i'm trying obtain 4x4 projection matrix transforms point in world display coordinates. having pixel (x, y) , corresponding z-value (from zbuffer ), obtain 3d world coordinates vtkworldpointpicker class. let's denote result x . according documentation , can compute view coordinates of world point applying matrix getcompositeprojectiontransformmatrix x . next, i'm using transformation view initial display coordinates using code found in vtkviewport::viewtodisplay (*): dx = (v[0] + 1.0) * (sizex*(v[2]-v[0])) / 2.0 + sizex*v[0]; dy = (v[1] + 1.0) * (sizey*(v[3]-v[1])) / 2.0 + sizey*v[1]; where sizex , sizey width , height of image in pixels, , v computed view coordinates. unfortunately, values not match original: display [0, 0, 0.716656] // x,y-pixel coordinates , zbuffer x = [0.0255492, -0.0392383, 0.00854707] // world coordinates (using vtkworldpointpicker) // camera->getcompositeprojectiontransformmatrix p = [ -1.84177 0 0

on postgres, saw case there huge amount of selects being handled in single transaction. slow, solution break selects multiple transactions, dramatically improved query time. has come across such case? seems counter intuitive , wondering if there technical reason why multiple transactions preferable? my theory it's easier db maintain acid properties multiple transactions opposed single gargantuan transaction. i wouldn't expect selects issue if there nothing writing database. there aren't locking issues there speak of in pure select statement. issues happen when there writes. if have writes, have deal fact autovacuum cannot clean items written after oldest write transaction started. if seeing issues this, critical investigate locks (in pg_locks ) can queries , functions , find out these coming from. keep in mind select not select , easy assume performance problems coming from.
