Member Enumeration Documentation

enum BIAS::GLProjectionParametersInterface::ViewingReshapeBehaviour
Enumerator
Deny 

Do not do anything! Do not render either!

AutoRescaleParams 

rescale internal projection parameters preserving aspect ratio and scale by integer values only.

This can lead to two black borders: right and bottom

AutoCutImage 

Render part of the image or the whole image, does not change projection parameters.

drawingUpperLeft_ are the projection image coordinates which will appear in the rendered image in the upper left corner.

AutoSimplePerspectiveCam 

Calculate new simple perspective camera parameters keeping the current field of view in "y direction".

AdaptToCroppedImage 
AutoRescaleSimple 

rescale internal projection parameters preeerving aspectration but use non-integer values.

This should result in only one black border.
