How it works:

Click Texture Editor and Texture Image Dialog for full
view.
Feature Highlights:
-
Drag and drop GIF, JPEG, PNG, and RGB (SGI-image)
files onto the texture palette.
-
Get information on each texture image by double-clicking it, or choose Edit
> Show Image. This opens the Texture Image Dialog, which
displays the image size, image name and location, and the components to
the image. RGB files can consist of one to four components:
-
1 = Black and White (BW)
-
2 = BW plus Alpha Transparency
-
3 = Red, Blue, Green (RGB)
-
4 = RGB plus Alpha Transparency
-
By default, the texture is mapped to the largest face of object. The
texture is wrapped to cover smaller faces by stretching the image.
Cube, Cylinder, Sphere, and Cone have default mappings.
-
To adjust the image, select repeat or clamp from
the Options pull-down button and experiment with the sliders and
thumbwheels.
-
For fine-tuning, use the PEP Texture
Applicator.
The Menu Bar:
-
File:
-
New lets you create a custom palette.
-
Import Image lets you import a file into an empty
texture square.
-
Warning On Size warns you if the image you are importing
is larger than 128x128 pixels. Large images will affect your scene's
rendering performance, so try to keep texture images to a minimum size.
-
Reset System Palette lets you return to the default
palette. Use this if you've modified a texture and want to revert to
the original.
-
Delete Custom Palette lets you delete any custom
palettes that you've created. You cannot delete the default palettes.
-
Close closes the Texture Editor.
-
Edit:
-
Show Image shows a larger image with details on image
size and type.
-
Delete Image removes a selected texture.
-
Palettes:
-
The Palettes menu lists all the texture palettes installed on your
system.
-
Go directly to a texture palette by selecting its name.
-
Use Next and Previous to page through the
palettes.
The Options Menu & Thumbwheels:
-
Use to specify scaling and repetition of a
texture on an object:
-
Choose a Repeat menu item; thumbwheels read Repeat S
and Repeat T
-
Choose Clamp; thumbwheels read Scale S and Scale
T
-
Repeat specifies the number of times you want the texture to
appear on a model. Use the Repeat S and Repeat T
thumbwheels or type-in fields to specify.
-
Clamp makes the texture larger or smaller on the model
without repeating it. The edge of the texture is smeared across the
object instead. Use the thumbwheels labeled Scale S and Scale
T to make the texture larger or smaller.
-
Repeat S repeats the texture in one dimension of the object.
Use the thumbwheel labeled Repeat S to display more or fewer
repetitions.
-
Repeat T repeats the texture in another dimension of the
object. Use the thumbwheel labeled Repeat T to display more
or fewer repetitions.
