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.
