This repository is the @playcanvas/supersplat-viewer npm package, an embeddable 3D Gaussian splatting viewer built on the PlayCanvas engine. It bootstraps a full web application around a PlayCanvas AppBase: createViewer(options) mounts a canvas and UI, loads .gsplat/.ply content plus optional skybox and voxel/mesh collision assets, and returns a ViewerHandle for capture, seeking, camera control, XR, and teardown. The default rendering path is the engine's sorted gsplat renderer; an opt-in WebGPU stochastic renderer provides unsorted splat projection, temporal anti-aliasing, occlusion culling, and depth-based picking. The repo is an application, not a data/research pipeline, though it contains research-grade rendering experiments and a dedicated benchmark harness.
This repository is the official collection of Godot Engine demo projects, maintained by the Godot Foundation. It contains hundreds of self-contained, runnable demo projects that showcase specific engine features across 2D, 3D, audio, GUI, networking, XR, mobile, compute shaders, and editor plugins. Each demo is a standalone Godot project with its own project.godot, scenes, scripts, and assets. The repository serves as both a learning resource for developers and a testbed for engine capabilities. While not a single application, it demonstrates a wide range of game development patterns and engine APIs. Notable highlights include a generic state machine implementation, a 2.5D node system, a virtual joystick for touch input, a custom logger with UI integration, and a JSON-driven dialogue system. The codebase is actively maintained with recent commits, low technical drift, and consistent use of modern Godot 4.x APIs.
This is an official Meta-published Unity sample repository demonstrating the Passthrough Camera API for Quest 3/3S headsets. It contains five distinct sample scenes: CameraViewer (live camera feed display), CameraToWorld (camera-space to world-space coordinate mapping with debug visualization), BrightnessEstimation (ambient light estimation from camera pixels), MultiObjectDetection (real-time object detection using YOLO via Unity Sentis, with 3D marker spawning), and ShaderSample (water shader using camera texture as reflection source). The architecture is a collection of independent scenes, each with its own manager MonoBehaviour and shared utility scripts (InputManager, DebugUIBuilder). The project targets Android via OpenXR and the Meta XR SDK (MRUK 85.0.0), with hand tracking and controller support. It is a learning resource, not a production application, but the code is well-structured with consistent conventions and several reusable patterns.
threeify is a TypeScript monorepo providing a WebGL2-based 3D rendering library with a focus on physically-based rendering (PBR), glTF support, and modular architecture. It is loosely derived from three.js but aims for a more modern, tree-shakeable design with native WebGL2 abstractions. The library includes a comprehensive math package (vectors, matrices, quaternions, colors, bounding volumes), a scene graph with cameras, lights, and materials (including clearcoat, sheen, transmission, and anisotropic extensions), a renderer with post-processing effects (tone mapping, Gaussian blur, bloom, cubemap background), a 2D layer compositor with blend modes and panorama support, and a custom GLSL-to-TypeScript transpiler for shader management. The codebase is organized into packages (core, math, scene, layer-compositor) and tools, with over 50 interactive examples demonstrating various rendering techniques. External dependencies include WebGL2 and browser APIs; the library is still in development and not yet recommended for production use.
