Fractal Architect Render Engine

Open Source, Portable Flame Fractal GPU Rendering Engine


Why?

Filling a deep need for extremely fast GPU rendering and high quality output to the Flame fractal community.

Your favorite app can now support GPU rendering.

What is It?

Packaged as a dynamic linked library, so it can be embedded in commercial or open source flame fractal editors like Apophysis, JWildfire, Chaotica.

Portable

Written using portable C++ 14. Portable rewrite of commercial Fractal Architect app's render engine.

FA 5 is a commercial Apple Mac app.

Supported Platforms: Windows, Linux, MacOS

JWildfire

Jwildfire 3.0 uses this render engine for GPU accelerated rendering.

Windows 10
  • Tested on Windows 10 using Nvidia, AMD, and Intel GPUs
  • OpenCL/CUDA platform GPU rendering. Multiple GPU rendering.
  • Great performance.
  • Choice of OpenCL or CUDA (Nvidia GPUs) rendering mode.
Mac OS - Mavericks thru Sierra
  • Same performance as FA 4 app.
  • Dependent on Apple's OpenCL drivers, so Intel GPUs not supported on Mac OS El Capitan, but does work on Mac OS Sierra
  • CUDA rendering on Nvidia GPUs.

New Features in the Works

  • Linux Support
  • Support for new Jwildfire features

For Developers

3rd Party Dependencies
  • Library itself has no 3rd party library dependencies. It is completely standalone.
    • Exception: OpenSSL on Mac OS
  • Unit Testing framework: uses CXXTest Unit Test Framework
  • Example app uses GraphicsMagick API to save images to file.
Build Instructions

See BuildingNotes.txt for complete instructions.

GraphicsMagick is a pain to build as its such a big API. The library itself does not use GraphicsMagick, it is only used by the example app.

So that means that you can use a different imaging API, like .Net, Cocoa, or Java. There are only about 5 lines of code in the example app, that would need to be replaced.
