Interactive Maya node: simple rayTracing exercise to calculate annual&daily direct sunExposure.

Inputs: 'recieving surfaces', 'shading' surfaces, direction/s of sun.

Node can trace back from recieving surfaces or trace forward from the sky dome.

optimizations for interactivity:(see videos)
1.use of icosahedron to span sky-dome or sampling-space rather than a regular sphere.

2. heuristic neighboring search for sampling points (i.e search for intersection rays in the neighborhood of sampling points where intersections were previously found).

to do:
1. cache data for interactively visualisation of accrued data (i.e across the day / year)

2. connect to sun angle calculator.
3. add approximate measurement units / metrics.
4. add luminance, avg cloud-cover and other evaluative/characteristic metrics.
5. chart sun-path and establish 'mapping' logics, including data-overlay on unfolded sky-dome.
6. add geometry 'correcting' / suggestive solution-space.
7. add pointCloud export for Catia-parametric model.
