WebEngine

Next-generation web engine. Written in C++. Uses the WebGPU rendering API, with native support for Windows, Linux, and macOS, as well as all WebGPU-compatible browsers including Safari (iOS) and Chrome (Android)

Tech Stack

• Flecs - High-performance Entity Component System (ECS)
• Jolt Physics - Physics engine for collision detection and rigid body simulation
• Ozz Animation - Skeletal animation and skinning
• Assimp - Asset importer supporting 40+ file formats
• ImGui - Immediate mode GUI for debug tooling
• Emscripten - C++ to WebAssembly compiler toolchain
• Tracy - A real time, nanosecond resolution, remote telemetry, hybrid frame and sampling profiler
• CodeChecker - Static analysis tool built on LLVM/Clang Static Analyzer toolchain

Rendering

Built on WebGPU, running natively via Dawn (Vulkan, Metal, DX12) and in all modern browsers via Emscripten/WebAssembly

• Physically based forward rendering with Cook-Torrance BRDF — GGX normal distribution, Smith geometry, and Schlick Fresnel
• Image-Based Lighting (IBL) — irradiance and pre-filtered specular maps computed via compute shaders
• Instanced draw calls batched by mesh/material; transforms stored as a compact 3×vec4 and reconstructed on the GPU
• Shader reflection — parses WGSL and generates reflection info for WGSL shaders
• Dynamic bindings via BindingManager — binding layouts are dynamically generated from reflection info by name, with per-resource invalidation and validation
• Cascaded shadow maps with per-frame recomputed splits based on the camera frustum
• GPU mipmap generation via compute shaders at load time for 2D textures and cubemaps
• GPU skeletal animation — bone matrices in a storage buffer, 4-weight per-vertex blending in the vertex shader; animation runtime via Ozz-Animation
• Dynamic material uniforms — scalar and vector properties set by name, offsets resolved via shader reflection and written directly into the GPU uniform buffer
• Modular render pass — each pass independently declares its framebuffer, bind groups, and pipeline, with live shader hot-reload
• Draco & KTX2 Support — supports draco compressed vertex format and KTX supercompressed textures

Building the engine

For Linux check ./setup_deps.sh and windows ./setup_deps.ps1.
