Current status

Spkgen is in developpement and is not yet fully functional.
Development is done on linux.
Building on another system is not tested but final release should be cross-platform.

Features

• C++ and Qt based interface.
• Spkgen internally use Urho3D for rendering particles.
• and Urhox library to bind the SPARK particle engine to Urho3D.
• node core system is provided by the external qt nodeeditor library.

TODO

• implement generic nodes classes
• automatic node's parameters widgets creation from simple declaration
• show 3D debug zones geometries
• serialize node widget's parameters
• graph plot editor widget for spark graph interpolators
• complete all spark nodes
• interact with 3D view (camera move...)
• multiple scenes managment
• comments items on node view
• set styles
• add shortcuts on node view : copy/paste/cut nodes
• add samples and tutorials (WIP)

Build

Spkgen developpement is done with Qt 5.11.1 + QtCharts module for tgraph plot editor widget.
WARNING : Do not use Qt 5.11.2, I experienced some bugs with FileDialogs on linux...

1. Get submodules

git submodule init
git submodule update

2. Build the external nodeeditor Qt library

cd 3rdparty/nodeeditor
mkdir BUILD
cd BUILD
make

3. Set URHO3D_HOME and URHOX_HOME variable path in QtCreator :

(Urho3D and Urhox libraries need to be builded)

- Open spkgen.pro with QtCreator.
- Edit spkgen.pro file
- Set variable path :

#--------------------------------------------------------------------
# path to Urho3D and Urhox
#--------------------------------------------------------------------
URHO3D_HOME = /home/John/Dev/Urho3D/BUILD
URHOX_HOME = /home/John/Dev/Urhox/output

4. Build

- Copy Urho3D assets 'Data' and 'CoreData' to Spkgen/Bin
- Open Spkgen.pro with QtCreator
- Build and Run
