Processing in Eclipse: problem with rotation
Jan 18th, 2010, 1:16am  
Ahoi and hi,

my first post: I study computer science and have a project for visualization of fuzzy-data. I choose eclipse as framework and embedded the core.jar from processing into my project. All works fine. But I have to rotate an object and I figured out, that the point of angle is the left upper corner. So I become problems with calculations, cause of performance. In the documentation I read that rotation is center of object?! But not in eclipse - my question: is there any possibility to say processing in eclipse to make it at the center of object?

Hope you understand what I mean. =)

Thanks for reading,

Hi and welcome,

Processing shouldn't be different in Eclipse.

To specify a different center where the rotation is applied, you may see it as a set of transformations:

0. Determine the center of your shape.
1. Move the shape center to the scene center (0,0,0). (-t1)
2. Apply the transformation (rotate)
3. Move back the shape to the original place. (+t1)
