C3D_CLEAR_DEPTH	Clear the the depth/stencil buffer.
C3D_CLEAR_ALL	Clear both buffers.

Function Documentation

C3D_CalcColorBufSize()

u32 C3D_CalcColorBufSize	(	u32	width,
		u32	height,
		GPU_COLORBUF	fmt
	)

Calculates the size of a color buffer.

Parameters

[in]	width	Width of the color buffer in pixels.
[in]	height	Height of the color buffer in pixels.
[in]	fmt	Format of the color buffer.

Returns

Calculated color buffer size.

C3D_CalcDepthBufSize()

u32 C3D_CalcDepthBufSize	(	u32	width,
		u32	height,
		GPU_DEPTHBUF	fmt
	)

Calculates the size of a depth buffer.

Parameters

[in]	width	Width of the depth buffer in pixels.
[in]	height	Height of the depth buffer in pixels.
[in]	fmt	Format of the depth buffer.

Returns

Calculated depth buffer size.

C3D_FrameBufAttrib()

static void C3D_FrameBufAttrib ( C3D_FrameBuf *  fb, u16  width, u16  height, bool  block32  )

inlinestatic

Sets framebuffer attributes.

Parameters

[in]	fb	Pointer to a C3D_FrameBuf struct.
[in]	width	Width of framebuffer in pixels.
[in]	height	Height of framebuffer in pixels.
[in]	block32	Specifies if using 32x32 tile format.

C3D_FrameBufClear()

void C3D_FrameBufClear	(	C3D_FrameBuf *	fb,
		C3D_ClearBits	clearBits,
		u32	clearColor,
		u32	clearDepth
	)

Sets the clear bits and color for a framebuffer.

Parameters

[in]	fb	Pointer to a C3D_FrameBuf struct.
[in]	clearBits	Specifies which buffers to clear. (see C3D_ClearBits)
[in]	clearColor	32 bit RGBA value to clear the color buffer with.
[in]	clearDepth	Value to clear the depth buffer with.

C3D_FrameBufColor()

static void C3D_FrameBufColor ( C3D_FrameBuf *  fb, void *  buf, GPU_COLORBUF  fmt  )

inlinestatic

Assigns a color buffer to a framebuffer.

Parameters

[in]	fb	Pointer to a C3D_FrameBuf struct.
[in]	buf	Pointer to the buffer to use.
[in]	fmt	Format of the color buffer.

C3D_FrameBufDepth()

static void C3D_FrameBufDepth ( C3D_FrameBuf *  fb, void *  buf, GPU_DEPTHBUF  fmt  )

inlinestatic

Assigns a depth buffer to a framebuffer.

Parameters

[in]	fb	Pointer to a C3D_FrameBuf struct.
[in]	buf	Pointer to the buffer to use.
[in]	fmt	Format of the depth buffer.

Note

Depending on the format chosen, this may be used as a stencil buffer as well.

C3D_FrameBufTex()

void C3D_FrameBufTex	(	C3D_FrameBuf *	fb,
		C3D_Tex *	tex,
		GPU_TEXFACE	face,
		int	level
	)

Binds a texture to a framebuffer. This texture will be used as the color buffer.

Parameters

[out]	fb	Pointer to C3D_FrameBuf struct.
[in]	tex	Pointer to C3D_Tex struct.
[in]	face	Specifies face of cubemap to be used (ignored if it is a 2D texture)
[in]	level	Specifies mipmap level. 0 is the original image, 1 is the first mipmap, and so on.

Remarks

This calls C3D_FrameBufColor with the proper arguments for the buffer of the texture.

C3D_FrameBufTransfer()

void C3D_FrameBufTransfer	(	C3D_FrameBuf *	fb,
		gfxScreen_t	screen,
		gfx3dSide_t	side,
		u32	transferFlags
	)

Transfers a framebuffer to the LCD display.

Parameters

[in]	fb	Pointer to a C3D_FrameBuf struct.
[in]	screen	Screen to transfer the framebuffer to.
[in]	side	Side of the screen to transfer the framebuffer to (unused for the bottom screen)
[in]	transferFlags	Specifies GX_TRANSFER bitflags.
