Extend the code to 3D, add test or example code. Clients are now able to easily and quickly retrieve large datasets which previously would have taken Matlab much longer to process the request and parse the results. 325-432. This will open a GUI to select the file to import the color scheme from. Due to the lesser testing of the OpenCL code, it currently only supports a single gas species while the Python code supports two species.
