Environment Setup Introduction¶

Complete environment setup for the 3DGS pipeline.

Overview¶

The pipeline requires three main components: 1. CUDA - GPU acceleration 2. COLMAP - Structure-from-Motion 3. 3D Gaussian Splatting - Neural rendering

Installation Order¶

graph LR
    A[CUDA 12.4] --> B[Python/Conda]
    B --> C[COLMAP]
    B --> D[3DGS]
    C --> E[Ready]
    D --> E

Time Required¶

Component	Time	Difficulty
CUDA	10 min	Easy
Python/Conda	5 min	Easy
COLMAP	20 min	Medium
3DGS	15 min	Medium
Total	~50 min	Medium

Quick Start¶

Already know what you're doing?

# Install CUDA 12.4
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt-get update && sudo apt-get -y install cuda-toolkit-12-4

# Install COLMAP
sudo apt-get install -y colmap

# Install 3DGS
git clone https://github.com/graphdeco-inria/gaussian-splatting.git
cd gaussian-splatting
conda create -n 3dgs python=3.10 -y
conda activate 3dgs
pip install torch torchvision --index-url https://download.pytorch.org/whl/cu124
pip install -r requirements.txt --no-build-isolation
