Member Function Documentation

void MIGLX::CONTEXT::CopyBackToFront

(

const LRECT2D *

pRect = 0

)

Copy pixels from back to front buffers.

Has no effect if not double-buffered. Will copy both left and right buffers if stereo.

Parameters:

pRect

Optional rectangle MGD coordinates (0,0 at upper left, inverted from OpenGL)

ERRVALUE MIGLX::CONTEXT::CopyFromMemory	(	MGD::DEVICE_MEM32 *	pDeviceSrc,
		BUFFER	buffer,
		const LRECT2D *	pRect = 0
	)

Copy into context buffer(s) from memory.

Must make context "current" before using.

Parameters:

	pDeviceSrc	Device to copy from
	buffer	Which buffer(s) to copy into/from
	pRect	Optional rectangle MGD coordinates (0,0 at upper left, inverted from OpenGL)

bool MIGLX::CONTEXT::Create

(

MODE

mode

)

Create context with specified mode if available.

Does not make context "current" for subsequent OpenGL functions.

Returns:

true if successful, false if mode not supported.

Parameters:

mode

Required mode

void MIGLX::CONTEXT::Destroy

(

)

Destroy context.

bool MIGLX::CONTEXT::IsCreated

(

)

const [inline]

Determine if has been created.

bool MIGLX::CONTEXT::IsDoubleBuffered

(

)

const [inline]

Determine if context is double-buffered.

bool MIGLX::CONTEXT::IsStereo

(

)

const [inline]

Determine if context uses stereo mode.

void MIGLX::CONTEXT::MakeCurrent

(

XID

xwindow

)

Make context "current" for subsequent OpenGL functions.

void MIGLX::CONTEXT::SetTransIdentity	(	unsigned int	winwidth = 0,
		unsigned int	winheight = 0
	)

Set model/projection transformations to identity such that model coordinates are window coordinates (at z = 0).

Parameters:

	winwidth	Window width if known, in pixels
	winheight	Window height if known, in pixels

void MIGLX::CONTEXT::SwapBuffers

(

)

Swap buffers if double-buffering used.

int MIGLX::CONTEXT::TranslateBuffer

(

BUFFER

buffer

)

const

Translate from MIGLX::BUFFER to OpenGL buffer enum value.
