them.
* Mercator/Terrain.cpp: re-order Segment building code in setBasePoint,

2005-04-12 James Turner <james@worldforge.org>
* Mercator/Shader.h: change checkIntersects to work on Segments
(as the comments suggest it originally did).
* Mercator/Terrain.cpp, Mercator/Terrain.h: when adding a shader,
clients must now specify a unique integer ID, which is used
to identify the shader in a Segment's surfacestore. As a result,
the Shaderstore is now a std::map<>. When adding shaders to
a Segment, checkIntersects is now used to only add shaders which
affect the segment.
* Mercator/Segment.cpp, Mercator/Segment.h: change Surfacestore to
be sparse, implement as a map, where the index value is the ID of
the shader which generated the surface.

Mercator/GrassShader.cpp, Mercator/GrassShader.h,
Mercator/ThresholdShader.cpp, Mercator/ThresholdShader.h:
update the revised shader API. In all cases the only change is
removed a level of indirection, since every implementation of
checkIntersect simply called 's.m_segment' to do useful work.

shader API.
2005-04-11 James Turner <james@worldforge.org>
* tests/timeSeg.cpp: fix up for changes to Forest API.

an area, replacing their own Box + Polygon storage, which was
only partially supported.
* tests/testForrest.cpp: update for changed Forrest API
* Mercator/Terrain.cpp, Mercator/Terrain.h: make Terrain track a list
of areas, and install them on newly created segments if required.
Necessary to allow Areas to be defined prior to segments they
may intersect.

* Mercator/AreaShader.cpp, Mercator/Area.cpp: remove #pragmas I
left in, which GCC moans about.

* Mercator/Forest.cpp, Mercator/Forest.h : modified seeding
arrangement so that number of rng seeds is proportional to
number of trees, not number of gridpoints. This significantly
speeds up forest generation and has the byproduct of improving

* Mercator/Surface.cpp, Mercator/Buffer.h, Mercator/Buffer_impl.h:
Modify buffers and thus surfaces to handle their memory
dynamically, providing facilities for allocating and
deleting the buffer.
* Mercator/Segment.h, Mercator/Segment.cpp: Implement easier
memory management, getting rid of the flags for points and
normals, using the value of the pointer instead.
Add a few to be called to cause the segment to free its
data, with the option to keep hold of the height field.

* Mercator/Terrain.h, Mercator/Terrain.cpp: Add new
getHeightAndNormal() method which makes available the method
of the same name from Segment on the whole terrain.

* Mercator/Shader.h: Add default arguments for constructor,
which default to alpha channel only.
* Mercator/ThresholdShader.cpp, Mercator/GrassShader.cpp,
Mercator/FillShader.cpp, Mercator/DepthShader.cpp:
Stop specifying arguements to the shader constructor, and thus
accept the defaults. Net effect is that surface buffers now
just contain alpha values by default.

* Mercator/Segment.cpp: fixed edge and corner normals.
2003-08-17 Al Riddoch <alriddoch@zepler.org>
* Buffer_impl.h: Add to distribution.
* Mercator/Segment.cpp: Make sure math functions are specified
as being from the global namespace, and add support for rintf
as its better than rint, and available under FreeBSD.
