co-planar polygon jitter - suggested solution?

I wonder what is the suggested solution to avoid jitter (z-fighting)
when co-planar polygons are rendered. typically the polygons are
overlapping, but not totally identical. (and they are vertical if this

should one identified these polygons and join them, and just render a
single polygon?

in this case, how would be this done the easiest way if the polygons
belong to different objects (primitives)? would one go through all the
primitives, and basically remove the overlapping polygons and add
'joined polygons'?

moreover, how could this be done so that picking by mouse click would work?

a sample of this issue can be seen here: -
where the vertical sides of the displayed spaces are overlapping
co-planar polygons

Hi Akos,

For this example, joining the geometry would be ideal. As I mentioned before, I am working on something that would help, especially for picking. I’ll have a progress update in a few days. Keep your eyes open for a mail on “Static Geometry Batching.” There is some early work in this branch.



thanks, I’m really glad to hear this.
is there any specific way I can help out?


Thanks for the kind offer. I’ll certainty have some suggestions in a few days. :slight_smile:


great :slight_smile:
