copyVectorSymbolMaterial()

bool Qgs3DSymbolUtils::copyVectorSymbolMaterial ( const QgsAbstract3DSymbol * fromSymbol, QgsAbstract3DSymbol * toSymbol )

static

Copies the material properties of a vector 3D symbol from one symbol to another.

Parameters

fromSymbol	Source 3D symbol from which the material properties are copied.
toSymbol	Destination 3D symbol to which the material properties are applied.

Returns

true if the material properties were successfully copied, false otherwise.

Definition at line 248 of file qgs3dsymbolutils.cpp.

setVectorSymbolBaseColor()

bool Qgs3DSymbolUtils::setVectorSymbolBaseColor ( QgsAbstract3DSymbol * symbol, const QColor & baseColor )

static

Sets the base color of the material settings associated with a 3D vector symbol.

Parameters

symbol	3D symbol whose material settings will be modified.
baseColor	Base color to apply to the symbol's material settings.

Returns

true if the material's base color was successfully set, false otherwise.

Definition at line 226 of file qgs3dsymbolutils.cpp.

vectorSymbolAverageColor()

QColor Qgs3DSymbolUtils::vectorSymbolAverageColor ( const QgsAbstract3DSymbol * symbol )

static

Computes an approximate color from a 3D vector symbol.

Extracts a representative color from the symbol's material settings, accounting for its specific shading model (Phong, Gooch, etc.).

Parameters

symbol

The 3D symbol to extract the color from.

Returns

A QColor representing the symbol's average appearance, or a default color if the symbol type is not supported.

vectorSymbolPreviewIcon()

QIcon Qgs3DSymbolUtils::vectorSymbolPreviewIcon ( const QgsAbstract3DSymbol * symbol, const QSize & size, const QgsScreenProperties & screen, int padding )

static

Returns an icon preview for a 3D vector symbol.

Parameters

symbol	3D symbol to generate the preview for.
size	Target pixmap size.
screen	Destination screen properties used to determine DPI and device pixel ratio.
padding	Space between icon edge and symbol.

Returns

An icon containing a preview of the symbol.

Note

For line and circle symbols, the size of the drawn icon depends on the symbol's parameters.
