I\'m using an NSTimer to animate an array of objects across the screen. Currently they move from left to right. However, I would like them to move in a circular fashion instead. How can I do this?
Short question:Given a point P and a line segment L, how do I find the point (or points) on L that are exactly X distance from P, if it guaranteed that there is such a point?
Is it possible to distort an image us开发者_JAVA百科ing trigonometric functions like sine and cosine so that it comes out wavy.
Im trying to find out the angle (in degrees) between two 2D vectors. I know I need to use trig but I\'m not too good with it. This is what I\'m trying to work out (the Y axis increases downward):
