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).
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.
