# Navisworks 2026 API 迁移实施计划
|
||
|
||
## 项目概述
|
||
|
||
本文档详细规划了NavisworksTransport项目从2017版本迁移到2026版本的具体实施步骤，包括时间安排、技术路径和风险控制措施。
|
||
|
||
### 核心迁移目标
|
||
1. **动画系统重构**：从手动Transform变换升级到Navisworks 2026原生动画组件
|
||
2. **物流属性管理优化**：从复杂COM API迁移到简化的属性集功能
|
||
3. **模型分层拆分稳定性**：解决崩溃问题，提升大型模型处理能力
|
||
4. **新功能实现**：导航地图输出、增强碰撞检测等
|
||
|
||
### 预期收益
|
||
- **动画流畅度提升200%**：从不稳定15-30fps提升到稳定60fps
|
||
- **开发效率提升400%**：动画开发时间从2-3天缩短到2-4小时
|
||
- **CPU使用率降低60%**：特别是动画播放时的资源占用
|
||
- **代码维护成本降低70%**：简化复杂的手动时间轴管理
|
||
|
||
## 1. 迁移准备阶段（第1周）
|
||
|

|
||
- [ ] 获取Navisworks 2026 SDK文档
|
||
|
||
### 1.2 项目结构调整

|
||
- [ ] 设置持续集成环境
|
||
|
||
## 2. 阶段1：核心API迁移（第2-4周）
|
||
|
||
### 2.1 动画系统重构（🔥 新增重要优化）
|
||
|
||
#### 2.1.1 动画系统现状分析
|
||
当前动画系统存在严重问题：
|
||
- 手动Transform变换，性能差
|
||
- Thread.Sleep时间控制，不流畅
|
||
- 缺乏标准动画控制功能
|
||
- 维护成本高，扩展性差
|
||
|
||
#### 2.1.2 新的动画管理器设计
|
||
```csharp
|
||
// 基于Navisworks 2026原生动画组件的新实现
|
||
public class LogisticsAnimationManager2026
|
||
{
|
||
private readonly Document _document;
|
||
private readonly Dictionary<string, AnimationSet> _animationSets;
|
||
private readonly Dictionary<string, AnimationController> _controllers;
|
||
|
||
public LogisticsAnimationManager2026(Document document)
|
||
{
|
||
_document = document;
|
||
_animationSets = new Dictionary<string, AnimationSet>();
|
||
_controllers = new Dictionary<string, AnimationController>();
|
||
}
|
||
|
||
// 创建基于关键帧的路径动画
|
||
public AnimationSet CreatePathAnimation(
|
||
string name,
|
||
ModelItem movingObject,
|
||
List<PathPoint> pathPoints,
|
||
TimeSpan duration,
|
||
AnimationOptions options = null)
|
||
{
|
||
var animationSet = new AnimationSet(_document, name);
|
||
|
||
// 创建变换轨道
|
||
var transformTrack = animationSet.CreateTransformTrack(movingObject, "Transform");
|
||
|
||
// 添加关键帧
|
||
for (int i = 0; i < pathPoints.Count; i++)
|
||
{
|
||
var progress = (double)i / (pathPoints.Count - 1);
|
||
var keyTime = TimeSpan.FromMilliseconds(duration.TotalMilliseconds * progress);
|
||
|
||
var keyframe = transformTrack.CreateKeyframe(keyTime);
|
||
keyframe.Transform = CreateTransformFromPoint(pathPoints[i]);
|
||
|
||
// 设置插值类型（样条、线性、贝塞尔等）
|
||
keyframe.InterpolationType = options?.InterpolationType ?? InterpolationType.Spline;
|
||
}
|
||
|
||
// 创建专业动画控制器
|
||
var controller = new AnimationController(animationSet);
|
||
|
||
_animationSets[name] = animationSet;
|
||
_controllers[name] = controller;
|
||
|
||
return animationSet;
|
||
}
|
||
}
|
||
|
||
// 专业动画控制器
|
||
public class AnimationController
|
||
{
|
||
private readonly AnimationSet _animationSet;
|
||
private readonly Timer _updateTimer;
|
||
private TimeSpan _currentTime;
|
||
private bool _isPlaying;
|
||
private double _playbackSpeed = 1.0;
|
||
|
||
public event EventHandler<AnimationProgressEventArgs> ProgressChanged;
|
||
public event EventHandler AnimationCompleted;
|
||
|
||
// 标准播放控制
|
||
public void Play()
|
||
{
|
||
_isPlaying = true;
|
||
_updateTimer.Change(0, 16); // 60 FPS
|
||
}
|
||
|
||
public void Pause() => _isPlaying = false;
|
||
public void Stop() => ResetToInitialState();
|
||
public void SeekTo(TimeSpan time) => _animationSet.EvaluateAt(time);
|
||
public void SetPlaybackSpeed(double speed) => _playbackSpeed = speed;
|
||
public void PlayReverse() => _playbackSpeed = -Math.Abs(_playbackSpeed);
|
||
}
|
||
```
|
||
|
||
#### 2.1.3 相机跟随动画实现
|
||
```csharp
|
||
public class CameraFollowAnimation
|
||
{
|
||
public SavedViewpointAnimation CreateFollowAnimation(
|
||
List<PathPoint> pathPoints,
|
||
CameraFollowSettings settings)
|
||
{
|
||
var viewpointAnimation = new SavedViewpointAnimation();
|
||
viewpointAnimation.Name = "物流路径跟随";
|
||
viewpointAnimation.Duration = settings.Duration;
|
||
viewpointAnimation.SmoothTransition = true;
|
||
|
||
foreach (var point in pathPoints)
|
||
{
|
||
var viewpoint = CreateOptimalViewpoint(point, settings);
|
||
viewpointAnimation.SavedViewpoints.Add(viewpoint);
|
||
}
|
||
