Re: [osg-users] Bug in osgText::drawForegroundText

Hi,

can you make it crash in singlethreaded mode? If not, check all settingsof "dynamic" on text nodes.

    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.
