Full Version: Cross Hatching experiment

Hi Wayne, here you go this one is the cross hatching all by itself, no edges or shading underneath.



Here is the same hatching with silhouettes added:

Thank you!

This is a wonderful collection of effects! I look forward to being able to use it as it does a really nice job of illustrating curvature. I particularly like the artistic nature of the hatching. Well done Michael!!

Hi Michael

Looks great with the silhouettes added, really handy.

---

So it's that sort of effect that you want but made in Moi3D ?

---

Hi James, yeah I wasn't sure if the sketchy cross hatching would combine ok with the exact silhouettes but it seems fine together.

hi Pilou,

re:

Yes, similar but with vector lines and curves being output, not as an image processing effect.

Ok! :)
these hatching must also following the lighting of the object or must be isotropic ?
(from your examples seems isotropic)

It's possible to do either.

The ones here adapt to lighting and have denser lines (smaller spacing) where the lighting is dark:

This one does not respond to lighting:

That will be an option that you will be able to set.

ok...

Else in theory Flow function can't be used ?

Hi Pilou,

re:

Not if you want it to look like real hatching - the pattern flowed on a sphere will be compressed at the pole areas and wider at the equator.

- Michael

---

Yes but you can make some Flow after a rotation of the sphere!
Sure the hatching will be not ultra regular but...

---

Hi Pilou, that's too dense with too many lines crossing each other. It should only have 2 lines crossing each other at any single point like this:

Hi Michael,
Congrats!!
Maybe look at a "max length" type of value that can get rid of the "tidbits"... the little "outlying flyers"....

---

Thanks Burr! Yup I was also thinking of a minimum cutoff size parameter to cull stubby pieces.

- Michael

---

Righteous!

I feel your excitement! Like it's a long lost pal...

I wish you more of those to come this year!

---

Thanks Burr, yup it's true I'm pretty excited!!

Failed test

Getting more under control. Here with shading aware spacing and breaks at specular highlights.

Hi Michael!

...very interesting!
Keep it rolling :)
