Detailed Description

OpenGL 3d graphics driver.

Notice that it is suppesed to use only with QSAxes3D.and it uses Qt for drawing 2D, text etc.

Member Function Documentation

bool QSDrvOpenGL::alpha (    )  const [inline]

Returns alpha setting.

virtual CColors QSDrvOpenGL::cColors (    )  const [virtual]

Returns a color mode required by this driver. Reimplemented from QSDrv.

virtual CNormals QSDrvOpenGL::cNormals (    )  const [virtual]

Return a normals mode required by this driver. Reimplemented from QSDrv.

virtual QSDrvOpenGL* QSDrvOpenGL::copy (    )  [virtual]

Returns new copy of this driver with all settings set. Reimplemented from QSDrvQt.

void QSDrvOpenGL::copySettingsFrom (  const QSDrvOpenGL *    drv )

Copies all settings from another driver

virtual COrdering QSDrvOpenGL::cOrdering (    )  const [virtual]

Returns an ordering required by this driver. Reimplemented from QSDrv.

virtual void QSDrvOpenGL::drawLine3 (  const QSPt3f &    begin, const QSPt3f &    end, const QSPt3f    norm[2] )  [virtual]

Draws a line. Default implementation maps 3d points on 2d plane and draws 2d line. Reimplemented from QSDrv.

int QSDrvOpenGL::globalTransparency (    )  const [inline]

Returns global transparency

void QSDrvOpenGL::init (  QSAxes3D *    parent )

Prepare driver

bool QSDrvOpenGL::meshAutoStroke (    )  const [inline]

Returns if mesh auto stroke colors is enabled

int QSDrvOpenGL::meshAutoStrokeLightness (    )  const [inline]

Returns how much auto stroke is lighter than mesh fill color.

QSAxes3D* QSDrvOpenGL::parentAxes (    )  const [inline]

Returns parent axes

void QSDrvOpenGL::setAlpha (  bool    enabled )

Enable/disable alpha.

void QSDrvOpenGL::setAutoStrokeLightness (  int    value )

How mush mesh stroke is lighter than a mesh fill

virtual void QSDrvOpenGL::setClipping (  bool    enabled )  [virtual]

Turns on clipping when drawing ( ..2(), *3() methods ). Must be called after startDrawing() Always clips polygons,lines,points using clipPoly2,clipLine2,clipPoint2,clipPoint3, clipPoly3. Reimplemented from QSDrv.

virtual void QSDrvOpenGL::setCurrentElement (  int    category, int    element )  [virtual]

Sets a currently drawn element. It has no meaning for this objects - just a pair of ints. It is called by a graphic object, which uses this driver. It can be used for example in QSHitDrv to see what part of an object was exacly hit by mouse. It can be read, but further interpretation must be done in an other place. It is reset to -1, -1 in stopDrawing(). See QSAxes::ElementCategory Reimplemented from QSDrv.

virtual void QSDrvOpenGL::setDC (  QPainter *    p, double    dpi = 72, bool    deletePainter = false )  [virtual]

Sets a painter for this driver. If deletePainter is true, painter will be deleted in destructor. If p->device() isn't an external one, no world or view transformation of the painter are used. Reimplemented from QSDrvQt.

virtual void QSDrvOpenGL::setFill (  const QSGFill &    f )  [virtual]

Set the current fill . Reimplemented from QSDrvQt.

void QSDrvOpenGL::setGlobalTransparency (  unsigned char    value )

Global transparency

virtual void QSDrvOpenGL::setLine (  const QSGLine &    l )  [virtual]

Set the current line style. Reimplemented from QSDrvQt.

void QSDrvOpenGL::setMeshAutoStroke (  bool    enabled )

Mesh stoke auto-colors

void QSDrvOpenGL::setShadeWalls (  bool    enabled )

Shade walls

bool QSDrvOpenGL::shadeWalls (    )  const [inline]

Returns shade walls setting

virtual void QSDrvOpenGL::startDrawing (    )  [virtual]

Reimplemented from QSDrv::startDraw . Reimplemented from QSDrvQt.

virtual void QSDrvOpenGL::stopDrawing (    )  [virtual]

Reimplemented from QSDrv::stopDraw . Doesn,t call paint->end(). Reimplemented from QSDrvQt.
