Ran into performance problems – one of my procedural animated boxes is fast enough, but a hundred of them slows the machine to 10 fps.\u00a0 Even if I turn off animation.\u00a0 Which is pretty bad news, as I was planning to do the terrain from these or similar ones, and a 10×10 square terrain is pretty minimal.<\/p>\n

I’ll see if using vertex buffer objects instead of direct rendering will speed things up, if not I may drop to the Jam and write my own lightweight scala scenegraph on top of LWJGL<\/a> instead of using Sgine<\/a>, or maybe just redesign my terrain approach.<\/p>\n

My entry is on gihub<\/a> if anyone is interested, it also contains a detailed development journal<\/a> (sorry about the lack of line wrapping, github doesn’t seem to do it automatically for text files).<\/p>\n

Overall I fear I spent too much time on nice procedural models and too little on actual game mechanics..<\/p>","time":"August 22nd, 2010 4:28 am","title":"Crashing into the Performance Wall"}
