Advanced Houdini VEX Training Course 11 years, 7 months
There are a few seats still open! Contact training at sidefx.com to register! Advanced Houdini VEX Training Course Saturday, July 7, 2007 - 9:45am - 5:30pm SESI will be hosting a one-day Houdini training course on VEX coding. This course is part 3 of a 3 part series of VEX classes. This advanced VEX coding class will focus on common challenges in production VEX coding, with a thorough look at the concepts involved as well as some advanced tips and techniques with source code. All three classes will have an emphasis on ASCII VEX code, although all concepts will be applicable to VOP net programming. http://www.sidefx.com/index.php?option=com_content&task=view&id=578&Itemi...
HDK : Pos using UV Attribute 11 years, 7 months
Hi All... I want to find position of a point on a surface using its uv attributes. "primuv" expression gives me the position, if the surface is NURBS, but it uses orignal NURB uv to calculate position and doesn't use texture uv atrribute that we modify. How to do that??? ----iamjaideep80 (Jaideep Khadilkar) TD, Sciclone Motion Graphics. --------------------------------- Take the Internet to Go: Yahoo!Go puts the Internet in your pocket: mail, news, photos & more.

motion blur for scrolling textures? 11 years, 7 months
Heya Darren, I'm working on practically the same issue as we speak. You mention that you are using chops to scroll the uv lookup. Can you not, in the same spirit export that same channel into the V attribute and use velocity blur? I don't have houdini in front of me at the moment but it sounds like it might might export velocities that would be primarily x-axis biased. if you flatten the 'ribbon' so it's x-axis aligned, then deform it into it's final place, would the v vector not deform along with it? Perhaps some old school cheating is in order. Export the V vector to N on flattened ribbon - and deform that... I'm probably misunderstand something though -- haven't reached the critical mass of coffee just yet... :) Gene ----- Original Message ---- From: Darran Edmundson <darran at edmstudio.com> To: sidefx-houdini-list at sidefx.com Sent: Monday, July 2, 2007 4:24:14 AM Subject: Re: [Sidefx-houdini-list] motion blur for scrolling textures?

I simplified things for the sake of posing the question ... perhaps too far ;-) Rather than a grid I actually have a complex twisted ribbon. From the camera perspective, you can see a huge swath in the foreground but also a number of coils at varying distance in the background.

Interviewing Candidates 11 years, 7 months
Hi, I'm wondering if anyone knows of any resources (or has any tips n' tricks) regarding hiring CG people. It seems very vague, the whole process, whether I'm being interviewed or am doing the interview. Basically, "What did you work on?", "Let's see your reel," and "When can you start?". There must be a more robust way of interviewing CG candidates, as right now it's largely based on trust and a reel, (which you have only done the shadow pass on the last tree on the left for). I found this article, but it's for programmers: http://tinyurl.com/yerw Sean -- Sean Lewkiw -- Rainmaker Digital 130 Shaftesbury Avenue London W1D 5EU -- +44 (0) 207.031.1138 (P) (Direct) +44 (0) 207.031.1136 (F) +44 (0) 795.606.7245 (M)

motion blur for scrolling textures? 11 years, 7 months
I have a stationary polygonal grid with horizontally scrolling UVs driven by a chop network. For a fixed camera, how does one go about achieving motion blur for the scrolling texture? I could imagine adding a velocity attribute to each point on the grid calculated as du/dt (evaluated at frame $FF) in the direction of the grid's local x vector. Would this be enough to generate motion blur of the texture (assuming, of course, that "velocity motion blur" is enabled in the mantra ROP)? Alternatively, perhaps I'd have more control over the final look by using the VelocityBlur COP. In which case, do I have to write my own surface shader to get the velocity attribute into one of the standard deep raster planes? As always, any advice is appreciated. Cheers, Darran. -- Darran Edmundson [darran at edmstudio.com] http://www.edmstudio.com
