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.

The camera method will shift scale the VBO so that the visible part of the data has reasonable values.

Enumerator
DISABLE_SHIFT_SCALE 

Do not shift/scale point coordinates. Ever!

AUTO_SHIFT_SCALE 

The default, automatic computation.

ALWAYS_AUTO_SHIFT_SCALE 

Always shift scale using auto computed values.

MANUAL_SHIFT_SCALE 

Manual shift/scale (for use with AppendVBO)

AUTO_SHIFT 

Only Apply the shift.

NEAR_PLANE_SHIFT_SCALE 

Shift scale based on camera settings.

FOCAL_POINT_SHIFT_SCALE 

Shift scale based on camera settings.
