d3d three more renderstates for n2002
Hi! with one of the last patches from the cvs the game Nascar 2002 now recognizes the d3d rasterizer in the config tool. The patch below adds three more handlers for the D3DRENDERSTATE. As d3d seems to me pretty undocumented i can only try to find things out using goolgle and see the example code there - a link to doku would be really appreciated. Only the D3DRENDERSTATE_CLIPPING stuff seems pretty obvious. I dont have a clue what the EXTEND stuff does and can also only guess what the EDGEANTIALIAS does. I also was not able to test it in the game - the d3d stuff seem to lack a lot of functions this game relies on - i will try to add further functions step by step. The d3d7 code looks pretty bound to mesa - i dont use mesa, so i can not say if this works or not with mesa - only with the opengl provided by nvidia and what the manpages say. RFC and CU!

For the documentation, do a Google search on the .CHM files from the various DirectX SDKs (as the relevant documentations are not to be found anymore on MSDN's site, only DX8 / 9 is still there). I have them all but think it's not very legal to redistribute them. I could though give you the file names so you can Google them :-)
Only the D3DRENDERSTATE_CLIPPING stuff seems pretty obvious. I dont have a clue what the EXTEND stuff does and can also only guess what the EDGEANTIALIAS does. I also was not able to test it in the game - the d3d stuff seem to lack a lot of functions this game relies on - i will try to add further functions step by step.
Well, I really wonder what 'the lot of functions' are that is lacking... Do you have a tree with all the patches recently sent applied to or a plain CVS tree ? From my experience, the only stuff missing is the SetTextureStageState stuff. I doubt that other 'important' features are still missing.
The d3d7 code looks pretty bound to mesa - i dont use mesa, so i can not say if this works or not with mesa - only with the opengl provided by nvidia and what the manpages say.
Well, the Mesa name in the Wine source tree is historic (at the time these files were created, the only OpenGL code for Linux was Mesa and it was using the OSMesa extension to run). And as it's a pain to rename files in CVS, it was never done. The day we will move the files around to a d3dgl.dll library to ease packaging, the files will be renamed.

Well, did you add also the code creating these clipping planes ? Otherwise, it's not such a good idea to enable them :-) I will have to reboot in Windows (or pester Endy to give me his CHM file viewer :-) ) to tell exactly what that should do and how these clipping planes are created.
+ + case D3DRENDERSTATE_EXTENTS: + /* boolean + * dont have a clue what this does */ + FIXME("What is D3DRENDERSTATE_EXTENTS supposed to do?\n"); + break;
Why not keep the standard 'not supported' instead of adding a case ?
+ + case D3DRENDERSTATE_EDGEANTIALIAS: + /* in opengl the antialiasing of points, lines and polygons can + * be set separate - assuming this only actives it for polygons */ + if (dwRenderState) { + glEnable(GL_POLYGON_SMOOTH); + } else { + glDisable(GL_POLYGON_SMOOTH); + } + break; +
This looks fine... Except that I have no real idea after reading the OpenGL man page exactly what GL_POLYGON_SMOOTH does :-) And I think you could enable it for lines too (but well, I do not know any game using lines though). Anyway, welcome on board :-) Lionel PS: I updated the d3d_status.html page. -- Lionel Ulmer - http://www.bbrox.org/

Im not sure if your refering to the online documentation (if you are then your right), but at least the dx7a sdk is still availible from: http://download.microsoft.com/download/win98SE/DXSDK/7.0a/W9X/EN-US/dx7adxf.... nog.
