about the mouse thing

[irisred]

I saw there was a circle at where the mouse moved or click, I use other controller to do the mouse thing, but could you tell me how to add the circle to my controller? there are the X-position and Y-position on the page of my controller, which part of the code add the circle at the position? thanks

It's here : https://github.com/stephomi/sculptgl/blob/master/src/mesh/Selection.js

It only displays the circle while we are picking the mesh. And if we sculpt, I only show the small dot.

I saw that, what about the sketchfab? where is the circle of it defined? https://github.com/sketchfab/sculptgl

Ah... it was different back then.
It was in the shader :
https://github.com/sketchfab/sculptgl/blob/master/shaders/reflection.frag#L17-L20

[irisred]

is the js function called "picking", or just loadshaders function load the .frag file?
like here:https://github.com/sketchfab/sculptgl/blob/master/sculptgl.js#L186-L209
if I use another controller just like touch pen or Leap Motion, can the circle also be displayed?

[stephomi]

It's the shader that draw the circle...
It uses the center of the circle here
And its radius here

The picking is the stuffs that check what is under your cursor by casting a ray.
It's done here in the mousemove event.

Keep in mind that the sculptfab version is almost 2 years old and that I don't maintain it.
You should probably use the latest verson :).
