Function Documentation

void _swrast_Clear	(	GLcontext *	ctx,
		GLbitfield	buffers
	)

Called via the device driver's ctx->Driver.Clear() function if the device driver can't clear one or more of the buffers itself.

Parameters:

	buffers	bitfield of BUFFER_BIT_* values indicating which renderbuffers are to be cleared.
	all	if GL_TRUE, clear whole buffer, else clear specified region.

static void clear_ci_buffer	(	GLcontext *	ctx,
		struct gl_renderbuffer *	rb
	)			[static]

Clear color index buffer without masking.

static void clear_ci_buffer_with_masking	(	GLcontext *	ctx,
		struct gl_renderbuffer *	rb
	)			[static]

Clear color index buffer with masking.

static void clear_color_buffers

(

GLcontext *

ctx

)

[static]

Clear the front/back/left/right/aux color buffers.

This function is usually only called if the device driver can't clear its own color buffers for some reason (such as with masking).

static void clear_rgba_buffer	(	GLcontext *	ctx,
		struct gl_renderbuffer *	rb
	)			[static]

Clear an rgba color buffer without channel masking.

static void clear_rgba_buffer_with_masking	(	GLcontext *	ctx,
		struct gl_renderbuffer *	rb
	)			[static]

Clear the color buffer when glColorMask is in effect.
