normalize uv suface maps Tweet

[A.Lopez]

hello,
there is some magical way to normalize the surface's UV maps (OSL, script, Lua)?
I mean to maintain the surface's UV direction but to have ALL the UV numbers/letters of the same dimensions as in the box projection?
thanks,
R.

Hi - what pass are you showing above please? It doesn't look like a Normals pass. If it's the UV pass, then you will need to UV map the geometry in Rhino (rather than the plugin).

Thanks

Hi Paul,
Yes it’s the Uv mapping. I was hoping that octane had some projection (osl, script, lua ) that could normalize the UV map, I mean uniforming the scale maintaining the UV coordinates. Rhino not have it at the moment.

Hi - Octane can possibly do what you want, however it's over my level of ability, sorry.

ok,
thanks anyway,

Some OSL developer genius could help with this?
It could be great...

Could you clarify what you mean by "uniforming the scale maintaining the UV coordinates." with an example?

Yes, of course!
First of all, I've sent the same question to McNeel of Rhinoceros that I use for modelling and I've found the first genius... A developer named Jussi that as already created a plugin for Rhino to UnifyUVWRepeat (as he called the plugin), doing about what I need. In the first image, you can see the UV map as the object created in Rhino have as default projection. In the second, in just one click using this plugin, I've unified all the UV map scales (leaving the default correct directions, giving each square the dimension I want in the model unit! I mean I can decide the dimensions of each square. The way the plugin works is that it transforms only the UV map scale.
He told me that this is the first prototype. There is some issue to solve, for example, the dimension I used to define the square doesn't give a precise result (I've put 10 and I've received about 12.5 cm) and in some case, using complicated command to make 3d surfaces in Rhino, the squares are rectangles. But as a prototype, it's already absolutely useful...
About Octane, if it could be able to have a UV projection that does this in some way, it could be great.
Sorry to have written a "Divina Commedia" but I would like to be more clear as possible.

I think what he means is Texel Density.
