Isometric Design

"The architect's view. A parallel projection where depth is constant and parallel lines never converge."

When to Use

Use this sub-style when the user's request matches the aesthetic described above. This is a child reference of the design-it skill and is not meant to be triggered directly.

Core Principles

1. Parallel Lines: Unlike true 3D, isometric projection has no vanishing point. Everything is viewed from an exact 30-degree angle.
2. Top-Down, Angled View: The classic "SimCity" perspective.
3. Blocky Architecture: UI elements often look like city blocks or stacked tiles.

Visual DNA

• Colors: Warm Tech or Earth-Grounded Elegance. Isometric designs often look like physical models, so slightly muted, realistic colors work well.
• Typography: Keep text flat to the screen, or map it perfectly to the isometric planes (top, left, right).
• Shadows: Hard, long drop shadows cast at an exact angle (usually -45 or 45 degrees).

Web Implementation

• CSS transforms are perfect for this. Combine rotateX(60deg) and rotateZ(-45deg).
• CSS Example:

.isometric-grid {
  /* The foundation */
  transform-style: preserve-3d;
  transform: rotateX(60deg) rotateZ(-45deg);
}

.iso-block {
  width: 100px;
  height: 100px;
  background-color: var(--secondary-base);
  position: relative;
  transition: transform 0.3s;
}

/* Creating the 3D block with pseudo-elements */
.iso-block::before {
  content: '';
  position: absolute;
  width: 20px; /* Depth */
  height: 100%;
  background-color: var(--primary-text); /* Darker shade for side */
  right: 100%;
  transform-origin: right;
  transform: skewY(-45deg);
}

.iso-block::after {
  content: '';
  position: absolute;
  width: 100%;
  height: 20px; /* Depth */
  background-color: var(--cta-highlight); /* Lightest shade for top/bottom */
  top: 100%;
  transform-origin: top;
  transform: skewX(-45deg);
}

.iso-block:hover {
  transform: translateZ(20px) translate(-10px, -10px);
}

App Implementation

SwiftUI

struct IsometricView: View {
    var body: some View {
        ZStack {
            Color.white.ignoresSafeArea()
            
            // Isometric Stack
            VStack(spacing: 0) {
                // Top layer
                Rectangle()
                    .fill(Color.blue)
                    .frame(width: 150, height: 150)
                    .overlay(Text("TOP").foregroundColor(.white))
                
                // Shadow simulation
                Rectangle()
                    .fill(Color.black.opacity(0.2))
                    .frame(width: 150, height: 20)
            }
            // The exact 3D transformations for Isometric projection
            .rotationEffect(.degrees(-45))
            .rotation3DEffect(.degrees(60), axis: (x: 1, y: 0, z: 0))
        }
    }
}

• SwiftUI's .rotation3DEffect makes this surprisingly easy. Rotate Z by -45 degrees first (via .rotationEffect), then rotate X by 60 degrees.
• You can stack multiple views along the Z-axis (or simulate it with Y offsets before the 3D rotation) to create towering isometric city blocks.

Flutter

import 'dart:math';

class IsometricScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.white,
      body: Center(
        child: Transform(
          // The Isometric Matrix Math
          alignment: FractionalOffset.center,
          transform: Matrix4.identity()
            ..setEntry(3, 2, 0.001) // perspective
            ..rotateX(pi / 3) // 60 degrees
            ..rotateZ(-pi / 4), // -45 degrees
          child: Container(
            width: 150,
            height: 150,
            decoration: BoxDecoration(
              color: Colors.blue,
              boxShadow: [
                // Hard isometric drop shadow
                BoxShadow(
                  color: Colors.black.withOpacity(0.3),
                  offset: const Offset(20, 20),
                  blurRadius: 0, // No blur for isometric
                ),
              ],
            ),
            child: const Center(child: Text('ISO BLOCK', style: TextStyle(color: Colors.white))),
          ),
        ),
      ),
    );
  }
}

• Transform with Matrix4 is required in Flutter. Applying rotateX and rotateZ yields the classic isometric grid.
