CALIGARI Demo Tutorial

This is a Demonstration version of Caligari24, a third generation of
Caligari technology. This demo will run on all Amiga models with a minimum
of 2Mb of RAM. You can run Caligari from the floppy disk simply by opening
the disk icon, opening the Caligari drawer, double clicking on
"Caligari-Setup" and then double clicking on "Caligari-Demo". IconX must be
in your C: directory for Caligari-Setup to run.

Initially, the program will enter the Object Design module with the
navigation menu active. Try to move the cursor to the perspective area,
press the left mouse button and move the mouse while holding down the
button. Your View Rotates in the World coordinates around the point you look
at. Release the button and select Move from the menu. Now your view moves
linearly in the space (press Right button for up and down motion).

Select Prim from the bottom menu strip and load one of the primitives into
the work space. Unselect Eye to select Object manipulation. Rot to rotate
it, or Scale to change its size. Try to manipulate the object in World,
Object or Screen coordinate space. Try also different combinations of X, Y,
Z axes while left, right or both mouse buttons are depressed.

Menus can be eliminated [left shift or press close button]. Now you can
use Q W E keys on the keyboard to Move, Rotate Scale; A S D for World,
Object Screen Space; Z X C for X, Y, Z and Space Bar to toggle between Eye
and Object manipulation. These keys work also with menus present.

Load more primitives and select among them by positioning the cursor on top
of an object and pressing left button. Try Render for quick solid view
(broadcast renderer is not available in the demo). Paint polygons from the
Color menu. Use Undo to correct your errors and Erase to delete objects from
the workspace. Try orthogonal views (Top, Side, Front) for more precise
positioning of objects (works like perspective view).

Select PEdit for point editing. Select one, two, three or four points.
Points can be moved, rotated or scaled. Two points define an edge, three
points define a face or a plane cutting through an object. Four points
define a part of an object. Face or part of an object can be Swept or
Separated in two sections. Slice will move the cutting plane through the
object with real time response.

Multiple parts of an object can be selected when Right button is depressed
over a new point (in PEdit). You can continue to press left button to finish
selection of the current part.

Axes button will display origin of local coordinate system for object
or subobject. Axes can also be manipulated just like a regular object.
QuadDiv will subdivide all polygons of currently selected object (or its
part).

Use Load to load predesigned objects. Load the F15 object. This is an object
in VideoScape ASCII format. Load "Robie". Use the arrow down to select its
arm (it takes two steps), then select Rot Z in Obj space to pivot it around
the robot's shoulders. This is called hierarchical access. Selecting Num
will bring up a numeric submenu. Try to Normalize and Center objects and Eye
in World/Object/Screen coordinates. Use 3D Grid to move, scale or rotate in
predefined increments.

From the Tools you can Glue simple objects to create hierarchical objects,
Copy objects, Mirror them or you can access the Extruder. Draw a polygon in
the Extruder (or load a letter from the Eurofont directory) and extrude it
in 3D space using Flat, Extrude or Lathe option.

A simple example of free form deformation is to: select the primitive Cube
and scale it so it is larger. Click on PEdit and then Quaddiv in the PEdit
menu three times. The cube will appear subdivided. Now click on Deform in
the PEdit menu. Click the right button on one of the top corners of the
yellow cube which appears. Select Rot, World and Obj in the Navigation
menu. Click the right mouse button in the design space, and while holding
it down, move the mouse. When you release the mouse button, the cube will
appear bent. Click on Erase twice to delete the deformation lattice and,
voila, you have the deformed cube. Render it in Quick Render to see how it
looks shaded.

Select Scene from the bottom strip. After entering the scene module, select
File and load the Fly scene. Then Select Anim which will bring up the
animation menu. Select I/O and load Fly.script. Select Compile and ">" to
play the compiled script in real time. Select Shuttle or Jog (press both
buttons and drag the mouse).

Editing in animation module can be done simply by jogging to the frame to be
edited, moving/rotating/scaling object and pressing the Set button. You
must Compile to see the newly updated script in motion. If you want to Set
the Eye you must do so while the Eye is selected.

All the operations in the demo are active except Saving and Broadcast
Rendering which is typically used to create the final rendering for a scene.
