Moving the gnomon on the YZ plane:

3D translation

Move the entire gnomon freely in 3D by clicking the origin and moving the cursor.

Moving the gnomon origin:

Rotation about an axis

Click the rotate axis control to rotate the gnomon about an axis.

Rotation about the Y axis:

Rotation about axis to align another axis

Click an arrow at the end of the rotate axis control to rotate the gnomon about an axis and align another axis.

Example rotating about the Y axis and aligning the X axis:

3D rotation to align axis

Click the sphere on an axis and then another point to align the axis in 3D.

Rotating so that the Y axis aligns with a point:
