• Supports digital twins for renovation, retrofitting, and maintenance planning.
• Enhances collaboration between clients and design teams with realistic 3D previews.
• Reduces reliance on expensive physical models or multiple prototypes.
• Facilitates accurate lighting and material simulation for interior and exterior design.

Importance of NeRF in Gaming

• Generates immersive 3D environments from real-world photographs.
• Reduces asset creation time for large-scale open-world games.
• Supports photorealistic textures and lighting without manual modeling.
• Enables dynamic scene adaptation and virtual cinematography.
• Enhances realism in virtual reality (VR) and augmented reality (AR) experiences.
