Detailed Description

Class representing a sub-mesh containing local vertices and triangles.

Vertices and normals have the same size and are linked by id stored in triangles.

Note: uv contains data only if your mesh have textures (by loading it or after calling sl.Mesh.apply_texture()).

Functions

◆ vertices()

np.array[float] vertices ( self )

NumPy array of vertices.

Vertices are defined by a 3D point [x, y, z].

◆ triangles()

np.array[int] triangles ( self )

NumPy array of triangles/faces.

Triangle defined as a set of three vertices indexes [v1, v2, v3].

◆ normals()

np.array[float] normals ( self )

NumPy array of normals.

Normals are defined by three components [nx, ny, nz].

Note: A normal is defined for each vertex.

◆ colors()

np.array[int] colors ( self )

NumPy array of colors.

Colors are defined by three components [r, g, b].

Note: A color is defined for each vertex.

◆ uv()

np.array[float] uv ( self )

UVs defines the 2D projection of each vertices onto the texture.

Values are normalized [0, 1] and start from the bottom left corner of the texture (as requested by OpenGL).
In order to display a textured mesh you need to bind the texture and then draw each triangle by picking its uv values.

Note: Contains data only if your mesh has textures (by loading it or calling sl.Mesh.apply_texture()).
