材质引用（usemtl）：关联.mtl材质，如mtllib 章贡客家竹雕《竹郁八境台》.mtl。

Geometric data is stored in ASCII encoding, with the following key fields:

Vertex coordinates (v): Format: `v X Y Z` (unit: mm). This field records the three-dimensional structure of the *Zhanggong Hakka Bamboo Carving: Bamboo-Framed Eight Scenic Platforms*, which preserves the natural texture of the bamboo board, with carved lines naturally integrated with the bamboo grain. For instance: `v -0.983193 0.139696 0.066720`. The full work combines traditional bamboo carving craftsmanship with the Song Dynasty ancient city landscape, showcasing the ancient city's unique charm and iconic Song Dynasty architecture while presenting an elegant and refined texture.

Texture coordinates (vt): Format: `vt U V`. This field is used to associate bamboo grain textures, with an example: `vt 0.435873 0.001221`, ensuring no misalignment during bamboo texture mapping.

Face definitions (f): Format: `f 16/33/70 33/16/69 35/18/73 18/35/74`. Approximately 2.3 million faces are included to guarantee high modeling accuracy.

Material reference (usemtl): Associated with .mtl material files, with an example command: `mtllib Zhanggong Hakka Bamboo Carving Bamboo-Framed Eight Scenic Platforms.mtl`.
