Photography has always been a fun hobby for me and recently I unearthed an old film camera. Studying light, thinking about how film works, and loving a good FS challenge, I was curious if I could recreate the Polaroid camera in Onshape. At the same time the Onshape team hosted an internal design contest open to all categories. The time pressure was on!
Calculating light in 3D environments is certainly not new. This site has a fantastic write up on how light is calculated on computers and heavily informed the development for this feature:

The final result:
Also happy to take home first prize in the internal design competition 🙂

And of course a big thank you to @Jake_Rosenfeld for guidance and code review help!
A second thank you to @AlexPitt for developing ErgoMan which I used as my studio model.

The basic algorithm for this feature is to cast a ray from the camera into the scene and calculate the intensity of light at the intersection with model geometry. To keep things simple the image is only black and white. Shadows are considered as well as light attenuation (falloff over a distance).

This is really cool and creative!
Is there a way to automatically create Bitmap Files with a FeatureScript? Can we export the rgb matrix as text file?
