The following are the intermediate textures generated to produce the final image (Hover over them to get more information). The first pass is the internal structure rasterization pass, and the second pass is the raymarching & compositing pass.

The following are some more images of the final rendering of the molecule using the different rendering modes of the surface.

Surface rendering mode "Depth"

Surface rendering mode "Normals"

Surface rendering mode "Phong"

Surface rendering mode "Flat"

Surface rendering mode "Step Count" (dark = lower count of raymarching steps, bright = higher count of raymarching steps)

Surface rendering mode "Depth" with reflections
