Manages the data of each object of the scene (positions, normals, texture coordinates ....
void setMaterialParameter(const QString &parameter, const QString &value)
Sets a material parameter to be exported in the .mtl file.
QImage textureImage()
Returns the texture image used by the object.
void setType(ObjectType type)
Sets the object type.
Qgs3DExportObject(const QString &name)
Qgs3DExportObject Constructs an export object that will be filled with coordinates later.
ObjectType type() const
Returns the object type.
ObjectType
The type of exported geometry.
QString name() const
Returns the object name.
void setTextureImage(const QImage &image)
Sets the texture image used by the object.
bool smoothEdges()
Returns whether object edges will look smooth.
void setName(const QString &name)
Sets the object name.
void setSmoothEdges(bool smoothEdges)
Sets whether triangles edges will look smooth.
@ Points
Point based rendering, requires point data.
