Graphics Tools Framework A Framework to create C/C++ desktop tools oriented to 2D/3D graphics manipulation. This project started as an extraction of reusable code from the TexPainter project. The idea is to implement a feature-rich library to empower tools like TexPainter and others with similar needs.

• Multiple windows with shared OpenGL 3 context on Windows and MacOSX
• Abstract render hardware interface
• 2D Texture resource & loader (PNG, TGA, JPEG and HDR)
• 3D Mesh resource & loader (OBJ and FBX)
• ImGui integration with additional widgets
• Template class collection for custom node graphs

• Texture writer (PNG, TGA, HDR)
• Save/Load dialogs helper
• A docking system based on the LumixEngine implementation
• Improved node graph system

• API Design, some decisions I made are not the best ones
• Replacing GLFW with something that let us use DirectX in the future
• Replacing tinyfielddialogs, while it is a very useful library I prefer a more native-os-api approach
• Experience with bgfx to discuss about it's integration here instead of the current render hardware interface

• GLFW - OpenGL windows
• ImGui - Grahic user interface
• glm - maths
• Autodesk FBX - FBX mesh loading
• tiny_obj_loader - OBJ mesh loading
• stb headers - texture loading/write, text utilites, etc...
• glad - OpenGL functions loader
• khrplatform - khronos types
• mikktspace - Synched normals
• tinyfielddialogs - load/save dialogs

** 31 Jul 2016 **

• Texture2D resource with loader (JPEG, PNG, TGA, HDR)
• Improved 3D Mesh viewer example with textures (color and normal map)

** 30 Jul 2016 **

• You can now build GTF with CMAKE in Windows and OSX
• RHI Refactor (removed shared_ptr usage, added configurable vertex attribute list for VAOs)
• Implemented mesh loading (OBJ and FBX)
• Added 3D Mesh viewer Example
