1. GORT GL Object Rendering and Transformation Leon Kania – Haipin Cua – Chang Huang – Thoren McDole

2. Outline  Description  Features  Applications  Goals  Challenges

3. Description  A professional-level design and a virtual GL modeling environment for the various needs of computer programmers. –Chemistry –Physics –Engineering –Mathematics –Medical –Animation/Game Development –Robotics

4. Features.  Creating complex objects through the composition of simple primitives. –Spheres –Cones –Cubes  Each primitive has a level of complexity which progressively adds to the preceding level’s capabilities.

5. .Features  Ability to output compile-able C code which can be used as an educational tool or a stand alone graphics format.  First person object manipulation. –Tweak parameters visually.  Texture Maps  Materials  Positions  Environment Effects –Lighting, Fog, etc.

6. Applications……  Chemistry –3D Molecule Visualizations. –Influencing grant proposals with the use of visually appealing display of 3D Molecules. –Hands-on approach to visualizing molecule interaction.

7. .Applications…..  Physics –Visualizing fields  Magnetic, Electric, etc. –Modeling Plasmas  Applicable to UNR Physics Department. –Astronomy  Planetary Motions.

8. ..Applications….  Engineering –Visualization of structures.  Buildings  Bridges  Towers –Visualization of physical systems.  Gear Trains  Engines

9. …Applications…  Mathematics –Fractals –Topology –Function Graphing –Direction Fields

10. ….Applications..  Medical –Modeling of body parts. –Visualization of blood flow. –Modeling and demonstration of medical technologies.

11. …..Applications.  Animation/Game Development –Figure modeling –Time framing –Environment Modeling

12. ……Applications  Robotics: GORT –Illustrates physical modeling capabilities of program.  Position objects in space  Set environmental parameters  Set object parameters –Simple interaction between objects  Objects are modeled according to a hierarchical relationship. –Basis for more complicated physical interactions.  Each object’s position is a function of another object’s position. –As in marionette

13. Goals  Basic GUI functionality  Implement basic program functionality with basic primitives  Expand functionality to include more complex primitives. –Splines, Bezier Curves, NURBS, etc.  Output compile-able C code.  Walking GORT, take me to your leader.

14. Challenges  Coordinating our efforts  GUI design  Learning Advanced features of Open GL API  Learning underlying theory and math behind computer graphics  Learning the GTK windowing API  IMPLEMENTATION
