Command

GET_ROTATE_MATRIX <matrix array>, <vx>, <vy>, <vz>, <angle>


Set an array variable to the transformation matrix required to perform a 3D rotation.

Parameters

<matrix array>
A transformation matrix contains 12 values. These are stored in an array variable that must be defined to hold at least 12 values. If the array variable is defined with a size of more than 12, the first 12 values are used for the transformation matrix.
<vx>
the X component of a vector.
<vy>
the Y component of a vector.
<vz>
the Z component of a vector.
<angle>
angle value, either degrees or radians. Positive angles indicate a CCW direction, negative for CW.

Use the DEGREES or RADIANS commands to switch between the two angle modes.

Example

DEGREES
LOCAL MAT1(12)
GET_ROTATE_MATRIX MAT1, 0, 0, 1, 30


This will get a matrix to rotate 30 degrees around the Z axis.
