Hey, I was told that, that I have to use VEX to use Houdini efficiently, so as I have no expierence at coding at all and I dont know where to start with it, I want to ask you guys if you have any good resources or learning paths. Thanks Nick
Hello dear community, I am having trouble scripting a second button on my hda. Both functions for the two buttons have been defined in the OnCreate callback in the scripts tab. While the first one is working fine, clicking the second one throws an error, saying the function or attribute defined in the parameter settings is not available. The callback-parameter for the first button has the value: kwargs["node"].hdaModule().OnCreateCurveButtonPressed() The second one has the parameter: kwargs["node"].hdaModule().OnCreateSectorsButtonPressed() And this is the error message that the console throws: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.607/houdini/python2.7libs\hou.py", line 23413, in __getattr__ def _SIDEEF_getattr__(*args): return _hou.HDAModule___getattr__(*args) AttributeError: 'module' object has no attribute 'OnCreateSectorsButtonPressed' Does anybody know whats causing this?
Smoothing geometry on the GPU using OpenCL. In VEX it has to be done in 2 steps where the same thing can be achieved in OpenCL in one step using barriers [khronos.org]. For a 822K polygon model, it's over 500 times faster than VEX on GTX 970 for 1000 iterations, and over 600 times faster for 10K iterations. Timings are recorded separately as there seems to be some overhead when running them one after another. Special thanks to SESI.
Link: CGWorkshop-- VEX in Houdini The course starts August 4th and runs for 8 weeks. I'm going to start out covering the basics of VEX, then we'll move on to some really fun projects. It's going be a good mix of visual effects related coding and really fun generative art. Check out the outline on the course website and if you have questions, ask away. I love teaching with Houdini as my blackboard, so I hope that comes across in the lessons. I want this course to kick ass; the world is full of boring programming classes and we don't need another! Happy Houdini'n -Shawn PS: XSI gals and guys, wanna learn VEX? I think I know a way... PS:PS: "Houdini'n" - is that a word yet. Can I say that?
