Parametric surfaces + shells

[lycium]

You're gonna need more polygons in this scene, I still see terminator artifacts

no images to show here, yet...

[Whaat]

lovin' these tests, ono. Give us more!

[OnoSendai]

will do, tmrw

[StompinTom]

Lookin' good!

[rgigante]

Thumb up! Great seeing first unbiased to implement native paametrics. NURBS to come?

[Zom-B]

That looks really nice Ono, feed us with more!
Normal smoothing doesn't seem to kick in here

Now please melt those all together with some metaball algo

[OnoSendai]

Scattered pebbles and shells.
50K pebbles and 100 shells.
Pebble and shell geometry are done with parametric surfaces.

NURBS will be implemented some day

Another one:

Sunset beach with narrower DOF.

Niiice !

I don't know if that's possible already but it would be useful to use a displaced mesh as scattering surface, ie displace a terrain then scatter peebles over. Adding details to the detail.

An alternative would be to be able to modify the peebles position by a shader (displacement for instance). The scattering would be generated before subdivisions but matching them.

Sunset beach with narrower DOF.

Ground just needs a bump texture (FBM?) and it would be perfect Can you render one with 5M pebbles? Like, covering the ground completely?

The scattered pebbles are already scattered over the parametric surface, which is already displaced. So the scattering does follow the detailed surface.

Well, this one already has 1M small pebbles

Dare you to put 10M
