Hi
Indigo rocks and I'd like to learn a little about monte carlo algorithms and so on.Maybe someone could give me a link to such algorithms in c++ ? I'd like to find also some small open source projects where I could see ray-tracing or radiosity source codes ... In the great lines, how many rendering categories exist and how is it running technically ?
Thanks,
Fabian

i wrote a raytracer a while ago
Here's an image produced by it.
Featurelist-
- Diffuse Shading
Reflection
Point Lights
Area Lights
Soft Shadows
Supersampling
find the source here (.cpp files

Thanks a lot ! Here's what I understand from it :
for each row
for each line
5 times per pixel (supersampling ?)
calculate ray destination
if ray intersects an object then
calculate pixel rgb with object material
...
I guess this algorithm is not complete
Do you have an idea how other rendering methods work in those terms ?
Thanks,
Fabian

Thanks
Interesting but some parts are too complex for me.An algorithm could help

hehe, i thought it's vice versa! do you think that a bunch of source
code lines can be easier to understand than an algorithm outline?

Metropolis sampling is a bit of a pig.
If you want a good grounding learn path tracing first. The best reference I know of is this book:

come on...programming isnt piece of cake!!!espesially for graphics!Fabaf what u looking for?for an complete algorythm?
this is imposible to find!start with simle things and go deeper and deeper!

I was looking for sources like linked above.Interesting to see an early stage project to understand something

don't know if that is what you are looking for but anyway interesting:

perhaps you could try MiniLight

from the perceptuum creator.
