-
(Glossy Materials) Glossy materials have a reflective component and a diffuse component, we choose a suitable ratio between the two to obtain the desired glossy effect
-
(Beer's Law) Calculate the light absorbance of a material, depending on the color obsorbence of the material
-
(Depth of field) Shoot a ray through the pixel with a fixed focal length to find the focal point, fire multiple random rays within a circle about the camera determined by the aperture size throught the focal point and obtain an average color
Rendering time 10 minutes and 13 seconds.
With the following command:
dotnet run -- -f tests/final_scene.txt -o output.png --aperture-radius 0.01 --focal-length 0.8
dotnet run -- -f tests/sample_scene_1.txt -o images/sample_scene_1.png -x 4
dotnet run -- -f tests/sample_scene_2.txt -o images/sample_scene_2.png -x 4
