I would like to see the effect of a spot light in perfly with a .iv file like :
<<<<<<<
#Inventor V2.0 ascii
Separator {
SpotLight {
color 1 0 0
location 0 0 5
direction 0 0 -1
cutOffAngle 0.15
}
Group {
NormalBinding {
value OVERALL
}
Coordinate3 {
point [ -1 -1 0,
0 -1 0,
1 -1 0,
-1 0 0,
0 0 0,
1 0 0,
-1 1 0,
0 1 0,
1 1 0 ]
}
IndexedFaceSet {
coordIndex [ 0, 1, 4, 3, -1, 1, 2, 5,
4, -1, 3, 4, 7, 6, -1, 4,
5, 8, 7, -1 ]
}
}
}
>>>>>>>
1) I tried perfly with no retessalation (-o 4), local lighting (-O 5) and
inventor lights conversion (-y iv,2,1), so ...
perfly -o 4 -O 5 -y iv,2,1 file.iv
... and the light has no effect on my polygons. Why ?
2) I changed the normal binding OVERALL to PER_VERTEX_INDEXED and I added a
normalIndex field in the indexedFaceSet ( normalIndex [ 0, 0, 0, 0, -1, 0, 0,
0, 0, -1, 0, 0, 0, 0, -1, 0, 0, 0, 0, -1 ]) ...
... and my polygons are red and flat shaded. Why ?
3) Is there a way to see a correct interpolated effect on my polygons ?
Thanks,
Lionel
