Software News   Software News : RealTime Ray-Tracing Engine Demo for OS4
   posted by COBRA on 27-Jul-2004 16:45:33 (8784 reads)
A RealTime Ray-Tracing (RTRT) engine called RayRace, developed by Csaba Simon (Chip/Kangoroo), has been ported to OS4. A little demo of this engine is available here for OS4 prerelease owners to try. Read more for screenshots.


Below are two screenshots of the engine in action:

RayRace Screenshot 1
RayRace Screenshot 2

The engine performs true (not faked) ray-tracing in realtime.

I saw this runnign on Rich Drummond's A1 at Amiwest...it's a fun little thang! Looked like an animation player at first...then you realize it's realtime 320x240 (or 200?) trace...nice!

Oooops, the link to the 1st screenshot was wrong indeed, it is now fixed. Thanks guys for pointing it out!

Yes you can change the resolution in this demo, but it runs best around 320x240 (the engine was designed for such resolutions and it gets up to around 50fps with scene 5 :)

Impressive

Imagine making a game in realtime ray-tracing....

That would be

@Cobra:

Is there any way i can reach Chip? If you know how to get in touch with him, can you PM me? Thanks. (I'm desperately searching for screenshots from his 64k intro flow).

Looks very nice, hadn't seen that before

Though I was more thinking about something that could be run on the A1...

I know this isn't an amiga program but there is an incredibly impressive real time raytracing engine demo for the PC writtten by a group of demo coders, check it out it is amazing:

http://www.realstorm.com

Includes volumetric lighting, realtime radiosity etc...

It inspired me to start writing a small raytraced 3D space combat game (low number of intersections = possible to get a decent frame rate). Think Babylon 5 realtime :)

Have you read this:Quote:
This is realtime speed for a virtual intel CPU with about 36 GHz (to be more precise: a cluster with 20 AMD XP1800 was used).

how about porting OpenRT to the amiga ??

Look impressive and looks like it could very well be the platform for future games.

This hardware: SaarCOR
in combination with some nice applications (games, visualisation software, etc.) looks like the killer-hardware/software, that a platform could use.

How do we get that for the Amiga platform?
A port of OpenRT
and a gfx-card based on the SaarCOR chip for the A1
could be a start.

Just some thoughts.

/John.

Cool. With the first Amiga's we got the animated Juggler, now with the new breed of machines we get a realtime raytraced version!

Nice

Yepp, you can move the camera around freely with the mouse. The light source also moves around in a circle, causing the shadows to change, showing that shadows are realtime. All spheres cast shadows on the floor and on each other, and of course all shadows appear also in reflections. And there are reflections within reflections, etc. (it's recursive). A G3/800 runs this scene at around 20fps in 320x240.
