Examples

Examples

Every demo compiles with pwe compile … -o out.pweb, then pwe present out.pweb. Sources live in cli/examples/.

Demo	What it is
humanoid.pwe	A 62-part humanoid walking — capsule limbs, facial detail, knuckled fingers.
robot.pwe	A 2-link robot arm waving, driven by std/robotics forward kinematics.
shapes.pwe	Custom shapes: composites, a convex octahedron, an explicit-face gem, an extruded SVG star.
wave3d.pwe	A 3D wave radiating through a cube — a translucent energy-coloured shell that expands and fades.
acoustics.pwe	2-D sound from a driven monopole; probes register arrival delay and level in dB.
solar.pwe	The solar system, live: 8 planets + Moon, orbiting and self-rotating.
flock.pwe	A flock coalescing and aligning via neighbourhood queries.
domains.pwe	One probe under a damped spring while radiatively cooling — forces + thermal + EM + chemistry composed.
spring/spring.pwe	Multi-file modules, parameters, units, and scheduled events (--param k=16).
wave.pwe	A sine standing wave on a 1-D line, drawn as an energy-coloured curve.
heat.pwe	Heat diffusion on a 2-D grid (an unrolled Gauss–Seidel sweep).
bounce.pwe	The classic: gravity + ground contact with restitution.

Run one

cargo build --release -p pwe-cli
./target/release/pwe compile cli/examples/solar.pwe -o solar.pweb
./target/release/pwe present solar.pweb --port 8000

Override parameters without recompiling:

./target/release/pwe present spring.pweb --port 8000 --param k=16

Reading the output

The viewer renders entities from their own declaration — shape, size, color, opacity, glow, label — and fields as an isosurface (2D/3D) or a curve (1D). Controls: ⟳ Restart, ⏸ Pause / ▶ Resume, 🏷 Labels.

Presentation-only fields never touch simulation state, so what you see can never perturb what you prove.
