Public Member Functions | |
MinimalBinding (Framebuffer &fbo) | |
Binds fbo as the current framebuffer. | |
virtual | ~MinimalBinding () |
Retracts this binding and restores the previous one. | |
void | setColorComponent (Texture< 2 > &renderTexture, unsigned int location=0) |
Attaches renderTexture as the color component at location of the bound framebuffer object. More... | |
void | removeColorComponent (unsigned int location) |
Removes color component at location from bound framebuffer object. More... | |
Color | readPixel (unsigned int x, unsigned int y, unsigned int location=0) const |
Reads the color of the pixel located at x and y within the color attachment at location. More... | |
const Framebuffer & | framebuffer () const |
References the bound framebuffer. | |
virtual void | refresh () const |
Re-performs this binding. This is useful if the currently bound framebuffer has been changed through a different mechanism, e.g. using OpenGL calls directly or by another API. More... | |
Protected Attributes | |
Framebuffer & | fbo |
References the bound framebuffer. | |
Maintains the binding of a Framebuffer in a RAII-manner.
Bound framebuffers are not checked for validity. Allows manipulation of the bound framebuffer, but not rendering. Use a full Binding if you want to render to the framebuffer.

void Carna::base::Framebuffer::MinimalBinding::removeColorComponent | ( | unsigned int | location | ) |
Removes color component at location from bound framebuffer object.
void Carna::base::Framebuffer::MinimalBinding::setColorComponent | ( | Texture< 2 > & | renderTexture, |
unsigned int | location = 0 |
||
) |
Attaches renderTexture as the color component at location of the bound framebuffer object.
If there was another color component bound to location previously, it is replaced.
