Member Function Documentation

static bool CL_GL1::from_opengl_pixelformat (  CLenum  format, CLenum  type, CL_PixelFormat &  pf )  [static]

Get a pixel format out of an OpenGL format. The function returns false if it can't convert format, otherwise the the formatare returned with values in pf.

static CL_GL1ProcAddress* CL_GL1::get_proc_address (  const CL_String8 &  function_name  )  [static]

Get OpenGL extension specific function address.

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 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 void CL_GL1::set_active (  CL_GraphicContext &  gc  )  [static]

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

static bool CL_GL1::to_opengl_pixelformat (  const CL_PixelFormat &  pf, CLenum &  format, CLenum &  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, CLint &  gl_internal_format, CLenum &  gl_pixel_format )  [static]

To opengl textureformat. Parameters: format  = Texture Format gl_internal_format  = CLint gl_pixel_format  = CLenum
