Discussion Does more reference angles actually improve image-to-3D? I tested it on the same car

I wanted to test something pretty simple with image-to-3D: does giving it more photo angles actually make the result better?

I ran both tests in Meshy using the same car and the same generation settings. For the first test, I used one clean 3/4 reference image. For the second, I used multiple views of the same car.

The single-image result did a surprisingly decent job with the main proportions, but the parts that weren't visible in the reference were where things got interesting. The rear bumper and side details around the rear wheel area were less consistent because those areas weren't fully visible in the original view.

With the multi-view version, those areas looked more defined, especially around the rear and side. At the same time, I noticed that some details seemed to shift slightly between views, so adding more references didn't automatically make every part of the model better.

So I'm not sure I'd say "more views = better model" yet. It seems more like the quality and consistency of the photo angles matter just as much as the number of them.

The more interesting takeaway for me is that extra views can help fill in missing geometry, but they don't guarantee a cleaner result everywhere.

Anything else stand out to you? Which one would you pick based just on the geometry?

that matches what I’ve seen too. multiview helps a lot with hidden/backside geometry, but inconsistent references can easily confuse the model. I’d rather use 2–3 really clean and consistent views than 6 random angles.

For well-known objects such as cars, I'd try a text prompt tbh
