What is the input format for Mesh RCNN?

I would like to implement MeshRCNN but it states Pytorch 3D as a dependency. Does that mean that the input has to be obj files ? Or can they be images ?

Thanks!

The imput format has to be an image, MeshRCNN does several operations (with detectron2 and MaskRCNN segments the image and then take the highest priority object in the picture and it transform to a mesh) but the final output will be an .obj file .
I did it in colab if you need help https://youtu.be/YFSJgF39G7c @Kiran_Ikram
