v0.1.0 — The Viewport

Forge v0.1.0 — The Viewport

A cross-platform 2D CAD viewport with ECS-backed geometry, command-driven interaction, and a 60fps wgpu render pipeline.

Features

Render Pipeline (wgpu 29)

• wgpu-based 2D render pipeline with orthographic camera
• Grid renderer with major/minor lines, axis markers, and lazy regeneration on ≥10% camera shift
• Entity renderer with dedicated WGSL pipelines for Line, Circle, Arc, and Polyline primitives
• Surface loss recovery and window resize handling

Entity-Component System (hecs 0.10)

• ECS geometry store with LineData, CircleData, ArcData, PolylineData components
• Singleton resources: CameraState, GridConfig, InputState

Command System (nom 8)

• Interactive LINE command with buffer-then-commit design and undo support
• Full command parsers for LINE, CIRCLE, ARC, and PLINE (30+ parser tests)
• CIRCLE/ARC/PLINE stubs ready for v0.2.0 implementation

Input (winit 0.30)

• Mouse/keyboard handling with camera pan (middle-drag) and zoom (scroll wheel)
• Click dispatch to active commands for point picking
• 8 unit tests covering pan/zoom math and clamping

UI (egui 0.34)

• Status bar with live coordinates, zoom %, and version string
• Command-line text input with history (1000-entry cap)
• Toolbar and property inspector stubs (ready for v0.2.0)
