My Idea for GSOC
by Daniel Oom 09 Mar '12

09 Mar '12

Hello, my name is Daniel Oom and I'm a computer science and engineering student at Chalmers in Gothenburg, Sweden. I'm in my second year and I would love to partake in GSOC. I know C, use Linux daily and don't like it when I have to reboot my computer to windows. I am very interested in game development and real time rendering, and have actually completed one simple game (written in Java/OpenGL). But I still have so much left to learn, and I believe I can learn a lot through working with wine in these areas. My idea, or rather how I would like to improve wine, is related to gaming. I've tried to run some games in wine and sometimes it works very well but more often than not there's bugs. The bad performance, misc bugs and general unresponsiveness of Steam is my greatest itch. Though as I'm not versed in wine's code base I don't know what would constitute as reasonable goals for GSOC. (I did do a bug report a long time ago, but back then I did not know a lot about programming). Would, for example: fix Steam's in-game overlay feature be a good goal? Some advice about where to take it from here would be greatly appreciated. // Daniel Oom

Re: [PATCH 1/5] wined3d: Clamp fog coordinate in the vertex shader.

The tests do not answer this question because they write the same fog coordinate for each vertex. Imagine for example two lines. In each of those lines, one vertex has oFog = 0.0. The other vertex has oFog = 1.1 in one line, and oFog = 100 in the other. If the value is clamped per vertex, those lines will look the same. If it's clamped per pixel, the latter line will have much steeper gradient Also, what happens to shaders that do not write oFog, but use oPos.z, especially in the situations where the near and far clipping planes are disabled?

Re: [PATCH 4/5] wined3d: Remove a texture dimension check in state_alpha().

Alexandre: The patch is OK, this mail is just some random note on why the code was there in the first place. Am Donnerstag, 8. März 2012, 20:27:15 schrieb Henri Verbeet: > I don't think there's any reason color-keying shouldn't work on e.g. cube > textures, although it probably isn't very common either. Fyi, I believe the original reason for this check was this line of code, removed by commit 70ed814b95f7719d52fa5b18a375d566a185a9ec. surf = (IWineD3DSurfaceImpl *) ((IWineD3DTextureImpl *)stateblock- >textures[0])->surfaces[0]; The implication for the current code is that there should be tests for color keying with mipmaps and cubemaps. Cubemaps are unlikely to be used with color keying as you say, and writing tests for mipmapping is on my todo list for proper color keying with the ffp replacement shader and blit shaders once I have time for this.

Building the 1.6 Release Notes as things are written.
by Scott Ritchie 08 Mar '12

08 Mar '12

So, congrats everyone, 1.4 is out and I'm very happy about it :) I wanted to thank Alexandre for his release announcement, it was very through and informative. It also looked like a lot of work. This made me wonder if we could instead build up the announcement gradually with some sort of process. For instance, if every significant feature added to a development release were put onto a wiki page, then at any point in time we could point someone there to answer a general "what does 1.5 have over 1.4?" question. Come 1.6 release time, we could just copy and edit the page as the official announcement. Thoughts? -Scott Ritchie

Re: [RESEND] [PATCH] winepulse: Add pulseaudio driver, v9
by Stefan Dösinger 08 Mar '12

08 Mar '12

Hi Maarten, >From a technical point of view, two things popped out: 1) configure is autogenerated by Alexandre, so you shouldn't include it in your patch. configure.ac is enough. 2) The patch doesn't apply with git-am. I don't know how much of an issue this is for AJ, but I prefer git-am over git-apply and manually committing I barely know too much about sound, so I'm leaving the rest of the tech stuff up to Joerg and Eikum. >From a user point of view, I have a previous version of that driver in my tree, and great hopes that it fixes some issues on my gaming setup that uses Pulseaudio(due to a multiseat configuration), e.g. bug 28856. The alsa route may eventually fix those bugs too, but I'm hoping for that since more than a year. So good luck with your Pulse driver, and thanks for working on this flamewar- infested stuff.
