[jitter] Smoothing with sketch and gl_commands

Hello,

We have builded a patch witch load 3D objects (.obj) with a gl.model. Then we export the 3D matrix in jit.matrix using matrixoutput message and attempt to draw it with a gl.sketch using gl_command drawmatrix.

The 3D object appears, but it is not smoothed. So we have search a gl_command to smooth it...

Does anybody know the way to smooth our 3D object with a sketch drawing a jit.matrix?

Thanks for help

David

Using max 4.6.3, jitter 1.6.3 and 3DStudioMax 6 with plugin MaxToObj to build the 3D objects

Here is the patch, fellowed by the content of the Sphere.obj object.
