I am confused about the intricacies of the interaction between jit.gl.render, jit.phys.world and jit.gl.node.

I would like to have two sets of rigid bodies (right now they are gridshapes). One set is visible in a texture captured by jit.gl.node and the other set is not, but I'd like both sets to interact in a jitter physics world as rigid bodies. How do the naming and routing schemes work to achieve this?

Also, how does one use jit.phys.multiple, jit.gl.multiple, jit.gl.gridshape and jit.phys.body to produce multiple 3D shapes with physics interactions?

The patch below is an excerpt from my working patch. Any advice would be amazing. Additionally...I am still working in Max6.

jit-phys-jit-gl-render-and-jit-gl-node

Jit.gl.multiple @targetname gridshape 1 @glparams position (repeat for 2)

To spawn shapes send a 3 plane matrix to inlet 1 of jit.gl.mulitple just use

Not behind the computer but thats a quick start.

Thats a lot of different questions.
Regarding nodes
Gridshape1 node1
Gridshape2 node2
Have 2 jit.gl.nodes
Jit.gl.node @name node1 (repeat node2)

Jit.gl.multiple @targetname gridshape 1 @glparams position (repeat for 2)
To spawn shapes send a 3 plane matrix to inlet 1 of jit.gl.mulitple just use
Jit.noise 3 float32 8 8 8

Thank you Andro! This is a great start. I have one more question that I am unsure about at the moment. I am using jit.gl.multiple and jit.phys.multiple to render 150 spheres. I'd like each of the spheres to rotate along their local Y axis. How can I acheive this effect? The best I have been able to come up with is using jit.gl.multiple with a mesh input and using jit.anim.drive to rotate the initial mesh. Is there a less convoluted way of achieving this?

Jit.gl.multiple @targetname gridshape1 @glparams position rotatexyz

So inlet 1 is 3 plane matrix for position say jit.matrix 3 float32 8 8

Plug the packed matrixes into the 2nd inlet

So inlet 1 is 3 plane matrix for position say jit.matrix 3 float32 8 8
Inlet 2 is for rotation.
make 3 1 plane matrixes like
Jit.matrix 1 float32 8 8
Plug the 2nd one into
Jit.op @op * @val 360
Plug those 3 matrixes into
Jit.pack 3
Plug the packed matrixes into the 2nd inlet


Jit.phys, jit.gl.render, and jit.gl.node
