Qt3DRender.QPickTriangleEvent ¶

概要 ¶

详细描述 ¶

When QPickingSettings::pickMode() is set to TrianglePicking , the signals on QObjectPicker will carry an instance of QPickTriangleEvent .

This contains the details of the triangle that was picked.

注意

In the case of indexed rendering, the point indices are relative to the array of coordinates, not the array of indices.
