See Category:SOPs for a full list of articles related to SOPs.
Surface Operators, also known as SOPs, are operators that can generate, import, modify and combine 3D surfaces (also called geometry). The surface types include 3D points, polygons, lines, particles, surfaces, spheres and meatballs. Particles and point clouds are now done primarily on the GPU using TOPs - see
particlesGpu in the palette and components in the
PointClouds folder of the palette.

|Copy||Copy or replicate.||Limit|
|Switch||Switch or blend multi-inputs.||Blend, Sequence Blend|
|Texture||Apply texture coordinated to points or vertices.||Material|
|Noise||Apply noise, twist and deform.||Twist, Deform|
|Transform||Transform point positions.||Script|
|DAT to||DAT table to SOP points.||Add|
|CHOP to||CHOP channel samples to SOP points.||Line|
|Trace||Trace a TOP image to polygons.||File In|
|Clip||Clip and carve.||Carve|
|Facet||Facet, subdivide, convert.||Subdivide, Convert|
|Sweep||Sweep, skin, rails.||Skin, Rails|
|Sort||Sort and reorder.|
- 3D geometry data, processed on CPU
- FBX Import: .fbx importer, File In SOP - recommend importing geometry from more mature modelers
- FBX Export: Right-click and select Save Geometry... In the File Browser that opens, change the file type to .fbx to create a FBX file of that geometry.
