply don't remember.

Re: set raycast direction with a Null?
I think ICE has tremendous potential as a tool for learning math in a fun and immediately rewarding way, so much so that if I were a parent I'd be pushing hard for my (hypothetical) kids school to adopt it as a teaching tool. After seeing a lifetime of expensive and largely ineffective initiatives to try to get kids interested in math it's a little tragic that this tool with so much potential in that area is likely to go unrecognized. Though, saying that, ICE is one of the bast ways to learn the fundamental maths anyway.
