Detailed Description

A TypeDesc describes simple data types.

It frequently comes up (in my experience, with renderers and image handling programs) that you want a way to describe data that is passed through APIs through blind pointers. These are some simple classes that provide a simple type descriptor system. This is not meant to be comprehensive – for example, there is no provision for structs, unions, pointers, const, or 'nested' type definitions. Just simple integer and floating point, common aggregates such as 3-points, and reasonably-lengthed arrays thereof.

A type descriptor for MaterialX data types.

All types need to have a type descriptor registered in order for shader generators to know about the type. It can be used for type comparisons as well as getting more information about the type. Type descriptors for all standard library data types are defined by default and can be accessed from the Type namespace, e.g. Type::FLOAT. Custom struct types defined through typedef elements in a data library are loaded in and registered by calling the ShaderGenerator::registerTypeDefs method. The TypeSystem class, see below, is used to manage all type descriptions. It can be used to query the registered types.

Member Enumeration Documentation

enum TypeDesc::AGGREGATE

AGGREGATE describes whether our TypeDesc is a simple scalar of one of the BASETYPE's, or one of several simple aggregates.

Note that aggregates and arrays are different. A TypeDesc(FLOAT,3) is an array of three floats, a TypeDesc(FLOAT,VEC3) is a single 3-component vector comprised of floats, and TypeDesc(FLOAT,3,VEC3) is an array of 3 vectors, each of which is comprised of 3 floats.

Enumerator
SCALAR	A single scalar value (such as a raw `int` or `float` in C). This is the default.
VEC2	2 values representing a 2D vector.
VEC3	3 values representing a 3D vector.
VEC4	4 values representing a 4D vector.
MATRIX33	9 values representing a 3x3 matrix.
MATRIX44	16 values representing a 4x4 matrix.
