Heightfield from Image
The Heightfield command creates a NURBS surface or mesh based on grayscale values of the colors in an image file.
The image's "height" is sampled at the specified number of control points along the u and v directions of the image.
Sets the scale of the height of the object.
Uses the image as a render texture for the created object.
Evaluates the color of the texture at each texture coordinate (u,v) and sets the vertex color to match.
Creates a mesh with vertex points at each of the sample locations.
Creates a surface with control points at each of the sample locations.
Creates a surface that passes through each sample location's height.
