Matrices/Math related question


Recommended Posts

Hi, I think this may be a little bit more related to math but I can't seem to find the solution.


            stack.translate(1F, 2F, 3F);
            stack.scale(2.0F, 3.0F, 4.0F);


            stack.translate(1F, 2F, 3F);
            stack.scale(2.0F, 3.0F, 4.0F);

Is it possible, given x1 and calculate the value of x2?

No, for two reasons:

1) x1 and x2 are not equal and have no apparent relationship

2) matrix transformations are non-associative

The only thing I can think of is working backwards from the output of the first chunk, removing the rotation, removing the scale, then adding the new rotation and scale back.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.
