centres of rotation

I'm just playing around with the centres of rotation - working on having them move around - this one was simple to make, more complex is proving more difficult.

Indecisive Netting moves the rotation mesh around, while Devil Is In The Details adjusts the resolution of the rotation mesh (as well as the corner that the mesh "zooms" from)

I finally invented a term for what we're doing here - "rotation mesh" sounds so much nicer than "multiple centres of rotation"

Nice Krash but how do we get the rotation of teh mesh moving around within the same 'block' Indecisive Netting just moves the offset of the amount of points of rotation and the center of rotaion still remains in the top left corner.

I want the centre of rotaion in the middle of the screen (and then move from there). I have played with a bit of stuff but cannot get what I want.

I know this must be possible but don't know how?

Anyone?

No worries got it.

code:


per_pixel_1=q7 =4;

per_pixel_2=q8 =4;

per_pixel_3=cx = (0&((x)*q7-q1))*(1/q7)+0.1*q1;

per_pixel_4=cy = (0&((y)*q8-q2))*(1/q8)+0.1*q2;

Where q1 & q2 is the offset within the 'block'

Ahh - I see what you're doing - the different areas of rotation are constant, but each area rotates around and arbitrary point within itself. Clever.

What is it with you guys and forgetting zips.
