The "Fuzz" texture appears to be ANOTHER one of those
undocumented Imagine features. Anyway, I've done some experimentation
with the "Fuzz" texture, here's what I know.
Fuzz - Basic features:
It's a "Space Filling" (Impulse terminology) noise type texture.
That is, the texture changes along all three axis.
In its most basic form (equal X, Y, Z sizes and low magnitude
and velocity noise values), it produces fuzzy globules (approximately
spherical masses).
Space between the fuzzy globules shows underlying textures and
attributes on the object.
The texture axis orientation (relative to the object) is not
particularly important.
Fuzz - parameters:
X, Y, and Z sizes: determines size of the fuzzy globules;
Noise 1 & 2 mag/vel: determines how disturbed the fuzzy globules
become (functions similar to other Imagine noise
type textures);
Dispersion: determines the number of fuzzy globules;
Fuzz clip: appears to affect the spacing of the fuzzy
globules;
Fuzz R, G, B color: determines the color of the fuzzy globules;
Fil./Refl. adjust: sets the filter and reflect attributes of the
fuzzy globules;
Fuzz - General observations:
Increasing the clip value (0.9 - 1.0) can result in overlapping
globules with unpredictable results.
Decreasing the clip value to 0 results in zero globules.
The default parameter values produce a nice "TV Static"
appearance.
Higher magnitude/velocity values result in a wispy smoke type of
appearance (see sample parameter values below) similar to that achieved
using the CLRNOIZ texture.
Intermediate magnitude values, low velocity values and
repetitively applying the texture can produce a scattered cumulus cloud
pattern with the appearance of depth (see below).
Wispy Smoke (a la fuzz):
- Add a default plane.
- Set the object color to 0, 0, 0. Make it bright.
- Adjust the perspective zoom control (Z) such that the plane takes
up most of the view.
- Apply the FUZZ texture (using the following parameter values)
and quickrender:
Column One Two
____ ____
30 0.4
30 100
100 100
0.6 100
2.8 0
5.8 0
0.3 0
0.7 0
Scattered Cumulus Clouds (a la fuzz):
- Add a ground plane.
- Set the color to 135, 206, 235. Make it bright.
- Adjust the perspective angle (A) view such that it looks straight
down on the ground plane. Set the zoom ratio (Display menu,
Perspective, Zoom ratio) to 0.3.
- Repetitively apply the FUZZ texture to the ground plane (4 times)
using the following parameter values:
Apply the FUZZ texture (priority 1) as follows:
Column One Two
____ ____
1000 0.5
1000 245
1000 245
