Text, fonts

Hi, i’m quite new to OpenGL. I was wondering if it’s possible to display a message using an gl… or glut… function.
if it is possible could some one advice me how to do it!

Thanx a lot.
PS: I have this idea of drwaing a “heart” in 3D. could someone point me in the right direction of how to draw it?
Thanx again.

There are glut functions for drawing text.Take a look at the glut specification for more info(can be found in the developer documentation section here on opengl.org).Also in opengl.org to right you’ll find this link: http://www.opengl.org/developers/code/features/fontsurvey/index.html for further info on opengl font rendering.

If you want to use simple text, the is a glut function glutBitmapCharacter.

examples of the usage on my website:

What you can use is: (this is in java, you will need to change bits for ‘C’ i.e. remove the preceeding gl. on all the gl commands and maybe some other bits):

    //methods for displaying strings on the screen (in 2 different font sizes)
    public void RenderStringSmall(String renderStr, double x, double y){
    gl.glRasterPos2d(x, y);  
    glut.glutBitmapString(glut.GLUT_BITMAP_TIMES_ROMAN_10, renderStr);

    public void RenderStringLarge(String renderStr, double x, double y){
    gl.glRasterPos2d(x, y);  
    glut.glutBitmapString(glut.GLUT_BITMAP_TIMES_ROMAN_24, renderStr);

And then call it i.e.:

    RenderStringLarge ("Press n to start a new game", 175, 240);

(Robbed from my space invaders game I did some time last year)

Hope this helps
