Does anyone have a patch that uses expressions with jit.gl.model?. I have searched forum and did not come up with a specific example . Read Andrew Benson's article but unclear of how to set things up to work with models.. Any help would be appreciated

I was just able to get my models working with jit.gl.multiple which seems the right track.. but would like to use expressions to directly manipulate geometry (vertex) of models so any direction would be great.

Take all this with a grain of salt as this isn't really my area of expertise, though I have been dabbling recently...

AFAIK, the way to do this is to get your models vertices outputting to a matrix. (jit.gl.model @matrixoutput 1). Then jit.expr could be applied to the matrix data.

As a quick way to check this out you could substitute jit.expr in [p add_noise] of the jit.gl.model help file (enabling matrixoutput) .

Also, there is an Appendix B: THe OpenGL Matrix format that will probably be of use to you for deeper investigations...
