question i'm developing poker software ~ purely fun. now when comes chips, i'm having nightmare. 1 positioning them, 2 denominations , three selecting ones i'll need! seems impossible current design. basically, draw skshapenode give name of denomination , player name. however, chip can drawn 50 times same name. when come animating these chips, can see wall of impossibility.. once i've made function choose right denominations of chips use call or raise etc, how begin write pseudo code? i require 2 large chips, 1 small chip , 2 medium chips { sknode *node = [self childnodewithname:denomination, playername]; runaction.. } baring in mind, i'll need take 2 of 20 there in chip stack.. change ownership of chip.. is possible? or overcomplicating issue..? you need rework solution little bit. this: first, subclass skspritenode (or sk whatever node like) make chip: chip.h @interface chip : skspritenode @property (nonatomic, retain)...

i have stack of 4 rasters. average correlation through time between pixel , each of 8 neighbors. some data: library(raster) r1=raster(matrix(runif(25),nrow=5)) r2=raster(matrix(runif(25),nrow=5)) r3=raster(matrix(runif(25),nrow=5)) r4=raster(matrix(runif(25),nrow=5)) s=stack(r1,r2,r3,r4) so pixel @ position x, has 8 neighbors @ ne, e, se, s etc positions, want average of cor(x,ne) cor(x,e) cor(x,se) cor(x,s) cor(x,sw) cor(x,w) cor(x,nw) cor(x,n) and average value saved @ position x in resulting raster. edge cells na or, if possible flag calculate average correlation cells touches (either 3 or 5 cells). thanks! i don't believe @pascal's suggestion of using focal() work because focal() takes single raster layer argument, not stack. solution easiest understand. made more efficient minimizing number of times extract values each focal cell: library(raster) set.seed(2002) r1 <- raster(matrix(runif(25),nrow=5)) r2 <- raster(matrix(runif(25),nr...

i'm trying write fast 3d lut lookup function , noticed luts either 33x33x33 or 17x17x17. why 33 or 17? wouldn't math quicker 32 or 16 instead? shifts instead of divides? or maybe i'm not understanding why. anyone? this because colour values typically stored 8-bit or 10-bit integers (8 bits in systems each r, g , b value stored in single byte, , 10 bits in systems store 30 bits of rgb data in 32-bit long word). to achieve spread of rgb values across entire range, need choose lut size evenly covers range 0 255 or 0 1023. since 255 = 17x15, lookup table 15 or 17 values you: 15 values: [0, 17, 34, 51, 68, 85, 102, 119, 136, 153, 170, 187, 204, 221, 238, 255] 17 values: [0, 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255] for 10-bit values, i'll note 1023 divisible 33. can maths :-)
