vlpick_iso_color

NAME

vlpick_iso_color - Choose the color of the isosurface from the color map of the specified variable

SYNOPSIS

#include <parvox.h>

void vlpick_iso_color(vlvariable *variable, float threshold, vlcolor *color)

DESCRIPTION

vlpick_iso_color() picks the color of the isosurface defined by threshold for a given variable from its pre-defined colormap. The color of the isosurface is returned to the vlcolor data structure pointed by color. ParVox supports multiple isosurface rendering; each surface is represented by a different color. The color of the surface can be chosen by the user by filling up the vlsurface (defined in vltypes.h) data structure with the selected color before calling vliso_surface() or vliso_shade(); or it can be selected from a predefined colormap set by vlset_colormap(). The colormap is used to map the variable values to colors in direct volume rendering. By mapping the isosurface color with the direct volume color, it is easy to correlate one type of rendered image to the other. xmparvox allows users to either enter the isosurface's color or use the colormap color.
