Detailed Description

The SoShapeScale class is used for scaling and rotating and translating a shape based on projected size.

The marker shape should be behind this node in the scene, and should be approximately of unit size, and with a center position in (0, 0, 0).

char SoShapeScale::changescale [protected]

SoSFBool SoShapeScale::dorotate

SoSFFloat SoShapeScale::maxScale

SoSFFloat SoShapeScale::minScale

SoSFBool SoShapeScale::restoreProportions

If true, the scale will be reset to (1,1,1), wich will make the shape's proportions equal in all dimensions

SbVec3f SoShapeScale::scaleby [protected]

SoSFFloat SoShapeScale::screenSize

The desired width on screen. Default is 5 pixels. If screenSize is equal to zero, the equal- screen-size-scaling is turned off.
