Nerfstudio is your key to the fascinating world of Neural Radiance Fields (NeRFs). This guide will walk you through the process of getting started, from installation to training your first NeRF model.

Quickstart Overview

• Installation
• Training Your First Model
• Exporting Results
• Using Custom Data
• Advanced Options

1. Installation: Setting Up the Environment

The first step to unleashing the power of Nerfstudio is setting up your environment. Make sure you have an NVIDIA video card with CUDA installed on your system.

Prerequisites

Tested with CUDA version 11.8. More info can be found on the CUDA Quick Start Guide.

Create Environment

To create your environment using Conda, run:

conda create --name nerfstudio -y python=3.8
conda activate nerfstudio
pip install --upgrade pip

Install Dependencies

Install PyTorch with the following command:

pip install torch==2.1.2+cu118 torchvision==0.16.2+cu118 --extra-index-url https://download.pytorch.org/whl/cu118
conda install -c nvidia/label/cuda-11.8.0 cuda-toolkit
pip install ninja git+https://github.com/NVlabs/tiny-cuda-nn#subdirectory=bindingstorch

2. Training Your First Model!

Now that your environment is set up, it’s time to train your first model. Nerfstudio provides a recommended model called nerfacto.

# Download some test data
ns-download-data nerfstudio --capture-name=poster

# Train model
ns-train nerfacto --data data/nerfstudio/poster

Watch for training progress and navigate to the end terminal link to load the web viewer.

3. Exporting Results

Once your model is trained, you can export results. You can render a video or generate a point cloud.

Render Video

Create a camera path in the web viewer and follow the prompts to render your video.

Generate Point Cloud

Select the POINT CLOUD option from the EXPORT tab in the viewer to generate a point cloud.

4. Using Custom Data

Using your own data is essential, especially if you want to personalize your projects. Prepare your datasets and convert them using commands provided in the documentation.

5. Advanced Options

Dive into advanced features such as training other models or modifying configurations based on your project needs.
