Entity that handles the exporting of 3D scene.
A class to represent a 2D point.
Definition: qgspointxy.h:59
Polygon geometry type.

void setPolygons(const QList< QgsPolygon * > &polygons, const QList< QgsFeatureId > &featureIds, const QgsPointXY &origin, float extrusionHeight, const QList< float > &extrusionHeightPerPolygon=QList< float >())
Initializes vertex buffer from given polygons. Takes ownership of passed polygon geometries.
void setInvertNormals(bool invert)
Sets whether the normals of triangles will be inverted (useful for fixing clockwise / counter-clockwi...
QgsFeatureId triangleIndexToFeatureId(uint triangleIndex) const
Returns ID of the feature to which given triangle index belongs (used for picking).
QgsTessellatedPolygonGeometry(bool _withNormals=true, bool invertNormals=false, bool addBackFaces=false, bool addTextureCoords=false, QNode *parent=nullptr)
Constructor.
bool addBackFaces() const
Returns whether also triangles facing the other side will be created.
void setData(const QByteArray &vertexBufferData, int vertexCount, const QVector< QgsFeatureId > &triangleIndexFids, const QVector< uint > &triangleIndexStartingIndices)
Initializes vertex buffer (and other members) from data that were already tessellated.
void setAddBackFaces(bool add)
Sets whether also triangles facing the other side will be created.
void setAddTextureCoords(bool add)
Sets whether the texture coordinates will be generated.
