Re: [osg-users] heightfield height

Hi, also when i use negative values in the setHeight() call, the heightfield draws seemed to got its origin in the x=0, y=0 coordinate of the viewer window? is it not allowed to use negative values as heightfield heights? Thank you! Cheers, Thomas -- Read this topic online her

[osg-users] heightfield height

Hi, i cannot find anything in the wiki about it, i got a heightfield set to a heightieldlayer and this one i set as elevationlayer to a terraintile. now i cannot find any doc about allocate, setXInterval and setYInterval. If i setup e.g. allocate(100,100) and set[X,Y]Interval(1.0), then i set a

[osg-users] display terrainTile

Hi, i got this little piece of code, with which i wanna display a heightfield. I read that for performance reasons one should use terrainTile and add the heightfield to it, but i dont get it to display in the viewer? i know the osgTerrain example, but i find it is too big for starting. i hope s

Hi, i inserted the dirtyDisplayList() into an update callback which i set with setUpdateCallback() and it works, but only if i click into the viewer window and move the heightField ? thanks for the help, i will try also the other variants, to see if they work better. Thank you! Cheers, Thom

Hi, i only have set ->setDataVariance(osg::Object::DYNAMIC); to the geode, now i also have set it to the shapeDrawable. Should i apply it only to the shapeDrawable or to both? After this change it draws the first point of my setHeight() changes, any following setHeight() call doesnt paint anyt

Hi, i created a geode and a heightfield, then i created a shapeDrawable with the geode as argument. After that i addDrawable to the geode, and the geode to the group. Now i can see the heightfield, but when i now try to change a height it does not update the frame? when i use dirtyDisplayList()

Hi, i can rotate an geometry when i use osg::PositionAttitudeTransform* rectangleTwoXForm = new osg::PositionAttitudeTransform(); and add the geometry with rectangleTwoXForm->addChild(rectangleGeode); then i can rotate the rectangleTwoXForm with e.g. rectangleTwoXForm->setAttitu
