Raybounce - Raytrace

Revit
1

Hello

i have achieved this using grasshopper and honeybee but with dynamo i see its much challenging.
my goal is to achieve a study that shows the ray tracing from the sun on different components ( transparent glass, reflector surface, light shelf ) just like the pictures below where it shows when it is reflected and where it is passed AND bounced inside the room and i am surely controlling the depth and height parameter for the shelf that i have. i’ve been trying and manipulating alot with the Raybounce Node & got relatively close to what i want to achieve ( i suppose )

The point is to conclude where is the best location for the shelfs and for window heights

  • i have used some custom nodes from a package called ( Acustamo )
  • the bigger issue is to make the rays bounce inside the room, reflecting them isnt as hard
  • the script does not work if i went through with ’ select face ’ and kept going

to sum it up thats what im trying to achieve with dynamo

sorry for making it so long, and help would be really appreciated!

These threads could probably help:

And I wonder if some of the nodes presented here could not also be useful:

The rays from sun come in parallel not from a single point. To get something similar to what you get in Grasshopper you need to:

  1. Create a grid of point on window.
  2. Move them backward using the sun vector.
  3. Now shoot the rays towards your geometry and you’ll get a similar results.
