imgui-vtk

Incorporate VTK's dataset visualization capabilities with versatility of Dear ImGui
- Multiple independent VtkViewer instances can be used in the same program to display multiple VTK scenes simultaneously
Uses VTK's OpenGLRenderWindow class
- Renders to texture and displays the texture natively with ImGui
Compatible with both ImGui's main and docking branches

Usage:

imgui, gl3w, and glfw are included in this repository as git submodules
- For integration into an existing project, only VtkViewer.h and VtkViewer.cpp are needed. However, they will need to be linked with or built alongside Dear ImGui and VTK
Dependencies are built separately in CMakeLists.txt then linked together as static libraries
- CMakeLists-alt.txt builds everything together from source
Usage (see main.cpp for details)
- You must create and end ImGui windows yourself
  - Allows for other widgets to be placed in the same ImGui window as the VTK "viewport"
  - Allows for full control over window size, behavior, etc. via Dear ImGui API
Note: For the sake of cleanliness and readability, most ImGui preprocessor directives were removed. Files no longer auto-detect your OpenGL loader. While everything is currently set up for OpenGL3 + GLFW + GL3W, you may need to adjust #include statements, etc. to match your use case.
