Shading Motion
TL;DR
Exploring motion as a creative medium in graphics programming, this article introduces techniques for shading motion using WebGPU compute shaders. It details methods for extracting motion data to create various visual effects.
✦ Why It Matters
Start experimenting with motion-based effects in your graphics projects using WebGPU today.
Key Takeaways
- Use frame differencing to extract motion from video frames.
- Implement temporal decay to create smoother motion trails.
- Explore various visual effects using the generated motion mask.
- Consider blob tracking for grouping and visualizing moving elements.
How It Works
The pipeline begins by comparing consecutive video frames to identify motion through frame differencing, creating a luminance map that indicates motion intensity. Temporal decay is applied to smooth out the motion representation, allowing for visually appealing trails.
This motion mask can then be used in various post-processing effects, enabling creative interpretations of motion.
