[英]Is the movement of the cursor on the screen a result of graphical transformation?
I am occupying myself with image processing right now, to be specific, with geometrical transformation and I was wondering, if the movement of the mouse cursor on the screen, is a result of geometrical transformation which is being calculated by the operating system. 我现在正在处理自己的图像处理,具体来说,几何变换,我想知道,如果鼠标光标在屏幕上的移动是由操作系统计算的几何变换的结果。 If it is, then I guess that behind every movement of a graphical object on a screen there is a system which calculates the geometrical transformation. 如果是,那么我猜在屏幕上的图形对象的每次移动背后都有一个计算几何变换的系统。 Is that right? 那正确吗? And does someone maybe know what keywords to search for, to obtain more information about graphical transformation on eg computers, smartphones? 有人可能知道要搜索哪些关键字,以获取有关计算机,智能手机等图形转换的更多信息吗? Thanks in advance. 提前致谢。
It is entirely system specific. 它完全是系统特定的。 On some systems, mouse cursor movement is done in hardware. 在某些系统上,鼠标光标移动是在硬件中完成的。 On other systems, it is done by drawing operations triggered either by interrupt or poling. 在其他系统上,它是通过中断或极化触发的绘图操作完成的。
