Hello All; I have several questions relating to the subject of 3-D graphics. 1) I'd like to know what type of color scanners are generally used for scanning color photographs which are converted into GIF files ??? 2) I'm going to begin doing some work requiring me to generate 3-D animation on an IBM PC-AT or 386. I have decided that Frame animation would be the fastest and most effective. I'm planning to develop the display routines using "C". Is this in fact, the best way to do it ??? I have a fairly complex object to model (Ie. The Space Shuttle).Is there any way that It would be feasable for me to draw the frames dynamically on a hidden page after performing the necessary rendering calculations before I display the frames on an IBM PC-AT or would this be too slow and not very effective ??? I plan to use Super VGA graphics for the entire project. 3) Can anyone suggest methods for developing a database of frames for every several degrees of rotation of any desired object ??? Is it necessary to take a photograph of every frame and then scan it into your database or is there some other magical way it can be done ??? 4) Are there any expecially good anonymous FTP sites which have IBM PC/VGA Graphics and Animation programs, demos, pictures, and samples ??? 5) Finally, can you recommend any good books on the subject of 3-D graphics and animation which are not too sophisticated ???
