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.
|
|
