CarBEN EV5 Full Sized Prototype Construction - 5 Seat Electric Car From Scratch

Subbing, late but at least not never. @NeilBlanchard where are you.

I just ran across this vehicle and the profile of the vehicle looked a lot like CarBEN EV5. Clearly not an efficient vehicle, but might have drawn some inspiration from this build.

Profile yes, but it lacks the taper in plan.

Wishing you the best .

The CarBEN project is still in my garage. The Saab 99 that I was going to try to use the suspension from - is also still in my yard ...

The thing I am hoping to do is get a 3D scan of the foam, to get a solid 3D model (and tweak it to be symmetrical and smoother) - and hopefully find out what the Cd could be.

Sorry for my lack of participation here on EcoModder - is there a bump up now with the increase in gas prices?

I have been driving EVs only since about October of 2014. And it has been great!

Haven't heard much since the garage fell in on it.

Do you have or know someone with one of those smart phones? duckduckgo.com/?q=smart+phone+photogrammetry

duckduckgo.com/?q=3d+scan+to+3d+model is available from free software to an online service.

My money's on Cd=0.20.

I'm going to have to put gas in the Metro eventually, but the FUV is charging right now. A 50% charge is about $1 on my electric bill.

Any luck with this? I just got a $100 camera that does video. A short walk-around with one of those would get the raw data you need.

The bleeding edge for 3D scanning is Gaussian Splats, but I'm not sure whee that fits in the work flow.

Gaussian splatting
Gaussian splatting is a volume rendering technique that deals with the direct rendering of volume data without converting the data into surface or line primitives. The technique was originally introduced as splatting by Lee Westover in the early 1990s. This technique was revitalized and exploded in popularity in 2023, when a research group from Inria proposed the seminal 3D Gaussian splatting that offers real-time radiance field rendering Continued in Wikipedia

Several software tools support Gaussian splatting for creating 3D models, including DJI Terra, Polycam, KIRI Engine, and PIX4Dcloud. These tools allow users to generate photorealistic 3D reconstructions from images and videos.

It may be as simple as dropping a single picture onto poly.cam/tools/3d-model-generator. You might try a high-angle front and rear 3/4 view and compare the two?
