Support / Rotating multiple objects around a single object or center
« on: March 14, 2018, 04:47:23 am »
I'm struggling with a rotation concept.
I'm trying to rotate objects sequentially around a single point. Similar to each of the hours on a clock.
For example, I have 10 primitives and I want to loop these around a central point.
In opengl I could do something like:
But I can't seem to achieve this through jpctae. From what I understand, all of the rotations/translations are performed at the end. So it isn't possible this way.
I've also tried attaching to a dummy object then rotating that but it's the same result because of the same fact.
Would using matrices solve this? Combinig the translation and rotations?

Code: [Select]
for (int i = 0; i < 10; i++)
{
gl.glPushMatrix();
gl.glRotatef(((float) i / 10) * 361f, 0f, 0f, 1f);
gl.glTranslatef(0, 5f, 0);
clockBar.draw(gl, 0);
gl.glPopMatrix();
}
