// Get the first node of a graph
InstantTerra instantTerra = CreateInstantTerra();
Project project = instantTerra.GetProject();

Node firstNode = graph.GetNode(0);
Connector firstConnector = firstNode.GetConnector(0);

Data data = firstNode.GetData(firstConnector);
DataType Data::GetType()

Returns the type of data.

int Data::GetWidth()

Returns Terrain / Mask / Color map / Vector map width.

Throws

Error – If the data is not of the type [Terrain, Mask, ColorMap, VectorMap], the following error code will be reported ErrorCode::DataIsNotAGrid.

int Data::GetHeight()

Returns Terrain / Mask / Color map / Vector map height.

Throws

Error – If the data is not of the type [Terrain, Mask, ColorMap, VectorMap], the following error code will be reported ErrorCode::DataIsNotAGrid.

void Data::GetFloatContent(float *buffer, int bufferSize, int startingX, int startingY, int width, int height, int resolution)

Returns, in a float buffer, the content of the terrain or mask.

Warning

The size of the buffer should be superior or egal to width * height * sizeof(float).

Values startingX and startingY are the top left point coordinates of the part you want to get.

  • 0: Full resolution

  • 1: Half resolution

  • 2: Quarter resolution

  • …
