Classes

class  CameraSample
 
class  FilmBackXformOp
 FilmBack Xform Operation This class holds the data about a particular transform operation, but does not hold the actual data to calculate a 3x3 matrix. It holds the type of operation (Translate, Scale, Matrix), a hint about the type which can be interpreted by packages like Maya, and what particular parts of the operations can change over time.

Enumerations

enum  BasisType {
  kNoBasis = 0, kBezierBasis = 1, kBsplineBasis = 2, kCatmullromBasis = 3,

enum  CurveType { kCubic = 0, kLinear = 1, kVariableOrder = 2 }
 
enum  FaceSetExclusivity { kFaceSetNonExclusive, kFaceSetExclusive }
 Hint to indicate face membership is mutally exclusive. Some structures that group faces only allow a face to belong in one FaceSet, while other times a face is allowed to belong to any number of FaceSets. By default FaceSets aren't exclusive. More...
 
enum  MeshTopologyVariance {
  kConstantTopology = 0, kHomogenousTopology = 1, kHomogeneousTopology = 1, kHeterogenousTopology = 2,
  kHeterogeneousTopology = 2
}
 
enum  XformOperationType {
  kScaleOperation = 0, kTranslateOperation = 1, kRotateOperation = 2, kMatrixOperation = 3,
  kRotateXOperation = 4, kRotateYOperation = 5, kRotateZOperation = 6
}
 Enum that indicates the type of transformational operation. This enum is used when encoding and decoding the transform operation data. More...
 
enum  FilmBackXformOperationType { kScaleFilmBackOperation = 0, kTranslateFilmBackOperation = 1, kMatrixFilmBackOperation = 2 }
 Enum that indicates the type of 2d operation for cameras. This enum is used when encoding and decoding the 2d filmback data for cameras. More...
 
enum  GeometryScope {
  kConstantScope = 0, kUniformScope = 1, kVaryingScope = 2, kVertexScope = 3,
  kFacevaryingScope = 4, kUnknownScope = 127
}
 
enum  ObjectVisibility { kVisibilityDeferred = -1, kVisibilityHidden = 0, kVisibilityVisible = 1 }
 Values for the visibility property The top-compound object of AbcGeom Schema objects can include an optional visibility property. The value can express. More...
 
enum  MatrixHint { kMatrixHint = 0, kMayaShearHint = 1 }
 The Matrix identifier hint. Some 3d packages (like Maya) may have certain transformation operations that aren't supported in other packages. MatrixHint is meant to help with reading back into applications that natively support the type. More...
 
enum  RotateHint { kRotateHint = 0, kRotateOrientationHint = 1 }
 The Rotate identifier hint. Some 3d packages (like Maya) have multiple rotation operations that are mathmatically of the same type. RotateHint is meant to help disambiguate these similiar mathmatical types when reading back into applications that natively support the type. More...
 
enum  ScaleHint { kScaleHint = 0 }
 The Scale identifier hint. Some 3d packages (like Maya) have multiple transformation operations that are mathmatically of the same type. ScaleHint is meant to help disambiguate these similiar mathmatical types when reading back into applications that natively support that type. More...
 
enum  TranslateHint {
  kTranslateHint = 0, kScalePivotPointHint = 1, kScalePivotTranslationHint = 2, kRotatePivotPointHint = 3,
  kRotatePivotTranslationHint = 4
}
 The Translation identifier hint. Some 3d packages (like Maya) have multiple transformation operations that are mathmatically of the same type. TranslateHint is meant to help disambiguate these similiar mathmatical types when reading back into applications that natively support the type. More...

"GeometryScope" is the name we use for what is called Primitive Variable Class in the Renderman Interface. "Primitive Variable Class" is a bit non-descriptive in a geometry caching context, so we use the somewhat more meaningful (but still admittedly vague) "GeometryScope". Below is a table reproduced from PRMan Application Note #22 describing what each of these labels means for different types of geometry. From Prman Application Note #22 (and Prman Application Note #19) For every geometric prim, there is 1 value for "constant" geometry scope. To save space in my little table here, I'll leave out the "constant" column but just imagine it with a big happy column of '1's.

Values for the visibility property The top-compound object of AbcGeom Schema objects can include an optional visibility property. The value can express.

  • isDeferrred - the property is present but whether the object should be visible is determined by parents of the object.
  • isVisible - The object should be visible.
  • isHidden - The object is explicitly hidden.
Enumerator
kVisibilityDeferred 

When evaluating whether this object is visible we will walk up the hierarchy of objects looking for an object that has the visibility property and is either explcitly isHidden or is explicitly isVisible. If we reach the top of the archive, then the object is visible.

kVisibilityHidden 

The object has been explicitly made hidden.

kVisibilityVisible 

The object has been explicitly made visible.

Default regular rotation.

kRotateOrientationHint 

Rotation that goes along with the rotate pivot to help orient the local rotation space.
