DESCRIPTION: This dataset is written in 'dtype=torch.float64'. This dataset consists of total 144 deformation scenes from 6 different objects generated through MATLAB. It is divided into 'train' and 'test' dataset, where data['train'][OBJECT IDX = i][DEFORM IDX = j ] and data['test'][OBJECT IDX = i][DEFORM IDX = j ] indicates the same scene, but they are two different subsets of query points.
STRUCTURE: The dataset structure is as follows: VIRDO_simul_dataset = { 'train':{ <OBJECT IDX>: { 'nominal': { 'coords': tensor([1, M, 3]), 'normals': tensor([1, M, 3]), 'gt': tensor([1, M, 3]), 'scale': float }, <DEFORM IDX>: { 'coords': tensor([1, M, 3]), 'contact': tensor([1, M_c, 3]), 'normals': tensor([1, M, 3]), 'gt': tensor([1, M, 3]), 'scale': float, 'reaction': tensor([1,3] }, },
}, 'test':{ <OBJECT IDX>: { 'nominal': { 'coords': tensor([1, M, 3]), 'normals': tensor([1, M, 3]), 'gt': tensor([1, M, 3]), 'scale': float }, <DEFORM IDX>: { 'coords': tensor([1, M, 3]), 'contact': tensor([1, M_c, 3]), 'normals': tensor([1, M, 3]), 'gt': tensor([1, M, 3]), 'scale': float, 'reaction': tensor([1,3] }, },
}, }
