NeRF++

Codebase for paper:

• Work with 360 capture of large-scale unbounded scenes.
• Support multi-gpu training and inference.

Data

• Download our preprocessed data from tanks_and_temples, lf_data.
• Put the data in the sub-folder data/ of this code directory.
• Data format.
  • Each scene consists of 3 splits: train/test/validation.
  • Intrinsics and poses are stored as flattened 4x4 matrices.
  • Opencv camera coordinate system is adopted, i.e., x--->right, y--->down, z--->scene.
  • Scene normalization: move the average camera center to origin, and put all the camera centers inside the unit sphere.
