Can I run this on my Commodore 64 if I upgrade to the Voodoo 5 graphics accelerator?

@Argoon1981 - Lol, ray tracing was the future over 20 years ago.

@slitor aaand....what i said made no sense what so ever.

Firstly because Ray Tracing today relies on CPUs and voodo didnt even have pixel shaders.

Still, its a C64 I'm sure it can be done :)

[slitor]

@AzuMao Why not ? Everything is done in shaders these days ;)

i dont undestand whats so adwanced about this....

@doltBmB The clue's in the name.

[doltBmB]

@2kliksphilip Raster can do nearly everything that raytracing does. For example, looks up "imperfect shadow maps" that show global illumination results using rasterized shadow maps that is close to the kind of results path traced GI can give. But in real time.

[2kliksphilip]

@doltBmB Yes, you can get very good results using cheap tricks. The latest computer games show this, and simply wouldn't be able to look good if they used raytracing.

At the end of the day though, if you have the power, raytracing is going to deliver the best results. It's just at a very expensive cost.

[doltBmB]

@2kliksphilip In the meantime you can run rasterized spherical harmonics lighting that looks just as good and runs ten times faster. Raytracing is just slow, whatever you can do with raytracing you are off better performance wise doing somehow else. Even Pixar chooses their battles, Renderman uses raytracing only for the things that need it. Why would realtime games use it on everything when Pixar doesn't?

[2kliksphilip]

@doltBmB If done right, it looks very good. Sadly, this is the sort of demonstration that I don't like- it makes loads of shadows that look like artifacts, over-the-top cube reflections everywhere and really doesn't show how nice raytraced graphics can look. Nvidia's new car demo is an example of what REAL raytracing can achieve. It's just a shame that the hardware still isn't capable of doing it in real-time... but give it time. (Literally).

@doltBmB Try Googling "Ray tracing and gaming" and click the link to the 'pcper' website. It shows a lot of advantages.

@doltBmB With rasterization, speed decreases quickly over the number of polygons. With raytracing, it decreases a lot less.
