Define Documentation

#define COLOR_INDEX32   0x424243

Functions for allocating/managing renderbuffers.

Also, routines for reading/writing software-based renderbuffer data as ubytes, ushorts, uints, etc.

The 'alpha8' renderbuffer is interesting. It's used to add a software-based alpha channel to RGB renderbuffers. This is done by wrapping the RGB renderbuffer with the alpha renderbuffer. We can do this because of the OO-nature of renderbuffers.

Down the road we'll use this for run-time support of 8, 16 and 32-bit color channels. For example, Mesa may use 32-bit/float color channels internally (swrast) and use wrapper renderbuffers to convert 32-bit values down to 16 or 8-bit values for whatever kind of framebuffer we have.

		GLuint	blueBits,
		GLuint	alphaBits
	)

Add a software-based accumulation renderbuffer to the given framebuffer.

This is a helper routine for device drivers when creating a window system framebuffer (not a user-created render/framebuffer). Once this function is called, you can basically forget about this renderbuffer; core Mesa will handle all the buffer management and rendering!

void _mesa_add_renderbuffer	(	struct gl_framebuffer *	fb,
		GLuint	bufferName,
		struct gl_renderbuffer *	rb
	)

Attach a renderbuffer to a framebuffer.

void _mesa_add_soft_renderbuffers	(	struct gl_framebuffer *	fb,
		GLboolean	color,
		GLboolean	depth,
		GLboolean	stencil,
		GLboolean	accum,
		GLboolean	alpha,
		GLboolean	aux
	)

Create/attach software-based renderbuffers to the given framebuffer.

This is a helper routine for device drivers. Drivers can just as well call the individual _mesa_add_*_renderbuffer() routines directly.

GLboolean _mesa_add_stencil_renderbuffer	(	GLcontext *	ctx,
		struct gl_framebuffer *	fb,
		GLuint	stencilBits
	)

Add a software-based stencil renderbuffer to the given framebuffer.

void _mesa_copy_soft_alpha_renderbuffers	(	GLcontext *	ctx,
		struct gl_framebuffer *	fb
	)

For framebuffers that use a software alpha channel wrapper created by _mesa_add_alpha_renderbuffer or _mesa_add_soft_renderbuffers, copy the back buffer alpha channel into the front buffer alpha channel.

void _mesa_delete_renderbuffer

(

struct gl_renderbuffer *

rb

)

Delete a gl_framebuffer.

This is the default function for renderbuffer->Delete().

void _mesa_init_renderbuffer	(	struct gl_renderbuffer *	rb,
		GLuint	name
	)

Initialize the fields of a gl_renderbuffer to default values.

struct gl_renderbuffer* _mesa_new_depthstencil_renderbuffer	(	GLcontext *	ctx,
		GLuint	name
	)			[read]

Create a new combined depth/stencil renderbuffer for implementing the GL_EXT_packed_depth_stencil extension.

Returns:

new depth/stencil renderbuffer

struct gl_renderbuffer* _mesa_new_renderbuffer	(	GLcontext *	ctx,
		GLuint	name
	)			[read]

Allocate a new gl_renderbuffer object.

This can be used for user-created renderbuffers or window-system renderbuffers.

struct gl_renderbuffer* _mesa_new_soft_renderbuffer	(	GLcontext *	ctx,
		GLuint	name
	)			[read]

Allocate a software-based renderbuffer.

This is called via the ctx->Driver.NewRenderbuffer() function when the user creates a new renderbuffer. This would not be used for hardware-based renderbuffers.

void _mesa_reference_renderbuffer	(	struct gl_renderbuffer **	ptr,
		struct gl_renderbuffer *	rb
	)

Set *ptr to point to rb.

If *ptr points to another renderbuffer, dereference that buffer first. The new renderbuffer's refcount will be incremented. The old renderbuffer's refcount will be decremented.

void _mesa_remove_renderbuffer	(	struct gl_framebuffer *	fb,
		GLuint	bufferName
	)

Remove the named renderbuffer from the given framebuffer.

GLboolean _mesa_soft_renderbuffer_storage	(	GLcontext *	ctx,
		struct gl_renderbuffer *	rb,
		GLenum	internalFormat,
		GLuint	width,
		GLuint	height
	)

This is a software fallback for the gl_renderbuffer->AllocStorage function.

Device drivers will typically override this function for the buffers which it manages (typically color buffers, Z and stencil). Other buffers (like software accumulation and aux buffers) which the driver doesn't manage can be handled with this function.

This one multi-purpose function can allocate stencil, depth, accum, color or color-index buffers!

This function also plugs in the appropriate GetPointer, Get/PutRow and Get/PutValues functions.

static GLboolean alloc_storage_alpha8	(	GLcontext *	ctx,
		struct gl_renderbuffer *	arb,
		GLenum	internalFormat,
		GLuint	width,
		GLuint	height
	)			[static]

Here we utilize the gl_renderbuffer->Wrapper field to put an alpha buffer wrapper around an existing RGB renderbuffer (hw or sw).

When PutRow is called (for example), we store the alpha values in this buffer, then pass on the PutRow call to the wrapped RGB buffer.

		struct gl_renderbuffer *	src
	)			[static]

static void delete_renderbuffer_alpha8
