Modeling Rays and Shadows?? #5

Open jbacigalupi opened 9 years ago

How best can we model Rays and Shadows? Is that a task better done with Rhino?

rbartlett14 commented 9 years ago

By rays, do you mean the projected rainbows? This is a good question. Shadows are probably pretty straightforward in either 3DS max or vray for Rhino. The only thing to worry about would be the conversion of the rhino file to 3DS max. (I've done it but with some difficulties).

As for rainbows, I can look into some things online but my first inclination is to have the kites project light as if they were lights themselves in the 3D rendering process and then use photoshop to over lay that light pattern with a rainbow effect.... thoughts?

Are we hoping to have a rendered version of the OBJ kites output for 100% DD then?

Rays: Yes, in general, ideally we do both the shadows (a straight projection) and rainbows (refracted projection per refraction formula). Perhaps a grasshopper definition that takes each object, i.e. kite, and does three functions:

  1. Shadow projection (don't really need grasshopper for this as you've pointed out)
  2. Rainbow projections down (perhaps take your idea of projecting light from each object, but then set direction of light relative to kite plane per formula)
  3. Rainbow projections up, giving point sources from ground.

100% output of objects: Yes, but only to convince ourselves that it is doable. The 100% deliverable does not need this proof laid out explicitly, but we should document our tested workflow and output for our own future efforts in Design Build phase.

okay, if you have a sample set that I should work with, I can start playing around with achieving these three outputs.

or I can just use the non-flocking objects that I already have in the model....
