I may be way off in thinking this is feasible, but here’s what I’d like to accomplish. I’ve been asked to look at options for lights in the cabin of a business jet that we’re currently using to test various equipment. I think it would be cool to be able to mock these up with some nice, rendered images, but I don’t know that I’ve got enough data to do this without making too many assumptions to provide a good approximation of reality.
Here’s what I’ve got to work with:
-The plane is modeled in NX, so I’ve exported it as an .stl and imported this into Blender. If anyone has any suggestions for a better alternative to .stl, I’m open to them. NX can make some decent renders, but they take a really, really long time, and there’s much less flexibility in lighting and such. I’ve added an array of spotlights in the cabin.
-For one model of cabin light, the vendor has provided some information concerning the cone of light produced. I know what the brightness is at a distance of 28" along the centerline, as well as at various radii, in foot-candles.
One idea I had was to use this table to mock something up with a single spotlight on a disc. I could dial in the angle of the cone by measuring the light at some points compared to the center until I ended up with ratios like the table provides, but I don’t know what values for falloff, blending, etc. would be reasonable for something like this. I’m not even sure if there’s a way to analyze images like that.
If anyone has any advice for a simple engineer, it would be greatly appreciated.
