How do I draw text with GLUT / OpenGL in C++?

Question

How do I draw a text string onto the screen using GLUT / OpenGL drawing functions?

Answer 1

There are two ways to draw strings with GLUT

glutStrokeString will draw text in 3D

and glutBitmapString will draw text facing the user

Answer 2

void RenderString(float x, float y, void *font, const char* string, RGB const& rgb) {     char *c;    glColor3f(rgb.r, rgb.g, rgb.b);    glRasterPos2f(x, y);    glutBitmapString(font, string); } 

And you can call it like;

RenderString(0.0f, 0.0f, GLUT_BITMAP_TIMES_ROMAN_24, "Hello", RGB(1.0f, 0.0f, 0.0f));
