 | | Is there interest in a raytracing challenge?
|
| Hi all, Would anyone be interested in a raytracing remix challenge? My idea is to provide a relatively simple MPD file and see what all us raytracers and renderers can do with it. Furthermore, I'd like it if the techniques used were described in (...) (19 years ago, 2-Feb-06, to lugnet.cad.ray)

| (...) Hi Sven, Thank you very much it looks very accurate. I think it's a great improvement and I'll add it to my colour definitions. Tim (19 years ago, 20-Jan-06, to lugnet.cad.ray)

| Hi Tim, IMHO the suggested color is too coarse (is this the right word?). It needs to be more blotchy. My suggestion is: #declare Pearl_Light_Gray= texture{ pigment{ bozo color_map { [0.2 rgb <0.55, 0.55, 0.57>] [0.5 rgb <0.6, 0.6, 0.62>] } scale 10 (...) (19 years ago, 20-Jan-06, to lugnet.cad.ray)

|
| Hi all, I was wondering if anyone had a get texture defnition for pearl grey (like the 1x2 bricks with grilles in the Santa Fe cars). It seems to have quite different properties to other Lego colours. Thanks for any help, Tim (19 years ago, 18-Jan-06, to lugnet.cad.ray)
