haggi Posted July 27, 2011 Share Posted July 27, 2011 Hi, during the recreation of some shaders, e.g. a phong shader I simply built a small vop network to see which functions I have to call. Here I use the trace vex node. In this node I can find a function called vop_trace(...). To understand how it works, it would be extremly helpful to know the exact arguments and types of this node and what they mean. Unfortunatly a search for vop_trace didnt give me any results. It may be a stupid question, but where can I find the syntax an some more information about these functions? Quote Link to comment Share on other sites More sharing options...

bhaveshpandey Posted July 27, 2011 Share Posted July 27, 2011 (edited) is this about HDK?? I got it mixed with the vex functions Edited July 27, 2011 by bhaveshpandey Quote Link to comment Share on other sites More sharing options...
symek Posted July 27, 2011 Share Posted July 27, 2011 is this about HDK?? I got it mixed with the vex functions vop_trace is a plain vex wrapper around trace() vex function. The function itself is documentedin Help, so I've assumed what haggi is asking about is the wrapper. Quote Link to comment Share on other sites More sharing options...
haggi Posted July 27, 2011 Author Share Posted July 27, 2011 Ahhh, thanks a lot, this will help. And indeed I asked for the wrapper, but the trace itself is interesting as well. Quote Link to comment Share on other sites More sharing options...
