MAXScript Frequently Asked Questions
I am trying to rotate a unit vector around 360 degrees in steps of 2 degrees. It only needs to rotate around the Z axis, X and Y stay the same.
The Matrix3 Values topic provides convenient ways to transform vectors (Point3 values) including rotation about the world Z axis! You can simply construct a rotateZMatrix value and transform the original vector using it:
resetMaxFile #noPrompt --reset the file
theV = normalize [5,0,10] --the vector to rotate, normalized to unit vector
theStep = 10 --the step by which you want to rotate
--rotate from 0 to 360-theStep with step TheStep:
for a = 0 to 360-theStep by theStep do
rm = rotateZMatrix a --create a rotation matrix from the value
theRotV = theV * rm --transform the original vector using the matrix
format "%: %\n" a theRotV --print the result to Listener
c = cylinder() --create a cylinder
c.dir = theRotV --orient along the vector to see what it looks like
The results looks like a muffin!
