RRCaps Class Reference

This class has been designed to hold all the different things that a render region may or may not be able to render. eg. Some render regions can render transparency, while others can not. This class is used to record what your render region can do. It does this by having a flag for all the area of rendering that some regions can do and other can not. By default this class assumes that you can do nothing, so it is up to you to set the flags for the things you can do to TRUE. TRUE means you can render that type of thing, FALSE means that you can not. The flags to date are :-. More...
