Hello!

Thank you for inviting me to this opportunity! I will try my best to keep it short, though it might be a bit long for some. There's a TL;DR at the end, though. :)

A bit about myself. My name is Aaryaman Vasishta and I'm currently studying in my third year of Computer Engineering in Pune Institute of Computer Technology, India. My interests lie in game programming and computer graphics.

My project focuses on implementing the rendering backend for the D3DRM API [1].
D3DRM (Direct3D Retained Mode) is basically a scene graph API running on top of Direct3D's Immediate Mode API. You can say it's more like a rendering engine API which encapsulates Immediate Mode functionality in order to make it easier for programmers to develop 3D scenes using it, making it a possible competitor to OpenGL at the time.

At the moment wine's implementation of this API is mostly full of stubs, and there's quite a bit of work left before something can be drawn on the screen. My role here mainly focuses on implementing object Creation/Initialization functions for some of the main interfaces, mainly devices, textures and viewports, all of which are COM based. If time permits, I will also work on implementing some frequently used frames and lighting functions.

The API is quite old (it has been removed since DX 8 SDK, and the dll doesn't come included with vista onwards) but there are a few popular games that used it. Namely, Lego Rock Raiders and Steel Beasts, and applications as well, like FMS (Flying Model Simulator). So there is some merit in working on this. Implementing these functions will help accelerate further development of this API to get some long-awaited apps to run on wine (I can see quite a few threads on google of people trying to get FMS running, and a couple for LRR too, so there is some demand for it). As an added bonus, I also get to interact with wine's ddraw implementation for this one, which could potentially help ddraw's implementation via possible bug detection/fixes and implementing any ddraw functionality that d3drm requires.



TL;DR: I'm implementing a main chunk of a graphics API called Direct3D Retained Mode, which is based on Direct3D Immediate Mode. The API is mostly a stub in wine and this project should help get things going.

Thank you!
Aaryaman Vasishta

Hey all,

tomorrow the coding period of the Summer of Code begins and I though
it might be a nice idea to let the community know about the projects
we've got this year. Actually, I though it would be even better if the
student themselves wrote a short summary of their own project for the
mailing list.

So, with no authority backing me, I'm kindly asking that. No need to
write anything too fancy, just a few lines explaining what are you
going to work on over the summer and maybe what are the expected
benefits for Wine.

Thank you!
Matteo.
