@donotme

These are the edges of your graph (I think so).

Does this area change, when moving the camera?

donotme

@Pl45m4 Yes,when change the camera,the gray area is changing simultaneously. The graph has many sharp edges.

@donotme

It's a render thing. I guess you can't change that (at least I dont know how)

@Pl45m4 yes, i try many apis in Q3DSurface, such as Q3DLight, Q3DCamera,scene and have no use. Anyway, thank you!
