Tutorial 19 : 3D Font

•  Introduction

This tutorial is a Gl4java specific tutorial. We will use here GLF to render 3D text.
Neither Jogl nor Jogl-JSR231 support GLF utilities.

If you want to use 3D Font with Jogl/Jogl-JSR231, take a look at the Jogl Add-On page.

•  3D text using GLF

•  Initialization

GLF provide access to draw 3D text using predefined font.
    GLF glf = new GLF()

Predefined fonts are located in the glf support jar (gl4java-glffonts.jar) in the *.glf format.
To use one of these fonts, we need to load it with :
    glf.glfLoadFont(glfFont)
glfFont is the glf file name (file with glf extension).
Here is a list of font available : aksent1.glf, alpine1.glf, arial1.glf, broadway1.glf, chicago1.glf, compact1.glf, courier1.glf, cricket1.glf, crystal1.glf, garamond1.glf, gothic1.glf, penta1.glf, present_script1.glf, techno0.glf, techno1.glf & times_new1.glf.

If you want to use an another font, don't forgot to unload the previous one :
    glf.glfUnloadFont()
 

•  Drawing

There is two interesting features : text centering & text direction :
    glf.glfStringCentering(centered)
    glf.glfStringDirection(direction)
centered tell if the string is centered of not.
direction is the rendering direction of the text. This can be one of those constants : GLF_RIGHT, GLF_DOWN, GLF_UP, GLF_DOWN

Now, glf is initialized. we can draw a 3D text :
    glf.glfDraw3DSolidString(text)
text is a string to draw a the current position

Here is an example of drawing a 3D text using GLF :

•  Keys

F : switch to a different GLUT font
