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; ...

The idea is to have a sine wave on the top and a sine wave at the bottom and loft them to make an undulating surface.. The bottom surface is a plane. I have tried rotating the vector by using the same unit vector on the top and rotating it by 90 degree but the thing doesnt work...
- 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 ...
