Member Function Documentation

activate()

virtual void STK::Texture::activate ( )

pure virtual

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.

Implemented in STK::FBODepthTexture, STK::FBOTexture, Maria::SymbolTexture, STK::CubeMap, and STK::Texture2D.

deactivate()

void Texture::deactivate

(

GLenum

target

)

Deactivates the currently bound texture. Does not delete any resources, simply unbinds the current texture handle.

loadInternal()

virtual bool STK::Texture::loadInternal ( )

protectedpure virtual

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

Implemented in STK::FBODepthTexture, STK::FBOTexture, Maria::SymbolTexture, STK::CubeMap, and STK::Texture2D.

setHorizontalWrap()

void STK::Texture::setHorizontalWrap ( GLenum  wrap )

inline

Set horizontal wrapping type.

Note

This parameter must be set before the texture is activated for the first time, else you must unload the texture and upload it again.

setVerticalWrap()

void STK::Texture::setVerticalWrap ( GLenum  wrap )

inline

Set vertical wrapping type.

Note

This parameter must be set before the texture is activated for the first time, else you must unload the texture and upload it again.

unload()

void Texture::unload

(

GLenum

target

)

Unload the texure from OpenGL. This method will unload all the texture resources related to this texture object from OpenGL.

upload()

virtual void STK::Texture::upload ( )

pure virtual

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.

Implemented in STK::FBODepthTexture, STK::FBOTexture, Maria::SymbolTexture, STK::CubeMap, and STK::Texture2D.
