Hi all (especially Martin), I was chatting with Mathieu trying to work out if there was a bug in 3d map views, but it turns out that it was just a misunderstanding on my part. I thought that if I had e.g. a pointz dataset (with z value set to dem spot height) and a dem, the points should always be placed exactly on the dem when altitude clamping = absolute.
It turns out that this is only the case if the dem vertical scale is set to 1.0. If I increase the scale, then the point z values aren't scaled to match and end up sitting below the dem. To me this is a bug, because vertical scale is a view dependent "data visualisation" setting only, and shouldn't require modification of the original data itself (i.e. manually scaling the point z values to match the vertical scale*). Is this intended behavior? (and if so, can it be rethought?) Nyall * this is non-trivial - there's NO easy way in qgis to scale z values (you'd need custom python code to do this) _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
