Calculate bounding box of a set of indexed 3D points.
<p>This is much like <a class="normal" href="CastleBoxes.html#CalculateBoundingBox">CalculateBoundingBox</a>, except there are two functions: For each number in [0 .. VertsIndicesCount - 1] range, GetVertIndex returns an index. If this index is >= 0 then it's used to query GetVertex function to get actual vertex position.
<p>Indexes < 0 are ignored, this is sometimes comfortable. E.g. for X3D models, you often have a list of indexes with -1 in between marking end of faces.

<p>
State of collision between a plane and some other object.
<p>pcNone occurs only when the "other object" is empty (<a class="normal" href="CastleBoxes.TBox3D.html#IsEmpty">TBox3D.IsEmpty</a>, in case of box). Other values mean that the other object is not empty.
<p>pcOutside means that the whole object is on the side of the plane pointed by plane direction (normal) vector. More formally, every point P inserted into the plane equation will yield (P*PlaneNormal + PlaneD) > 0.
<p>pcInside is the reverse of pcOutside: the other object is on the side of plane pointed by inverted plane normal. Every point inserted into plane equation will yield < 0.
<p>pcIntersecting is, well, the remaining case. It means that there's for sure some point P of other object that, when inserted into plane equation, will yield = 0.</p>
