OpenGL-specific implementations for DrawI.

Member Function Documentation

◆ drawAlignedText()

void fe::ext::DrawOpenGL::drawAlignedText	(	const SpatialVector &	location,
		const String	text,
		const Color &	color
	)

virtual

Draw screen-aligned single color text.

Text is drawn at the given location, transformed and projected by the current state of the underlying graphics system.

Reimplemented from fe::ext::DrawCommon.

◆ drawRectangles()

void fe::ext::DrawOpenGL::drawRectangles	(	const SpatialVector *	vertex,
		U32	vertices,
		BWORD	multicolor,
		const Color *	color
	)

virtual

Draw rectangles.

Uses vertices and colors as explained in drawPoints.

Rectangles are never stripped.

Reimplemented from fe::ext::DrawCommon.

◆ flush()

void fe::ext::DrawOpenGL::flush ( void )

virtual

Called once after each frame.

This shifts data access to freeze the current input buffer and prepare a new empty input buffer.

The resulting output buffer is sent on to the next DrawI interface.

Reimplemented from fe::ext::DrawCommon.

Reimplemented in fe::ext::DrawHydra.

References fe::errorString(), and fe::ext::DrawNull::view().

Referenced by fe::ext::DrawHydra::flush().

◆ font()

virtual sp<FontI> fe::ext::DrawOpenGL::font ( void )

inlinevirtual

Get current font.

Reimplemented from fe::ext::DrawCommon.

References fe::ext::DrawCommon::drawLines(), fe::ext::DrawCommon::drawPoints(), and fe::ext::DrawCommon::drawTriangles().

◆ isDirect()

virtual BWORD fe::ext::DrawOpenGL::isDirect ( void ) const

inlinevirtual

Returns TRUE is display is local and rendered directly.

Reimplemented from fe::ext::DrawCommon.

◆ multiplication()

Real fe::ext::DrawOpenGL::multiplication ( void )

virtual

Select the GL-specific index/handle.

An index of 0 indicates no font. upscaling preference, such as for high DPI

Reimplemented from fe::ext::DrawCommon.

◆ popMatrix()

void fe::ext::DrawOpenGL::popMatrix ( MatrixMode a_mode )

virtual

pop the top 4x4 matrix from a particular stack

Reimplemented from fe::ext::DrawCommon.

◆ popMatrixState()

void fe::ext::DrawOpenGL::popMatrixState ( void )

virtual

Pop transform matrices.

Reimplemented from fe::ext::DrawCommon.

◆ pushMatrix()

void fe::ext::DrawOpenGL::pushMatrix	(	MatrixMode	a_mode,
		Real	a_values[16]
	)

virtual

push a new 4x4 matrix on a particular stack

Reimplemented from fe::ext::DrawCommon.

◆ pushMatrixState()

void fe::ext::DrawOpenGL::pushMatrixState ( void )

virtual

Push transform matrices.

Reimplemented from fe::ext::DrawCommon.

◆ setBrightness()

void fe::ext::DrawOpenGL::setBrightness ( Real a_brightness )

virtual

set additive lightening

Reimplemented from fe::ext::DrawCommon.

References fe::ext::DrawCommon::setBrightness().

◆ setContrast()

void fe::ext::DrawOpenGL::setContrast ( Real a_contrast )

virtual

set multiplicitive light scaling

Reimplemented from fe::ext::DrawCommon.

References fe::Registry::create(), fe::Component::registry(), and fe::ext::DrawCommon::setContrast().

◆ setDrawMode()

void fe::ext::DrawOpenGL::setDrawMode ( sp< DrawMode > mode )

virtual

Set rendering mode.

Reimplemented from fe::ext::DrawCommon.

◆ unbindVertexArray()

void fe::ext::DrawOpenGL::unbindVertexArray ( void )

virtual

currently, sets vertex array to zero in OpenGL

Reimplemented from fe::ext::DrawCommon.
