Riassunto analitico
We present a novel GPU based rendering algorithm, specifically designed for visualizing very large molecular models with global illumination. Our algorithm is based on screen splats representing an entire spheres (as opposed to a small portions of a surface, as in typical point splatting algorithms). <br>The key is the exploitation of the very limited screen space size (a few pixels) of the sphere elements at the required scales.<br>Global illumination is quickly precomputed as an irradiance function defined over the surface of each sphere, and efficiently stored though spherical harmonics.
