5. Press MIDDLEMOUSE while the cursor is over the same button.
The surface rotates around the y-axis . Pressing the RIGHTMOUSE
causes the same motion around the z-axis . Do not try to start a
second rotation until the first one is complete and the hourglass
cursor has been replaced by the arrow.
6. Now select the second screen button, the bloodshot eye. Press and
release LEFTMOUSE. Mouse motions now rotate the surface. Press
RIGHTMOUSE to exit this mode and return the surface to its
original spot.
7. Pick the eye icon button again and press and release
RIGHTMOUSE. Now the surface, along with the array of index
planes, rotates as guided by the mouse. RIGHTMOUSE gets you
out of the rotate mode and leaves the display at its new position.
8. Use the third and fourth buttons (counting from left to right) to
further subdivide the basis points that comprise the surface into
twice as many basis points as before. More basis points allow for
more precise editing of the surface, but also increase the complexity
of the model and therefore slow it down.
9. Use the two rightmost screen buttons to make more modifications to
the surface. The fifth screen button is unused. Each of the two
rightmost buttons, the cubes with slices down the middle, selects a
plane of symmetry (in a different axis) across the surface. When a
plane is chosen (by pressing a mouse button as the cursor lies over
one of the iconic buttons), half of the wireframe surface is made
invisible. After a plane of symmetry has been chosen, any changes
to a basis point on the visible side is also made to a corresponding
point on the invisible side.
To make both sides visible again, move the cursor over the button
corresponding to the present axis of symmetry and press a mouse
button.
Rendering Program
After following the procedures for manipulating the basis points of an object as
outlined above, you can use the following procedure to render the surface as a
Gouraud-shaded, z-buffered image in another window.
1. Move the cursor over the second menu button, the bloodshot eye.
Press and release RIGHTMOUSE. Previously you have used this
mode to rotate the surface and the index planes with the mouse.
2. Press and release LEFTMOUSE. The cursor changes shape to
prompt you to anchor this newly created window to the screen.
