Depends on what you need. By default you can switch the overall template 
path via TS (as well as the path for partials and layouts).

plugin.tx_yourext.view {
	templateRootPath = fileadmin/...
	partialRootPath = fileadmin/...
	layoutRootPath = fileadmin/...
}

But please be aware that you have to provide ALL templates and partials 
for that extension in those folders then.


If you only like to switch a template for a certain controller or 
provide a layout selector or something in your flexforms you will have 
to override the "setViewConfiguration" method in your controller. Or, 
pass the layout setting to the view and use it to render a certain 
section or partial there.

I suppose you need to calculate that in the view. There is a viewHelper 
to access/render a TS object path.

<f:cObject typoscriptObjectPath="lib.your.TSobject" 
currentValueKey="nameOfAProperty">{someObject}</f:cObject>

As you can see in the example, you can pass objects to the viewHelper 
and it will convert it's properties automatically to an array that's 
accessible from within the TS then. If that doesn't work for you, you 
always can create your own viewHelper doing some maths.

Sorry, can't help you with that.
