Ok, like the previous thread you had, i would suggest you to study the basic tutorials(starting from number 31). It is not very clear, either, want you want to do: do you want to mix the shape of the model with some other video layers? do you want to use the movies as textures for your model?
Some basic things to try:
1-create a gl context by providing a name to your jit.gl.render and jit.window(all that is explained on the tutorial 31). You will need to apply the same context name to your model(tutorial 36).
2-If you want to use the model as a video layer, you will need to use the @capture attribute and a jit.gl.texture. You can use different slabs to process your image. Use as a final destination a jit.gl.videoplane(tutorial 42).
3-If you want to use the movies as texture, make use of a jit.gl.texture and be sure to enable the texture attribute on your jit,gl.model(tutorial 34)
