0. Training Data Generation <br>
Training data is generated from the [Matterport 3D](https://github.com/niessner/Matterport), [Carla](https://carla.org/) and [NVIDIA Warehouse](https://docs.omniverse.nvidia.com/isaacsim/latest/tutorial_static_assets.html) using developed Isaac Sim Extension, the extensions are part of a new internal project (``isaac-nav-suite``) and will be open sourced with that project. In the case that you require an earlier access, please contact us via mail.

1. Build Cost-Map <br>
The first step in training the policy is to build a cost-map from the available depth and semantic data. A cost-map is a representation of the environment where each cell is assigned a cost value indicating its traversability. The cost-map guides the optimization, therefore, is required to be differentiable. Cost-maps are built using the [cost-builder](viplanner/cost_builder.py) with configs [here](viplanner/config/costmap_cfg.py), given a pointcloud of the environment with semantic information (either from simultion or real-world information).
