3D Environment Design for Unity VR Emergency Simulation

Project Title: Destroyed Coastal Village 3D Environment Design for VR Emergency Simulation in Unity

Purpose: Development of a VR Environment for our Prototype for humanitarian emergency response simulation, aiding purpose-led organisations in scaling and strengthening their global social impact.

Vision: This proof of concept aims to demonstrate to partners in the humanitarian section the advanced capabilities that VR can offer. By showcasing high-quality visuals rendered in XR through effective optimization strategies, Nuwa seeks to emphasize the critical role of immersive technologies in disaster preparedness and response.

Target Sectors:

• Humanitarian and Emergency & Disaster Response Sectors

Service Requirements:

Scope of Work:

• Design and development of a 50m x 50m photorealistic coastal village environment resembling a post-hurricane/post-tsunami scene flooded with water like Haiti in the year 20xx with 3 roads, the main one leading to a short beach of pebbles and the sea (see images below).

• Environment must be fully optimised and ready for deployment on Meta Quest 3 VR.

Technical Performance Requirements:

• Batch/frame: Maximum 180 calls (preferred maximum 100 calls)

• SetPass: Maximum 110 calls (preferred maximum 75 calls)

• Shadow Casters: Maximum 55

• Triangles: Maximum 200k (preferred maximum 100k)

• Vertices: Maximum 200k (preferred maximum 100k)

• Textures: Maximum resolution 2048x2048px (preferred resolution 512x512px)

• Shadows: Maximum resolution 1024x1024px (preferred resolution 128x128px)

• CPU Render Time: Maximum 12ms (preferred <4ms)

Optimisation Requirements:
To achieve the above technical performance, the following optimisation techniques could be expected but not limited to:

1. Single Texture Atlas: Minimize texture calls through effective texture atlas design.

2. Shadow Mapping: Efficient use of shadows to reduce computational load.

3. Level of Detail (LOD): Three LOD levels for environment assets.

4. Impostor Conversions: Implement impostor assets for distant objects.

5. Baked Lights: Static asset lighting must be baked.

6. Lighting Probes: Utilization for dynamic asset lighting.

7. Spatial Partitioning: Segmentation of the environment for performance efficiency.

8. Occlusion Culling: Effective visibility management to reduce rendering overhead.

Deliverables:

1. 3D Environment Design:

   • Realistic coastal village environment in Unity.

   • Photorealistic assets depicting hurricane aftermath, including damaged buildings, debris, vegetation, and water bodies (see reference pictures below)

2. Optimised VR Scene:

   • Unity project setup compatible with Meta Quest 3 VR.

   • Fully optimised environment meeting or exceeding performance requirements.

3. Documentation:

   • Technical optimisation report detailing methods used.

   • User and maintenance guide for environment updates.

4. Testing:

   • Comprehensive performance testing results.

   • Bug fixes and iteration as per feedback.

Timeline:

Evaluation Criteria:

1. Technical Expertise: Proven experience in developing high-performance 3D environments for VR.

2. Optimization Capabilities: Demonstrated ability to meet stringent performance requirements.

3. Portfolio Quality: High-quality examples of similar VR environment projects.

4. Project Management: Ability to meet timelines and deliver comprehensive documentation.
