Mesh¶

class pyrender.Mesh(primitives, name=None, weights=None, is_visible=True)[source]¶

A set of primitives to be rendered.

Parameters:	name (str) – The user-defined name of this object. primitives (list of `Primitive`) – The primitives associated with this mesh. weights ((k,) float) – Array of weights to be applied to the Morph Targets. is_visible (bool) – If False, the mesh will not be rendered.

Attributes Summary

`bounds`	The axis-aligned bounds of the mesh.
`centroid`	The centroid of the mesh’s axis-aligned bounding box (AABB).
`extents`	The lengths of the axes of the mesh’s AABB.
`is_transparent`	If True, the mesh is partially-transparent.
`is_visible`	Whether the mesh is visible.
`name`	The user-defined name of this object.
`primitives`	The primitives associated with this mesh.
`scale`	The length of the diagonal of the mesh’s AABB.
`weights`	Weights to be applied to morph targets.

Methods Summary

`from_points`(points[, colors, normals, …])	Create a Mesh from a set of points.
`from_trimesh`(mesh[, material, is_visible, …])	Create a Mesh from a `Trimesh`.

Methods Documentation

static from_points(points, colors=None, normals=None, is_visible=True, poses=None)[source]¶

Create a Mesh from a set of points.

Parameters:	points ((n,3) float) – The point positions. colors ((n,3) or (n,4) float, optional) – RGB or RGBA colors for each point. normals ((n,3) float, optionals) – The normal vectors for each point. is_visible (bool) – If False, the points will not be rendered. poses ((x,4,4)) – Array of 4x4 transformation matrices for instancing this object.
Returns:	mesh – The created mesh.
Return type:	`Mesh`

static from_trimesh(mesh, material=None, is_visible=True, poses=None, wireframe=False, smooth=True)[source]¶

Create a Mesh from a Trimesh.

Parameters:	mesh (`Trimesh` or list of them) – A triangular mesh or a list of meshes. material (`Material`) – The material of the object. Overrides any mesh material. If not specified and the mesh has no material, a default material will be used. is_visible (bool) – If False, the mesh will not be rendered. poses ((n,4,4) float) – Array of 4x4 transformation matrices for instancing this object. wireframe (bool) – If True, the mesh will be rendered as a wireframe object smooth (bool) – If True, the mesh will be rendered with interpolated vertex normals. Otherwise, the mesh edges will stay sharp.
Returns:	mesh – The created mesh.
Return type:	`Mesh`
