Hii, I want to create a line of 1 cm in THREE.Scene.I make a line by passing vertices value of {0,0,0} to {1,0,0} which makes straight horizontal line,But I have a doubt is it a 1 mm or 1 cm line ?? or is it measure in Pixel. Thanks & Regards Gaurav

Hmm… so where do we set that? Can three convert English too? (although this stoopid american has become quite accustomed to working in meters in 3d)

There is no realworld unit relation anywhere besides the physics engine i guess. But using 1:1 meter doesn’t work well with phones and larger distances for the animations/GPU side.

I don’t want to hijack this poor persons thread… but Fyrestar & prisoner849, do guys just work strictly with dynamic geo you are creating programmatically (and thus defining their measurements is a snap), or are you, like myself, working extensively with meshes created in your 3d apps and importing …

You should export everything at the same unit system from your modelling software. Just to make everything proportional. It also might depend on this software, as some have a different system. If i import Blender in C4D the models can be rediculous large or small. The software probably offers a inde…

Thank you very much for the explanation. I won’t likely ever need to work with anything other than meters, but I’m glad I have deeper understanding of this nonetheless, should my needs change.

Notice that when you resize a Three.js application, the height of the viewport affect object sizing, so there isn’t really an absolute size for everything. I’m thinking of how to introduce absolute sizing to Three.js. For starters, figuring this out will begin to help understand how to do that. Ulti…

Have you got the absolute sizing/mapping figured out?

For anybody coming across this post, the “official” answer is that three.js uses SI units, meaning that 1 unit = 1 metre. Even though this is abstract, it’ a good idea to stick to this as much as possible since it will make working with other applications easier.

[image] June_Wang: Have you got the absolute sizing/mapping figured out? Yes I have, for example if you try the following demo and resize the window, you’ll see the “buttons” stay the same size regardless of window size (the shadow and light is rendered with Three.js): That example however…
