Wind arrows can be animated and shown at multiple levels. Arrows can also be
made transparent. The terrain can be shown as texture drape or as a simple height
color surface.

VRMenu consists of two tab panels, allowing the shape of the visualized component to
be adjusted via the intensity slider.

Wireframe rendering can be toggled using a button in the panel. The size of the arrow
glyph can be adjusted via a slider in the user interface.

Simluation of Fuel Injection Spray

A 3D grid of space shows residual engine combustion chemical species from a fuel
injection numerical equivalent. The analysis was performed using KIVA, a CFD
combustion simulator.

Multiple Texture Slice Planes

A14MB binary volume of seismic exploration data is shown as a 3D model. A series of
slice planes are used to reveal the interior structure. Each plane is 'textured' to show
the high-resolution data.

Heat Convection in an Enclosed Room

The wireframe outline shows a room with a table and other small objects. A heat source
in one corner causes convective flow inside the room. A series of stream ribbons
and spheres show how "bubbles" would move when following the convective air current.

Small Molecule Network- CRAMBIN

A simple 4- molecule network shows how AVS/Express can be used to visualize a
molecular strucutre, showing bonds and atom positions. Bonds and atoms can be
hidden or shown, and the atom spheres can be made transparent. Bond cylinder width
is also adjustable.

Particle Animation within a Mixing Vessel

A 3D unstructured mesh contains flow field data in this industrial mixing vessel. Two
different liquids flow in the chamber from the inlet pipes, mix in a spiral flow, and exit at
the bottom.

Small particles are injected at regular intervals to create a visible animation of flow
fields.

Salt Dome Geological Model with Interpreted features
Data courtesy of the Society of Exploration Geophysicists (SEG)

A series of surfaces are shown in a 3D domain, representing basins (horizons) or
vertical faults. The cap of salt dome is visible in the center. Surface Vsibility can be
toggled via menu command.

The flies are read directly from GOCAD format. Global transparency can be applied to the
scene to allow visibility through various levels.

All data is simulated using modification of the Kutta-Joukowski method. The simulation
is interactive with respect to three variables: wing span of the finite wing, angle of
attack of the wing, and the number of grid points in the solution space. Modifying these
variables causes the simulation to be rerun. Vorticity magnitude is calculated and
shown on a slice plane projected on the floor of the space.

A complex geological model of an oil reservoir is shown using a texture-map color
system. Using the Eclipse oil reservoir simulation, oil saturation is shown with high
saturation in red, low in blue. A series of vertical faults in the model is visible from
certain perspectives. The yellow-green transition region in the center forms intersecting
shapes through the structure. The scalar 2 texture module can be replaced with isoline
or solid contour modules fro different and interesting views if this data.

VRMenu consists of two tab panels, allowing the shape of the visualized component to
be adjusted via the intensity slider.

Wireframe rendering can be toggled using a button in the panel. The size of the arrow

3D Electron Density Ball

This is a 3D field with isosurface, several cut planes with iso-contour lines, and a solid
contour surface. Visibility, transparency and isosurface threshold value can be varied.

NOTE: The original image was on the January cover of Science and was created by Tom
Palmer of Cray Research. The electron distribution image is a snapshot from a quantum
molecular dynamics supercomputer simulation of a solid C60 at 1000 K.

Wind Around City Skyscrapers
Data courtesy of KGt Inc., and AdamNet Inc., Japan

A 3D surface showing two skyscrapers forms the base area for the demo. The 3D space
around the buildings contains wind velocity vector information. The stream-ribbon
technique shows the divergence of the wind pattern around one of the buildings. An
optional solid contour surface can be added to show color-coded wind speed.
Individual ribbons can be selected and traslated to different seed positions.

FEA stress results are shown on the unstructured grid. User external faces, isolines
and solid contours with thresholding.

Wand manipulation is supported via the WandUViewer3D module available in
AVS/Express Mulitpipe Edition. The viewer works in both OpenGL and MPE
renderers.

A full 3D external airflow model of an aircraft is shown. Various Visualization techniques
are used to show the flow field, such as bounds, isosurface, streamlines and advector.

This is a structured 3D field with a curvilinear grid. The first orthoslice tool or the show
mesh feature can be used to show the aircraft skin. The 3D field around the aircraft is
modeled using a structured body-fitting coordinate scheme.
