Hi Everyone,I've been trying to visualize a large scale network (20.000+ elements) in WPF and have some questions regarding the performance of the new Runtime.Somehow there seems to be a trade-off in performance of a regular grahpicslayer, and an accelerated graphicslayer.WPF: (20.000 lines on screen)- This moves very slow, and zooming/panning etc is cumbersome. - Updating the stroke of all the lines in view or getting the FindGraphicsInHostCoordinates lets say 10 times per second, it is very fast.Accelerateddisplay: (20.000+ lines on screen)- This moves very fluently and performs really well both when zooming and panning.- Updating the stroke of all the lines or trying to call findgraphicsinhostcoordinates is very slow I can't even get once per second updates.So the question is: what am I doing wrong, or is this a feature?EDIT: I've been trying to figure some things out. Main conclusion for now is: just setting the brush of all elements (20.000) takes a second (without doing anything else) in both WPF and Accelerated mode. So the trick seems be somewhere else. It looks like graphicslayer.FindGraphicsInHostCoordinates does not work properly in Accelerateddisplay.My code:
var graphics = glayer.FindGraphicsInHostCoordinates(new Rect(0, 0, Application.Current.MainWindow.Width, Application.Current.MainWindow.Height), 1000);
foreach (var g in graphics)
{
var pidx = (int)g.Attributes["index"];
var r = Simulation.TagValues["pressure"][pidx, timeindex];
var brush = GetColor(r);
var sym = g.Symbol as SimpleLineSymbol;
if (sym != null)
sym.Color = brush;
}
