GLWrappers -- OpenGL Wrapper Library
The GLWrappers library contains classes and functions providing a C++ wrapper around the OpenGL API. This wrapper is an essential layer to support type-generic OpenGL programming in higher-level libraries. As a secondary function, the wrapper layer changes the design of the OpenGL API slightly to replace indexed enumerants such as light enums with proper indices, and to replace generic enumerants with function-specific enumerants to enable compile-time parameter checking.
Header Files
- GLScalarLimits.h
- GLScalarLimits is a templatized class describing traits and limits of integral OpenGL data types, to allow automatic conversion between integral types.
- GLScalarConverter.h
- GLScalarConverter is a templatized class supporting type conversions between integral OpenGL types that require a value transformation, for example the range transformation when converting a color with GLubyte components to a color with GLfloat components.
- GLColor.h
- GLColor is a class describing an RGB color value with optional opacity component. It is templatized by color component type and number of components, with implementations provided for all integral OpenGL types used to describe colors, and three and four components. The GLColor class provides convenient constructors with automatic conversions between component types, comparison operations, and componentwise access. Objects of class GLColor can be used as parameters for all OpenGL functions that expect color values.
- GLColorOperations.h
- GLColorOperations.h provides operations on objects of class GLColor. It supports the full range of RGB vector space operations, componentwise multiplication, and clamping of floating-point component colors.
- GLVector.h
- GLVector is a class describing three-dimensional homogeneous vectors, templatized by scalar type and number of actually stored vector components. Vector components not stored are treated as 0 for the second and third components, and as 1 for the fourth component. The GLVector class provides convenient constructors with automatic conversions between component types, comparison operations, and componentwise access. Objects of class GLVector can be used as parameters for all OpenGL functions that expect vector values, such as texture coordinates, normal vectors, and vertex positions.
- GLBox.h
- GLBox is a class representing three-dimensional axis-aligned rectangular boxes, templatized by the scalar type of the vector space and the number of actually stored vector components. Vector components not stored are treated as 0 for the second and third components, and as 1 for the fourth component.
