Summary

The Sort SOP allows you to sort points and primitives in different ways. Sometimes the primitives are arranged in the desired order, but the point order is not. There are many possible combinations. To sort vertices, use the Primitive SOP.

Parameters - Point Page

Point Sort ptsort - - Sort the points in the input geometry, according to the following criteria:

  • No change none - No sorting is applied.
  • By vertex order vtxord - Order points in same order as vertices.
  • By x byx - Sort according to X position.
  • By y byy - Sort according to Y position.
  • By z byz - Sort according to Z position.
  • Reverse rev - Reverse the point order.
  • Random seed - Randomize point order using the specified seed without changing the point positions.
  • Shift shift - Shift points by the amount specified on the Offset parameter.
  • Proximity to Point prox - Sort points by their proximity to the specified point.
  • Along Vector vector - Sorts points along either a user or object-defined vector.
  • Distance to Object object - Sorts points based on distance to the object specified in the Vector Object parameter.
  • Closest Neighbour neighbour - Reorders points based on next closest. Slow nxn search.

Seed pointseed - The random seed when Point Sort is set to Random.

Offset pointoffset - Shift point order by the amount specified on the offset line.

Point pointprox- - The X, Y and Z coordinates to reference when sorting by Proximity to Point.

X pointproxx -


Y pointproxy -


Z pointproxz -

Vector Object pointobj - Sort points along a vector defined by the object's transformation values.

Vector pointdir- - Allows you to specify a unique vector along which points can be sorted.

Parameters - Primitive Page

Primitive Sort primsort - - Sort the primitives according to the following criteria:

  • No change none - No sorting is applied.
  • By x byx - Sort according to X position.
  • By y byy - Sort according to Y position.
  • By z byz - Sort according to Z position.
  • By Type bytype -
  • Reverse rev - Reverse primitive order.
  • Random seed - Randomize primitive order using the specified seed without changing the primitive positions.
  • Shift shift - Shift primitives by the amount the specified on the Offset parameter.
  • Proximity to Point prox - Sort primitives by their proximity to the specified point.
  • Along Vector vector - Sorts primitives along either a user or object-defined vector.
  • Distance to Object object - Sorts primitive based on distance to the object specified in the Vector Object parameter.

Seed primseed - Random seed when sorting by Random.

Offset primoffset - Shift primitive order by the amount specified on the offset line.

Point primprox- - The X, Y and Z coordinates to reference when sorting by Proximity to Point.

X primproxx -


Y primproxy -


Z primproxz -

Vector Object primobj - Sort primitives along a vector defined by the object's translation.

Vector primdir- - Allows you to specify a unique vector along which primitives can be sorted.

X primdirx -


Y primdiry -


Z primdirz -


Parameters - Particle Page

Particles are sorted on a per-particle system basis. That is if you have a SOP with 2 different particle system primitives, they are sorted independently of each other.

Particle Sort partsort - - Sort the primitives according to the following criteria:

  • No change none - No sorting is applied.
  • By x byx - Sort according to X position.
  • By y byy - Sort according to Y position.
  • By z byz - Sort according to Z position.
  • Reverse rev - Reverse particle order.
  • Shift shift - Shift particles by the amount the specified on the Offset parameter.
  • Proximity to Point prox - Sort particle by their proximity to the specified point.
  • Along Vector vector - Sorts particles along either a user or object-defined vector.
  • Distance to Object object - Sorts particles based on distance to the object specified in the Vector Object parameter.

Reverse Results partreverse - Reverses the result from the Particle Sort as defined above.

Offset partoffset - Shift particle order by the amount specified on the offset line.

Point partprox- - The X, Y and Z coordinates to reference when sorting by Proximity to Point.

X partproxx -


Y partproxy -


Z partproxz -

Vector Object partobj - Sort particles along a vector defined by the object's translation.

Vector partdir- - Allows you to specify a unique vector along which particles can be sorted.

An Operator Family that reads, creates and modifies 3D polygons, curves, NURBS surfaces, spheres, meatballs and other 3D surface data.

Each SOP has a list of Points. Each point has an XYZ 3D position value plus other optional attributes. Each polygon Primitive is defined by a vertex list, which is list of point numbers.

The component types that are used to render 3D scenes: Geometry Component contain the 3D shapes to render, plus Camera, Light, Ambient Light, Null, Bone, Handle and other component types.

A surface type in SOPs including polygon, curve (NURBS and Bezier), patch (NURBS and Bezier) and other shapes like sphere, tube, and metaball. Points and Primitives are part of the Geometry Detail, which is a part of a SOP.
