Hi,
The following code behaves differently on a Indigo ELAN
and a 320VGX:
lmbind( ..wawawa ) /* switch lighting (lights,model,material) on */
lmcolor( LMC_AD );
..draw lighted stuff..
.. c3f,n3f,v3f calls..
lmbind( LMODEL,0 ); /* disable lighting */
lmcolor( LMC_COLOR ); /* <- ?? */
..draw unlighted stuff..
.. c3f,v3f calls..
Now, the unlighted stuff gets drawn depressingly black on a ELAN,
if lmcolor( LMC_COLOR ) is not used.
The VGX behaviour is more similar to the man page:
"lmcolor mode is significant only while lighting is on".
Bug, feature, or my bloody ignorance of something obvious ?
if( FAQ ) printf("our news server went offline for some weeks.sorry\n");
TIA
Peter
