How do I start using HARFANG 3D with Python?

Install the Python wheel from PyPI using 'pip install harfang', or build from source by enabling the HG_BUILD_HG_PYTHON CMake option. The Python module provides full API access for prototyping 3D applications quickly.

Is HARFANG 3D better than Unity for industrial simulations?

HARFANG 3D excels in embedded systems with multi-language support and cross-platform rendering via bgfx, while Unity offers a more user-friendly editor and larger asset store. Choose HARFANG for integration into existing C++/Python codebases, Unity for faster game development with pre-built tools.

Does HARFANG 3D work on mobile devices?

Yes, it supports ARM architectures and OpenGL ES, making it suitable for mobile platforms. However, deployment may require custom build configurations and testing for specific iOS or Android environments.

How to build HARFANG 3D from source on Windows?

Clone the repository with submodules, install Visual Studio 2019 and Autodesk FBX SDK, then use CMake with options like PYTHON_EXECUTABLE and HG_FBX_SDK, as outlined in the README's building section for a detailed step-by-step process.

Is HARFANG 3D free for commercial projects?

It is licensed under GPLv3/LGPLv3, which requires open-sourcing derivative works. For proprietary use, a commercial license must be purchased from the HARFANG3D website, adding potential costs.

What are the system requirements for running HARFANG 3D?

Requires CMake 3.19+, CPython 3.2+, and a compatible compiler like Visual Studio 2019 or GCC 9+. Graphics drivers supporting APIs like Vulkan or DirectX are needed, with specific dependencies listed in the prerequisites.

HARFANG 3D source code public repository

Use Cases

Best For

Building real-time 3D simulations for industrial or training purposes
Developing cross-platform VR/XR applications with OpenXR or OpenVR support
Creating embedded 3D visualization systems on Intel or ARM architectures
Prototyping 3D applications rapidly using Python or Lua scripting
Integrating 3D rendering into existing C++ or Go codebases
Developing applications requiring both low-spec and AAA-quality rendering pipelines

Not Ideal For

Teams wanting a drag-and-drop editor or extensive pre-built assets for rapid game development
Projects requiring stable Go bindings for production, as Go support is experimental
Small indie studios with limited time for complex C++ build configurations and dependency management
Open-source projects needing permissive licensing without commercial restrictions

Pros & Cons

Pros

Broad Language Support

Usable in C++, Python, Lua, and experimental Go, enabling flexible development from rapid scripting in Python to high-performance C++ integration, as highlighted in the multi-language features.

Extensive Cross-Platform Rendering

Built on bgfx, it supports Vulkan, Metal, DirectX, OpenGL, and OpenGL ES across Windows, Linux, Intel, and ARM architectures, ensuring wide hardware compatibility for embedded systems.

Dual Rendering Pipelines

Offers both low-spec PBR and high-spec AAA rendering with screen space GI, catering to various performance and quality needs for industrial or real-time applications.

Integrated VR and XR APIs

Supports OpenXR and OpenVR/SteamVR with tested compatibility for devices like HTC Vive and Oculus, facilitating VR development without additional libraries.

Cons

Complex Build Process

Requires CMake 3.19+, Autodesk FBX SDK, multiple compilers, and intricate configuration steps, making initial setup time-consuming and prone to errors, as detailed in the building prerequisites.

Limited Ecosystem and Community

As a niche library focused on industrial use, it lacks the extensive tutorials, assets, and third-party support found in mainstream engines like Unity or Unreal.

Restrictive Licensing Options

Licensed under GPLv3/LGPLv3, which may necessitate a commercial license for proprietary projects, adding legal overhead and potential costs beyond open-source alternatives.
