Hi,
Well I started my thread earlier with title as custom QQuick3D text but I
couldnot get any response.
Iam getting issues in drawItem() of below code that I tried so far:-
Class TextItem3D: public QQuickItem3D
{
Q_OBJECT
Q_PROPERTY(qreal xPos READ xPos WRITE setXPos NOTIFY positionChanged)
Q_PROPERTY(qreal yPos READ yPos WRITE setYPos NOTIFY positionChanged)
Q_PROPERTY(QString textString READ textString WRITE setTextString NOTIFY
textStringChanged)
Public:
Explicit TextItem3D(QObject *parent=0);
~TextItem3D() { }
qreal xPos() const { return x;}
void setXPos(const qreal &xPos);
qreal yPos() const { return y;}
void setYPos(const qreal &yPos)
qreal zPos() const { return z;}
void setZPos(const qreal &zPos);
QString textString() const { return mTextString;}
Void setTextString(const QString &);
Q_SIGNALS:
void positionChanged();
void textStringChanged();
protected:
void drawItem(QGLPainter *painter)
private:
qreal x,y,z;
QString m_TextString;
QGLSceneNode *m_geometry;
bool m_ChangeFlag;
};QML_DECLARE_TYPE(TextItem3D)
void TextItem3D::setXPos(qreal xPosition)
{
If(x!=XPosition)
{
x= XPosition ;
m_ChangeFlag = true;
emit PositionChanged();
update();
}
Void TextItem3D::drawItem(QGLPainter *painter)
{
If(m_ChangeFlag || m_Geometry) {
If(m_Geometry) delete m_Geometry;
QGLBuilder builder;
QGeometryData textCollection;
builder.newSection();
//INSERT Bitmap text OpenGL code like Points or Line
builder.appendAttribute() //wrong….?
builder.CurrentNode() ->setX(x);
builder.CurrentNode() ->setY(y);
builder.CurrentNode() ->setZ(z);
builder.CurrentNode() ->setDrawingMode();//wrong …?
m_Geometry = builder.finalizedSceneNode();
m_ChangeFlag = false;
}
m_Geomtery->draw(painter);
}
Thanks and Regards,
Ramakanth

Hi,
It would be preferable if you start your own thread.
I'm sorry but I cannot help. I still don't know how to create custom Item3D.
Olivier.

Hi,
I would like to see Text in 3D space as I had been trying hard for the last
week to render text in 3D space using custom QQuickItem3D but somehow couldnot
manage to render text.
Your help in this is greatly appreciated.
Best Regards,
Ramakanth

For use of it yes this is fine. For development of it development@ would be
better.

Glad to see there is interest in this module :)

Yes that agrees with my experiences too.

Short answer, no. As you say it is partially usable. However, there has been
some bit-rot as other modules have developed and Qt3D has stagnated given the
situation this year.
Longer answer is that we are discussing what we wish to do with Qt3d in the
longer term. As a result I cannot promise that the API will not change at this
stage.
If you have specific features you would like to see then please raise them in
JIRA or on the mailing list.
One major idea that we have had is to provide integration between Qt5 and
other scene graphs such as OpenSceneGraph and OGRE.

There is a patch pending to fix this:
https://codereview.qt-project.org/#change,40458
However, some other stuff needs to go in first to allow the CI system to
actually pass. There's a few other tidy-up's pending too. I will hopefully get
these sorted out this week now that devdays is over.

Not sure about this one off-hand. I'll take a look once the other patches are
merged.
Kind regards,
Sean
