context inside js or main patcher?

Beshmeee — Wed, 24 Aug 2011 13:10:50 +0000

Hi, I’m trying to render to the same context form objects in a normal Max Patch and also from within a script in a js object as well.

I’m not sure how to do this or which is the best place to do it.

I need to extract intersection coordinate hence my choice to use js, and I also need to be able to create and destroy gl objects on the fly.

I also need to be able to grab individual object and move then by the mouse.

I’ve been using the following js examples:
jitterlistentest
jitterhittest
and have created my script from these, but I also need to be able to work in the way that jitter-gui-sliderexample works in terms of both creating the context outside of the js and also the way it handles how the mouse grabs only one object at a time.
I’m struggling with tje javascript as I am a complete novice in coding and Java.

Hope someone can offer some advice?

cheers, B.

Having said that is is possible/easier to do the intersection testing and object selecting without using the js objects – perhaps using sketch?

Hello,
As I know you can easily use JS, OpenGL and creating the context outside of the js. See attachments

Thanks Kyred.

I’m a complete novice to any kind of programming (no C, C++, Java, anything), so this is all trial and error, and picking it up as I go along – rather slowly I might add!

This helps a lot.

Cheers, B.

That’s great, some things still to learn but this helped a lot Kyred.

Is it possible to access gl objects created in normal jitter objects in a patcher (eg gridshape) from within the js?

I ideally want to make as much outside of the js as possible leaving only the interesction and object selection/movements inside the js (as I’m having problems doing these things in other ways). I’ve been using the intersect, jitterhittest, GUIElements, GUISliderElement, etc files as guides, but not successfully managed to combine the bits I need as they are still rather too advanced for me. Still the projects I’m working on requires me to be able to create and destroy the gl objects selects and move them with the mouse.

If anyone has some pointers (Kyred?) on where to look that would be great.

Cheers, B.
