Abstract
One embodiment of the invention includes a method for extending an object-oriented programming language to include support for a shading language vector data type. The method generally includes defining a template class for a shading language vector, defining a template class for a swizzled vector, and partially specializing the vector template class for vectors of one, two, three, and four elements. The partial specialization includes a union of instances of the vector swizzle template, where each instance represents a desired vector swizzle. In addition to defining the vector and vector swizzle data types, the templates classes may overload operators provided by the object-oriented programming language to perform operations corresponding to operations of the operators in the shading language.
