GRAPHICS: System kernel containing functions for initialization, scaling, color system, graphics contexts, drawing primitives, and hardcopy rendering.

AXES: Advanced axis modeling system supporting a wide range of 2D and 3D axis types including linear, logarithmic, polar, power, date/time, and user labeled axes.

BLOCKS: 3D irregular data and volume data display as 3D and 4D block diagrams. Support for undefined data values allows display of the data set interior.

CHARTS: Powerful 2D and 3D charting package for financial, engineering, and scientific charts with precise user control over all chart attributes. Includes functions for data interpolation.

CGM: Industry leading implementation of the ISO standard computer graphics metafile. CGM generator and interpreter supports all 3 metafile encodings. A built-in profile system ensures smooth metafile interchange.

CONTOURS: Color shaded contours, grids, and isolines in 2D, 3D, and 4D. Full user control of mesh interval, line attributes, isoline annotation, view angle, and legend.

CONTOURS+: Advanced contouring features, including isoline feathering, faults and barriers, regions, and user-defined grid spacing.

FLOWMAPS: Graphical display of multi-dimensional data represented by arrows, rose glyphs, or any symbol from the character library, with symbol mapping at minimum and maximum thresholds.

GRIDS: Functions for quick visual analysis of irregular and regular data as 2D scatter and grid displays, or 3D and 4D grid displays. Select average, minimum, or maximum value for shading multiple points in a cell.

IMAGE: Vertical and horizontal display of image data, real or integer, with no limits on number of colors. Provides optimal mapping to image, cell array, or rectangle drawing primitive on selected output device.

INTERPOLATIONS: Numerical methods for transforming scatter data into regular gridded data. Includes grid refinement and regridding functions.

PROJECTIONS: Data conversion between common cartographic projections using double precision arithmetic. Supports Azimuthal Stereographic, Gnomonic, Lambert Conformal Conic, Mercator, and UTM projections.

3D RENDER: Software rasterizer for displaying 3D geometry data as constant or Gouraud shaded objects with light source, or as wireframes. Useful for adding geometry to numerical data displays.

VOLUMES: Volume data rendering as isosurfaces, threshold volumes, or cutting planes. Includes 3D data interpolation methods.

SEISPLOT: Seismic data display as wiggle lines, variable area, and interpolated background charts. Complete user control of annotation including fill direction, trace interval, line attributes, and trace numbers.

CGM Seismic: Seismic industry extensions to CGM. Supports both CGM+ and CGM*PIP metafile formats.
