Subdivision + displacement test

New features look great. I remain optimistic about how this will work out in any Blender exporter. There is only so much one can do with a python script. Maybe Blender 2.50 will give exporter developers more control.

I don't mean to say Blender does not give us enough options, the best way to integrate into Blender is probably a custom build, rather than a python script. I think that involves much more commitment than anyone is willing and able to offer, though.

i dont mind the exporter at all. its probably one of the easiest exporters to use. the one for Blender, that is. duno about the other ones!

Another test.

How long did it takes to generate the model? And how much ram does it consume?

Wow !
It's simply outstanding !

Well, the actual subdivision is pretty fast currently, perhaps 20 secs. Building the kd-tree took about 60 secs.
After the build stage, Indigo was using about 300 MB RAM.
There's 2.5M triangles there.

This is way too cool

cool O.o

how many tris/pixel?

An unbiased Terragen!
I take it the triangles are not smoothed here either, are they? Any idea how the Maxwell guys do such smooth displacement?

BbB:
normal smoothing was disabled for that render, you can turn it on tho.

Oh. So you've solved that one?

Well, it's simple enough to recalculate shading normals after subdivision and/or displacement.
What I was talking about earlier was trying to make shading normals unnecessary by sufficient subdivision.

Oops, sorry.
(you know, I REALLY am no getting any sleep right now!)

Would that be sub-supersamplesized-tris? O.o

Lovely stuff I'm seeing here I'm impressed Nick!
