3D Viewer (QT + OpenGL + C)

Overview

Load a wireframe model from a file of the [about] format (support only for a list of vertices and surfaces)
Move the model by a specified distance relative to the X, Y, Z axes
Rotate the model by a given angle relative to its axes X, Y, Z
Scale the model by a given value.
Adjust the projection type (parallel and central)
Customize the type (solid, dotted), the color and thickness of the edges, the display method (missing, circle, square), color and size of vertices
Choose a background color
Save settings between program restarts
Save the received ("rendered") images to BMP and JPEG
Use a special button to record small "screencasts" - current user affine transformations of the loaded object into gif-animation (640x480, 10fps, 5s)
