… Field of View, Path Following, and Advanced Camera Animation
…atting - Add showcase demos for Advanced Camera Animation, Path Following, Data Visualization, Roadmap Mode, and Field of View - Synchronize hardware frame loops to VSYNC and improve touch-fade UX - Format codebase using spotless to adhere to 4-space ktlint rules
… auto-fade, and literate docs (#54) * Enhance Advanced Camera Animation and Path Following samples - Advanced Camera Animation: - Add modular step animation pipeline (FlyToStep, OrbitStep, DwellStep, FlyAroundStep, KeyframeStep). - Add high-altitude San Francisco starting camera view. - Implement full reset and continuous orbit support. - Sync Java, Kotlin, and Jetpack Compose implementations. - Path Following: - Implement two-polyline progress tracking with wide blue base route (lower z-index) and narrow purple progress route (higher z-index). - Use in-place fixed polyline IDs to eliminate rendering flickering. - Default altitude mode to 'Clamp to Ground' with support for Relative to Ground, Relative to Mesh, and Absolute. - Add dynamic path height slider to avoid z-fighting with terrain. - Add collapsible control panel with explicit collapse/expand button, auto-slide dismissal, and subtle idle opacity. - Extract all hardcoded strings into strings.xml resources. - Align Java and Kotlin implementations. * feat(fieldofview,datavisualization): polish FOV and Data Visualization with collapsible cards and literate docs * feat(roadmapmode): polish Roadmap Mode with collapsible header and literate docs * feat(routes): polish Routes API sample with collapsible control panel, auto-fade, and literate docs * docs(samples): augment literate comments explaining 3D coordinates, extrusion, and smoothing * build: untrack and gitignore gradle-daemon-jvm.properties * docs: update copyright headers to 2026 for camera animation step classes * fix(samples): address PR review feedback on animation timing, tour resume, onPause, and TransitionManager collapse

📋 Summary
This PR enhances the Path Following and Advanced Camera Animation sample features across Kotlin Views, Java Views, and Jetpack Compose with occlusion visualization toggles, dual-polyline rendering, dynamic altitude modes, 4 selectable camera animation approaches, and Compose parity.
🚀 Key Features & Improvements
1. 🛣️ Path Following (
PathFollowingActivity)drawsOccludedSegments):switch_draws_occluded_segments) in Kotlin, Java, and Compose allowing polylines to render through or behind 3D terrain and building geometry.#4285F4, 16dp,zIndex = 1).#9C27B0, 8dp,zIndex = 2) that extends in real-time as the route is traversed.path_following_static_route,path_following_progress_route) eliminate rendering flicker.PathFollowingActivity.ktwith dual-polyline rendering, 4 Altitude Modes selector (CLAMP_TO_GROUND,RELATIVE_TO_GROUND,RELATIVE_TO_MESH,ABSOLUTE), Path Height slider (0–10m), aligned SF Urban & CA Rural datasets, and collapsible UI with idle auto-fade.2. 🎬 Advanced Camera Animation (
AdvancedCameraAnimationActivity)rg_animation_approach) to showcase 4 distinct camera animation techniques in Kotlin and Java:flyTo: Native Maps 3D camera transition.control_panel_advanced_animation.xmlandstrings.xmlwith approach selector radio buttons, tour step cards, and status indicators.3. 🧪 Testing & Verification
PathFollowingVisualTest.ktinComposeDemosto match Kotlin and Java visual regression coverage with the Gemini API testing pipeline.
