Subdivider

generators/subdivider·v1.5.1

IN:1 OUT:1

SUMMARY

The Subdivider grows every triangle into an inset, extruded copy of itself with a skirt joining it to the original, repeated for the number of Subdivisions, turning any mesh into spikes, crystals or fractal relief. Extrude Strength sets the push along the face normal, Extrusion Falloff Exponent shrinks it at each level, Inset sets the size of each new face, and Minimum Area limits how far small triangles extrude.

With Do Falloff the Falloff Attribute scales the extrusion per point, so the relief blends across a falloff edge, and every input attribute passes through to the new geometry. Post Subdivide adds a smoothing Subdivide POP pass, and the normal controls recompute the output normals.

PARAMETERS

PAGESubdivider

Subdivisions	Subdivisions	Number of levels. Each splits a triangle into an extruded inset copy and a skirt, 7 times the triangles. Capped near 4 M triangles.
Extrude Strength	Extrudestrength	Sets the peak extrusion distance.
Extrusion Falloff Exponent	Extrusionfalloffexp	The extrusion is divided by this value at each level.
Inset	Inset	Sets the inset of the subdivided faces.
Minimum Area	Minarea	Sets the lower limit of the triangle area the extrusion divides by, so small triangles extrude further.
Do Falloff	Dofalloff	Weight the effect on each point by the Falloff Attribute.
Falloff Attribute	Falloffattr	The point attribute, 0 to 1, that weights the effect.
Post Subdivide	Postsubdivide	Run a Subdivide POP pass after the extrusion.
Depth	Iterations	Sets the number of subdivision iterations.
Crease Weight	Creaseweight	Determines how much sharp edges in the geometry should be preserved.
Simple Coefficients	Simplecoeffs	Enables simple coefficient computation when smoothing the interpolated points.
[+]Normals Action	Nml	Choose what to do regarding normals.
[+]Attribute Class	Attrclass	Makes the POP operate on point attributes, vertex attributes or primitive attributes where applicable.
[+]Normals Weighting	Nmlweighting	For point normals, choose how to weight the normals of the primitives the point is a part of.
[+]Compute Normals Technique	Compnmltech	Specify which technique to use to calculate point normals.
Max Number of Primitives per Point	Maxprimsperpoint	Used to allocate temporary storage, it should be set to the maximum number of primitives a point can be a part of in the input geometry.
Angle	Angle	For vertex normals, the threshold angle between faces above which the shared edge vertices don't share normals.

PAGECommon

Bypass	Bypass	Pass through the first input to the output unchanged.
Free Extra GPU Memory	Freeextragpumem	Free memory that has accumulated when output memory has grown and shrunk.
