The Qgis class provides global constants for use throughout the application.
Definition qgis.h:54
AltitudeClamping
Altitude clamping.
Definition qgis.h:3691
@ Relative
Elevation is relative to terrain height (final elevation = terrain elevation + feature elevation)
CullingMode
Triangle culling mode.
Definition qgs3dtypes.h:36
@ NoCulling
Will render both front and back faces of triangles.
Definition qgs3dtypes.h:37
virtual QgsAbstract3DSymbol * clone() const =0
Returns a new instance of the symbol with the same settings.
A ramp shader will color a raster pixel based on a list of values ranges in a ramp.
ZValueType
How to render the Z value of the mesh.
void setAddBackFaces(bool add)
Sets whether also triangles facing the other side will be created.
QString type() const override
Returns identifier of symbol type. Each 3D symbol implementation should return a different type.
void setHeight(float height)
Sets height (altitude) of the symbol (in map units)
bool addBackFaces() const
Returns whether also triangles facing the other side will be created.
void setAltitudeClamping(Qgis::AltitudeClamping altClamping)
Sets method that determines altitude (whether to clamp to feature to terrain)
float height() const
Returns height (altitude) of the symbol (in map units)
~QgsMesh3DSymbol() override
RenderingStyle
How to render the color of the mesh.
@ ColorRamp
Render the mesh with a color ramp.
@ SingleColor
Render the mesh with a single color.
The class is used as a container of context for various read/write operations on other objects.
