Painting with Gaussians
TL;DR
A new interactive digital painting tool was developed that uses edge information from images to create brush strokes, enhancing the painting process. The tool allows users to manipulate sliders and see real-time changes in the artwork.
✦ Why It Matters
Experiment with edge-aware techniques in your own digital art projects to enhance detail and interactivity.
Key Takeaways
- Utilize edge information to inform brush stroke placement.
- Implement 2D Gaussian splats for realistic stroke effects.
- Combine structure tensors and Haar wavelets for detail density.
- Experiment with noise to create organic variations in strokes.
How It Works
The tool uses edge information from images to guide brush stroke placement, employing 2D Gaussian splats to simulate the appearance of traditional brushwork. A structure tensor calculates stroke orientation based on image gradients, while a Haar wavelet decomposition provides a detail density map, ensuring strokes are placed where detail is needed.
This combination allows for adaptive stroke sizes and orientations, resulting in a more natural painting effect.
