Title: Help wanted Post by: David Makin on September 23, 2009, 09:44:34 PM Hi all, can anyone either send me or point me at somewhere to download a complete VS2005 project for rendering a fractal (e.g. standard Mandy or Julia) using GPU shading vertex/fragment code with OpenGL ?
Edit: Just to add that I found this: http://nuclear.sdf-eu.org/articles/sdr_fract/ (http://nuclear.sdf-eu.org/articles/sdr_fract/) but haven't the slightest idea of how to set up an OpenGL based project in VS2005 to impliment the routine and MS documentation stinks (I had no trouble whatsoever doing a version for the iPhone 3+ simulator in Xcode).

Nevermind, I just looked at this: http://www.opengles-book.com/downloads.html (http://www.opengles-book.com/downloads.html) and I think I'll just wait until I have a Mac at home :) Title: Re: Help wanted Post by: lycium on September 23, 2009, 11:44:04 PM [edited to remove non-working link]

Title: Re: Help wanted Post by: David Makin on September 24, 2009, 02:06:06 AM Found this one using Direct3D:
http://files.myopera.com/nerius/files/GpuFractals.zip (http://files.myopera.com/nerius/files/GpuFractals.zip) And created a VS2005 solution but I only have an X600 card so it needs to be redone for shader 2 instead of 3. My knowledge of shader code is limited - can someone convert the relevant shader/direct3d code to shader 2 ? (Note that I just need a single working looping version i.e. having 4 versions, 2 with unrolling is irrelevant). Also does it actually work on cards supporting shader 3 ? (All I get is a black screen, direct3D doesn't even report an error when compiling the shader code though it does hang for a long time when doing so) Title: Re: Help wanted Post by: David Makin on September 24, 2009, 02:12:11 AM lemme try that again: http://www.cs.caltech.edu/~keenan/project_qjulia.html Thanks - will definitely try that when I get around to installing my ATI X1900XT (I need to get a new PSU first). At the moment I just have an X600 so I need shader 2 code rather than shader 3, I'm presuming it's possible to do a Mandy or Julia using shader 2 since it can be done for OpenGL ES 2 on the iPhone, or is that shader 3 ?
