DESCRIPTION¶

This engine has inputs that specify values for translation, rotation, scale, and center of transformation. As output, it produces a transformation matrix that transforms objects into the space specified by the scale, rotation, and translation inputs (in that order).

The input fields can have multiple values, allowing the engine to compose several matrices in parallel. Some inputs may have more values than others. In such cases, the last value of the shorter inputs will be repeated as necessary.

INPUTS¶

SoMFVec3f translation

Translation in x, y, and z.

SoMFRotation rotation

Rotation.

SoMFVec3f scaleFactor

Scale factors in x, y, and z.

SoMFRotation scaleOrientation

Rotational space for scaling.

SoMFVec3f center

Center point for scaling and rotating.

OUTPUTS¶

(SoMFMatrix) matrix

Transformation matrix that transforms from object space into the space specified by the inputs.
