Structs

• Cache
  File-handle and memory cache for reading ptex files
• DataSize
  Query the size in bytes for each DataType.
• OneValue
  Return the value of “1.0” for the specified DataType (1.0 (float), 255.0 (8bit), …).
• Res
  Pixel resolution of a given texture. The resolution is stored in log form: ulog2 = log2(ures), vlog2 = log2(vres)). Note: negative ulog2 or vlog2 values are reserved for internal use.
• Texture
  Interface for reading data from a ptex file
• Writer
  Interface for writing data to a ptex file.
• f16
  A 16-bit floating point type implementing the IEEE 754-2008 standard binary16 a.k.a “half” format.

Enums

• Error
  The main Error type returns either error Messages or FileIO errors.

Type Aliases

• BorderMode
  How to handle mesh border when filtering.
• DataType
  Type of data stored in texture file.
• EdgeFilterMode
  How to handle transformation across edges when filtering.
• EdgeId
  Edge IDs used in adjacency data in the Ptex::FaceInfo struct. Edge ID usage for triangle meshes is TBD.
• FaceInfo
  Information about a face, as stored in the Ptex file header.
• MeshType
  Type of base mesh for which the textures are defined. A mesh can be triangle-based (with triangular textures) or quad-based (with rectangular textures). */
• MetaDataType
  Type of meta data entry.
