Making progress on underwater scenes ( but still more to come :) ) !

[Original scan](https://skfb.ly/6suDz) from @ariosgeo, and inspiration from [Il Cristo degli Abissi](https://goo.gl/RU5PtJ), a submerged statue of Jesus in Italy.

**Modeling**:

* The scan was remeshed with [mmgs](http://mmgtools.org) from 500k verts to 7k, keeping the face and hands at a higher resolution.
* The ocean surface and ground were created with blender's ocean modifier.
* Light shafts are simply a randomized array of elongated planes.
* The fish is a lowpoly model ( a 30s model ).
* A particle system was created for fish instances, with force fields applied (boids physics, vortex, attraction force and collision on the statue)

**Texturing/lighting**:

* Mix of concrete and coral on the statue
* Sand on the ground
* Nothing on the sea surface
* Radial opacity for ground and surface
* Voronoi textures baked as emission on the statue and the ground, to simulate the light deformation through water
* Lots of color processing

Christ of the Abyss

As it appears to be a trend, a small WIP diorama ([Nice one here!](https://skfb.ly/6xvV6)) just to try out some lighting technique for an incoming model (not a WIP I hope).

The refractive "box" around the model is just eye-candy, what was really of interest to me was to get an idea about bubbles (spheres with an emissive material coupled with dithering transparency), sun rays (elongated planes with blending opacity and a light emission to them) and the ground lights (not done well here, but basically voronoi textures to simulate the effect of waves on the light, baked on the ground model).

The ground is a quick and ugly dyntopo sculpt done in blender, while the little fish are just a particle system set with a lowpoly mesh as render object.

A nice point to spend time on will be the ocean surface, to do with the appropriate modifier in blender, and a refractive/small-scale-roughness/foamy-at-the-edges material.

Plus, I should try to animate rays, bubbles and fish (as boids) to give it a living touch.

Abstract Design

Li — Experiment A: Voronoi Hopf (PAPP V5) is a watertight high-relief disc where 4D polychoron vertices, projected through Hopf (S³→S²), become Voronoi seeds on the disc. 

A furthest-point subsampling selects 150 seeds from the full 42,852 projected vertices (7 Li polychora), producing a hard, binary tessellation: every surface point belongs to exactly one cell. 

Height is built from (1) cell plateau driven by the source polychoron’s β* (normalized to ~0.5–0.9), (2) surface roughness from the Pythagorean ratio a/c, (3) geological cell tilt, and (4) sharp broken valleys at boundaries using a sigmoid transition (depth 0.35, width 0.06). 

Adds Pythagorean frequency modulation and Hopf fiber rings (n=1–5).

Mesh: 57,170 verts / 114,336 faces, closed manifold χ=2. Z range [−0.110, 1.051]. Unique colors (3dp): 22,344.

06 — Abyssal Bowl

Concave ceremonial plate. 280-seed Voronoi ripples network with Gaussian fault walls, 6-wave coral reef crust texture, double counter-rotating logarithmic vortex poles, and kite network diagonals at 54°/126°. PAPP 4D hull-first mode ranks each plate by φ-elevation. Deep ocean palette — navy body, turquoise ripples, bioluminescent cyan at vortex cores. 66,770 vertices, 133,536 faces, χ=2, closed manifold.

Prototype 06/12 Abyssal Bowl | PAPP

A layered generative object built from a manifold mesh shaped through a Voronoi field and a 7-plane structure, then modulated by a 19-circle Flower of Life pattern.
The surface combines plateaus, seams, ridges, and wells into a single optical architecture, where the floral field is not simply decorative but embedded in the geometry of the piece.

This version uses a dense mesh with 61,058 vertices and 122,112 faces, preserving a clean closed topology (χ = 2). The result feels like an ancient mystic mosaic: splitted grout, mineral-like plateaus, and symbolic interference patterns emerging across the surface.

A fusion of computational geometry, sacred-pattern logic, and sculptural relief.

Li A - Voronoi Planes/Flower 19 Mystic V2| PAPP

These are some ice cubes I created. Below are the components of what makes a cube of ice:
– The displacement is based on the difference between F2 and F1 voronoi, fractalized (scale is repeatedly multiplied by constant "n", texture is also repeatedly divided by n, all passes are added together)
– The normal map is just Improved Perlin Noise (16 octaves)
Materials:
– Glass (Transmissive)
    – Refraction (IOR = 1.330)
    – Glossy
    –Mix based on fresnel reflectance (i_0 + (1-i_0)(1-cos(incoming angle))^5)
– Volumetric
    – Very little absorption
    – A little more but still little scattering
These models can be used, as long as ***credit is given***
