A real-time radiance field technique that replaces traditional voxels with millions of learned 3D Gaussians for photorealistic rendering at 100+ FPS.

3D Gaussian Splatting (3DGS) represents a paradigm shift from NeRF by ditching costly neural network queries for a rasterization-based approach. The system initializes a point cloud from SfM data (Structure-from-Motion) and optimizes 3D Gaussians (defined by position, covariance, color, and alpha) to fit the scene. By using a tile-based sorter and a custom CUDA kernel, it achieves sub-millisecond rendering speeds on consumer hardware like an RTX 3080. This allows for instant navigation of complex environments with high-frequency details (reflections and thin structures) that traditional meshes often struggle to resolve.

### [Reconstructing Memories with 3D Gaussian Splatting](https://hong-kong.aitinkerers.org/talks/rsvp_zmGEdhKSUks)

The Foundation: Using 3D Gaussian Splatting (3DGS) to recreate real-world environments with hyper-realistic fidelity with PostShot. Showing the PLY file on SuperSplat also showing how ply file structure. Meta SAM 3D: Integrating Meta’s SAM 3D to isolate and create specific 3D objects. Also showing the Spatial Reasoning ability and when it fails. Apple’s SHARP: Using Apple’s SHARP via CLI to transform flat, historical photos into 3D Gaussian volumes, effectively "re-spatializing" the past. Custom code for batch processing and potentially 4D gaussian splatting creation. Marble (World Labs): Implementing Marble (World Labs) to generate synthetic 3D environments that reflects subjective imagination.
