Detailed Description

Provieds methods for displaying a mesh with OpenGL.

For flexibility of use, Visualization does not set up an OpenGL environemnt or create any windows. It assumes that that has already been done, and simply accpets dimentions for the size of the window that as been allocated for it.

Visualizations have the ability to draw various elements of the mesh in many different styles, as well as a system to manage the progration of the mesh onto the windows, and to deal with zooming in/out.

Visualziations also can use the libpicio.so library to dump the screen to a image file.

Here is the call graph for this function:

void Visualization::project

(

)

Project the OpenGL environment onto the screen, accounting for zooming.

This function generates the correct projection of the mesh's coordinates system onto the screen. It takes into account wether the view is currently zoomed. When zoomed, the projection will maintain the overall aspect ratio of the unzoomed image. If the zoom window is not of the same ratio, it will change the width of the zoom window to correct the ratio.

Once the correct projection is determined the coordinates of that projecttion are stored in the view_top and view_bot variables.
