METHODS AND SYSTEMS FOR PROVIDING CUSTOMIZED VIRTUAL AND AUGMENTED REALITIES

Methods are disclosed for providing alternate reality (e.g., virtual reality) representations to users. Exemplary methods employ data collections (e.g., stacks) which affect the virtual representations of baseline virtual models. Data collections contain layers which contain deltas. The deltas specify modifications to the baseline virtual reality world or model. The deltas may be geocoded, while the layers that contain them may not be geocoded. Separately selectable layers are used to temporarily modify or substitute baseline data or virtual elements (e.g., virtual objects) that are ultimately presented to a user on an output device. Conflict resolution algorithms harmonize conflicts between layers of a collection.
