GET ROTATE MATRIX

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.
