Interactive Scenario Creation in VR

This bachelor thesis aims to create a tool that enables inexperienced users to rearrange virtual scenes and author logic for dynamic objects contained in such scenes in virtual reality.

Tasks

• Solo development with feedback from supervisors
• Locomotion System “Scene in Hand” a.k.a. “Grab in Air”
• Selection and Manipulation Method: ray casting with uniform scaling for scene objects and UI elements
• Distance Independent Millimeter (dmm)
• Node-Based visual scripting
• Custom saving and loading system using JSON files for authored logic
• Dynamic node generation from given C# classes
• Implementation of feedback from regular meetings
• Interactive UI animations, moving UI elements in Z-Axis with DoTween
• UI/UX Design

Features

Scene in Hand Locomotion

The user can easily move, rotate and scale the scene to traverse the scene

Modify properties of GameObjects

The user can change the properties of any GameObject by selecting and altering the properties. If the node receives a signal the properties are applied.

Event list

The user can take any event node from the event list. The event node can be connected to GameObjects or other events to create AND/OR logic.

Event visualization

Setting up events such as a ProximityEvent is assisted with the needed debug information.

Animations

The user can easily set up animations by moving or scaling the blue template during recording. Those recordings are replayed once the GameObject receives a signal.

Project Timeline

Main focus was iterating the usability before polishing the application and writing the thesis
