NAME

cdf_display_data_writer - write display data to netCDF file.

DESCRIPTION

The cdf_display_data_writer takes as input a display_data object or filter, and writes the data out to a netCDF file. If the data is time variant, the data between the start time and end time will be written.

SUPERCLASS

data_writer

INSTANCE VARIABLES

data_in then name of a display_filter or display_data object. Provides the display_data to write out.

filename the name of the netCDF file to write. By default, filename="display_data.cdf".

points boolean to control whether points are written. By default, points=1.0 and points are written.

lines boolean to control whether lines are written. By default, lines=1.0 and lines are written.

polygons boolean to control whether polygons are written. By default, polygons=1.0 and polygons are written.

triangle_strips boolean to control whether triangle strips are written. By default, triangle_strips=1.0 and triangle strips are written.

scalars boolean to control whether scalars are written. By default, scalars=1.0 and scalars are written.

vectors boolean to control whether vectors are written. By default, vectors=1.0 and vectors are written.

normals boolean to control whether normals are written. By default, normals=1.0 and normals are written.

texture_coords boolean to control whether texture coordinates are written. By default, texture_coords=1.0 and texture coordinates are written.

clobber boolean to control whether netCDF file can be overwritten or not. By default clobber=1 and the netCDF file is overwritten.
