I am running a program and I want to render and display a 3D bunny. Therefore we use pyrender and trimesh. In my university class they showed a trick so that the rendering is running on a side thread so that we can still interact with the window and change things. This works for everyone but not for me. Here is my code.
bunny = trimesh.load("/bun_zipper.ply")
mesh = pyrender.Mesh.from_trimesh(bunny)
scene = pyrender.Scene(ambient_light=[.5, .5, .5], bg_color=[0, 0, 0])
node = pyrender.Node(name="Node", mesh=mesh)
scene.add_node((node))
v = pyrender.Viewer(scene,run_in_thread=True)
the problem is here the run_in_thread=True. Without this argument it works fine for me but with that argument I get the following error message:
