Hi,
We are developing a simple 3D viewer to display the DEM and overlay a
trajectory (vector layer) as a simple 3d lines. It is working fine and
vector file is draped on to the terrain. We want to display the vector
file as simple 3d lines.
We could see the same in QGIS application by setting the Vector Layer
properties 3D View => Render as simple 3D lines.
Trying to set same programmatically, but getting the following error.
" ..\..\..\src\3d\qgsvectorlayerchunkloader_p.cpp(57) :
(QgsVectorLayerChunkLoader::QgsVectorLayerChunkLoader) [15960ms]
Unknown
3D symbol type for vector layer: line "
The following code snippet used:
if (pcLyr != nullptr) {
std::unique_ptr< QgsLine3DSymbol > sym = qgis::make_unique<
QgsLine3DSymbol >();
std::unique_ptr< QgsPhongMaterialSettings > mCurrentSettings;
mCurrentSettings = qgis::make_unique< QgsPhongMaterialSettings >();
sym->setWidth (1);
sym->setHeight (0);
sym->setExtrusionHeight(0);
sym->setAltitudeClamping(Qgs3DTypes::AltClampAbsolute);
sym->setAltitudeBinding(Qgs3DTypes::AltBindVertex);
sym->setRenderAsSimpleLines(true);
sym->setMaterial(mCurrentSettings->clone());
QgsVectorLayer3DRenderer *pcR = new QgsVectorLayer3DRenderer
(sym->clone());
pcLyr->setRenderer3D(pcR);
}
Can any one help us in this regard?
Regards
Raghunath
