Hi there,
What's new:
- Added Beer's law to the glass material - you can tell how absorption varies with the distance traveled (for ex. monkey's ear is barely colored versus it's middle).
- Pixel filtering - added variety of filters. The black border around the light source is due the negative values of mitchell filter.
- Reimplemented simple bvh and .obj parser.
Btw. could somebody tell me:
when I specify my light intensity with pure rgb triplet as its emittance, for ex. (15, 15, 15) - what units are those? And how could I convert between other, perhaps more physically convenient, units? so I could compare my results with other renderers.
Cheers.
Wow , you're progressing very well Michael :) . I think Beer's law made the monkey looks very realistic.
ReplyDeleteThe emittance you're talking about is equivalent imo to radiance , so its components (R,G,B) are expressed in spectral radiance unit Watt/(m^2*sr*nm).
agree with dpower- it's radiance
