spline mouse

This oddly named thing is simply a line with tension. A set of X, Y coordinates can be used to make a polygon or poly-line. usually the points are connected by straight-line segments. A cardinal Spline takes the positions of the current point and, along with the previous and next points, averages out the positions using a tension value. this smoothes the line and makes a path that is gently curved through the points rather than zigzagging through them

"catmull-rom Spline"The Catmull-rom algorithm guarantees 2 points:1. The 1 stratum number of Pi per point equals pi+1-pi-1.2, through all pi points.Where feature 2 is the maximum difference from Bezier curves. Because of this characteristic, the catmull-rom algorithm is suitable to be used as trajectory line algorithm.The tangent of Point pi: Tau (pi+1−pi−1). The conversion matrix for this algorithm is as follows:　　Let's take a look at how this algori

How to use the VBS to simulate the left mouse button click, left-click, right click? ...... The answer that is commonly found on the Internet is that VBS cannot be implemented, or is it to use a third party COM (ActiveX?) Component I'm disgusted with third-party components, and there's no portability to using third-party components, because this component is not necessarily registered in someone else's system.

Component. I am very disgusted with third-party components. using third-party components has no portability, because others do not necessarily register this component in their systems. I suggest that you do not call third-party components in VBS code unless your program is only written and used by yo

First, open the mouse button (1) Press Ctrl+esc key combination to open the Start menu, press S key and press C to open the Control Panel; (2) Press the ARROW key to move to "auxiliary options", press ENTER to open its Properties dialog box; (3) Press Ctrl+tab to switch to the "mouse" page, press alt+m key combination to select the "Use mouse button" option;

The difference between MouseEnter and mouseoverThese two are triggered when the mouse moves inside the element, the difference being that the MouseEnter event has no bubbling phase, and the MouseOver event has a bubbling phase, which is the first difference.The second difference is that the probability of triggering is different: The mouse from outside the element into the element, will certainly t
