Jit.gl.plato matrixoutput.

Hello forums!

Should jit.gl.plato output its matrix the same way gl.gridshape and gl.nurbs does, with matrixoutput set to 1? I’m looking at the documentation and the forums and i can’t find information about it other than jit.gl.plato reference saying it should.

Another thing i’m having trouble with is when i capture a gl.plato with gl.node capture 1 attribute and send it to a videoplane, the lighting doesn’t follow like it does doing the same thing with gl.gridshape. I’m running Max 6.0.5 on MBP 7,1 OS X 10.6.8. Thank you!

hello.
you should set the gl.mesh @draw_mode attribute to triangles (instead of the default of tri_grid).

you may have better luck with the lighting if you send only the three position planes (eg, send the matrix to a jit.pack 1 @jump 3 before sending to the gl.mesh) and enabling @auto_normals on the gl.mesh.

please post a patch demonstrating the problem you are seeing with gl.node.

Hi!

Thanks for the new information. When i capture gl.gridshape to a jit.gl.node, if i have the lighting enabled, the lighting stays enabled when “projected” to a videoplane. This doesn’t happen with gl.plato though. The problem i have is that i cant see the edges of the “solids”. Thanks again for the new info about plato and mesh!

Hey

Now it’s working! I draw the solids with triangles on a mesh and capture that with my node. I wouldn’t necessary make a music video out of this patch yet but who knows :)

Edit: I guess i dont even need that jit.pack there..
