Render Engine - First Principles 🧊

3D Gaussian Splatting through Render Engine - First Principles ✨

With the latest advancements in Computer Graphics, there is a new Pandora's box that has been opened called - '3D Gaussian Splatting'. It works on the concept that real world scenes could be efficiently represented as 3D Gaussian Splats (3DGS) - as an alternative to Traditional Mesh representation which involves - Mesh, Textures, Lighting etc.

This 3DGS representation has the primary advantage that huge real-world scenes which are otherwise generated by classic photogrammetry & complex to render using traditional computer graphics techniques can now be represented as 3D Gaussian Splats, which you can imagine as 3D paint strokes with a centered color and transparency values around the center, which also takes into account from where/how the scene is being viewed (aka the Camera). When multiple of these strokes are rendered with proper blending of alpha transparency from each splat, it can form a near realistic 3D image that can be viewed from any angle. 🔮

Get Started 📺

Clone Repo

Use git clone <repo-link> to clone the repo to your PC

Install the Packages

Use npm i to install the necessary packages

Run the 3D Viewer

Use npm run dev to run the viewer in development mode

Viewer

Now you can see the Render Engine running on http://localhost:5173. You can navigate, interact & play around with the 3D Assets!
