How rongxuancheng/the_code_of_rtweekend works
This is a small C++ path-tracing renderer. Its workflow is to assemble a scene of spheres and materials, configure a camera, trace and shade sampled rays, then write a P3 pixel stream to standard output. The graph reflects the sampled headers and source; no README is present, and no additional capabilities are inferred.
