I've a problem (certainly easy) that I cannot solve.
I work on a perfly-based application. I've different textured objects
in a scene, and I want to add an axis system with one color by axis.
I can see the colors only if I turn the lighting off.
Does it exist a parameter so that my lines (witch should be green, blue
and red) doesn't appear in white ? (it doesn't seem to be a highlighting
problem)
Thanks for help

PS : here's my code :
// coordinate system
axisX = new pfGeoSet();
axisY = new pfGeoSet();
axisZ = new pfGeoSet();
/* Define the type of pfGeoSet */
axisX->setPrimType(PFGS_LINES);
axisY->setPrimType(PFGS_LINES);
axisZ->setPrimType(PFGS_LINES);
/* Set the coord of the lines */
axisX->setAttr(PFGS_COORD3, PFGS_PER_VERTEX, axisXcoord, NULL);
axisY->setAttr(PFGS_COORD3, PFGS_PER_VERTEX, axisYcoord, NULL);
axisZ->setAttr(PFGS_COORD3, PFGS_PER_VERTEX, axisZcoord, NULL);
/* Set the color of the lines */
axisX->setAttr(PFGS_COLOR4, PFGS_PER_VERTEX, axisXColor, NULL);
axisY->setAttr(PFGS_COLOR4, PFGS_PER_VERTEX, axisYColor, NULL);
axisZ->setAttr(PFGS_COLOR4, PFGS_PER_VERTEX, axisZColor, NULL);
/* Set the number of lines in the pfGeoSet */
axisX->setNumPrims(1);
axisY->setNumPrims(1);
axisZ->setNumPrims(1);
char buf1[16];
sprintf(buf1, "coordSysObject\0");
coordSys = new pfGeode;
coordSys->addGSet(axisX);
coordSys->addGSet(axisY);
coordSys->addGSet(axisZ);
coordSys->setName (buf1);
char buf2[15];
sprintf(buf2, "coordSysCoord\0");
coordSysDCS = new pfDCS;
coordSysDCS->addChild (coordSys);
coordSysDCS->setName(buf2);
