Dynamic mask


Any idea how to make a dynamic mask to make somes projections on several objects?

I can make it with a rectangle (quad, rectangle), a trapeze but with some dynamic polygon?

It is possible to create the desirable geometrical shape by creating a texture but for me the idea is to be able to modify her.

maybe VertexBuffer (EX9.Geometry Join) and Mesh (EX9.Geometry Join) can help you.

Also a Grid with an ArbitraryPoint transformation could be your cup of tea (can be easier than making a mesh from scratch).

The ApplyTransform help patch can be a little confusing at first but it’s a pretty simple node. For your purposes you can ignore the XYZ output and just give it 3D inputs
