@Elthon said in Is it possible to display a 3D surface graph from a 3D scatter graph in Qt C++?: @koahnig Hello, thanks for your reply. I have already checked on the example done by Qt. However, I am unsure about the rationale behind how they add data into the surface graph. For example, what is a row data in a surface graph? From the example you would need to have your data values on grid. In case you have no grid and only randomly distributed data points, you would need to get some interpolation onto a grid. That is the way Ihave done long before Qt. Unfortunately I have no experience with Qt3D in this respect.

Solve it... added to the .pro file QT += datavisualization

@m.sue Great find for the properties, and if I cannot find a way to tweak the rendering settings for draw distance then I guess that would be my best way to do it. Thanks.

@Wieland Thanks for the informations! In the Surface Example they only delete the Q3DSurface instance. But i will pass the parents to the classes, so i can be sure, that they are destroyed. Thanks!
