The text pattern types influence the reflectance of a material according to the outline of some text, as displayed in a selected font. There is a colored and an achromatic version.
Colortext is a procedurally defined color pattern, that writes text on the affected surfaces.

Start Point:
The reference point of the text. This is the top left
corner of the field where the text should appear, in
world coordinates.
Right Vector:
Down Vector:
The orientation of the text. The text lines are layed
out so that they follow the right vector, and the
text column follows the down vector. The absolute and
relative sizes of those two vectors determines
character size, orientation, aspect ratio, and slant.
Foreground:
Background:
The color values to modify the text and the background
with.
Alignment:
The formatting of multi line text.
| None (Monospaced) | A uniform character spacing algorithm is used that garantees every character will appear in a precisely determined position. | |
| Left | A proportional character spacing algorithm is used, that preserves right margins and indentation. | |
| Block | A proportional character spacing algorithm is used, but the word placement is adjusted to fill the available horizontal space. |
Spacing
This selection is only available when one of the
Left or Block Alignment options
is selected. It modifies the character spacing in
the range of Very Narrow, Narrow,
Normal,Wide, and Very Wide.
Font File:
Selects the font for the text. Radiance includes
the fonts "helvet" (a common non-serif font) and
hexbit4x1 (a monospaced font).
Text File:
The file to read the text from. If "-- no file --" is
selected, then one line of text must be given in
the next field.
Import...
This button starts a file open dialog to select an
external text file. This file is then copied
into the project and will be available for selection.
Text Line:
This entry field is only active if "-- no file --" is
selected as a text file. The text entered here will be
used instead of text taken from a file.
Brighttext is a procedurally defined reflectance pattern, that writes text on the affected surfaces.

Foreground:
Background:
The values to modify the text and the background with.
All three color values of the modified material will be
multiplied with those values.
Alignment:
The formatting of multi line text.
