Obtaining mouse coordinates in current coordinate system

由 大憨熊 提交于 2019-12-13 06:14:44
问题 How may I obtain the mouse coordinates in the current coordinate system i.e. in the coordinate system determined by the transformation matrix? mouseX and mouseY return coordinates in untransformed screen space. 回答1: One option is to keep track of the transformation matrix manually and use the inverse transformation to convert between local and global coordinate systems. To convert from the global to the local coordinate system, multiply the global position to the inverse of the local
