There is probably a much better description for it than that (i.e ask Luke Millar) It's all 3d work, I don't do much 2d work these days, probably should do more but it's time I'd rather spend in 3d world.
Close, but not cigar :D
Ray tracers actually work backwards, tracing light rays back from the camera position to the light source. Forward ray tracing (from the light source) is too hard to do, as most of the photons will never reach the camera.

See, I knew someone was round here that could explain it better. I could have Wiki's it but couldn't be bothered. :p Cheers Wyrness. One thing is for sure, in 2 years or so they reckon we'll have Ray Tracing in games! Wooo.

The "people who know" seem to think that while Intel are working on it, they are actually inventing a problem for them to create a solution to so that they can sell silicon.

It turns out RayTracing may not be the be-all and end-all for games, but RayCasting may.

Ooh, taps raycasting into Wiki and reads on.........

If you look at the shadow on the ground it suggests the sun coming from 4 o'clock but the shadow from the "flower" onto its petals suggests the sun is coming from 2 o'clock - but the light source on the golden rim of the flower suggests light from 4 o'clock :)

Not trying to criticise - just from my own observations as a professional artist. I still think its very clever stuff! :smt023:cool:

Nooooooooooo, I come on here to get away from work! ;)

Nice render! Any comp work or is that out-the-box?

Hey Artylady, sorry to sound like I was a mr knowitall (I'm really quite nice) and you are correct. There are two lights in the scene, one was a physical sun and the other a fill light. And your keen eye spotted that they were ever so slightly misaligned. Them is some good mince pies (eyes). :p

Hey Luke,

I did some comp work in photoshop, mainly just created an instance of the main image, desaturated it and adjusted the levels to darken it a bit. Then changed the blending mode to soft lights and lowerd the opacity. I'm still learning ps though. Also added a bit of diffuse glow. Am tryign to figurte out how to do a depth pass in Modo but no joy so far, would be so much quicker do do the dof in post.

This started as an artwork thread and turned into a geek thread in the first few posts! ;-)

Hehe...no worries...Im a bit of an art pendant and it doesnt really matter as obviously its not meant to be realism anyway! Ive just done a section on Art History analysis in my degree! :geek: :lol:...I'll shut up now! ;)
