Normal Mapping
A plane with and without normal mapping in the form of a brickwall. Normal mapping was used for nearly every object in my scene as it improves quality without adding computational complexity.
Area Lights
The same image rendered with a point light and an area light using 128 samples.
Halton Sampler
The same image rendered with the inedependant sampler and a halton sampler with permutations. The halton sampler takes longer but produces better images.
Denoising
Image with an without the image denoiser applied. The denoiser uses the albedo and normal integrator to reduce the noise.
