i'm writing ios vertex shader "flattens" mc world in x direction if change in z direction detected, , vice versa (the xz plane perp height). have several shaders warp world fine, writing pseudo movement detection hasn't worked. know conditionals costly. comparing position number , worked: if (worldpos.x != 4.) { worldpos.z = 0.; } but comparing position static call of position doesn't. far i've tried assigning constant floats x , z components, uniform floats, , pos4 uniform, no success. have feeling conditionals fail because of data type problem? easier debug if pe version displayed coord pc. any/all help! current code: uniform pos4 chunk_origin_and_scale; attribute pos4 position; void main() { pos4 worldpos; worldpos.xyz = (position.xyz * chunk_origin_and_scale.w) + chunk_origin_and_scale.xyz; worldpos.w = 1.; const float staticposx = worldpos.x; const float staticposz = worldpos.z; if (worldpos.x != staticposx) { worldpos.z = 0.; sta...

i have several security cameras upload pictures ftp server. of these cams conveniently create subfolders @ start of new day in format "yyyymmdd". great , makes easy maintain/delete older pictures particular day. other cams aren't nice , dump pictures in giant folder, making deletion difficult. so writing c# windows form program go specific folder (source folder) using folderbrowserdialog , name target folder using fbd. using standard process iterate through file list using string array filled via directory.getfiles() method. use file's creation date create subfolder if doesn't exist. in either case move file date based subfolder. works great while testing small numbers of files. now i'm ready test against real data , i'm concerned folders having thousands of files, i'm going have many issues memory , other problems. how can string array handle such huge volumes of data? note 1 folder has on 28,000 pictures. can string array handle such large nu...
