There is at least 2 problems with this approach:<br>
1) it is slow and inefficient<br>
2) if there are some shapes in the SVG, I do not have real points, I need to<br>
create the points first, for example, I have 2 centers and 2 radiuses for an<br>
ellipse, so I can generate some points on this ellipse' curve.<br>
This makes the process even more slow.<br>

What would be a more efficient approach, if there is one?<br>
Thanks<br><br></blockquote><div> </div><div>From a complexity standpoint there can't be a more efficient way to do this than you have described. You need to iterate over the points in the SVG file at least once, which you do in your algorithm. There may be tweaks you can do such as generate points with the same x,y value and different z values at the same time and store these in your mesh, but that is a constant performance improvement. Unless you are dealing with billions of points, what you describe should be quite fast on any computer.</div><div><br></div><div>Cory</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
