Detailed Description

OpenGL utility class.

Member Function Documentation

static CL_GL1ProcAddress* CL_GL1::get_proc_address ( const CL_String8 function_name)
static

Get OpenGL extension specific function address.

static int CL_GL1::get_textureformat_bits ( CL_TextureFormat  format)
static

Returns the number of bits in a texture format.

static void CL_GL1::set_active ( CL_GraphicContext gc)
static

Sets the thread's OpenGL context to the one used by the graphic context.

static void CL_GL1::set_active ( const CL_GL1GraphicContextProvider *const  gc_provider)
static

Sets the thread's OpenGL context to the one used by the graphic context.

static bool CL_GL1::set_active ( )
static

Sets the thread's OpenGL context to the first valid allocated one.

If a valid OpenGL context is not found, then "no render context" is set.

Returns
true = Success. false = No OpenGL contexts could be found
static bool CL_GL1::to_opengl_pixelformat ( const CL_PixelBuffer pbuffer,
GLenum format,
GLenum type 
)
static

Get a OpenGL format out of a pixel format.

The function returns false if pixelformat color depth is not convertible to OpenGL pixel format, otherwise the format and type are returned with values in format and type.

static bool CL_GL1::to_opengl_pixelformat ( CL_TextureFormat  texture_format,
GLenum format,
GLenum type 
)
static

Get a OpenGL format out of a pixel format.

The function returns false if pixelformat color depth is not convertible to OpenGL pixel format, otherwise the format and type are returned with values in format and type.

static void CL_GL1::to_opengl_textureformat ( CL_TextureFormat  format,
GLint gl_internal_format,
GLenum gl_pixel_format 
)
static

To opengl textureformat.

Parameters
format= Texture Format
gl_internal_format= GLint
gl_pixel_format= GLenum
