Easy to use modern 3D graphics rendering abstraction API and cross-platform application framework:

• Builds on top of modern native 3D graphics APIs: DirectX 12 on Windows, Vulkan on Linux, Metal on MacOS, iOS & tvOS.
• Simplifies modern graphics programming with object-oriented medium-level graphics API inspired by simplicity of Apple Metal. Common shaders code in HLSL 6 is used on all platforms.
• Provides cross-platform application framework with CMake build toolchain, platform-independent application foundation classes and native-GUI layer for Windows, Linux and MacOS.

Download release builds with pre-built samples, tutorials and tests to try them out. Check latest build status, tests, code coverage and analysis results or get build artifacts from GitHub Actions CI and Sonar Cloud. See Build Instructions topic for manual build instructions and start learning Methane Graphics RHI API with Hello Triangle and other tutorials' documentation.

Methane Kit architecture is clearly distributing library modules between 5 layers from low to high level of abstraction.

Methane Graphics RHI module implements a set of public object-oriented interfaces, which make modern graphics programming easy and convenient in a platform and API independent way.

Start learning Methane Graphics API with Hello Triangle tutorial documentation and continue with others.

Name / Link	Screenshot	Description
1. Hello Triangle		Colored triangle rendering in 100 lines of code.
2. Hello Cube		Colored cube rendering in 200 lines of code with vertex and index buffers.
3. Textured Cube		Textured cube introduces buffers, textures and samplers usage with Phong shading.
4. Shadow Cube		Shadow cube introduces multi-pass rendering with render passes.
5. Typography		Typography demonstrates animated text rendering with dynamic font atlas updates using Methane UI.
6. Cube-Map Array		Cube-map array texturing along with sky-box rendering.
7. Parallel Rendering		Parallel rendering of the textured cube instances to the single render pass.
8. Console Compute		Conway's Game of Life implemented in Compute Shader and running in pure console application.

Methane samples demonstrate advanced techniques and usage scenarios with more complex implementation than tutorials above. Samples are distributes in form of separate repositories.
