if this gets posted twice I'm sorry, think I did something wrong the first time

is there anyway to keep track of a rotation, you trigger by using jit.gl.handle on a world?

I want to have a videoplane running fullscreen that counterRotates in function of the world, so that it always remains more or less fullscreen and straight.

I need to be able to have some images/texts in fullscreen readable at all times.

but they also need to be able to drift in function of the world, being almost in sync (contra sync actualy) to the world

I tried to derive info from the dumpout but havn't had any luck with that

If I get it out of the world, would it be tricky math to get it running?

jit.gl.handle outputs a normal message rotate ..... so the rotating 

information is there before it rotates your world.

have a look at the jasch objects, they are very useful for

information is there before it rotates your world.

transformation stuff

The only way I have found to do this (although I am quite open to anyone's information to the contrary) is to use the left output from jit.gl.handle. This will give you commands such as:

Just use [unpack] to separate the numbers, and off you go into the wide world of mathematics. In your case, just multiply the first of the four numbers by -1, and leave the others alone.

No need to keep track of rotation. Check out the new @transform_reset

attribute. Most gl objects support it. It wil keep anything from

transforming witht the rest of the context. Really easy for screen overlay

kind of things.

If I understood corectly, there's no need to keep track of rotation, it is 

as simple as adding @trasnform_reset 2 attribute to videoplane:
