Detailed Description

SymbolTexture - Dynamically updated symbol texture.

Member Function Documentation

activate()

void SymbolTexture::activate ( )

overridevirtual

Activate texture. This method will upload the texture data to OpenGL if not already done, and set this texture as current texture for all texture operations on the current texture unit.

Implements STK::Texture.

beginTextureUpdate()

bool SymbolTexture::beginTextureUpdate

(

)

Method 2: Update via FBO (faster)

loadInternal()

bool SymbolTexture::loadInternal ( )

overrideprotectedvirtual

Load from disk and upload to graphics card. This method should load the texture resources from disk.

Implements STK::Texture.

updateTexture()

void SymbolTexture::updateTexture	(	const STK::Image &	image,
		int	xOffset,
		int	yOffset
	)

Method 1: Update via glTexSubImage (slow)

upload()

void SymbolTexture::upload ( )

overridevirtual

Upload texture data to graphics card. This requires a valid OpenGL context. If threaded GL and shared contexts are supported this can be done from the texture loader thread.

Implements STK::Texture.
