Qt3DCore.QTransform ¶

概要 ¶

详细描述 ¶

QTransform component is not shareable between multiple QEntity ‘s. The transformation is held as QVector3D scale, QQuaternion rotation and QVector3D translation components. The transformations are applied to the mesh in that order. When matrix property is set, it is decomposed to these transform components and corresponding signals are emitted.

Several helper functions are provided to set up the QTransform ; fromAxisAndAngle and fromAxesAndAngles can be used to set the rotation around specific axes, fromEulerAngles can be used to set the rotation based on euler angles and rotateAround can be used to rotate the object around specific point relative to local origin.
