PNNAGATA@MTUS5.BITNET (02/25/91)
Hello, I'd like to introduce myself... My name is Jeff Litz and I'm new to this environment... If some of you haven't already figured out, I'm using a friends account to post on here... See, where I have an account, we're not "PREVILEGED" (that should be PRIVILEGED, my backspace doesn't work properly). My path is litz@vacs.uwp.wisc.edu Anyway, I was wondering if anyone on here has heard of Video128? Well, if not, it's a 3D animation generator... Kind of like VideoScape for the Amiga. Just wondering if anyone has seen any of my animations and would like to know what you think. Also, did anyone see my program SupraTechnic? (Published in COMPUTE!'s Gazette, Nov 88, if I remember right.) It "bit-mapped" the top and bottom borders on the C64. It doesn't use sprites to pull it off either. If anyone wants to to a PRIVATE reply (i.e. e-mail) to me, PLEASE send it to litz@vacs.uwp.wisc.edu I'm not sure my friend would like getting mail not intended for him.

As I recall, if you told VIC to switch from 24 row to 25 row mode on scan lines below 192, you got a borderless bottom. If I recall, though, you had to keep the background color black because there was some "black garbage" down there. :-) I haven't heard of getting a bitmap, though. (With the above method, you could use sprites in the top/bottom border...) Interestingly enough, the same things happens for the side borders as for the top/bottom borders if you switch VIC from 38 to 40 column mode at the corresponding columns. Unfortunately, this is almost impossible on a 1MHz 64, and even on a 4MHz 64 eats up too much CPU time to be real useful... (Since you need to interrupts twice every scan lines... :-( ) And of course, not many people have 4MHz 64's anyway! ---Joel Kolstad kolstad@jomby.cs.wisc.edu

You don't need a 4MHz 64 ! Actually, a few years back, a cracking group called '1001' released a program called 'ESCOS' (Expanded Screen Construction Set) which let you take a bitmap and display (part of it) full screen (and I mean FULL SCREEN, including borders etc.) I don't think it worked on 'NTSC' 64's, because of timing problems. Personally, I used the 'trick' for displaying errormessages in the border. A sample of that can be found in my Graphics Transformer II, a program which is able to transform (or just plain show) pictures of about 44 different graphicspackages (like Artstudio I & II, Doodle...) formats to eachother. It will even let you display complete PrintMaster and PrintShop pictures. More important, it's free ! It should be uploaded (or maybe already is) to milton pretty soon (right, Scott ?). -- Ronald van Loon (rloon@praxis.cs.ruu.nl) There never seems to be enough time to do the things you want to do - once you find them - Jimmy Croce "Time in a bottle" -- Ronald van Loon (rloon@praxis.cs.ruu.nl) There never seems to be enough time to do the things you want to do - once you find them - Jimmy Croce "Time in a bottle"

In reference to removing the side borders, a friend of mine has written a little program that does just that... also, there is a demo from Europe called Bone Hard, and they do some amazing things with vertical rasters and displaying stuff in the side borders... And everyone thought that vertical rasters were impossible... guess not.. -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + Mike Digdon: digdon@ug.cs.dal.ca + My 64 can still get the + + mike@ac.dal.ca + job at hand completed!! + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
