It allows you to generate multiple techniques for all your materials from a set of high-level per-material properties. РІР‚вЂњ High-level layer on top of OGREРІР‚в„ўs material system. But thatРІР‚в„ўs not all, hereРІР‚в„ўs scrawl detailing the new libraryРІР‚в„ўs design and features: From now on we can write a shader once and then compile it as either GLSL or HLSL. To avoid the above mentioned problems with CG, many game developers instead write all their shaders twice: in GLSL for OpenGL and in HLSL for DX or just ignore OpenGL and focus on DirectX.Р”В«ut the situation is improving because Scrawl made a library called РІР‚СљshinyРІР‚Сњ.

To make matters worse, CG is closed source and available for on Linux, windows, OSX and not on BSD. Again the problem is CG doesnРІР‚в„ўt provide good performance for the Radeon cards. Otherwise weРІР‚в„ўd just write our shaders in OpenGL. We need both DirectX and OpenGL support because Radeon graphics cards (built by amd) lack qualityР’В OpenGL drivers. This toolkit works with DirectX and OpenGL on all graphics cards, but only gives good performance with Nvidia cards (which is understandable since its developed by Nvidia). What does that mean for OpenMW? Until now we have been using the Nvidia CG toolkit. ScrawlРІР‚в„ўs new shader system has been merged into the main branch. Nhydock, another new developer, has taken the camera control task (which is composed of four or five subtasks). Both were very well done, so thank you _ greye and welcome to the team! Then he picked another one (maintenance in the item dropping code) and finished that in a short period of time. So letРІР‚в„ўs recap.Р”Р‡irst off, we have a new developer, _greye, who finished his first task (making CreatureStats into a class) in a single day. Though there wonРІР‚в„ўt be a new release for July, last week was a great one for OpenMW.
