Xfo (struct)¶
The Xfo type represents a 3D transform. It uses a Vec3 for translation as scaling as well as a Quat for its rotation. The Xfo can also be expressed as a Mat44, and provides conversion methods for that type.
/*
** Example: Xfo
*/
// create a transform
Xfo xfo;
// change the transform
xfo.tr.x = 3.0;
xfo.ori.setFromAxisAndAngle(Vec3(1.0, 0.0, 0.0), 0.65);
xfo.sc *= Vec3(1, 2, 3);
// project a vector
Vec3 pos = xfo.transformVector(Vec3(0, 10, 0));

clone method
Scalar Xfo.distanceTo? ( in Xfo other )
returns the translation distance between two xfos
Getter as external float32 array
