  Civilization of sorts, or, Fun with crackle (Message 1 to 20 of 20)

Sort of, not really, based on Incan, Aztec, and Mayan stuff.  Every
object but the cloud pigment on the sky_sphere, which is not discernably
reflected in the brass spheres anyway, uses crackle.  Also my first use
of rad_def.inc in 3.5, and I was quite pleased.

The surface normals got averaged out a bit when I resized it from
1280x960.  The stonework looks less precise than I wanted, but I
increased the beveling in the normal to make the cracks more visible. 
Everything looks better at 1280x960.

Comments?

Strange but nice... perhaps the sun is too vertical (if there were not 
spheres, sun position will be very difficult to understand).

An excellent image with a sense of the ancient - perhaps less perfection,
some ruination? Nice colour and textures.

I really like this although I agree with Jaime that the sun is too vertical.
Try lowering it towards the horizon and then you should be able to see a
more dramatic effect from the radiosity.

Really effective, the crackle pattern offers indeed a lot of
possibilities.  Is it a heightfield or an isosurface?

perhaps... i might try some different positions.

Thanks.  More ruination might be difficult though, I might have to go to
an isosurface, and then, the displacement is vertical so it'd be hard to
take chunks out perpendicular to the inclined faces without skewing the
chunks.  If I want to wait years I can always difference two isos.

Thanks.  I agree, a little more contrast might help it.

Height_field.  Isosurface goes much much slower.  :(

Lowered the sun's position and tweaked the surface normals a bit.  The
blue/yellow contrast from the radiosity is more pronounced now.  Perhaps
a bit dark now though, could be adjusted.

Much better, but I still think it should be lower. At this angle you get a
bad line diagonally through the center of the image where you can just see
the shadow which is kind of distarcting.

(mumble mumble groan) Though, perhaps you are right...

The chipped stone looks good.  What occured to me about the vines, or
vegetation, is that there isn't any thick ground cover on the lowest flat
areas.  Guess that could be explained by the predominant places for growth
being only on angled walls.  Would be great if there were a way to get the
smaller walls to have less greenery and the larger ones more.  Not sure if
slope texturing can vary in that way.

I don't think that's possible.  Also, to get better contrast between the
vegetation in the high and low flat areas, I had to make the texture
depend to much on elevation and too little on slope, and couldn't get
realistic contrast between the walls and the flat areas.  I decided this
was an okay compromise.

Maybe I could have a look into combining two vine textures, one more
dependent on elevation and one more on slope.

Is there any chance I could get a copy of the code for that Christmas
tree in your gallery? I tried to replicate it, but very weird things
started to happen, so I abandoned that pretty fast...
