SPDX-License-Identifier: Apache-2.0 DESCRIPTION =========== This header stores the OpenGL formats/types and two simple routines to derive the format/type from an internal format. These routines are useful to verify the data in a KTX container files. The OpenGL constants are generally useful to convert files like KTX and glTF to different graphics APIs. This header stores the OpenGL formats/types that are used as parameters to the following OpenGL functions: void glTexImage2D( GLenum target, GLint level, GLint internalFormat, GLsizei width, GLsizei height, GLint border, GLenum format, GLenum type, const GLvoid * data ); void glTexImage3D( GLenum target, GLint level, GLint internalFormat, GLsizei width, GLsizei height, GLsizei depth, GLint border, GLenum format, GLenum type, const GLvoid * data ); void glCompressedTexImage2D( GLenum target, GLint level, GLenum internalformat, GLsizei width, GLsizei height, GLint border, GLsizei imageSize, const GLvoid * data ); void glCompressedTexImage3D( GLenum target, GLint level, GLenum internalformat, GLsizei width, GLsizei height, GLsizei depth, GLint border, GLsizei imageSize, const GLvoid * data ); void glTexStorage2D( GLenum target, GLsizei levels, GLenum internalformat, GLsizei width, GLsizei height ); void glTexStorage3D( GLenum target, GLsizei levels, GLenum internalformat, GLsizei width, GLsizei height, GLsizei depth ); void glVertexAttribPointer( GLuint index, GLint size, GLenum type, GLboolean normalized, GLsizei stride, const GLvoid * pointer); IMPLEMENTATION ============== This file does not include OpenGL / OpenGL ES headers because: 1. Including OpenGL / OpenGL ES headers is platform dependent and may require a separate installation of an OpenGL SDK. 2. The OpenGL format/type constants are the same between extensions and core. 3. The OpenGL format/type constants are the same between OpenGL and OpenGL ES. 4. The OpenGL constants in this header are also used to derive Vulkan formats from the OpenGL formats/types stored in files like KTX and glTF. These file formats may use OpenGL formats/types that are not supported by the OpenGL implementation on the platform but are supported by the Vulkan implementation.
