Detailed Description

Render to texture framebuffer implementation.

This target allows to render to a texture, which can then be used for further rendering.

Member Function Documentation

◆ destroy()

void OpenGL::TextureTarget::destroy ( )

Notify that the GL context is about to be destroyed.

◆ create()

void OpenGL::TextureTarget::create ( )

Notify that the GL context has been created.

◆ setSize()

bool OpenGL::TextureTarget::setSize ( uint  width,
uint  height 
)
overridevirtual

Set size of the texture target.

Implements OpenGL::Framebuffer.

◆ getTexture()

Texture * OpenGL::TextureTarget::getTexture ( ) const
inline

Query pointer to underlying GL texture.

◆ activateInternal()

void OpenGL::TextureTarget::activateInternal ( )
overrideprotectedvirtual

Activate framebuffer.

This is supposed to set all state associated with the framebuffer.

Implements OpenGL::Framebuffer.
