Hi Gandalf, You can pass variables in the command line cmake -DVAR=VALUE, or you can install ccmake and set them in the ncurses UI. ccmake also takes -D, just like cmake. Laurentiu On Mon, Jan 13, 2025, at 17:31, Gandalf the Gray via QGIS-Developer wrote: > Hi guys, very newby question here.

Hi, my 2 cents from a 3D-interested (not yet experienced) user: 1. doing GIS-stuff on a notebook, no matter how performant it is, for me is a PITA. Clumsy keyboards, overpriced hardware. GIS-work without a large or 2 screens is useless -> so whats the point of a mobile computer then? 2. Had a 10

Hey Luke Low end graphics cards should work fine as well. If your coworker could not run 3D on his laptop, it could have been some other problem - it would be good to have more details (hardware spec, operating system, in what way things did not work) so that we can fix such issues. For example, m

Hi Luke, The higher end card should indeed give you better performance. However, there is a hard coded limit in QGIS 3D at the moment. A 3D scene cannot load more than 500 Mo of 3D objects even if you video card has a lot of available memory when the 3D scene is created. The idea is to avoid o

Is it correct that the 3D engine currently does not understand measurement values in 3DM format. When having four numbers in a coordinate the z (and m) value is skipped rendering the geometry af terrain = 0 meter (any 2d layer in 3D map is default rendered at z=0). Example: /SELECT 1 AS

Hi Calvin I have tested with your layer and the problem is with the no-data values - right now the terrain generator does not have a concept of no-data values so they are interpreted as valid values, which in this case is a very high number (around 1e38) and that breaks the 3D view. Best to keep a
