- 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.
-
- We hope that you will enjoy this demo and decide to order the full
- Caligari24 which comes fully documented and supported by Octree Software. If
- you have additional questions please contact out technical support line at
