Edit: Factor/GSoC/2010/Improve UI performance

= Mentor = [[Slava Pestov]] = Technical outline = Factor's graphical user interface library, written completely in Factor, could be faster if certain changes were made. - Factor's recently-added support for typed words, specialized arrays, and SIMD could speed up geometry and layout calculations. - Making better use of modern OpenGL could improve rendering performance. All vertex and texture co-ordinates for a single window could be combined into a single vertex buffer, instead of creating vertex arrays and switching them for each UI element. All textures for UI elements could be combined into a single texture atlas, instead of switching state for each element. = References = - The source code for the UI is found in %basis/ui/%. - [[http://docs.factorcode.org/content/article-typed.html]] - [[http://docs.factorcode.org/content/article-math.vectors.simd.html]] - [[http://docs.factorcode.org/content/article-specialized-arrays.html]] = Benefit to student = The student learns about UI design. = Benefit to community = UI applications in Factor run faster.
