- _m_v_i_e_w Is a demo of rendering methods useful for drawing molecules. Both
- atoms and bond structures are drawn. _m_v_i_e_w uses the sphere primitive of
- the Sphere Library for drawing the atoms. Various graphics features,
- such as accumulation buffer, line antialiasing, real-time, full scene
- multisampled antialiasing, and stereo in a window are configurable via a
- graphical control panel.
-
- When invoked without arguments, _m_v_i_e_w looks for data files in the current
- directory and in /usr/demos/General_Demos/mview/data. _m_v_i_e_w -_I _d_i_r_n_a_m_e
- will add the directory _d_i_r_n_a_m_e to the list of directories to search for
- models. _m_v_i_e_w -_n _m_o_l__n_a_m_e will cause the program to start up displaying
- the named molecule.
-
-
- Pressing the ESC key exits the program.
-
-
- The following describes the functionality of each mouse button.
-
- Middle - Rotate the model objects about its center.
- Left - Scale the model objects.
- Left+Middle+Right - Translate the model objects in the z plane.
- Left+Middle - Zoom in or out.
-
- The following describes the functionality of each button
- in the control panel.
-
- Help - Click the help button to exit this window.
- Model - Scroll through the different
- available molecular models.
- Reset - Reset the model objects to their original size,
- and put the point of view back in its
- original position. If the objects are rotating,
- pressing the Reset button will stop them.
- Quit - Quit the program.
- Bitmap Spheres - Use the hw bitmapped sphere primitive (RealityEngine only)
- Sphere Depth - Click the left mouse to decrease the
- tessellation depth level.
- Click the middle mouse to increase the
- tessellation depth level.
- The depth range is 1 through 30 inclusively.
- Sphere Prim - Scroll through the different display
- primitive options. The options are:
- mesh, polygon, line, and point.
- Sphere Type - Scroll through the different sphere

- tessellation types. The options are:
- oct, icos, bary, cube, and bilin.
- Depthcue - Toggle depth-cue mode on/off.
- Projection - Select orthographic or perspective projection.
- Orient - Toggle orient mode on/off.
- When on, the sphere is displayed in a fixed
- orientation independent of world rotations.
- Hemi Sphere - Toggle hemi sphere mode on/off.
- Draw Quick - Toggle Quick drawing on/off.
- In quick-draw mode no antialiasing or
- accumulation processes are done.
- Display Bonds - Toggle the display of the bonds on/off.
- Display Atoms - Toggle the display of the atoms on/off.
- Accumulate Atoms - Toggle the accumulation of the atoms on/off.
- In this mode, successive full scene
- antialiasing is done. When the objects stop
- moving, the static image is accumulated in the
- accumulation buffer with slight perturbations.
- The way the perturbations of the atoms are
- done is controlled by roll mode and spin mode.
- The final image is antialiased.
- Smooth Bonds - Scroll through the different line smooth
- levels. The different levels are:
- off, on, and smoother.
- End Correct Bonds - Toggle the End Correct mode on/off.
- In end correct mode the end point of the bonds
- are antialiased. This is visible only if
- the atoms are not displayed.
- Accumulate Bonds - Toggle the accumulation of the bonds on/off.
- This is an alternative way for displaying
- smooth lines.
- Radius - Use the left mouse button to change
- the relative size of the atom radii while
- dragging the vertical bar.
- Multisample - This will toggle real-time, full scene
- multisampled antialiasing
- on a suitable RealityEngine configuration.
- Stereo - This will toggle in-the-window stereo on
- a suitable RealityEngine configuration
- with the proper monitor configuration
- (setmon 960x680_108s).
-
- The Following Keys have useful functionality:
-
- O/L - Will increase/decrease, respectively,
- the separation for each eye when in stereo.
