Abstract Geometric City Visualization

A unique graph-based prompt structure for visualizing complex scenes. This example uses mathematical nodes and edges to define layers, materials, and camera settings for a stylized representation of a

gemini

The skill

do this for {argument name="subject" default="Mecca"} : G = (V, E) where:

V = {
  v₁: Torus(radius=R, layers=8, material={argument name="material" default="wood"}),
  v₂: City(landmarks={l₁...lₙ}, scale=1:100),
  v₃: Workshop(tools, bench, lighting),
  v₄: Camera(macro, f/2.8, 45°)
}

E = {
  (v₁, v₂, "surface_embedding"),
  (v₁, v₃, "located_in"),
  (v₁, v₄, "viewed_by"),
  (v₂.landmarks, v₁.layers, "distributed_across")
}

Constraints:
  ∀l ∈ landmarks: position(l) ∈ torus_surface
  ∀layer ∈ layers: wood_grain(layer) ≠ wood_grain(layer+1)
  
Generate(G) → Image

How to install it

Gemini

1. Open Gems → New Gem.
2. Paste the text below into the instructions field.
3. Save. The Gem appears in the sidebar and keeps the instructions
   across conversations.

In Google AI Studio the same text goes in System instructions.
