Detailed Description

The SoScale class is a node type for scaling scene graph geometry.

Use nodes of this type to apply scaling operations during scenegraph traversals for e.g. rendering. Scale values are specified in a triple-value vector, with one scale factor for each of the 3 principal axes.

FILE FORMAT/DEFAULTS:

    Scale {
        scaleFactor 1 1 1
    }

Member Data Documentation

SoSFVec3f SoScale::scaleFactor

Specifies scaling along the 3 axes.

To get a uniform scale applied to the affected shapes, set the scaleFactor field to a vector with the same value for all components.

A common error when doing non-uniform scaling in a single direction is to set the value for the other two components of the scaleFactor vector to 0. This is obviously wrong, they should be set to 1 to not scale the shape(s) in the other two directions.

Be careful with setting scaleFactor component values to 0 or to negative values. Most shapes should handle those cases somehow, but the results are undefined unless otherwise specified.

The default value of this vector field is [1.0, 1.0, 1.0].
