I think there is a real bug in the rendering of OsgText. (2.6.1 release)
The bug does appear randomly... I get it with simple text in a Hud, updated
each frame.
The bug is there :
*void Text::drawForegroundText(osg::State& state, const GlyphQuads&
glyphquad, const osg::Vec4& colorMultiplier) const
{
unsigned int contextID = state.getContextID();
const GlyphQuads::Coords3& transformedCoords =
glyphquad._transformedCoords[contextID];
if (!transformedCoords.empty())
{
state.setVertexPointer( 3, GL_FLOAT, 0,
&(transformedCoords.front()));
state.setTexCoordPointer( 0, 2, GL_FLOAT, 0,
&(glyphquad._texcoords.front())); //HERE : glyphquad._texcoords is void,
but seems initiated
//VS degogeur
said content is [0]()
if(_colorGradientMode == SOLID)
{
state.disableColorPointer();
glColor4f(colorMultiplier.r()*_color.r(),colorMultiplier.g()*_color.g(),colorMultiplier.b()*_color.b(),colorMultiplier.a()*_color.a());
}
else
{
state.setColorPointer( 4, GL_FLOAT, 0,
&(glyphquad._colorCoords.front()));
}
glDrawArrays(GL_QUADS,0,transformedCoords.size());
}
}*

I just tried it with osg SVN : nearly the same error
in :
*void Text::renderOnlyForegroundText(osg::State& state, const osg::Vec4&
colorMultiplier) const
{
for(TextureGlyphQuadMap::iterator titr=_textureGlyphQuadMap.begin();
titr!=_textureGlyphQuadMap.end();
++titr)
{
// need to set the texture here...
state.applyTextureAttribute(0,titr->first.get());
const GlyphQuads& glyphquad = titr->second; //HERE : titr->second
seems to be invalid (VS said more than 800 000 000 _glyphs ...)
drawForegroundText(state, glyphquad, colorMultiplier);
}
}*

Do you have any suggestion ? what can cause this problem ?
Thanks a lot.

Vincent.
