Learn how images are made
Interactive tools for understanding rendering, imaging, and visual computing.
Rendering
Metropolis Light Transport
Explore how light simulation evolved — from basic rasterization to Monte Carlo path tracing to Metropolis sampling. Build a Cornell box and watch photons find their way.
Color Science
Spectral Color Spaces
Visualize how human color perception maps to CIE chromaticity diagrams, gamuts, and spectral power distributions.
Optics
Lens Simulation
Trace rays through thin and thick lens systems. Understand aberrations, depth of field, and bokeh formation.
