Meshes

The Panopti Mesh object represents a triangular surface mesh. To add a mesh to your scene:

import panopti
import trimesh # just for io
import numpy as np

viewer = panopti.connect(server_url="http://localhost:8080", viewer_id='client')

mesh = trimesh.load('mesh.obj')
verts = mesh.vertices   # (V, 3) ndarray
faces = mesh.faces      # (F, 3) ndarray 

viewer.add_mesh(
    vertices=verts,
    faces=faces,
    name="MyMesh"
)

BaseViewer.add_mesh

add_mesh

Adds a Mesh object to the viewer.

Parameters:

Name	Type	Description	Default
vertices	ndarray	(V, 3) array of vertex coordinates.	required
faces	ndarray	(F, 3) array of face indices.	required
name	str	Name for the mesh.	required
visible	bool	Whether the mesh is visible.	True
position	Union[Tuple[float, float, float], ndarray]	Position of the mesh (XYZ).	(0, 0, 0)
rotation	Union[Tuple[float, float, float], ndarray]	Rotation of the mesh (XYZ).	(0, 0, 0)
scale	Union[Tuple[float, float, float], ndarray]	Scale of the mesh in (XYZ).	(1.0, 1.0, 1.0)
vertex_colors	ndarray	(V, 3) array of vertex colors.	None
face_colors	ndarray	(F, 3) array of face colors.	None
material	Optional[Any]	Panopti material object.	None

Returns:

Name	Type	Description
Mesh	Mesh	The created panopti mesh object.

Mesh.update(**kwargs)

update

Updates this mesh's attributes and propagate updates to the viewer.

Example:

mesh = viewer.get('MyMesh')
mesh.update(vertices=new_verts, material=new_material)

Mesh.delete()

delete

Deletes this mesh from the viewer.

Mesh.trans_mat property

trans_mat

Returns the 4x4 transformation matrix corresponding to the object's position, rotation, and scale in the viewer.

Mesh.viewer_verts property

viewer_verts

Returns the Mesh's vertices under the transformation given by trans_mat.
