Member Function Documentation

static void CL_OpenGL::check_error

(

)

[static]

Throw an exception if an OpenGL error was detected ( Using glGetError() ).

Remember to call glGetError() to clear any previous errors

static int CL_OpenGL::get_glsl_version_major

(

)

[inline, static]

Get the glsl version major number.

static int CL_OpenGL::get_glsl_version_minor

(

)

[inline, static]

Get the glsl version minor number.

static int CL_OpenGL::get_opengl_version_major

(

)

[inline, static]

Get the opengl version major number.

static int CL_OpenGL::get_opengl_version_minor

(

)

[inline, static]

Get the opengl version minor number.

static CL_ProcAddress* CL_OpenGL::get_proc_address

(

const CL_String8 &

function_name

)

[static]

Get OpenGL extension specific function address.

static int CL_OpenGL::get_textureformat_bits

(

CL_TextureFormat

format

)

[static]

Returns the number of bits in a texture format.

static bool CL_OpenGL::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_OpenGL::set_active

(

CL_GraphicContext &

gc

)

[static]

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

static void CL_OpenGL::set_active

(

const CL_OpenGLGraphicContextProvider *const

gc_provider

)

[static]

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

static bool CL_OpenGL::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_OpenGL::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
