Bad rendering of Point Cloud


(Tai Pinc) #1

Hello,

Recently there seems to have been a change in the way Sketchfab is showing point cloud models. The points are not constantly visible and they seem to change size and appearance. Perhaps this is an anti-aliasing issue?

Thanks

Tai

It's probably an antialiasing indeed.

To be sure can you provide me with a screenshot (without tweaking the camera) of https://sketchfab.com/models/8029d994ad6947af85da8839565ad13a/embed?autostart=1&cameraEye=-7.68,49.81,4.79&cameraTarget=-7.47,50.98,4.80 ?

Thanks!

Is it possible for me to turn off antialiasing ?

This one is a very good example (at https://sketchfab.com/models/aae9ca65c6af41f6a017c64aefc93737)

Look at the points in the upper-right corner. all dots should be equal size and approximately equal colour/brightness. Instead it just looks very noisy.
In denser parts it looks like weird patterns, sometimes sharp and sometimes little blurry.

Ok, we decided to disable the antialiasing if there's no triangles in the scene.
We'll ping you back when it's done and live.

Yay! Thank you very much :smile:
