Node-based Image Editor

---

Cascade is a node-based image editor with GPU-acceleration.

Features

• Non-destructive node-based editing workflow
• All image processing is done on the GPU
• 32 bit linear color pipeline
• Support for the most common color spaces and file formats

Download

Cascade is free software. If you want to try it out, the latest binaries for Windows and a Linux AppImage are here.

If you want to get involved or have questions, please join our Discord or create an issue here on Github.

Windows Build

To build the project on Windows, you will have to install Qt and the Vulkan SDK manually. The rest is handled by vcpkg.

Windows versions are compiled with MSVC 2019 64bit.

Install Qt using the official installer. At the moment we are using version 5.15.0, installed into C:\Qt515.

It's easiest to use Qt Creator as IDE, but feel free to use Visual Studio if you want.

Open a command prompt and clone the Cascade repo:

git clone https://github.com/ttddee/Cascade

Enter the project directory and install vcpkg:

cd Cascade

git clone https://github.com/microsoft/vcpkg

.\vcpkg\bootstrap-vcpkg.bat

Now you can install all other dependencies using the command below:

.\vcpkg\vcpkg --feature-flags="versions" install --triplet=x64-windows

It will take a while to compile but upon completion you should be able to open the project in Qt Creator, configure your compiler and build.

Ubuntu Build (21.10)

We are going to download the repository into the home directory.

cd ~

Clone the repository:

git clone https://github.com/ttddee/Cascade

Change to the Cascade directory and execute the ubuntu-setup bash script.

cd Cascade

chmod +x ubuntu-setup

sudo ./ubuntu-setup

This should install all the dependencies you need as well as QtCreator.

Now, open the project with QtCreator and configure it to use Qt5, GCC as compiler and GDB as debugger.

Shortcuts

• F1 - View selected node front input

• F2 - View selected node back input

• F3 - View selected node alpha input

• F4 - Toggle between selected node RGB output and alpha output

• Delete - Delete selected node

• Ctrl + Left Click - Reset slider to default

Tech

Cascade is written in C++ and runs on Windows and Linux. You will need a Vulkan-compatible GPU to run the program.

The GUI was created in Qt and all rendering is done on the GPU through Vulkan with GLSL as shading language.

For IO and color space conversion we are using OpenImageIO/OpenColorIO.

Multithreaded computations on the CPU are done with TBB.
