About Occ generation metric

[fengjiang5]

Hi, thanks for your great work onX-Scene! I am currently working on 3D occupancy generation and finding your framework very inspiring.

I am trying to reproduce the generation results but have some questions regarding the training and evaluation details.

• Metric Implementation: I am interested in how the geometric quality is evaluated. Could you release the code or provide details on the implementation, about metric in 2D and 3D;
• mIoU of occ generation in Table 7 shows 92.4 when generation, could you please release the pth for me to make fair comparison.

Thank you for your time and contribution!

Hi, thanks for your interest in our work!

Regarding the questions you raised:

1. Evaluation code for generation metrics: We have just updated the relevant evaluation scripts. Please refer to: eval_occgen.
2. Regarding Table 7 and weights:
   • Please note that the 92.4 mIoU reported in Table 7 is the metric for occupancy VAE reconstruction, rather than the generation task.
   • As for the weights, we refactored the codebase for the open-source release, so the weights are currently being prepared. Please stay tuned and thank you for your patience.
