about

nx_cube3d_spin_gate.nx -- ANIMATED 3D: the cube SPINS. Adds an integer sin/cos primitive (Bhaskara Q10) so the rotation is a function of TIME, then renders 6 successive Y-rotation angles as a FILMSTRIP (6 cubes side by side) -- the "video" axis for 3D scenes, all depth-sorted. Proves motion + reusable trig for every later animation. Composes nx_depth_tri. license_tier: ORIGINAL expect_exit: 0
