Description
The TEXT TO GEOM module creates a geometry of the input string based upon
the AVS standard set of geometry label controls.
Inputs
input string string for which a label geometry is generated
Outputs
geom_output label geometry output
Parameters
x ref point
y ref point
z ref point reference point for the label in screen space
(-1,-1,-1) to (1,1,1) for title strings; reference
point is in the same coordinate system as the other
elements in the geometry viewer for non-title strings
x offset
y offset
z offset offset values in screen space applied after the
reference point is set (or transformed for non-title
strings)
height height of the selected font for the label
red red component of the label color
green green component of the label color
blue blue component of the label color
font AVS font number in the range of 1-21
background rectangle toggle indicating if the background rectangle that
encloses the text should be drawn
title string toggle indicating whether string is considered a
window title with screen space coordinates or a
non-title string with coordinates to match other
elements of the geometry viewer
drop shadow toggle indicating if a one-pixel drop-shadow highlight
should be added to the text
alignment choice of LEFT, CENTER, RIGHT for specifying the
position of the reference point within the label

Limitations
This function is needed only for AVS 4.0. The standard AVS Data Input
module "label" can be used for AVS 5.0 systems.

-------------------------------------------------------------------------
The MCNC Environmental Programs Group has created this module as part of a
suite of AVS demo modules, networks, and sample data sets to demonstrate
the functionality of its visualization prototype for an Environmental
Decision Support System (EDSS). This system provides a unified method of
analysis and visualization for data output from different environmental air
quality models. Remotely, standard output files from the following models
can be read into AVS:
ROM (Regional Oxidant Model)
RADM (Regional Acid Deposition Model), low res and high res
RADM (Regional Acid Depostion Model) Emissions, low res
UAM (Urban Airshed Model, regulatory version)
UAM (Urban Airshed Model, AREAL research version)
UAM Wind (Urban Airshed Model, regulatory version)
MCNC ALPHA-Prototype netCDF files
Alternatively, xdr portable binary AVS fields can be created from these
data types and accessed directly from the local workstation.
You can download these modules individually from the IAC using anonymous
ftp to the appropriate directories /avs_modules at avs.ncsc.org.
If you would like to download the entire suite of modules, networks, and
sample datasets at the same time, the IAC recommends that you use
anonymous ftp to grab the following file from avs.ncsc.org -
/sample_data/avs_data/MCNC_Env_Pgms/MCNC_Env_Pgms.tar.Z
This contains all source code to all local and remote modules, as well as
all of the sample datasets, networks, documentation, installation, and
usage notes.
