pyunity.meshes module

Module for meshes created at runtime.

class pyunity.meshes.Mesh(verts, triangles, normals, texcoords=None)

Bases: object

Class to create a mesh for rendering with a MeshRenderer

Parameters:

• verts (list) – List of Vector3’s containing each vertex
• triangles (list) – List of ints containing triangles joining up the vertices. Each int is the index of a vertex above.
• normals (list) – List of Vector3’s containing the normal of each vertex.

verts

List of Vector3’s containing each vertex

Type:list

triangles

List of lists containing triangles joining up the vertices. Each int is the index of a vertex above. The list is two-dimesional, meaning that each item in the list is a list of three ints.

Type:list

normals

List of Vector3’s containing the normal of each vertex.

Type:list

texcoords

List of lists containing the texture coordinate of each vertex. The list is two-dimesional, meaning that each item in the list is a list of two floats.

Type:list (optional)

Notes

When any of the mesh attributes are updated while a scene is running, you must use recompile() to update the mesh so that it is displayed correctly.

>>> mesh = Mesh.cube(2)
>>> mesh.vertices[1] = Vector3(2, 0, 0)
>>> mesh.recompile()

copy()

Create a copy of the current Mesh.

Returns:Copy of the mesh Return type:Mesh

static cube(size)

Creates a cube mesh.

Parameters:size (float) – Side length of cube Returns:A cube centered at Vector3(0, 0, 0) that has a side length of size Return type:Mesh

static double_quad(size)

Creates a two-sided quadrilateral mesh.

Parameters:size (float) – Side length of quad Returns:A double-sided quad centered at Vector3(0, 0) with side length of size. Return type:Mesh

static quad(size)

Creates a quadrilateral mesh.

Parameters:size (float) – Side length of quad Returns:A quad centered at Vector3(0, 0) with side length of size facing in the direction of the negative z axis. Return type:Mesh
