    Graphic Engine Architecture

    I'm looking for technical architecture specifications of 3D graphic Engine supporting OpenGL. My question is: how can a designer contribute to accelerate graphic processing without speeding-up a CPU?

    Re: Graphic Engine Architecture

    in the term designer , i understand that you make models for any games.
    So, maybe you can optimize your models by supressing some trianlges. And try to make them as strip or fan triangles (most of time, it depends of your modeler).

    i hope i answer

    Re: Graphic Engine Architecture

    JD,
    I said designer in term of IC design. I mean which information I need to optimize the architecture of all the processing elements I put into my 3D engine to speed up the application (games, modelling, etc).
    I'm looking for detailed hardware specs. How each GL function is processed, pipelined, parallelized, etc.

    Re: Graphic Engine Architecture

    Maybe, before entering OpengGL hardware specification and implementation, you should get informations on visibility determinations like occlusion culling or view frustum culling, z-sorting via octrees Kd-trees and bsp/portals, LOD, VIPM, ...
    But maybe you already know all that, but maybe not.

    Hope this helps

    Charles Bloom has some good stuff... http://www.cbloom.com/3d/

    John Ratcliff gave a very good talk at GDC which is available online... http://jratcliff.flipcode.com/
    See SPEECH.DOC

    and surprisingly enough Delphi 3D has some good stuff... http://www.delphi3d.net/articles.php
    See the stuff at the bottom

    I think you should have a look on the Titan 3D engine source code which can be donwloaded form http://talika.fie.us.es/~titan/titan/rnews.html.

    This engine can render Quake III maps at 95% of the original Quake III.
    It contains optimized render code.

    Re: Graphic Engine Architecture

    This is a broad subject with many topics, get this book, it covers a lot of material on the stuff you are asking about.

    Re: Graphic Engine Architecture

    Hmm... rereading the thread, you're talking about hardware design information, this is an unusual question, the book I mentoned is mainly for software designers........

    How about this course:
    http://graphics.stanford.edu/courses/cs448a-01-fall/

    This page has some interesting related reading:
    http://graphics.stanford.edu/courses.../readings.html

    There's some interesting material on both of these pages for you.

    I think there's maybe some confusion on this, Software optimization for graphics hardware doesn't delve too deeply into the hardware details, it's more to do with ballancing the pipeline load, measuring what you can, and chosing the fastest path (set of opengl state) and dispatch suitable for your application.

    I still think it's the book you need.

    Re: Graphic Engine Architecture

    Guys, to reply to all of you will take hours. Let me time to read and study all the tips you gave me. Anyone of you is now working of GPU architecture ? Maybe we can have a closer discussion outside the forum ... uhm ... do you think a new discussion forum on this topic could be setup ? DD

    Perhaps you should clarify what you want to discuss.
