Hi Experts,
I am experimenting with normal maps regarding on of our
requirements. I have the normal map and have done tests for few other
modes of rendering. I am giving the links below. Everything except the
normal map material is working well. I am giving the links below:

http://www.dnyandeep.com/demos/3d/away-test/head/ShadingColorMaterial.html
http://www.dnyandeep.com/demos/3d/away-test/head/Dot3BitmapMaterial.html
http://www.dnyandeep.com/demos/3d/away-test/head/Dot3BitmapMaterialF10.html
I have set
Dot3BitmapMaterialF10(demoMat).showNormals = true;
for the 4th link just to see that the model is there and faces are
getting rendered.
I am not sure why the normal map demo is not working. I have used the
bitmap from away3d torso demonstration. The normal map can be seen
at:
http://www.dnyandeep.com/demos/3d/away-test/head/assets/normal-map.jpg
However the normal map is embedded in the demo swf file.
The relatively high-poly model used to generate the normal map can be
found in the source given at below specified link.
I have uploaded the entire source at:
http://www.dnyandeep.com/demos/3d/away-test/head/head-src.zip
Any thoughts on why this is not working would be highly appreciated.
2) Also, I tried nVidia Melody tool to generate normal map. You can
find the source that it generated 2 files
lp.OSNM.dds - probably object space normal map
lp.TSNM.dds - probably tangent space normal map
I guess this from shortform they are using, not sure if it is true.
However, I find pretty strange thing that the maps are having dds
extensions which I do not know what is. Secondly, these formats are
associated on my machine with 3D polygon cruncher. When it opens the
files, it show highly divided strange graphic. Though, The RGB
coloured picture gives an indication of itself being a normal map, it
is very weird and different than the one generated using 3DSMax/
Prefab. Any pointers on this would be great too!
Sincerely,
Sushant
