EdgeFill.itx
Type: Color, Reflect, Filter.
Overview:
=========
This Imagine 3.x texture can simulate a wireframe object or the Latticize
function by coloring the edges of an objects faces.
At least a 68020 and an FPU are required. The integer version of Imagine is
not supported, sorry.
Usage:
======
You can set the color, reflect and filter values separately. Using the color
value can give a wireframe look while the filter values can give a
simulation of the latticize function.
Parameters:
===========
Color Edge Size, Reflect Edge Size, and Filter Edge Size
--------------------------------------------------------
This is a fractional value between 0.0 and 1.0 that tells the texture how
much of the faces to fill. To get an effect similar to wireframe mode use
a small value. This doesn't give a perfect wireframe rendering however.
If you have very long and stretched triangles, the lines will vary in
thickness. Experiment to get the effect you want. A value of 0.2 is good
for imitating latticize.
Color Blend, Reflect Blend, and Filter Blend
--------------------------------------------
This sets the mix between the texture and the objects original color.
A 1.0 gives the texture its full effect, a lower number will blend
the texture with the original attributes.
Color Red, Color Green, Color Blue,
Reflect Red, Reflect Green, Reflect Blue,
Filter Red, Filter Green, and Filter Blue
----------------------------------------
This is where you give the values that will color the edges of the faces.
If you want to try out the latticize effect, set the objects filter value
to 255,255,255 and the filter values in the texture requester to 0,0,0.
This will not work right if the object is set specular since the empty
holes will still give a specular highlight.
