Subject: Treat an empty bounding sphere as absent for frustum culling
X-Git-Url: https://git.tdb.fi/?a=commitdiff_plain;h=d382f7524de37bd07693f0fa1795d3a3085a32ec;p=libs%2Fgl.git

Treat an empty bounding sphere as absent for frustum culling

Dynamically created objects don't have their bounding sphere filled
in, so they got culled when the center of the object was outside the
frustum.
