Member Function Documentation

void vtElevLayer::DetermineMeterSpacing ( )

Determine the approximate spacing, in meters, between each grid cell, in the X direction. The result is placed in the m_fSpacing member for use in shading.

bool vtElevLayer::HasData ( )

If an elevation layer is waiting to be paged in, then it has some basic information like extents, but no data yet.

bool vtElevLayer::ImportFromDB	(	const char *	szFileName,
		bool	progress_callbackint
	)

Loads from a "DB" file, which is the format of libMini tilesets tiles.

Returns: true if the file was successfully opened and read.

The documentation for this class was generated from the following files:
