[osg-users] osgUtil::Tessellator getting back new structure.
Hi Every one, I am using osgUtil::Tessellator to tessellate a few polygons. However I don't want to use the viewer to draw them. I just want the vertices of the new structure returned. I am using the following options gtess-setTessellationType(osgUtil::Tessellator::TESS_TYPE_GEOMETRY); gtess-setBoundaryOnly(true); gtess-setWindingType( osgUtil::Tessellator::TESS_WINDING_POSITIVE) After running retessellatePolygons() How do I access the vertices of the new structure. I have tried getPrimList, but seem to be getting a few points that are way off.

Re: [osg-users] ODE Trimesh with OSG ?
Hi Carlos, I havn't got to osg::TriMesh (yet( so you'll have to dig the source on that.

Re: [osg-users] AutoTransform and SMALL_FEATURE_CULLING
Hi Sherman, I don't think your code is in error, nor that AutoTransform or small feature culling is in error, rather it's unfortunately chicken and the egg which came first? type dependency. The ways to break the culling of custom node in the first frame would be: To switch off small feature culling or set its value very low. To override the computeBound() of the AutoTransform so that it returns an invalid bounding sphere for the first frame till its been through the cull traversal once, once its been set correct then let the bounding sphere be computed correctly. To override the computeBound() of the AutoTransform so that it returns an large default bounding sphere for the first frame till its been through the cull traversal once, once its been set correct then let the bounding box be computed correctly. The two later solutions could possibly be rolled into AutoTransform itself. Robert.

Re: [osg-users] osgText - size is half of font resolution
Hi Sherman,
I download the FontForge http://fontforge.sourceforge.net/ editor on
sourceforge.
When I examine a Glyph of arial.ttf font with a size of 12 :
- A, there are 9 line for the glyph and 3 blank line under.
- a, there are 2 blank line on the top, 7 line for the glyph and 3
blank line under.
- q, there are 2 blank line on the top, 10 line for the glyph.
My conclusion is when you specify a size for a font,
this ensure that all glyph of the font have a height lesser to the specified
size.
But the place of the glyph is for someone largely over the base line ( for
example `),
and for other under the base line, _. So all the height is used by the
font.
Other source:
In Qt documentation, for a given Font, height is equal to ascend of this
Font
(space over the base line) + descend of this Font (space under the base
line)
+ 1 ( for the base line) pixels.
try attached example,
I take your code and adapt it in a main function.
I print text with height equal to the screen height
(1024 for me, modify the SCREEN_SIZE in file
osgtext_sherman2 : l.11 if you need). When the text is
display in fullscreen, you are sure that all text have
a height less or equal to the screen height,
many time the glyph height is half of the screen
height, but for some glyph ( for example the | or $ glyph)
the height is 3/4 of the screen height.

[osg-users] Getting current eyepoint

When I used the camera's view matrix, I seemed to be getting last frame's eyepoint - it hadn't been updated yet? When I changed my update callback to use the current matrix manipulator (fly,drive,etc) eyepoint, which had already been updated in the event traversal, I now got this frame's current eyepoint. Making my update callback a cull callback using the camera view matrix also worked. Is there a good way to get the current, updated eyepoint in an update callback? When does the camera view matrix become current? Thanks. Bob. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Getting current eyepoint
Hi Bob, The default setting of the view matrix is done at the end of Viewer::updateTraversal(), after the update visitor runs through the scene graph calling update callbacks. This is done so that any camera manipulators that track nodes can set themselves correctly. In your case you are looking for the camera position before its been set so in effect you only have the previous frames value. To get the correct value in an update callback you'll need to either dispense with using camera manipulators and set the view matrix yourself, or override the updateTraversal() so that the camera manipulators are set before the update traversal. The updateTraversal() method is deliberately written as a virtual function to allow you to customize it in such a way. Robert.
