IFSRenderer started as a weekend project to help me understand how the fractal flame algorithm works. My initial goal was to just implement it in 3D, but it has grown into a passion project and then into my master's thesis. I'm releasing it as an open-source project in the hope that it will be useful to the fractal artist community.
- Render 3D IFS (Iterated Function System) fractals
- Real-time interaction
- Node-based editor
- Mutation-style generator
- Extendable with Plug-Ins
- Animations
- Fisheye projection, ideal for planetarium dome masters
Planned:
- Gradient editor
- Animation curve editor
- More intuitive coloring methods
- Add Your Ideas
- Windows 10 or later
- OpenGL 4.5 capable graphics card

Previous versions can be found on the Releases tab.
You may build the project yourself using Visual Studio 2022 (with .NET Desktop Development workload).
Since the default transforms are hosted in a separate repo, use the --recurse-submodules switch when cloning:
git clone --recurse-submodules https://github.com/bezo97/IFSRenderer.git
The Setup project uses a VS extension, which is not required to build the portable IFSRenderer executable. You can ignore the "unsupported" warning and keep the Setup project unloaded.
Please follow the .editorconfig file in the root of the repository. If you submit a pr it must have the right formatting, otherwise the PR fails. You can fix the formatting by using the cleanup found in Visual Studio / Visual Studio Code / Rider, which will respect the editorconfig.
To fix the formatting through the CLI run the following in the root of the project:
# You only need to restore the first time, or when the tools change
dotnet tool restore
dotnet dotnet-formatBeginners should start with the Getting Started Guide. See the Wiki for more.
Add the latest NuGet package to your project. Here are some getting-started snippets.

Generate a random fractal:
//Initialize
using RendererGL renderer = new(graphicsContext);
renderer.Initialize(loadedTransforms);
Generator generator = new(loadedTransforms);
//Generate fractal
IFS fractal = generator.GenerateOne(new GeneratorOptions{ });
fractal.ImageResolution = new Size(1920, 1080);
//Render
renderer.LoadParams(fractal);
renderer.DispatchCompute();
renderer.RenderImage();
//Save HDR image
var histogramData = await renderer.ReadHistogramData();
using var fstream = File.Create(path);
OpenEXR.WriteStream(fstream, histogramData);Modify a fractal programmatically:
//Load from file
IFS myFractal1 = IfsSerializer.LoadJson("myFractal1.ifsjson", loadedTransforms, true);
//Change params
Iterator selected = myFractal1.Iterators.First(i => i.Opacity == 0);
Iterator duplicated = myFractal1.DuplicateIterator(selected);
duplicated.Opacity = 1;
duplicated.TransformVariables["Strength"] = 10.0;
//Save to file
IfsSerializer.SaveJson(myFractal1, "myFractal1.ifsjson");Render images:
for (double i = 0.0; i <= 1.0; i += 0.1)
{
selectedIterator.TransformVariables["weight"] = i;
renderer.InvalidateParams();
renderer.DispatchCompute();
renderer.RenderImage();
var image = await renderer.ReadPixelData();
myRenderedImages.Add(image);
}Alternatively, image data can be written directly to a bitmap:
await renderer.CopyPixelDataToBitmap(myBitmapPtr);- Browse the Wiki pages
