vlenable_surface, vldisable_surface
NAME
vlenable_surface, vldisable_surface - Enable
or disable a specific isosurface for the next rendering cycle.
SYNOPSIS
#include <parvox.h>
void vlenable_surface(vlvariable *variable,
int surface_id)
void vldisable_surface(vlvariable *variable,
int surface_id)
DESCRIPTION
vlenable_surface()
enables an isosurface with index surface_id
of a given variable
for the next rendering cycle. vldisable_surface() disables
the surface with surface_id for
the next rendering cycle.
ParVox allows maximal 8 surfaces defined for
each variable. The isosurface definitions are stored in an array
of data type vlsurface pointed by variable->isosurf
. By default, all
the isosurfaces are disabled when it is defined. Any of the defined
surfaces may be enabled or disabled from frame to frame.
Whenever the isosurface definition is changed, whether it is adding a new
surface, deleting an existing surface, enable/disable an existing surfaces,
or changing the existing surface definition, the entire volume has to be
reclassified by calling vliso_surface().
