# Rendering: 3d-isometric

Isometric 3D forms with controlled depth — boxes, layers, devices, stacks rendered in 30°/30°/30° projection. The dominant choice for tech architecture, product structure, and system composition visuals in modern decks.

## 1. Style paragraph (paste-ready, 105 words)

> 3D isometric illustration with clean geometric forms rendered in true 30°/30°/30° projection. All edges are crisp and uniform — no perspective distortion, no vanishing points. Surfaces use flat solid fills with subtle tonal shifts (a single darker shade for shadowed faces, ~15% darker than the light-facing face) to convey volume without painterly rendering. Edges may have thin uniform outlines or use direct color contrast. Composition emphasizes stackable, modular forms — boxes, blocks, layers, cards floating in arrangement. Soft 8% drop shadows beneath floating elements anchor them in space. Overall feel is technical, structured, contemporary — common in SaaS product diagrams, cloud architecture visuals, system component breakdowns.

## 2. Line, texture, depth

| Aspect | Treatment |
|---|---|
| Line quality | Thin uniform edges, or no edges relying on color contrast |
| Texture | None on surfaces — flat fills |
| Depth | True isometric projection (30°/30°/30°), tonal shading on shadowed faces, optional 8% drop shadow under floating elements |
| Material | Flat with tonal shading — not glossy, not photorealistic |
| Mood | Technical, modular, contemporary |

## 3. Using the deck's HEX values

- Primary HEX: main block face fills (the "lit" face)
- Secondary HEX: background field
- Accent HEX: a single highlighted block or connecting line
- Shadowed faces: ~15% darker shade of the primary (automatic from prompt phrasing — no extra HEX needed)

**Snippet A — half-page system architecture, text_policy: none**

> 3D isometric illustration in true 30°/30°/30° projection. Three stacked blocks rise from a clean isometric plane — a wide foundation block in primary deep blue `#1E40AF`, a medium block in slightly darker blue stacked on top, and a smaller block on top of that. To the right, two floating cards in the same blue family hover above the stack, connected by thin diagonal lines. The "lit" faces of all blocks use the primary blue; the shadowed faces use a 15% darker tonal shift of the same blue. Accent gold `#D4AF37` appears as one thin line connecting the top block to a floating card. Background is calm secondary `#F8FAFC`. Soft 8% drop shadows beneath the floating cards. Composed as a 600×500 half-page block with 15% inner padding. NO text, no labels, no numbers anywhere in the image. Color values are rendering guidance only.
