Rendering and Gameplay – The Pure Renderer September 23, 2010

Posted by luciusdxl in Uncategorized.

So I’ve been taking some time to get myself up to speed about where I was in the project. One of the issues I was still looking at was were annoying sector/portal corner cases that seem to come up all too often with Dark Forces geometry. The renderer updates I was working on will solve those issues once I work out some kinks and the proper perspective renderer will be made available to fix these. However, what’s more important is getting the game fully playable and continuing to work on these issues is slowing it down – especially with limited time. So what I’ve decided to do is get the “pure renderer” at least partially in, so that these issues can be avoided for now and the gameplay / user level support can be finished.

The “pure renderer” uses a straight forward perspective view with off center projection when looking up and down – basically this means it’ll look a lot like the hardware accelerated Outlaws (except without all the texture issues, color depth issues, lighting anomalies and so on). You’ll still get filtering, mipmapping, optional anti-aliasing, anisotropic filtering, alpha blending, optional bloom, optional dynamic lights and all the other elements of the current renderer, but with the skewed look up and down. And yes, mouse look will still work just fine, but with a more limited pitch range. What does this buy us? Exact portal traversal with simple 2D clipping. That means that all the overlapping sector and weird portal tricks will work without the corner cases that are problematic for the current renderer. This way I can finish everything else and not worry about the current perspective portal renderer – it can wait and be revived at a later date. This will allow every level to look correct with no more fancy tricks and numerical clipping issues.

So once the pure renderer is finished, I’ll release a build and be able to focus on gameplay – and finally get this thing moving!
