Default Point of view - 12-09-2008, 09:18 PM

I am currently woring in Storytelling Alice and I am trying to create a variable of the type point of view. I cannot get it to be anything but position 0,0,0; orientation0,0,0)1 or position -4.26, 1.6, 7.38; orientation0, 0.97, 0) -0.26. I dont even know where the second position is coming from. I have tried draging and droping from properties and it wont work. What am I missing?

As far as I know, nothing. While a position vector can be set using the world level "right,up,forward" function, I know of no equivalent function to set orientation (nor do I fully understand where the option is coming from).

Additionally, the axis for Alice objects are not standardized, so a POV that works for one object may be totally wrong for another.

The best way to approach this is to use multiple dummy objects. Their only properties are their point of view and their vehicle, hence they require little memory. Yet they can be manipulated like any other object - and you can drop a new "dummy" at any object you have positioned on the screen. You can also set a POV variable to match the point of view of the "dummy" or the POV of any other object while the world is running if you want to do this interactively.

Dick Baldwin, both in the forum and in his tutorials has posted some nice examples.
