bool | encodeToBamStream (VectorUchar data, BamWriter writer) |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. More... | |
fillin (DatagramIterator scan, BamReader manager) | |
This internal function is intended to be called by each class's make_from_bam() method to read in all of the relevant data from the BamFile for the new object. More... | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. More... | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. More... | |

This restricts rendering to within a rectangular region of the scene, without otherwise affecting the viewport or lens properties.
Geometry that falls outside the scissor region is not rendered. It is akin to the OpenGL glScissor() function.
The ScissorAttrib always specifies its region relative to its enclosing DisplayRegion, in screen space, and performs no culling.
See ScissorEffect if you wish to define a region relative to 2-D or 3-D coordinates in the scene graph, with culling.
