i'm sure this is simple, i'm not very experienced with jitter, i'm just confused as to the naming protocols of jit.gl.render/jit.gl.gridshape/jit.gl.videoplane and how to put two into one window if the names have to be the same to transfer the data.
You don't need to "name" the gridshapes, just have multiple jit.gl.gridshape objects that draw to the same jit.gl.render, which does need a name. So the gridshape objects draw into the named jit.gl.render context. Same for the videoplanes.
has within it
jit.gl.gridshape foo @shape sphere
jit.gl.gridshape foo @shape cylinder
each are unique objects in the single jit.gl.render scene.
I'm having this problem too. I have multiple shapes in the same named drawing context. When I scale, position or rotate them, the new positions do get drawn but the old ones don't get erased. It's not until I esc-fullscreen that the window displays (what I think) should be there. Here's what i mean...
