Real-Time Technology Path
For the 30fps real-time requirement, a hybrid rendering scheme is required:
- Model Lightweight: Use
--prune_ratio 0.6Parameter compression NeRF model with TensorRT acceleration (requires conversion to .plan format) - Optimization of the cone of vision: Add in the inference stage
--view_cone 60Limiting the range of viewpoints generated reduces the amount of 50% computation - asynchronous pipeline: 8 base angles (one for each 45°) pre-generated by Redis cache, dynamically interpolated intermediate frames
Hardware Selection Recommendations
- Single node solution: NVIDIA RTX 6000 Ada (48GB video memory) + CUDA 12.2
- Cluster solution: 4 A10G (24GB) viaMinkowskiEnginedistributed inference
- Mobile solution: output 256×256 resolution EGL texture, delivered via WebGL 2.0
