about

nx_camera_anim_gate.nx -- ★R4 of the Infinigen ladder: CAMERA RIG + ANIMATION + EXACT OPTICAL-FLOW GT (fills the animation GAP and CLOSES the R2 flow residual). A positionable/aimable camera (cam=[dx,dy,dz,yaw]) renders distinct frames = a trajectory; because our renderer KNOWS every pixel's 3D world point (ray*depth), reprojecting it through the next camera yields DENSE, EXACT optical flow -- the label real footage can't give and Infinigen's data is prized for. Two world renders (survives the box). T1 CAMERA RIG: two cam poses render substantially different frames (a real move, not a terrain reseed) T2 ★EXACT FLOW + PARALLAX: reproject A's world points through cam B -> dense flow; high coverage; COHERENT (neighbour flow similar); ★NEAR terrain flows MORE than FAR (parallax = the flow encodes 3D, the killer check) T3 WARP PROOF: A sampled at the flowed location matches real B far better than the no-flow baseline (the flow lands on the same surface) + panel knowledge/nx_flow_panel.png (frameA | flow-vis | warped | realB) license_tier: ORIGINAL expect_exit: 0
