car 3D pose annotation has some problem? #1

Hi, I tried to project 3d car models to 2d images ( StanfordCar & CompCars ). Some works and some doesn't work. The visualization looks messy, projected car model is skewed and not well matched.

For example, the first training example (00001.jpg) in Stanford Cars, it uses model 189c2b53ef76d02978a20fe14185667. I found that if I used the 3d car model included in this repo, instead of the one from ShapeNet, the projection visualization looks fine. And then I found many vertices were edited in the 189c2b53ef76d02978a20fe14185667 model in your repo compared to the one in the ShapeNet. So why do you edit the vertices? Couldn't we just edit the extrinsic parameters? How can I make other 3d car models work? Do I need to edit vertices too? Or are you going to release all other edited models too?

Found that projection works for ShapeNet Core V.1. Used ShapeNet Core V.2, and that's why there were so many mismatches. Issue closed.
