A 3D scene editor implemented in C++ combined with OpenGL. It supports the functionalities of insert, tranlate, colorize, rotate, scale, animate, delete for triangle mesh objects in .OFF file format and it allows users to export scene into .svg files.

O: Start Translation mode.
P: Start Deletion mode.
U: Start Animation mode.
SPACE: Start/Stop the rotation of camera (by default the camera rotates arounf Y axis).
<, >: Change color for selected object.
/: Change projection (perspective or orthogonal)＜/br＞ [,]: change the shading method (vertex normal or face normal)
↑,↓,←,→: Move the camera on trackball up, down, left, right respectively by 2 degree.
+,-: Zoom in or out by 3%.
J,M: Rotate the selected Object by 2 degree clockwise or counter-clockwise around the Y axis.
H,N: Rotate the selected Object by 2 degree clockwise or counter-clockwise around the Z axis.
G,B: Rotate the selected Object by 2 degree clockwise or counter-clockwise around the X axis.
K,L: Scale the selected object up or down by 5% respectively.
W,S: Move the camera on Y axis.
E,D: Move the camera on X axis.
R,F: Move the camera on Z axis.
Z: Start the animation if the bezier curve for an object was constructed.
X: Take a screenshot and export scene to .svg file.
Q: Quit the program.
