Wrap over Object

To start, we need two objects: the first being the object to be wrapped, and the second, the object to which we will wrap the first. From here we need to work out where on our second object we want the first object to appear. We need good UV's and a point split, using the UV's, and promoting to a point attribute. We then need a wrangle with "@P = @uv". This will give us our second mesh in uv space. We don't actually use this step but it's a great way of visualizing what we're doing.

From here we can use a transform to move our first object to the new UV layout and orientate it. It's important we have the first mesh here because now our first objects 3D coordinates are in the same space as the second object's UV coordinates.

Now we need to make use of the uvsample function. We need a wrangle with the first input being the first object and the second, the second object(but before we split the points). Now we need to add just three lines of VEX.

This is working under the hood, but we're forgetting about the z axis. We can only use the x and y with "uvsample". So we need to track the local transform before so we can reimplement it after. We need to emend our code with this.

Now we have two extra variables in our wrangle, "scale", simply scales the height of our wrapped object. "Global_Height", is useful for moving the wrapped object up and down relative to the second object. What we're doing in the VEX is taking the @P.y, which is the relative height, and multiplying the normal by the relative height.

We now have our first object, wrapped over our second object. We can also move the first over the mesh by using the transform before the "uvsample" wrangle. We also have some controls for how our mesh gets wrapped around the object.
