[comp.sys.sgi] Mirroring in Showcase

eddc@opus.lerc.nasa.gov (Dave Carek) (03/22/91)

Is it possible to create a mirror image of objects in Showcase?  If so
could someone tell me how?

The right flame on the second plane of David Ciemiewicz's "TOP DOG"  seems
to be a mirror of the of the left flame.

Creating a mirror of an object is done by negatively scaling the object along
one axis.

To achieve a mirror copy of an object, make a copy of the object then just
select the second object.  Click down on one of the side stretch handles
and drag the handle across the face of the object toward the opposite side
of the object and continue dragging until negative scaling of the object is
the size you want.

			 Obj     Copy
			+-----+o--o--o
			|     ||     |
			|     |o     o<- Click down here and drag to left
			|     ||     |
			+-----+o--o--o

			<--- drag ---

			 Copy is now on top of Obj
			o--o--o
			|     |
    Stop dragging here->o     o
			|     |
			o--o--o


I have found it easies to place the original and the copy side by side so
I get both objects approximately equal.  Gridding helps too.  Unfortunately
there is no flip option.

Copy the object to be mirrored.
Paste the copy.

Make a rough approximation by dragging the right center green blip
of the new object to the left side of the object.

Select the original object then shift-select the new object.

(At this point the original object shuld have larger green blips around it
than the new object.)

Open the Align Gizmo.

Choose lefts and rights.

Choose Apply.

The new object will stretch to exactly match the original object in width
and position.
