Definition at line 445 of file qgs3dmapsettings.h.

When enabled, in addition to the terrain texture generated from the map, the terrain rendering will take into account position of the lights, terrain normals and terrain shading material (ambient and specular colors, shininess).

float Qgs3DMapSettings::maxTerrainGroundError | ( | ) | const |
Returns maximum ground error of terrain tiles in world units.
This parameter influences how many zoom levels there will be (together with mapTileResolution()). This value tells that when the given ground error is reached (e.g. 10 meters), it makes no sense to further split terrain tiles into finer ones because they will not add extra details anymore.
Definition at line 537 of file qgs3dmapsettings.cpp.
|

float Qgs3DMapSettings::maxTerrainScreenError | ( | ) | const |
Returns maximum allowed screen error of terrain tiles in pixels.
This parameter decides how aggressively less detailed terrain tiles are swapped to more detailed ones as camera gets closer. Each tile has its error defined in world units - this error gets projected to screen pixels according to camera view and if the tile's error is greater than the allowed error, it will be swapped by more detailed tiles with lower error.
Definition at line 523 of file qgs3dmapsettings.cpp.

|
inline |
Sets coordinates in map CRS at which our 3D world has origin (0,0,0)
We move the 3D world origin to the center of the extent of our terrain: this is done to minimize the impact of numerical errors when operating with 32-bit floats. Unfortunately this is not enough when working with a large area (still results in jitter with scenes spanning hundreds of kilometers and zooming in a lot).
Need to look into more advanced techniques like "relative to center" or "relative to eye" to improve the precision.
