Virtual Spatial Design Unity Project

Details

Student Name : Bashar Beshoti

About The Project

Virtual Spatial Design, is a BSc final project at University Of Haifa supervised by Prof Roi Poranne. It leverages geometric comprehension and full algebraic functionality to render scenes in real-time. The primary aim of the project is to facilitate interior designing through various functionalities such as PushPull+, Mesh Model Transformation, Scalping Mesh Model, among others.

• Doucmentation :

  1. Unity Documentation

Week 2 - Setting OpenXR & MixedReality Package

• Via MixedRealityFeatureTool, I downloaded MRTK3 package , then sets up the VR setup enabling player movement.
• Installation of ProBuilder plugin.
• XR Device Simulation enabling player controls in action on PC.

Figure 1 : XR Device Simulation - This utility lets you simulate user inputs from plain key presses (be it from a keyboard and mouse combo or a controller) to drive the XR headset and controller devices in the scene.

Week 3 - Creating A Basic Enviroment & Character Movement & Setting L/R Controllers

Building an enviroment along with setting up L/R controllers as it should be. Afterwards, worked on Character ActionMap for Character Movement.

Week 4 - ProBuilder Script API

Creating classes Polygon, Rectangle,Quad and Point as 2D Mesh Objects. For the 3D Mesh Objects, I've used ProBuilder CreateShape Supporting multiple different game objects useful for archicture in real-time.

Week 5 - Real-time Line Drawing + GUI Modification

Instead of blindly chosing vertices, i worked on drawing a line that visualize the edges of the polygon during drawing procedure. Furthermore, i added Canvas that hold ons the main GUI for user that accompany the user during runtime.

Week 6 - Real-time Selection & Hover Highlighting

Adding MeshCollider for each created Mesh during runtime and enabling both Hover-Highlight and Selection.

Figure 7 : Real-time Selection & Hover Highlighting over runtime created objects only

Week 7 - Basic Transformation & Singleton Class

Creating the basic Transformation for Mesh Objects (Scale,Rotate and Translate) where the user can modify objects Transform componenet. Moreover, establishing a singleton class that contain all the nessecary data to move data from scene to another and hold on the nessecary game objects.

Week 8 - Scenes Managment + Scene UI

Creating Multiple Scenes; Welcome, Settings, Main and Editor. where Welcome is an intro page for the project, the Settings responsible for Charachter & Game Settings, lastly Main and Editor are the project pillars that I am relying on.

Week 9 - PushPull+ (Extrusion/Inclusion)

Creating Extrusion and Inclusion in runtime over game object that has been sent to Editor scene where it provides mesh object shape manipulation + Optimization process where i deleted the non-nessecary elements (Vertices and Faces).

Week 10 - Options List + Game Message

Creating a Options list which contain :

1. Subdivision Game Object:
2. Flipping Edges
3. Flipping Faces
4. Triangulate / To Quad
5. Undo
6. Redo
7. Visualize Skeleton/Grid
8. Viusualize Vertices

Week 11 - Face Subtraction & Hole Generation

Subtraction of a Sub-face from the main face where it divide the face into 9 different faces. Hole generation contain same principle except it deletes the subface as well generating a hole inside a face.

Week 12 - Fixing Buggs

I've modified the structure of the scenes and added few things and fixed few bugs along the execution.
