CPT

(

RenderAttrib

)

Constructs a new DepthOffsetAttrib object that indicates the relative amount of bias to write to the depth buffer for subsequent geometry.

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 new DepthOffsetAttrib object that indicates the bias, and also specifies a minimum and maximum (or, more precisely, nearest and farthest) values to write to the depth buffer, in the range 0 .

. 1. This range is 0, 1 by default; setting it to some other range can be used to create additional depth buffer effects.

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

See invert_compose() and compose_impl(). Tells the BamReader how to create objects of type DepthOffsetAttrib.
