CUDA Voxel Processing - Quick Start Guide

Installation (5 minutes)

# 1. Navigate to project directory
cd /home/user/Pixeltovoxelprojector

# 2. Build CUDA module
./cuda/build.sh

# 3. Verify installation
python3 -c "import voxel_cuda; voxel_cuda.print_device_info()"

Basic Usage (10 lines of code)

import voxel_cuda
import numpy as np

# Create GPU voxel grid (500³ voxels)
grid = voxel_cuda.VoxelGridGPU(500, 6.0, np.array([0, 0, 500], dtype=np.float32))

# Setup 10 camera streams
mgr = voxel_cuda.CameraStreamManager(10)

# Configure cameras (example for camera 0)
position = np.array([1000.0, 0.0, 0.0], dtype=np.float32)
rotation = np.eye(3, dtype=np.float32).flatten()
mgr.set_camera(0, position, rotation, fov_rad=1.0, width=7680, height=4320)

# Process frames (8K resolution)
prev_frames = np.zeros((10, 4320, 7680), dtype=np.float32)
curr_frames = np.random.rand(10, 4320, 7680).astype(np.float32) * 255
mgr.process_frames(prev_frames, curr_frames, grid, motion_threshold=2.0)

# Get results
voxel_data = grid.to_host()  # Returns numpy array (500, 500, 500)

Troubleshooting

Module not found after build

# Add to Python path
export PYTHONPATH=/home/user/Pixeltovoxelprojector:$PYTHONPATH

CUDA out of memory

# Reduce voxel grid size
grid = voxel_cuda.VoxelGridGPU(256, 6.0, grid_center)  # 256³ instead of 500³

Slow performance

# Check GPU is being used
voxel_cuda.print_device_info()

# Optimize for 8K
voxel_cuda.optimize_for_8k()

Next Steps

Read /cuda/README.md for detailed documentation
