View options
Facets shading color: Clicking the select button displays a standard dialog for the selection of
the pre-set facet color. The defined facet color is used to colorize imported facets without color
information of their own.
Slice shading color: Clicking the select button displays a standard dialog for the selection of the
slice shading color. The slice shading color is used within the Slice representation to shade the
side surfaces of the contours.
OpenGL parameters
Define the properties for controlling the graphic hardware using the 3D Interface OpenGL.
Real Time interaction: Defines if the geometry is displayed during interaction or if it is replaced
by a simpler representation. If real time interaction is disabled, a wire lattice cube is displayed
instead of the model during interactive rotation, zoom and translation.
Use display lists memory: Stores graphic data in the memory of the graphic controller. If
deactivated, all triangles are transferred to the display adapter with each display update. If
activated, graphic data is stored directly in the graphic memory and it need not be exported
again, for example for a rotation of the view.
Use hardware accelerator: Switches between hardware accelerated and solely software
accelerated 3D graphic display. For hardware accelerated view the OpenGL driver of the graphic
card chip producer is used. If hardware acceleration is deactivated, the solely software based
Windows OpenGL-driver is used. But the hardware acceleration should always be enabled for
performance reasons.
INFO: VisCAM optimizes the access to the graphic interface OpenGL so that the highest possible
graphic performance is achieved. At this, only optimizations according to the official OpenGL
specification 1.2 are used. Graphic problems may occur in case of errors in the OpenGL driver or
errors in the storage management of the graphic card producer. Rarely, this may even result in
system crashes.
In such cases, you should at first try to solve the problem by an updated driver version of the
graphic card or graphic chip producer. If correct display using hardware acceleration is not
possible although the current driver is installed, the graphic problems may be solved by
deactivating certain options (Use display list memory,Display backward triangles). If this still
does not solve the graphic problems, it is recommended to deactivate hardware acceleration.
However, this is expected to result in slower graphical display.
Facets parameters
Display backward triangles: If this function is enabled, triangles whose exterior sides show away
from the viewer are displayed (facet representation). If the display of the reverse sides of the
triangles is deactivated the number of triangles to be displayed is reduced, but the interior of a
model is not displayed then. However, it may be helpful to display the interior if the model is not
closed.
Display surface borders: If this function is enabled, black lines are drawn on the facet model to
border several surfaces. The surface detection depends on the parameters for facet surfaces.
See Surface option in Manipulate Surface of the Facets menu to adjust these values.
Show unmatched edges: If this option is enabled,unmatched edges are drawn highlighted as
soon as they are detected.
Show flipped triangles: If this option is enabled, back facing triangles are drawn red shaded.
