Surface Operators, also known as SOPs, are operators that can generate, import, modify and combine 3D surfaces (also called geometry). The surface types are polygons, curves, NURBS surfaces, metaballs and particles.
Sweet 16 SOPs
The following 16 SOPs are commonly used, we recommend familiarizing yourself with them.
|Circle||Circle, sphere, torus primitives.||Sphere, Torus|
|Grid||Grid, box, rectangle.||Box, Rectangle|
|Merge||Merge and delete.||Object Merge, Delete|
|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.
An Operator Family that reads, creates and modifies 3D polygons, curves, NURBS surfaces, spheres, meatballs and other 3D surface data.
An Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.
Exporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.
