I am trying to create a 3d model of an archaeological site on QGIS. I had some contourlines, I made them polygons using the "polygonize" plugin and I categorized the polygons with a colour scale according to the altimetry value of each polygon.
At this point I used the 3d view in the layer properties panel to get a 3d view of the "polygons overlapping" effect. The value of the extrusion is the one found in the ELEV_2 field (i.e. the value of the height of each polygon).
The result is this:
There are two questions:
- How do I keep the colour scale I used for the 2d symbology?
- Is there a way to decrease the height of the base of the model?
I have already used Qgis2threejis. Unfortunately every time I try to open this layer with this plugin the pc freezes.
I have already tried this solution but applied to my case it does not respect the height increase of the polygons Jochen Schwarze's solution
