v9 v10 25 25 == Motivation == 26 26 27 With complex maps, it's more efficient to render one large tile than many small ones. 28 There is little or no benefit for simple maps like the Sheboygan Sample. 27 With complex maps, it's more efficient to render one large tile than many small ones. In our particular case rendering time for the full map takes up to a week! 28 However, there is little or no benefit for simple maps like the Sheboygan Sample making testing a bit tedious. 29 29 30 Using our 140 layer example map we can observe the following timing using metatilefactor 1 & 4 31 and 3 different locking strategies in the attached chart MetatilingChart1.jpg. 30 Using our 140 layer example map we can observe the following timing using metatile factor 1 & 4 31 and 3 different locking strategies in the chart below. Unfortunately, the used hardware was not powerful enough to clearly differentiate the effect of the different locking schemes. However, it clearly shows the speedup by using metatiles as such. 32 33 [[Image(MetatilingChart1.jpg)]] 32 34 33 35 == Proposed Solution ==
