readFontStream() to load fonts from a std::istream, rather than from the
local filesystem by name. Such a call may be used, for example, if the
user has a font fetched over a network, or a font available in memory
without a correspondng filename.
The changes implement the new function by following the corresponding code
for readFontFile(). readFontStream() reads a stream into memory, and
holds that memory for FreeType.
As a basic test, I mangled the osgtext example to use
readFontStream(std::ifstream("font")) in lieu of a readFontFile call, and
the modified example ran completely."
SGIX_blend_alpha_minmax and EXT_blend_logic_op extensions. It is
tested with the osgblendequation example. If the extensions are not
supported, a WARN level notification is generated."
the viewport, the clear colour and the subgraph needing rendered. This is done
transparently so all existing functionality will behave as before. What it does
add is the ability to set a SceneView directly by a single osg::CameraNode when required.
into line with OpenGL shader languague conventions.
From Robert Osfield, changed the SceneView::ActiveUnforms enum to from INVERSE_VIEW_MATRIX_UNIFORM
VIEW_MATRIX_INVERSE_UNIFORM to be convistent with the above change.
Fix to the update of the error metrics on the edges in the simplification mesh that are affected by an edge collapse.
Addition of 'n' and 'p' keyboard control in osgsimplifier example to allow users to control the sample ratio manually.
1. type converters created automatically by the I_BaseType macro use
static_cast<> even for base-to-derived conversions. dynamic_cast<> should be
used instead.
2. as a consequence of the above fix, I_BaseType must now differentiate
between polymorphic and non-polymorphic base classes, because the latter
can't be dynamic_cast'd to derived classes. Some template magic (see
is_polymorphic<> in ReflectionMacros) is used to detect polymorphism at
compile time (I'm NOT sure it works on all platforms as it's partly
implementation-dependent. Please test!).
3. predefined custom property getters/setters/counters/etc. (as those
defined for STL containers) only work on Value objects that contain
non-pointer instances. This was an unwanted restriction that no longer
exists.
Wrappers will need to be recompiled. This is a good time to give them a
fresh update with genwrapper.
NOTE: fix#1 should get rid of those crashes and strange behaviours that
some users noticed while using osgIntrospection through osgTcl or in their
own code."
option for using or not using geom's indices for tangent space vectors
generation. now, Ruben's code is also used (it was disabled before). in
order to keep backward compatibility, the compute method behaves as before
in default case."
Spelling fixes in include/osg/LOD
Negated priority in PagedLOD when using _rangeMode==PIXEL_SIZE_ON_SCREEN
Added clampedPixelSize() methods to CullStack and CullingSet to return fabs()ed values.
Changed LOD and PagedLOD ::traverse to use clampedPixelSize() methods.
