IYIGPUObject implementation for OpenGL Framebuffers.

Upon creation, a framebuffer will generate a valid handle in graphics memory
screenBuffer is a boolean flag indicating whether the framebuffer represents the screen.

Upon deletion, a framebuffer will free all of its memory and invalidate its handle.
- Warning
- The textures contained inside the FBO are managed separately, only the FBO will be destroyed

Deallocates the GPU memory associated with this object.

Generates a valid handle. No GPU memory is allocated until Load() is called.

This function can be called to invalidate the buffer handle without freeing the associated memory.
This can be used if the GL context is lost and GPU memory is freed implicitly. Calling Free() on this object will result in a crash if the handle is no longer pointing to valid memory, and a new handle may not be created with Generate() if the current handle is valid. This function allows you to inform the buffer object that the GL data has been freed externally and that the handle should be disconnected.
- Warning
- Calling this function without being sure that the handle has been freed in GPU memory will result in a memory leak. Use at your own risk.
Implements IYIGPUObject.
| virtual void CYIGLFramebufferObject::Load |
( |
const std::shared_ptr< CYIAssetHardware > & |
pHWAsset | ) |
|
|
overridevirtual |
Loads the software data from the associated CYIAsset into graphics memory. If the YI_GPU_OBJECT_STATUS is LOADED_FRESH upon a call to load, meaning that data was previously successfully loaded, the status may become LOADED_STALE in the case where this load failed. See the YI_GPU_OBJECT_STATUS documentation for more details.
Implements IYIGPUObject.

Frees any previously loaded data from video memory, but retains the handle.

Makes the GPU Object active, called by the renderer
