FrameBuffer

Represents an OpenGL frame buffer. A frame buffer can be bound before rendering to redirect the output to textures instead of the screen. This is meant for advanced rendering techniques such as shadow mapping and screen space ambient occlusion (SSAO).

abstract

class FrameBuffer : Creatable , GLVersioned {

void attach(AttachmentPoint point, Texture texture);

void attach(AttachmentPoint point, RenderBuffer buffer);

void detach(AttachmentPoint point);

Functions

attach void attach(AttachmentPoint point, Texture texture): Attaches the texture to the frame buffer attachment point.
attach void attach(AttachmentPoint point, RenderBuffer buffer): Attaches the render buffer to the attachment point
bind void bind(): Binds the frame buffer to the OpenGL context.
destroy void destroy(): Undocumented in source. Be warned that the author may not have intended to support it.
detach void detach(AttachmentPoint point): Detaches the texture or render buffer from the attachment point
getId uint getId(): Gets the ID for this frame buffer as assigned by OpenGL.
isComplete bool isComplete(): Returns true if the frame buffer is complete, false if otherwise.
unbind void unbind(): Unbinds the frame buffer from the OpenGL context.

Variables

id uint id;: Undocumented in source.

From Creatable

create void create(): Creates the resources. It can now be used.
destroy void destroy(): Releases the resource. It can not longer be used.
isCreated bool isCreated(): Returns true if the resource was created and is ready for use, false if otherwise.
checkCreated void checkCreated(): Throws an exception if the resource hasn't been created yet.
checkNotCreated void checkNotCreated(): Throws an exception if the resource has been created already.

From GLVersioned

getGLVersion GLVersion getGLVersion(): Returns the lowest OpenGL version required by this object's implementation.
