The concept for the image went through various iterations (which can be seen below), although always keeping the theme of connection between beings. In the first concept, many ladybugs would gather arrround a Mandelbulb fractal, as if entranced by it, and connected by it. The image, however, did not work visually. We kept the theme of connection, but we reduced the number of ladybugs. Instead of showing a connection between them, we show them in different places, with one drifting though a lake.
Early concept, rendered with the Cycles engine in Blender 3D.
As seen below in the "Inspiration" section, ladybugs can be very very pretty.
All 3D models were modeled by the group. Some third party images were used for some textures. The list of sources can be found in the project, in assets/sources.txt.
This detail shows indirect illumination. In "rt/integrators/pathtrace.h", you can find the integrator that computes global illumination in an unbiased way.
We implemented a simplified version of Disney's BSDF's model (as described in --- ), so that we could model realistic materials with ease, with easy to understand parameters. See "rt/materials/disney.h" for more details.
Details can be mapped on the surface with Normal Maps. See "rt/materials/normalmapped.h" for more details.
