SECTION 8 - Essence Settings and Other Attributes

17] Fun with Fuzz texture, By G. de Beaumont (Imagine 2.9 and higher)

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
         2     245
         0.1     0
         2       0
         0.1     0
         1       0

FUZZ texture (priority 2):

  Column One     Two
      1000       0.5          Axis position: 0, -40, 0
      1000     220
      1000     220
         2     220
         0.1     0
         2       0
         0.1     0
         1       0

FUZZ texture (priority 3):

  Column One     Two
       250       0.5
       250     245
       250     245
         2     245
         0.1     0
         2       0
         0.1     0
         0.6     0

FUZZ texture (priority 4):

  Column One     Two
       250       0.3
       250     215
       250     215
         2     215
         0.1     0
         2       0
         0.1     0
         0.6     0

Transform priority 4 texture 0, -40, 0 position.
