How to Build a Frame in A-Render :
----------------------------------
The A-Render system is broken into several small programs. Creating an
image has 3 basic steps, outlined below. Be sure to see the explanations
of each program for more details. These 3 steps are:
1. Defining the object(s) that you want in your picture. Objects can
be designed most easily using the 2-D digitizer/extruder program
called Digi (an example of this is the heart picture). Another
option is the program Lathe, which prompts you for points (you type
in the x-y values), and then it rotates them around an axis like a
wood lathe (an example of this is the arrow in the HEART picture).
For the advanced users, there are some 'C' source files for
creating objects (see the BUILD_OBJECTS subdirectory). You can
find the 'C' source code that the bird and 'A' were created with.
2. Defining the 'world'. The program for this is 'Define'. This is
where we define the properties associated with the objects created
in step 1.
These are:
a. The location of the objects in the world.
b. The scale of the objects.
c. The color of the objects.
d. The light reflectivity of the objects.
We also define properties for the view and lighting.
e. The location, direction and perspective value of the
view point for the image (like aiming a camera).
f. Each light's location and color.
3. Rendering. This program is called 'Render'. It is the actual
ray trace program. Render uses a number of the databases created
in steps 1 & 2 to create a solid 3-D image with shading and
shadows.
This is the time consuming part. Some hi-res pictures could take
50 hours or more to complete the render.
The next eight documents in the sequence are a tutorial which will lead
you step-by-step through creating a work disk and the heart picture.
Before using A-Render however, you must make a working copy.
See the document INSTALL.DOC for more information.
This disk has been painstakingly set up because A-Render has a very
specific configuration that would be hard to reconstruct. Because of this,
distribution of modified versions of A-Render is not allowed and will be
considered a copyright violation. Alas, BBS distribution is not allowed
for the same reason (besides its pure size). (Sorry BBS'ers, I'm one
myself).
The eight documents which will lead you through the system are, in order:
