ProceduralTextureMaker generates texture images in arbitrary sizes based on graphs of nodes that take other nodes' output as input and transform them into new images.
Nodes are added dynamically and connected to each other graphically.
Custom UI widgets are created for each node based on the texture generator's user configurable settings, making it easy to try out new configurations and watch how changes affect the final output.
The project files with texture graphs can be saved to and loaded from XML files, and images can be exported to PNG files.
A number of texture generators written in C++ and Javascript are included with the project.
For more general information about procedural textures, see https://en.wikipedia.org/wiki/Procedural_texture
Two example textures have been added to the repository:
The application is written in C++ and uses the Qt framework.
It has been tested with Qt versions 5.9, 5.10, 5.12 and 5.15 on Mac OS, Ubuntu and Windows 10.
It uses multiple threads on multiple CPU cores where supported, so that CPU intensive texture calculations don't affect the UI performance.
It's easy to extend the application by adding new generators, especially ones written in Javacript as those are loaded dynamically from external files.
One example Javascript texture generator is included in the directory JavascriptTextureGenerators.
The external Javascript texture generators are parsed and run using the QtScript engine.
As the QtScript module is listed as deprecated and not installed by default by the Qt installer there is also support for running the scripts with the newer QJSEngine class.
QScriptEngine and not QJSEngine is still enabled by default as there were some strange unresolved bugs related to QJSEngine version 5.10's memory management encountered during development.
Changing which engine that should be used is done by adding or removing DEFINES += "USE_QJSENGINE" in ProceduralTextureMaker.pro.
Install and configure Qt 5.15, available at https://www.qt.io/download-open-source
If you're compiling with the QScript engine (see the Javascript section above) make sure that the Qt installation includes that module.
If Qt Creator was installed, use it to open and build the project file ProceduralTextureMaker.pro.
If Qt Creator isn't available, use a terminal to browse to the project root directory and run qmake && make && make install.
