[osg-users] SubloadCallback and PBO cleanup
Hi all!
In my OSG application I need to continuously update small parts of 2D
texture. So I use osg::Texture2D::SubloadCallback:
class MyCallback :
public osg::Texture2D::SubloadCallback
{
/* initialize texture */
void load(const Texture2D texture,State state) const
{
/* get pixel buffer object extension functions */
osg::PixelBufferObject::Extensions* ext =
osg::PixelBufferObject::getExtensions(state.getContextID(), true);
/* generate and cache PBO ID */
ext-glGenBuffers(1, m_pbo);
if(m_pbo)
{
/* bind buffer */
ext-glBindBuffer(GL_PIXEL_UNPACK_BUFFER_ARB, m_pbo);
/* load texture initial data */
/* unbind buffer */
ext-glBindBuffer(GL_PIXEL_UNPACK_BUFFER_ARB, 0);
}
}
void subload(const osg::Texture2D tex, osg::State state) const
{
/* bind buffer */
ext-glBindBuffer(GL_PIXEL_UNPACK_BUFFER_ARB, m_pbo);
/* update some small part of the texture */
/* unbind buffer */
ext-glBindBuffer(GL_PIXEL_UNPACK_BUFFER_ARB, 0);
}
private:
GLuint m_pbo;
};
And everything works fine until the cleanup stage. In the code above
I've allocated a Pixel Buffer Object. Where should I place it's
deletion function (something like ext-glDeleteBuffers(1, m_pbo))? Or
I should generate/delete it on every subload call with performance
penalty?

[osg-users] Fast VectorArray inizialization.
Hi all,
I have some code like this:
float coordinates[]
...
... an external source fill the previous array ...
...
osg::ref_ptrosg::Vec3Array vertices = new osg::Vec3Array();
for (int i = 0; i 3 * numPoints; i += 3)
{
float x = coordinates[i];
float y = coordinates[i+1];
float z = coordinates[i+2];
vertices-push_back(osg::Vec3(x, y, z));
}
modelGeometry-setVertexArray(vertices);
I'd rather do something like this:
modelGeometry-setVertexArray_FromCArray(coordinates);
Is it possible? How?

Giulio

Re: [osg-users] Fast VectorArray inizialization.
Hi Giulio,
All osg::Vec*Array() are subclassed from the std::vector so you have
all the usual std::vector methods available. For examples of
different ways of initialization the array see the osggeometry
example.

Yes, have a look at the example osgsharedarray.
Of course you have to make sure the the array
is not freed until the last draw is finished.

Well, one never knows about ABI issues, but I was optimist because almost all linux distributions carry software compiled with several versions of GCC.

This make me wonder why your build with 4.4.3 isn't picking up on the atomic support correctly. Has anyone else had problems with picking up on the atmoic support? A reason can be the fact that some systems select different default architectures. If you are using a 32 bit system instead of amd64, and say your compiler is set by default to produce 586 or 686 compatible binaries, chances are that the gcc builtins are deactivated. You would have to specify the target architecture explicitly, eg. -march=native. Those default configurations can be checked with `gcc -v'. -- Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] [build] Build Issues Trunk 2.9.12 and GL3
Hi,
there are Build Issues with the current Trunk and the GL3 Option
osgText does not build due to glPushAttrib / glPopAttrib in
Text::renderWithDelayedDepthWrites.
osgSim OverlayNode Serializer uses Deprecated glTexEnv GL_DECAL Enum.
Fix for Text::renderWithDelayedDepthWrites:
void Text::renderWithDelayedDepthWrites(osg::State state, const osg::Vec4
colorMultiplier) const
{
#if !defined(OSG_GLES1_AVAILABLE) !defined(OSG_GLES2_AVAILABLE)
!defined(OSG_GL3_AVAILABLE)
glPushAttrib( _enableDepthWrites ? (GL_COLOR_BUFFER_BIT |
GL_DEPTH_BUFFER_BIT) : GL_DEPTH_BUFFER_BIT);
// Render to color buffer without writing to depth buffer.
glDepthMask(GL_FALSE);
drawTextWithBackdrop(state,colorMultiplier);
// Render to depth buffer if depth writes requested.
if( _enableDepthWrites )
{
glDepthMask(GL_TRUE);
glColorMask(GL_FALSE, GL_FALSE, GL_FALSE, GL_FALSE);
drawTextWithBackdrop(state,colorMultiplier);
}
glPopAttrib();
#else
OSG_NOTICE Warning: Text::renderWithDelayedDepthWrites(..) not
implemented. std::endl ;
#endif
}
Fix for osgSim::OverlayNode Serializer ( not sure if this one is sufficient,
but works )
#include osgSim/OverlayNode
#include osgDB/ObjectWrapper
#include osgDB/InputStream
#include osgDB/OutputStream
REGISTER_OBJECT_WRAPPER( osgSim_OverlayNode,
new osgSim::OverlayNode,
osgSim::OverlayNode,
osg::Object osg::Node osg::Group osgSim::OverlayNode
)
{
BEGIN_ENUM_SERIALIZER( OverlayTechnique,
OBJECT_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY );
ADD_ENUM_VALUE( OBJECT_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY );
ADD_ENUM_VALUE( VIEW_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY );
ADD_ENUM_VALUE( VIEW_DEPENDENT_WITH_PERSPECTIVE_OVERLAY );
END_ENUM_SERIALIZER(); // _overlayTechnique
ADD_OBJECT_SERIALIZER( OverlaySubgraph, osg::Node, NULL ); //
_overlaySubgraph
#if !defined(OSG_GLES1_AVAILABLE) !defined(OSG_GLES2_AVAILABLE)
!defined(OSG_GL3_AVAILABLE)
ADD_GLENUM_SERIALIZER( TexEnvMode, GLenum, GL_DECAL ); // _texEnvMode
#endif
ADD_UINT_SERIALIZER( OverlayTextureUnit, 1 ); // _textureUnit
ADD_UINT_SERIALIZER( OverlayTextureSizeHint, 1024 ); // _textureSizeHint
ADD_VEC4_SERIALIZER( OverlayClearColor, osg::Vec4() ); //
_overlayClearColor
ADD_BOOL_SERIALIZER( ContinuousUpdate, false ); // _continuousUpdate
ADD_DOUBLE_SERIALIZER( OverlayBaseHeight, -100.0 ); // _overlayBaseHeight
}
Moreover, think it would be a good Idea to add an Option to CMakeLists whether
to build osgQT, as QT includes GL.h. No fix for that :-)
For completeness, this Thread explains how to build OSG with GL3 option on
Windows ( tweak of osg/GL , tweak of CMakeLists.txt ) :
