Vector3dFonts

Synopsis

This module produces labels that are geometries of full 3D stroke text with optional 3D shaded polygon extrusions based on the Hershey font system. They can be scaled, rotated, and translated. Other geometric operators work as well, such as colour, perspective, and material properties.

Parameters

Name	Type	Description	UI Control

label	string	label to be converted into geometry	Text
kerning	float	spacing between characters	Slider
stroke_width	float	width for strokes in Stroke mode or depth in 3D extrusion mode	Slider
font	int	font used for the label	Radio Box
linestyle	int	style of the label (Lines, Stroke Lines or 3D Extrusions)	Radio Box

Output Ports

Name	Type	Description

out	Mesh+Node_Data	contains the geometry
obj	DataObject	directly renderable object

Description

The module converts a special label to a geometry. It can be altered by the following parameters:

Label - defines the text, which should be converted and it can be altered through editing a UIText-field.

Kerning - defines the space between the characters
Stroke Width - defines the width of the strokes in Stroke mode and the depth in 3D extrusion mode respectively.

Both of these parameters can be altered through sliders.

Font - defines the font for the label (Selection between 13 different fonts is possible)
Line Style - defines the style for the label (Selection between "Lines","Stroke Lines" and "3D Extrusions" is possible)

These paramters can be altered through Radio-Buttons.

The module outputs a mesh "out" containing the geometry and a DataObject that can directly be rendered using the UViewer3D.

Parameters

Inputs

Label

text to be converted

Kerning

Value specifying the spacing between the characters in a range from 0.0 to 3.0

Stroke_Width

Value specifying the width of the strokes in Stroke-mode and the depth in 3D-Extrusions-mode respectively in a range from 0.1 to 1.0

Font

Value specifying the font used for the label. Choice between the following fonts is possible:

Roman Plain (= 0)
Roman Simplex (= 1)
Roman Duplex (= 2)
Roman Triplex (= 3)
Roman Complex (= 4)
Script Simplex (= 5)
Script Complex (= 6)
Italics Complex (= 7)
Italics Triplex (= 8)
Gothic English (= 9)
Greek Plain (= 10)
Greek Simple (= 11)
Greek Complex (= 12)

LineStyle

Value specifying the style used for the label. Choice between the following styles is possible:

Lines (= 0)
Stroke Lines (= 1)
3d Extrusions (= 2)

Outputs

out

Mesh and NodeData containing the geometry and colour information.

obj

Directly renderable object that can be used with the UViewer.

Example

The example contains the Vec3dFonts user module and an Uviewer3D. The user module provides a panel to change all parameters.
