Member Enumeration Documentation

◆ ShiftScaleMethod

Methods for VBO coordinate shift+scale-computation.

By default, shift and scale vectors are enabled whenever CreateVBO is called with points whose bounds are many bbox-lengths away from the origin.

Shifting and scaling may be completely disabled, or manually specified, or left at the default.

Manual specification is for the case when you will be calling AppendVBO instead of just CreateVBO and know better bounds than the what CreateVBO might produce.

The automatic method tells CreatVBO to compute shift and scale vectors that remap the points to the unit cube.


Do not shift/scale point coordinates. Ever!


The default, automatic computation.


Always shift scale using auto computed values.


Manual shift/scale (for use with AppendVBO)
