How to port our precious ICE stuff into houdini vex. Questions raised - how to create a custom parameter in VEX, just like we do in ICE, and why there are different results in math.
ok i got the answers from houdini experts - sanostol and Stefano Jannuzzo
1 Question is still open ))))
2 I think the problem is with the trigonometry nodes, since ICE treats the input as degrees, Houdini as radians.
You are mixing the two in your graphs, however if you want to get the same behavior in Houdini, you should plug a dagtorad node between your t and the sin and cos nodes.
scenes are here
fixed degree to radians
Andy58 made a great job with this stuff - very illustrative comparison and usage of the Point Wrangle node, channel expressions and vops
