STL アナライザー

File format

Extension of the uploaded file (e.g. GLB, STL, OBJ).

File size

Total size of the uploaded model file on disk.

Data footprint

Estimated GPU usage for geometry buffers plus textures (including mipmaps).

Vertices

Number of vertices in the mesh geometry.

Triangles

Number of triangular faces in the mesh.

Size

Bounding box dimensions in millimeters along X, Y and Z.

Volume

Solid volume of the closed mesh, from tetrahedral decomposition.

Surface area

Sum of all triangle areas (square centimeters).

Watertight

Whether every edge is shared by exactly two triangles. Open meshes may have holes or non-manifold edges.

Boundary edges

Edges that belong to only one triangle, indicating holes.

Non-manifold edges

Edges shared by more than two triangles, indicating non-manifold topology.

Connected components

Number of independently connected mesh parts.

Isolated vertices

Vertices not referenced by any face.

Normals

Whether vertex normals are fully present (affects lighting).

Avg. edge length

Mean length of all triangle edges in millimeters.

Triangle quality

Mean triangle shape quality; equilateral = 100%, skinny triangles score lower.

Materials

Number of materials assigned to the model.

Textures

Number of texture images embedded or referenced.

Resolutions

Pixel size and format of each texture slot.

GPU memory

Estimated VRAM used by textures including mipmaps.
