Variations that generate meshes, three dimensional shapes made from connected triangles. These are all blur variations that ignore their inputs. They are most useful for solid renders, though they work for normal flames as well.
The mesh variations can perform subdivision surface smoothing. This can be helpful for some meshes to create a smoother surface. But it deforms meshes that aren’t designed to be smoothed. For example, smoothing an icosahedron will make it a sphere. This is done by first subdividing each triangle into four triangles, then performing Taubin smoothing on each triangle. This process is repeated the number of times specified by subdiv_level (set it to 0 to disable smoothing).
For each subdivision level, each triangle in the mesh is subdivided into four triangles and Taubin smoothing is done on each resulting triangle. Taubin smoothing is done with multiple passes, with two smoothing steps done on each pass. The first step uses the lambda parameter to smooth the mesh, but this also shrinks it. The second step uses the mu parameter (which should be a negative value) to counteract the shrinking.

obj_mesh_wf
Load a 3D mesh from an OBJ format file.
Type: 3D mesh
Author: Andreas Maschke (thargor6)
Date: 29 Nov 2016
The OBJ object file format was developed by Wavefront Technologies but is open and supported by many 3D graphics programs. It defines the XYZ position of each vertex and the faces that make each polygon in the mesh as a list of vertices. It can optionally define UV texture map coordinates for each face, used to map a 2D image to the mesh’s surface. These are used by the color and displacement map features. If the OBJ file does not include texture map coordinates, the color and displacement maps are ignored.
