Summary :
In this program, the user can construct and animate scenes using vector graphics and frame tweening. The scene graph is held in a node tree data structure where each node holds a vector graphic polygon and pointers to its sub-nodes. Animations are stored as a series of key frames where transforms have been applied to nodes. During playback, intermediate frames are linearly interpolated between key frames allowing a smooth transition of position, translation, rotation, scale, and color.
Demo Instructions :
- To run the demo, you must have the Microsoft Visual C++ Redistributable for Visual Studio 2017 installed.
- Download the "Vector Graphics Animator - Demo.exe" file and the "Animations" folder from this project.
- Run the Demo.exe.
Libraries & Technologies Used :
- FLTK - Fast Light Toolkit is a cross-platform C++ GUI toolkit.
