PRAGMATIC VEX 1 | GRADIENT ASCENT & DESCENT | 3D GEOMETRY

We have implemented gradient ascent and descent on planar geometry, much like a terrain where we used the gradient of the height.

For an arbitrary geometry, what can we use as the cost attribute? One thing we can use is depth.

Pragmatic VEX series is aimed to increase the technical capacity of the artists and TDs which will allow them to tackle more complex production shots with complete control and ease by acquiring a deeper technical understanding of how things work in Houdini at the lowest level with a strong applied focus on high-end feature film visual effects production.
