Back to top Toggle Light / Dark / Auto color theme Toggle table of contents sidebar Mesh(ID) ¶ Mesh Data ¶ The mesh data is accessed in object mode and intended for compact storage, for more flexible mesh editing from Python see bmesh . Blender stores 4 main arrays to define mesh geometry. Mesh.vertices (3 points in space) Mesh.edges (reference 2 vertices) Mesh.loops (reference a single vertex and edge) Mesh.polygons : (reference a range of loops) Each polygon references a slice in the loop array, this way, polygons do not store vertices or corner data such as UVs directly, only a reference to loops that the polygon uses. Mesh.loops , Mesh.uv_layers Mesh.vertex_colors are all aligned so the same polygon loop indices can be used to find the UVs and vertex colors as with as the vertices. To compare mesh API options see: NGons and Tessellation Faces This example script prints the vertices and UVs for each polygon, assumes the active object is a mesh with UVs. import bpy me = bpy . context . object . data uv_layer = me . uv_layers . active . data for poly in me . polygons : print ( "Polygon index: {:d} , length: {:d} " . format ( poly . index , poly . loop_total )) # Range is used here to show how the polygons reference loops, # for convenience &#39;poly.loop_indices&#39; can be used instead. for loop_index in range ( poly . loop_start , poly . loop_start + poly . loop_total ): print ( " Vertex: {:d} " . format ( me . loops [ loop_index ] . vertex_index )) print ( " UV: {!r} " . format ( uv_layer [ loop_index ] . uv )) base classes — bpy_struct , ID class bpy.types.
