float start, float end, int cap)
{
float theta;
float angle_increment;
float x1;
float y1;
angle_increment = (float) (2 * MathHelper.pi()) / 90;
GL11.glPushMatrix();
GL11.glTranslatef(x + (width / 2), y + (height / 2), 0);
this.setProperties();
GL11.glBegin(cap);
for (theta = start; theta < end + angle_increment; theta += angle_increment)
{
x1 = (float) ((width / 2) * Math.cos(theta));
y1 = (float) ((height / 2) * Math.sin(theta));
GL11.glVertex2f(x1, y1);
}
GL11.glEnd();
GL11.glPopMatrix();
GL11.glColor3f(1.0f, 1.0f, 1.0f);
