How to adjust display size of points when showing a PointCloud?

See original GitHub issue

Hi,

Thanks for this amazing tool!

How can I adjust the size of points when I show a PointCloud? By default the points are very small, which makes them very difficult to see:

m = trimesh.load('teapot.stl')
points = m.sample(1000)
colours = np.random.randint(low=0, high=255, size=(1000, 3))
cloud = trimesh.PointCloud(points, colors=colours)
trimesh.Scene(cloud).show()

Hi,

I see the new release incorporates this fix, thanks!

I’m having trouble working out how to pass my desired point size. I tried show(line_settings={'point_size':100}):

m = trimesh.load('teapot.stl')
points = m.sample(1000)
colours = np.random.randint(low=0, high=255, size=(1000, 3))
cloud = trimesh.PointCloud(points, colors=colours)
trimesh.Scene(cloud).show(line_settings={'point_size':100})

but it doesn’t have any effect. Any help would be much appreciated 😃

No worries I run into this too on high-DPI machines. I made it settable in https://github.com/mikedh/trimesh/pull/997/commits/6913a7ef0031695c5da3287cb3a8a9cc842cde27 and also set the default to a fraction of resolution.

Thanks for the report!
