- 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:
-
- INSTALL.DOC
- NEW_PICTURE_SET_UP.DOC
- DIGI.DOC
- DEFINE.DOC
- A-RENDER.DOC
- LATHE.DOC
- MORE_DEFINE.DOC
- MOVE.DOC
