3D Slideshow Transitions: Adding OpenGL-Accelerated Transitional Effects For Impress
0 likes727 views
The document outlines a project for Google Summer of Code focused on enhancing OpenGL features to create impressive 3D slide show transitions for OpenOffice. The author details their background in graphics programming and their collaborative efforts to develop a new OpenGL context for slide transitions, emphasizing the need for flexibility and user-friendliness. The presentation thanks mentors and encourages future creative contributions to improve software aesthetics.
3D Slideshow Transitions: Adding OpenGL-Accelerated Transitional Effects For Impress
- 2. 3D Slide Show Transitions Adding OpenGL-Accelerated Transitional Effects To Impress Google Summer of Code
- 3. Me DigiPen Institute of Technology, Redmond WA, USA Senior earning a Baccalaureate of Science Major in RTIS Minor in Physics Minor in Mathematics Experience: 2 Years Graphics Engines engineering for Video Games 3 Years OpenOffice.org User. (3 Years Starving Student) College and Experience
- 4. Project Overview Google Summer of Code '07 My Mentor: Project Leader: Thorsten Behrens WANTED: Student with extensive OpenGL experience. My Summer Employer
- 5. Acceptance “Hola” - Thorsten “Buenos Dias” - Radek Linux Cvs cws ./configure Dmake Build debug=true TDD
- 6. A Simple Plan A new OpenGL context would be created Compatible with the window and optimally close to the window and bitmap layout … ..then I would register the two bitmaps Mipmap them and store their OpenGL handle From there each frame would have an interpolated transition drawn on the screen. It all started with an Idea and an Assumption
- 7. First Draft How I Started I studied the Linux OpenGl tutorial (nehe.gamedev.net) Created a system demo Decided on implementation of the transition Gave massive amounts of freedom to the Transition creator.
- 8. Stupid
- 9. Rethinking it Scaling, Rotating, and Translating had to be guaranteed to be reversible with no effects. Knowledge of position or aspect ratio should never be required of the transition creator. The slide should always be facing forward when handed to the transition creator. Texture Coordinates should be determined only by the point on the slide. That didn’t work…so I tried something different
- 10. Much Better
- 11. Let's Make One! Let's make one I've never thought of, right now. Who's got a simple idea? OK, Start your watches.
- 12. RESULT! … .And now for the finished product
- 13. From Sandbox to Beach Lots of patience and help from my mentors and LXR I carefully worked my way through the puzzle How did I get out of my Demo and into OpenOffice.org?
- 14. My Future More creative power to the artists Create an import system More power to the programmers to allow for a cutting edge look Make The Redmond and Santa Clara based developers eat our Dust What I would add
- 15. Your Future So What do you want?
- 17. Thanks Thorsten Behrens Radek Doulík Google OpenOffice.org Community Sun Microsystems All of you for attending this Presentation
