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).
Extend SGAtomic with atomic exchange and add.
Import updates from the original implementation of that in OpenFDM.
