TileMap incorrectly culling tiles when using perspective camera
Unknown
Member
Hi!
I've been using Gideros in the couple past days, and I like the experience so far
. Thank you all for the good work!
I've encountered a first problem though which feels like a bug. Namely, when using TileMap with the perspective camera (through Application:configureFrustum), the outermost tiles are being culled on the screen, most likely due to the culling computations not taking the Z coordinate into account. I have found another topic which seems to be related: giderosmobile.com/forum/discussion/5557/what-about-some-basic-3d-support-in-gideros-/
I've attached a minimal project to showcase the issue. Hopefully it's only me who does something in a wrong way
.
Also, the documentation for Application:configureFrustum doesn't include the nearplane parameter which actually seems to be there in the underlying code. However, even when not using it explicitly, and it being defaulted to 0 (github.com/gideros/gideros/blob/983bdfd7ef307e48fd91a36231820242d8d93b23/luabinding/applicationbinder.cpp#L650), I can still put objects with the positive Z coordinate, and these objects only get culled at some random (as in: not obvious), big positive Z number.
P.S. "You can't post links" forum message is a bit unexpected...

TileMaps are basically the only ones having off screen culling, and most probably new 3D additions do not take that into consideration.
Can you add it as an issue to github?
