[Qt Visualtisation] Looking for a way to get started.

Vader

Hi!

Recently tried looked at the qt-visualization library examples and being very honest, the first thing that poped into my mind was: "I wanna do that too". Anyways, I have close to zero idea of how to get started. I read through the examples, but I always feel like something is missing in my understanding of the thing.

I would love to read some docs on Qt-Visualization. Might someone link me / guide me to where I can learn it?

Thanks

@Vader Did you already find this: http://doc.qt.io/qt-5/qtdatavisualization-index.html ?

Vader

Yea. I went though it already. I'll try to add more info.
I am more interested in the 3D Surface Rendering part of the library over the graph plotting part.
I was able to take a .png grayscale heightmap and was able to make a 3D Surface out of it and display it on a widget. I did however run into some problems such as :

I don't understand how to create custom 3D objects [I am not sure, but from my searches online, are they expecting me to use Unreal Development Kit?].
I have a lot of DT2 files for heightmapping. I realize I can convert them to grayscale heightmaps [though I haven't exactly tried doing it yet]; I would like to make the surfaces directly using DT2 files rather than the grayscale ones.
Then, I wish to render multiple such images while simulating movement. [I basically want to place a small car on the surface and move it while having the map move along with it keeping the car in the center], I dont see a way to partially render the images somehow.

I haven't done this stuff before, so I'd really love any help which I can get.
Thanks

I am not sure about the forum rules for this. So please forgive me and inform me if its wrong, but:
BUMP

@Vader Sorry, what was the intention of your last post?

I think you are more likely to find answers looking at qt3D There are already many examples to start off.
Data visualisation is mainly for showing data as the name says.

@Eddy I am currently trying to use https://doc.qt.io/qt-5/q3dsurface.html#details.
The class was a sub-part of the data visulatization index, so I went along with it. Thanks for correcting me. I'll look into the 3DRender class later.
