There are often times when you might need to use text in your Verge3D application - here are a couple of ways that you can do so.

1. DOM + CSS

Using HTML is generally the easiest and fastest manner to add text. This is the method used for descriptive overlays in most Verge3D examples.

You can add content to a

  • Select a font Click Options-Font settings. Select a font from among those installed on your system. This is also where you will set the size (in pixels) of the font, and can make it bold or italic.
  • Bitmap Font Generator. This program will allow you to generate bitmap fonts from TrueType fonts. The application generates both image files and character descriptions that can be read by a game for easy rendering of fonts.

So I am using three.js for a project and would like to be able to use a font other than the default 'helvetiker'. I've done some digging and discovered that you need to convert the font using typeface.js to get a font file, and have already done that, I just can't figure out how to 'plug' this font into threejs. . I have Python 2.6.5 on my box I import from the Python Standard Library: from future import withstatement #backward compatibility import sys, os, re, codecs, math, json, random from optparse import OptionParser #in./bmfb.py. fontforge (The Python bindings of fontforge) On Debian and Ubuntu the package is called python-fontforge $ sudo.

Description

and use CSS markup to position absolutely at a position above all others with a z-index especially if you are running Verge3D full screen.

#info { position: absolute; top: 10px; width: 100%; text-align: center; z-index: 100; display:block;}

2. Draw text to canvas and use as a Texture

Use this method if you wish to draw text easily on a plane in your Verge3D scene.

3. Create a model in your favourite 3D application and export to Verge3D

Use this method if you prefer working with your 3d applications and importing the models to Verge3D

4. Procedural Text Geometry

If you prefer to work purely in v3d.js or to create procedural and dynamic 3D text geometries, you can create a mesh whose geometry is an instance of v3d.TextGeometry:

new v3d.TextGeometry(text, parameters);

In order for this to work, however, your TextGeometry will need an instance of v3d.Font to be set on its 'font' parameter. See the TextGeometry page for more info on how this can be done, descriptions of each accepted parameter, and a list of the JSON fonts that come with the v3d.js distribution itself.

Examples

WebGL / geometry / text
WebGL / shadowmap

If Typeface is down, or you want to use a font that is not there, there's a tutorial with a python script for blender that allows you to export text to Verge3D's JSON format: http://www.jaanga.com/2012/03/blender-to-threejs-create-3d-text-with.html

5. Bitmap Fonts

Pixel Font Maker

BMFonts (bitmap fonts) allow batching glyphs into a single BufferGeometry. BMFont rendering supports word-wrapping, letter spacing, kerning, signed distance fields with standard derivatives, multi-channel signed distance fields, multi-texture fonts, and more. See three-bmfont-text.

Stock fonts are available in projects like A-Frame Fonts, or you can create your own from any .TTF font, optimizing to include only characters required for a project.

Some helpful tools:

  • msdf-bmfont-web(web-based)
  • msdf-bmfont-xml(commandline)
  • hiero(desktop app)

Loads an AngelCode BMFont file in browser (with XHR) and node (with fs and phin), returning a JSON representation.

Currently supported BMFont formats:

Font
  • ASCII (text)
  • JSON
  • XML
  • binary

See Also

See text-modules for related modules.

Usage

load(opt, cb)

Loads a BMFont file with the opt settings and fires the callback with (err, font) params once finished. If opt is a string, it is used as the URI. Otherwise the options can be:

  • uri or url the path (in Node) or URI
  • binary boolean, whether the data should be read as binary, default false
  • (in node) options for fs.readFile or phin
  • (in browser) options for xhr

Bmfont

To support binary files in the browser and Node, you should use binary: true. Flux 7 1 3 – advanced web design tool. Otherwise the XHR request might come in the form of a UTF8 string, which will not work with binary files. This also sets up the XHR object to override mime type in older browsers.
