DESCRIPTION
===========
This header implements several support routines to convert OpenGL formats/types
to Vulkan formats. These routines are particularly useful for loading file
formats that store OpenGL formats/types such as KTX and glTF.
The functions in this header file convert the format, internalFormat and type
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. File formats like KTX and glTF may use OpenGL formats and types that
are not supported by the OpenGL implementation on the platform but are
supported by the Vulkan implementation.
ENTRY POINTS
============
static inline VkFormat vkGetFormatFromOpenGLFormat( const GLenum format, const GLenum type );
static inline VkFormat vkGetFormatFromOpenGLType( const GLenum type, const GLuint numComponents, const GLboolean normalized );
static inline VkFormat vkGetFormatFromOpenGLInternalFormat( const GLenum internalFormat );
static inline void vkGetFormatSize( const VkFormat format, VkFormatSize * pFormatSize );
MODIFICATIONS for use in libktx
===============================
2019.5.30 Use common ktxFormatSize to return results. Mark Callow, Edgewise Consulting.
2019.6.12 Add mapping of PVRTC formats. "
