HexSwirl help :(

OpenGL OpenGL: Basic Coding

Hi!
ive been working on this project for sometime now, and i just cant get my hexswirl function to work :frowning: please help. its supposed to look like this: http://www.slidefinder.net/C/Computer_Graphics_using_OpenGL_3rd/15456597/p2 (the picture in slide 22 or 24)
I need this for a project which is due next week :frowning:

by the way this is what ive come up with so far:

void Polygon11::draw(float n, float s, float a)
{
float r1;
double inc = 5.0/100;
double angleInc = 23.14159265/6.0;
double aaa;
r1 = radius;
for (int j = 0; j < 50; j++)
{
aaa = j 3.14159265/180.0;
glBegin(GL_LINE_LOOP);
for (int i = 0; i < 6 ; i++)
{
a += angleInc;
glVertex2f(r1scos((iaaa)+10),r1ssin((iaaa)+10)); glEnd();
r1 += inc;
}

}

Try this


I initially posted the code but have now removed it since this is your assignment and u should know how to do it.

Basically, the inner loop creates a hexagon. The outer loop reduces the radius and rotates the hexagon slightly (3 degrees). Which gives this output

mobeen you’re so kind :slight_smile:

Hmmm atleast he tried his best to get it work.

After posting i realised I shouldn’t have posted the code since this was an assignment given to him. May be i will edit my reply to remove the code.
