Project: QGIS
Version: 3.4 LTR
This mode of 3D line rendering will use OpenGL line rendering instead of buffering lines into polygons and rendering them as meshes.
The advantage is that the 3D lines do not loose their Z coordinate which is the case currently with "ordinary" 3D rendering after buffering.
The disadvantage is that the lines cannot be wide (supported in Qt3D only since 5.10, but even then their rendering won't have nice joins/caps) and only ambient color is used from the material.
