(

RenderAttrib

)

Constructs a new ScissorAttrib object that removes the scissor region and fills the DisplayRegion.

Intended to be overridden by derived RenderAttrib types to specify how two consecutive RenderAttrib objects of the same type interact.

Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.

Constructs a ScissorAttrib that restricts rendering to the indicated frame within the current DisplayRegion.

(0,0) is the lower-left corner of the DisplayRegion, and (1,1) is the upper-right corner.

This should return the result of applying the other RenderAttrib to a node in the scene graph below this RenderAttrib, which was already applied. In most cases, the result is the same as the other RenderAttrib (that is, a subsequent RenderAttrib completely replaces the preceding one). On the other hand, some kinds of RenderAttrib (for instance, ColorTransformAttrib) might combine in meaningful ways. Tells the BamReader how to create objects of type ScissorAttrib.
