Member Function Documentation

◆ setupScreen()

void Grim::GfxOpenGLS::setupScreen	(	int	screenW,
		int	screenH
	)

overridevirtual

Creates a render-context.

Parameters

screenW	the width of the context
screenH	the height of the context

Implements Grim::GfxBase.

◆ isHardwareAccelerated()

bool Grim::GfxOpenGLS::isHardwareAccelerated ( )

inlineoverridevirtual

Query whether the current context is hardware-accelerated

Returns: true if hw-accelerated, false otherwise

Implements Grim::GfxBase.

◆ supportsShaders()

bool Grim::GfxOpenGLS::supportsShaders ( )

inlineoverridevirtual

Query whether the current context supports shaders

Returns: true if supports shaders, false otherwise

Implements Grim::GfxBase.

◆ flipBuffer()

void Grim::GfxOpenGLS::flipBuffer ( bool opportunistic = false )

overridevirtual

Swap the buffers, making the drawn screen visible

Implements Grim::GfxBase.

◆ getScreenBoundingBox()

void Grim::GfxOpenGLS::getScreenBoundingBox	(	const Mesh *	mesh,
		int *	x1,
		int *	y1,
		int *	x2,
		int *	y2
	)

overridevirtual

FIXME: The implementations of these functions (for Grim and EMI, respectively) are very similar. Needs refactoring. See issue #789.

Implements Grim::GfxBase.

◆ createBitmap()

void Grim::GfxOpenGLS::createBitmap ( BitmapData * bitmap )

overridevirtual

Prepares a bitmap for drawing performs any format conversions needed for the renderer, and might create an internal representation of the bitmap external changes to the bitmap may not be visible after this is called. Must be called before drawBitmap can be used.

the external bitmap might have its data changed by this function,

Parameters

bitmap the bitmap to be prepared
