Are you interested in the vector, in world space, that points down the screen (in z)? In that case you could do something like: ```py ndc = la.vec_transform(world_pos, camera.camera_matrix) ndc1...

I had another look (sorry it took so long). The only thing standing in the way of a merge (IMO) is the geometry API. The API of the geometry object...

This works (tested briefly) ```py import numpy as np from pygfx.cameras._perspective import fov_distance_factor extent = 0.5 * (camera.width + camera.height) distance = extent * fov_distance_factor(camera.fov) looking_at = camera.world.position + camera.world.forward...

I think basing the default on what is in the plot may be confusing. E.g. what if you initially have only lines, but add an image later? It's already quite...
