[UPDATE: Don't use this, use the Max built-in "jit.gl.meshwarp" object. Enjoy!]

[UPDATE: improved a lot the behavior of the mask! Now it doesn't use a mesh but an algorithm to check if points are inside a polygon. Enjoy!]

Hi dear Patrons!

I'm happy to introduce you to this abstraction I've been working on for a while.
It's a projection mapping tool that let's you do projection mapping directly from within Max!

During my last project I found myself struggling to map 4 videos to a curved surface, and I thought it would be lovely if I could just do this using my mouse.
So I developed this little thing.

It is just a beta, but the basic functionality is there.
It will evolve but I need a lot of your feedback to know what is missing and what could be done better. 

Hope you will enjoy it!

Instructions:

How to install:
unzip the file inside the packages folder of your Max installation. 
Usually "Documents->Max8->packages.
Then you will be able to use the abstraction in all your patches by creating the object
"jit.world_maxmapper"

How to use:

See the help file for the messages you can send to the abstraction.

Use the jit.world_maxmapper instead of a jit.world object, you can still use attributes and messages like if it would be a normal jit.world. 
Use "Shift + drag" to select multiple vertices, use "Ctrl / Cmd + drag" to move them afterwards.

You can select all the vertices of the grid and the mask by pressing "Ctrl / Cmd + A", and then move them by dragging with the mouse while keeping the keys pressed. 

See the attached video for details.
