Details

Surface normals may be used by many visualization tools to render smoother results. In this example we demonstrate:

• How to compute a surface gradient for a function plot
• How to unitize the gradient into a surface normal
• How to add the normal to the sample data stored by a MRPTree
• How to include normals in the cell complex
• How to increase sampling with a SDF function
• How to increase sampling near humps by testing derivatives
• How to balance a tree
• How to dump a cell complex into various file types
