Syntax
text = Text(string, position, height, font, direction, up);
Inputs
Name | Type | Default | Description |
---|---|---|---|
string | string or field | none | text to be displayed |
position | vector | [0 0 0] | placement of displayed text |
height | scalar | 1 | height of the text (in world coordinates) |
font | string | "variable" | text font |
direction | vector | [1 0 0] | orientation of the baseline |
up | vector | perpendicular to baseline | orientation of vertical strokes of text font |
Outputs
Name | Type | Description |
---|---|---|
text | color field | renderable string object |
Functional Details
This module produces text that is displayed in space.
string | specifies the text to be displayed. If the parameter value is a string, that string is displayed. If the parameter value is a field, its "data" component must be TYPE_STRING. The data may be position or connection dependent:
|
position | specifies in world units the placement of the displayed text. It is used only when string is not a field. |
height | specifies the height of the text, in world units. |
font | specifies the font used for displayed text. You can specify any of the defined fonts supplied with Data Explorer. These include a variable-width font ("variable," the default) and a fixed-width font ("fixed"): area gothicit_t pitman roman_ext cyril_d greek_d roman_d script_d fixed greek_s roman_dser script_s gothiceng_t italic_d roman_s variable gothicger_t italic_t roman_tserFor more information, see Appendix E. "Data Explorer Fonts" in IBM Visualization Data Explorer User's Guide. |
direction | specifies the orientation of the baseline (see Note in next description). For example, a value of 10 for this parameter specifies that the text is aligned with the x-axis. |
up | specifies the orientation of the vertical strokes of the font used for the displayed text. Note: For string data in a field, the orientation of baseline and text can specified by using "tangents" and "binormals" components. In that way, each string can be oriented individually. These components should have the same dependency as "data" The "tangents" component corresponds to direction and "binormals" to up. The parameter specifications will override those of the field components. |
Components
Creates new "positions," "connections," and "colors" components.
