Hi friends,
I must first admit that I am NOT knowledgeable enough about
internals of 3D engines. I have just read the 2 books of Keith Peters
about 3D and some chapters regarding maths underlying the 3D
operations.
I have been following both Papervision3D and Away3D since a year or
so. Now I have got a project to work on some interesting 3D model
manipulation. I do not know 3d modelling. I had been using swift3d
papervision exporter to export DAe and was using papervision. However
for larger models I found that Papervision 3D sucks. I was knowing
that Away3D had moved way forward and implemented normal mapping and
DOT3BitmapMaterial. From my premitive knowledge of 3D, I am thinking
that this is what is going to save me by creating low poly models and
high quality normal maps. I have also seen the demo of "2 heads" and
"teapot" given by Fabrice. However, he has not shared the source code
(or I couldn't find it probably).
I am giving below the stuff where I am stuck.
The 3d model is of a female model (Masha):

the model rendered using swift3d (papervision exporter)
http://www.dnyandeep.com/headTest/swift/head.zip
Same DAE as is used by PV3D is being used in below given Away3D test
http://www.dnyandeep.com/headTest/AwayNormalMapTest.html
You can notice that Away3D had incorrectly rendered the same model.
However pv3d does correctly. I really want to use Away3d for this
project because of its efficiency and especially what I read about
occlusion culling that is available in Away3D.
I am stuck, any pointers where I am going wrong? Also I wish to know
perfect guidelines about what I need to do to directly export the
model from 3D tools like Max. Can somebody guide me please? As I will
need to tell this to the 3D modeller person I am working with to get
the exported 3DS/DAE files from him in perfect format suitable to
Away3D. Also why the model is getting rendered is PV3D but not doing
correctly in Away? I definitely do not know any internals, so any help
is appreciated.
