Generating and managing GL shapes
Help me conceptualise something. I’m trying to do the following:
A bang generates a 3D shape (a cube) which will animate for a while, time out and then die. Any number of 3D shapes can be generated independent of each other.
Not necessarily looking for code just tips on how this might be done.
i’m not sure why you think the jit.p.* objects won’t allow you to be flexible the the 3d shape. they simply output matrices, which can be position values for anything.
the conventional solution is to use jit.p with jit.gl.multiple, and the 3d shape can be anything that is compatible with jit.gl.multiple. you can enable/disable shapes using the scale parameter.
i wouldn’t worry about dynamically changing the number of voices. simply allocate the most you will ever need, and use the @enable attribute to turn shapes on and off.
here’s a little patch demonstrating the p objects with gl.multiple and gl.model:
