| Displacement in r | Displacement in θ | |
Defined on radial plane |
||
Example renderings of the four combinations of displacement in the $r$ versus $\theta$ directions, and placing the input texture on the radial plane versus on the Archimedean spiral. The rendered cut is tangential on the left side and near-radial on the right side. Figure is exaggerated and other features are simplified for exposition.
An orthographic camera views the wood from directly above. A point light orbits the center of the wood at a constant 60 degrees away from normal.
