Js math atan2 cos sin 1. Give the relative coordinate center o, p1 to o distance l, p1 to X axis angle (0 ~ 2PI) left：x0+Math.cos(angle)top: y0+Math.sin(angle) 2. The relative coordinate center o and p1 coordinates are given, and the angle between

Induction | Mouse flash in the field of 3D applications is very broad, flash can be very easy to make some wonderful 3D special effects, and many effects can respond to the mouse action, this example is a mouse 3D induction effect, by moving the

This article mainly introduces 97 kinds of curve equations commonly used in proe, the coordinate system used, and the legends for generating curves.  The curve types on each page are as follows:Page 1: disc spring, spiral, helical curve,

(1) RingVertices = D1: 72 D2: 72u = from 0 to (2 * PI) d1v = from 0 to (2 * PI) D2 r = 3 * Cos (u) + 7 z = 3 * sin (u) y = r * sin (v) x = r * Cos (v) y = Y + 5    (2) random radius Ring Two methods are provided: vertices = D1:72 D2:72u = from 0 to

Control and representation of graphics (figure control and representation)The functions and commands provided by MATLAB for graphical control:Axis: Manually select an axis size.CLF: Clear the graphics window.Ginput: Use the mouse crosshair

This procedure by foreign vulture eldest brother to write, and published the source code, this is his 95 years of a work, can say was very successful at that time! This program is clever use of the constant changes in the coordinates, so as to
