Member Enumeration Documentation

enum SiRenderArea::ClearPolicy

Policy values to clear color and depth buffers beforing rendering.

Enumerator:

NONE	Do not clear both color buffer and depth buffer beforing rendering.
COLORBUFFER	Clear only color buffer beforing rendering.
DEPTHBUFFER	Clear only depth buffer beforing rendering.
COLORBUFFER_AND_DEPTHBUFFER	Clear both color buffer and depth buffer beforing rendering.

enum SiRenderArea::RenderStatus

Returned by the render method.

Enumerator:

ABORTED	The frame rendering has been ended before its completion.
INTERACTIVE	The frame has been rendered in interactive mode (some shapes may have been rendered with low quality settings).
STILL	The frame has been rendered in still mode.
