Kefrens - Megademo 8 - Hide Away (Amiga)

The final part of Kefrens Megademo 8.

Besides the nice tune, another reason I'm fond of this demo is the use of wireframe vectors with hidden lines.

I really think wireframes should have been used more on the Amiga. In my opinion, a wireframe display at 50fps appears more attractive than a 12fps scene of flat filled vectors. Compare Mercenary to e.g. Castle Master or Total Eclipse to see what I mean.

A routine for inconvex wireframes with hidden faces would have been extremely impressive! As far as I know, such a thing was never seen on the Amiga.

Maestro, R.I.P.

I didn't know Maestro had died until I read your comment.

His life was short but accomplished!

I remember this intro! i really wanted to learn how to program hided lines so this was the first intro i managed to crack and convert it to a assember source.why i choosed to cracked it was i could see the intro just consisted of 3 routines. Music/scrolleri/3d and knew it would be simple to rip. i got it to work!. Took me a day to crack it, but i learnt to to program my own hided lines and to understand it.

Wow, I'm impressed you were able to reverse engineer this demo, particularly because it was a track loader. I learned how to do hidden lines because of some source code published in a magazine.

Nice tune. Agree totally with the wireframe fps being better aesthetically than slower filled vectors. I loved 3D Starstrike on the CPC464 but hated 3D Starstrike II with filled vectors that ran about 2fps. I personally now cannot abide seeing anything at less than 60fps on my PC, no matter how good the graphics look.

I suspect in future we'll use more "variable precision rendering" (not the technical term... but I don't know the proper name).

If you combine ray-traced technologies with modern screens at 100Hz+, there's no reason to update the whole screen uniformly every frame. The most central/active areas of the screen can be updated at higher rates and better quality than the periphery.

Larrabee may be premature, but IMO ray-tracing just has too many advantages not to be a long-term goal.

Preferred the opening track.
