Streamlines and Isosurfaces

Description:

This project was supposed to be an interactive representation of streamlines on an isosurface. I did not finish the streamline part of the project but did finish the isosurface portion. I placed n draggers on the scene who's location effects the density at each point. When the density values start to get higher than the given isovalue then the surface is created. I create my surface using the marching cubes algorithm. The program can be sluggish though because each density value must be calculated when the dragger is moved. Then add on top of that creating an isosurface.

Screen Shots:


Density almost completely
submerged within block

Density just
burshing block

Density completely submerged

First Dragger Submerged,
but not we drag another in

Now moved additional dragger
closer to center and changed view

Changed view from previous and
started moving top dragger
