调研方向

从 graphics/reconstruct_geometry.py 开始，沿着 Local Implicit 示例进入 core/reconstruction.py，重点查看第 106 行的 LIGOptimizer._init_graph，其中 tf.scatter_nd 会失败。复现示例中的潜在网格优化，并检查索引和 shape 输入的 dtypes。完成标准是重建过程能够继续执行并越过此 ScatterNd 错误。

由索引模型根据 Issue 内容生成。

描述

Trying to test Local Implicit sample I've found this issue:

Any tip on this?

Thank you in advance.
