  More blobscape fun. (Message 1 to 9 of 9)

I've made some more changes to my blobscape macro.  Here's
the format:

blobscape(X, Y, Strength, Radius, MaxHeight, Seed, Momentum)

which creates a blobscape from an X by Y array, where each sphere
has Strength and Radius values, MaxHeight is the max amount of
change in height from one element to the next, seed is a random
seed for the random parts, and momentum basically determines
whether slopes are more often positive or negative.

In the first image, the code is:

    blobscape(10, 10, 2, 2.25, 1, 6548, 0.8)

In the second:

   blobscape(10, 10, 2, 2.25, 10, 6548, 0.8)

In the third:

   blobscape(10, 10, 2, 0.1, 10, 6548, 0.8)

(I hope the images show...)

That looks very good, but still isosurfaces seem more efficient to me.  You have
more control over the fine structure then (you seem to use a normal for that). 
Furthermore it's much easier to synchronize shape and texturing.  

Anyway i hope you publish the code when you finished it.  

BTW, what's the rendering time/memory use for these ?

I kinda like it. How 'bout posting the source for your macro? Please?

I would love to see a simple animation of the second image, with the camera
spinning around it and the blob size slowly decreasing to zero and maybe
even have the  blobs slowly separate...
should look like the object is dissolving in thin air....

These look really good, too. They could make some cool rock formations.

Nice. What's the render time for these? Do you bound?

Pretty heavy jpgs btw.

Nice...
Try :
1. various similar shapes making a wall
2. a 'grand canyon' of this shape...?
3. ??? pebble beach...???

I will!

Around 4 minutes each, at 640x480 with aa.

No bounding, although that might not be a bad idea.  At 640x480
with aa they took about 4 minutes to render.
