Hi,
I have posted a pic of the issue at http://austere3d.gallery.netspace.net.au/Unresolved/planetissue
I am experimenting with a planet model, I have taken a 129 x 129
heightmap and generated a 129 x 129 mesh and then mapped it around a
large sphere. The mesh is broken into four meshes
(64x64,64x65,65x64,65x65) and all four meshes are then rendered. I do
not do any translations as each mesh is created with the relevant
coordinates.
I get this issue in a lot of places around the planet, usually where
near mountains overwrite far mountains. I cannot see any overlap of
the heightmap cells, so I do not think cells are encroaching on the
space of other cells.
Is this a z-fighting issue? I am not sure how to resolve this issue at
present.
Cheers,
Richy
