http://stackoverflow.com/questions/2259476/rotating-a-point-about-another-point-2d 如果你也是使用Unity做为开发引擎,可以参考如下代码:如下代码是考虑基于Y轴旋转的,所以你可以将点(x,z)看做平面内的一个支点,angle表示要基于(x,z)点旋转的角度,point是要旋转的点,具体代码如下: Vector3RotatePoint(floatx,...

- In computer graphics, rotating an image or shape around a pivot point is a common task. (在计算机图形学中,围绕一个枢轴点旋转图像或图形是一项常见任务。) 在数学中,"rotate"可以用来描述向量或坐标系的旋转变换。 - To rotate a vector by 90 degrees counterclockwise, you can multiply it by a ...

three-element vector of Cartesian coordinates Origin of the axis of rotation, specified as a three-element vector of Cartesian coordinates[x y z]. The default origin of the axis of rotation is the center of the plot box. This point is not necessarily the origin of the axes. ...

I'm trying to rotate a vector around one axis parallel to x axis. To my understanding, the rotation around x axis in 3d space is by applying: a = 1; xcord = [0 a]; ycord = [0 0]; zcord = [0 0]; pos = [xcord; ycord; zcord]; theta = 30; Rot = [1, 0, 0; ...
