Dielectrics bis
Dielectrics with Beer's Law.
Dielectrics and Beer’s Law are now integrated into the materials and environment frameworks. In the picture above the indices of refraction increase from left to right.
Physically-Based Rendering
Development of an unbiased physically-based ray tracer
Hi ,
Which BTDF are you using to model dielectrics?I also would be interested to know the render time/number of samples to get to this level of quality because i have always troubles with the rendition of this kind of materials.
Keep up the good work!

This is a standard Fresnel specular model rendered at 3000 spp using an also standard Monte Carlo path tracer. As you can see there are still a few fireflies, the fact that the box is Lambertian does not help.
I have no idea about the time, though (I really should add that info in the renderer’s stats). But it is certainly not excessive for such a simple scene.
keep up the good work!, the images your render engine created looks very nice. how long are the render time for these ?. will there be any option to go biased?. would it be released?
Hi Erwin, and thanks for the kind words.
The renderer is currently pretty basic: The renders I posted so far show off everything it can do. If in the future it matures enough to be usable then I would consider releasing it and add more rendering options… Obviously that’s pretty far off at the moment.
I’ll definitely add render times in my next posts as it seems to be a most requested info
