Hello,
I have question how can I draw pipe in opengl? I am using C++ and glut, I found something like this but i dont understand the code:
Code :
int ACC=48; float a,p,q; int i; glBegin(GL_QUAD_STRIP); for (i=0;i<=ACC;i++) { a = i*PI*2/ACC; p = cos(a); q = sin(a); glNormal3f(p, q, 0.4); glVertex3f(0.7*p, 0.7*q, 0.8); glNormal3f(0.0, 0.0, 1.0); glVertex3f(0.7*p, 0.7*q, 10); } glEnd();
Generaly I want to draw a spring but not with gl_Line_Stripe becouse i must to put material on it:(
