Interface IGlGraphicsSurface
interface IGlGraphicsSurface
Extends com.amazon.apmf.IStandard
Interface that abstracts a graphics surface suitable for rendering with GL ES API. IGraphicsSurface object
created with IGpuDevice for GL ES API is expected to provide IGlGraphicsSurface interface as well.
Methods
getFrameBufferObject()
u64 getFrameBufferObject()
Retrieve the GL Frame Buffer Object (FBO) for this surface. Clients shouldn’t assume that
the default FBO ‘0’ is being used for any onscreen or offscreen surface. Anytime clients call
IContext.makeCurrent() on any IGlGraphicsSurface, FBO of this surface will automatically be used
as the current FBO in GL pipeline. Clients can always switch the FBO to render onto
something else but if it wants to render again on this surface (true for both onscreen and offscreen)
either it needs to call IContext.makeCurrent(IGlGraphicsSurface) again or call
glBindFramebuffer(GL_FRAMEBUFFER, IGlGraphicsSurface.getFrameBufferObject()).
Returns
u64
GL Frame Buffer Object (FBO) for this surface
Throws
DeviceError— if GPU or display subsystem is not in valid stateInvalidOperationError— if no context is bound to this surface or context bound to this surface is different than the the calling thread’s current context.OutOfMemoryError— if device is out of memory
