What are the controls / libraries to display a large array of points? Win2d tried, it works disgustingly. But the problem is not in the algorithm, because the project on winforms with its GDI + and the same code just flies
- How big is the array? - Andrei NOP
- Andrew, 5k elements - Ttphm Nov.
- And why just do not draw the points manually on the canvas, for example? - Andrei NOP
- Is this a joke? Canvas and 500 barely withstand. maybe I don’t do it through those methods, but I usually use the for {var mypoint = new Ellipse () loop; canvas.children.add (mypoint)}. I don’t need to say that every time I initialize an object of an ellipse structure, I haven’t found another method. for win2d, of course, the structure is created only once before the loop. then through the attributes .x and .y I assign new values for the drawing. Nevertheless, the performance is still terrible. - Ttphm
