Add Turntable Camera Mode for 360° Building Inspection

[snjsomnath]

Feature Request: Turntable Camera Mode

Description

Add a turntable camera mode that allows users to automatically rotate around buildings for comprehensive 360° inspection and presentation purposes.

Current State

The application currently supports:

• Perspective and orthographic camera views via CameraManager
• Manual camera controls (mouse wheel zoom, middle mouse drag pan)
• Static camera positioning and view management

Proposed Feature

Implement a turntable mode that:

• Automatically rotates the camera around the currently selected building or scene center
• Maintains consistent distance and elevation during rotation
• Provides speed controls (slow, medium, fast)
• Can be toggled on/off with keyboard shortcut Y
• Pauses rotation when user interacts with manual controls
• Resumes rotation after a brief delay when manual interaction stops

Technical Implementation

• Extend the existing CameraManager class
• Add turntable state management to camera controls
• Implement smooth orbital rotation with configurable parameters
• Add UI controls in the left toolbar
• Integrate with existing keyboard shortcut system

Suggested Keyboard Shortcut

• Y: Toggle turntable mode on/off (follows existing single-letter pattern like G, S, F, T, R)

UI Integration

• Add turntable toggle button to the left toolbar
• Show turntable status indicator when active
• Add speed control options in building config panel

Use Cases

1. Design Review: Automatically inspect buildings from all angles
2. Presentations: Smooth camera movement for client demos
3. Quality Assurance: Systematic building inspection workflow
4. Export/Documentation: Consistent camera movement for screenshots

Acceptance Criteria

• Turntable mode toggles with Y keyboard shortcut
• Camera smoothly orbits around scene center or selected building
• Manual camera controls (mouse wheel, middle drag) temporarily override turntable
• Speed is adjustable (at least 3 preset speeds)
• Integrates with existing CameraManager without breaking current functionality
• Compatible with both perspective and orthographic camera modes
• No performance impact on 3D rendering

Priority

Medium - Enhancement that improves user experience and design workflow efficiency
