I need to highlight an area in a hexagonal field with lines on the ground. Right now I’m using a simple quad model for a segment of the line, which looks great, but the problem is that results in ~100 geom nodes, which slows down rendering by about 20fps.
I can call flattenStrong on it, which recovers the fps, but this takes too long to do on one frame. There is a noticeable pause as flattenStrong executes (the call alone slows the fps down to 20 for that one frame). It should be noted I may need to redraw the lines about once every 5-10 seconds, so it’s very noticeable when it happens.
So is there a way to get the best of both worlds? Some way to append models to a geom so I don’t need to call flattenStrong on them at the end? Or at worst some way to spread flatttenStrong over a few frames.
Alternatively, could I get some speedup by precombining some of the models? That is, instead of adding a new model for each edge of a hexagon in turn, deciding which of the precombined models the hexagon needs to show and adding only that. It would possibly halve the number of models to be flattenStronged, but I don’t know if that’s the bottleneck, and wouldn’t help me on some cases where there are many hexagons with only one line to show.
