i am new to jitter. trying to mix a gl-model with video (from a camera). mixing two videos is no problem. but how do i get the model - say the torus-example - into the correct form so that it mixes, or overlays the video. tried it with jit.matrix, alphablend, xfade, slab... is there an example out there ?

The trick is to get the video into GL land. connect the matrix you want to a jit.gl.videoplane and work with that- @blend_enable @blendmode, etc.

you need to transform the openGL rendering context to a texture, which is a 4 plane matrix, like the videos. once you have the rendering context as a texture/video, you mix it with xfade.

to get the wanted texture there are few ways. check jit.gl.asyncread help as an example.

check out my post over here about using "to_texture" on a jit.gl.render:

 - this example is for syphon, but it might help you.
