As shown at LinuxTag, with modifications from Tim Moore: the base
landmass texture is mixed with the steepness and snow effects. Till's
new syntax for textures in effect files was also added. syntax for
textures. Also, syntax for accessing internal textures, such as Till's
3D noise texture, was added.
Several bugs in the effect inheritance algorithm were fixed.
The material code constructs a property list from its input parameters.
Enable dumping of Pass and Technique objects to a file.
Default effect now uses texture node instead of texture0
Polymorphic additions to expressions: Add an expression base class
with a method for dynamically determining the type of an expression.
Add variables, predicates and boolian expressions.
Support for parsing trees of expressions
An SGRawBase class has been added as a base class to the SGRawValue
hierarchy so that SGPropertyValue functions don't necessarily need to
know the type of the value stored in the node.
A new SGRawValueContainer class stores properties that shouldn't be
stored in the node itself. PropertyTraits indicates if a type is
stored in the property node or externally.
Add getValue and SetValue template member functions to SGPropertyNode.
Read and write new extended properties.
Rearrange props.hxx a bit so that the template magic actually works.
Split out extended raw value virtual functions into a seperate base class.
SGRawExtended is chosen as a base class of SGRawValue for extended property
types.
Change most uses of the SGPropertyNode _value union to use static_cast.
Move SGPropertyNode::Type out of the class into simgear::props namespace. Add
a PropertyTraits class so that templates can calculate the property type tag
based on a C++ type.
In destructor, delete _value.val if it is not 0 (and the property is not
aliased).
Make sg_throwable inherit from std::exception.
change exception objects to contain C strings: exception objects should not
include objects, like std::string, whose copy constructor could throw.
This can chew up large amounts of memory for questionable gains. We do
let the tree model geometry be in a display list if OSG chooses to put
it there.
Various renaming and cleanup. Save some memory by reverting
ShaderGeometry's base class back to osg::Drawable.
This reverts back in the direction of Yon's original patch: the model is
drawn within ShaderGeometry::drawImplementation. This saves a lot of memory
over the previous approach of creating a PrimitiveSet for each model.
This eliminates jitter and other rendering problems.
For the moment this is dependent on an osg fix.
Also, don't read wind properties from FlightGear; provide a mechanism
for fg to set the wind.
It is not safe to call this function from the database pager thread;
in any event, state sets and textures created in the database pager
will get passed through the SharedStateManager anyway.
<iostream> sucks in expensive initialization of the standard streams
and isn't appropriate in a header file. Use <istream> and <ostream>
instead.
using declarations should never appear at global scope in a header
file; source files get to decide what they want to use in their
namespace.
It turns out that the database pager causes the texture image to be
unloaded after it is applied, so the image and its file name may not
be available for doing the livery substitution. Ask a work around we
set the name of the texture to its file name.
Also, add a NodeAndDrawableVisitor that descends into osg::Drawable.
That motivation for this is that it's a bad idea to modify state sets
that the osgDB::SharedStateManager might be keeping.
Add more points to the dome, giving it a dome shape rather than a
dunce cap shape.
Represent as OpenGL DrawElements instead of as triangle strips.
Only calculate have the sky colors and reflect those across the dome.
The change to set the light group node mask to LIGHTS_BITS caused
VASI/PAPI lights to not be displayed during the day. This patch fixes
that and optimizes VASI creation a bit.
Comments from Till:
I started the project at the end of february with a simple idea: move all
3d-model loading to the DatabasePager-thread. my first attempts looked
promising, though they were a little too optimistic (or naive?). the patch
has evolved a lot since.
currently it does the following things:
1. revive SGModelLib, move functions for xml-model-loading there
2. replace all calls to sgLoad3dModel with calls to either
SGModelLib::loadModel() or SGModelLib::loadPagedModel()
almost all models will be loaded by the DatabasePager. the few exceptions are:
your own plane, shared models in scenery, random objects, AIBallistic models.
3. simplify mode-loading functions (avoid passing around fg_root)
4. avoid supurious MatrixTransform nodes in loaded models
5. fix some memory leaks
Reindent everything to Stroustrup style and make member variable style
consistent.
Remove unused header files.
SGPrecipitation is now a subclass of osg::Referenced.
Initialize snow and ice intensity to 0 directly. The methods that set
the intensities change the value slowly and so don't work when the
initial value is garbage.
