Prisma Engine is a cross-platform 3D game engine built with modern C++20, designed for developers who want high-performance rendering and clean architecture without sacrificing portability. These docs cover everything from setting up an SDK-based project to building the engine from source, working with the Entity Component System, integrating audio, and targeting Windows, Linux, and Android platforms.

​
Key features

Vulkan and DirectX 12 rendering

Hardware-accelerated GPU rendering with forward and deferred pipelines, HLSL and GLSL shader support, and Vulkan Memory Allocator integration.

Entity Component System

A high-performance ECS built on Prisma::Core::ECS::World with typed component pools, system scheduling, and per-frame timestep updates.

SDL3 audio

Cross-platform audio via the SDL3 backend with 3D spatial sound support. Pluggable driver interface supports platform-native backends where available.

Integrated ImGui editor

Built-in editor tools for scene inspection, component debugging, and runtime overlays. Enabled automatically on debug builds via PRISMA_ENABLE_IMGUI_DEBUG.

Cross-platform support

Targets Windows x64, Linux x64/ARM64, and Android arm64-v8a. CMake presets cover all platform and build-type combinations out of the box.

Asset management

Thread-safe asset loading with JSON and Base64+zstd binary serialization. Supports textures, meshes, tilemaps, and cubemaps via a unified AssetManager.

​
Module status

The engine is under active development. The table below shows the current completion level for each core module. Overall project completion: ~70%
The Windows Vulkan backend is production-ready with a fully integrated ImGui editor. The prune branch focuses exclusively on the SDL3 + Vulkan rendering path. DirectX 12, XAudio2, and OpenGL backends are removed on this branch.
