From Richard Maunder:
Major changes to GL viewer to support:
i) Logical/Physical shape pairings
ii) Level of detail (LOD) scheme (TGLSphere only using at present)
iii) Common display list cache
iv) Scene rebuilds for large geometries
v) Some basic interactivity improvements - draw timeouts, drop low LOD
shapes etc
vi) New camara interactions:
Left Mouse: Rotate
Middle Mouse: Truck (pan parallel to camera film plane)
Right Mouse: Side-side drag dolly/zoom
Double click any button to reset the camera.
The previous pan with arrow keys, and zoom on mouse wheel are still
supported.
Camera interaction is default in viewer. These extra camera modes mean
there are not enough mouse buttons for previous right context/select.
To select / invoke context menu use Shift+Left Button and Shift+Right
Button respectively.

From Richard Maunder:
Changes to viewer infrastructure (TBuffer3D,TVirtualViewer3D) to
support:
i) Proper shape specific (sphere, tube, etc) descriptions in TBuffer3D
derived classes - c.f. abuse of raw tesselation blocks before.
ii) On demand filling of buffer sections as required by viewer.
iii) Support for local/master frame shapes descriptions & child object
rejection.
iv) Template/placed shapes ids - enabling viewer to detect/receive
common shapes once and just obtain the new position and id of the
duplicate.
Cleans up all producer (g3d/geom) code so no longer has an viewer
specific knowledge - Paint() methods replaced with
GetBuffer3D/FillBuffer3D methods which complete requested sections of
the buffer.
All viewer specific code now sits on the viewer implementation side of
TVirtualViewer3D. Added a TViewer3DPad class for performing the 3D draws
into pad. In future this should be merged with TView/TView3D possibly.
TBuffer3D is now stripped of functional code (aside from memory
management) and various viewer passback options there previously.
Enforced one way passing a const & to viewer.
Buffers (various types) are held as single static inside producer
function e.g. TGeoShape::GetBuffer3D (c.f. single generic buffer type
fetched from pad previously).
For g3d and geom shapes the top level geometry painter (TNode /
TGeoPainter) controlls painting process, requesting shapes to fill
buffer and passing to 3D viewer.
Exceptions are g3d's TPolyLine3D, TPolyMarker3D & TMarker3DBox. These
are 'standalone' shapes - no controlling 'painter' object. They still
implement Paint(), fill buffer and add to viewer directly.
3D viewer still held / created by pad - and pad has it's own viewer
object (TViewer3DPad).
NOTE:
1. Current scheme supports one 3D viewer only - pad, x3d or OpenGL. This
means that pad goes blank when x3d/OGL is spawned, and is updated again
when it is closed. To be revisited - need to support multiple viewers,
of multiple types - which implies explicit naming or pad controlling
enumeration.
2. OGL viewer now responds correct to modifications in pad, without
having to be reinvoked (as previously). x3d is still decoupled (as
previously) so does not rebuild - too difficult to get working.
