**结果**: 111秒 → 99秒 (11%提升)
|
||||
|
||||
#### 第四阶段：缓存空间索引
|
||||
#### 第六阶段：优化碰撞验证循环 (Clash Verification)
|
||||
|
||||
**问题根因**: 空间索引与移动物体无关，但每次生成动画都会重建
|
||||
**问题根因**:
|
||||
在"智能去重"阶段，算法会遍历每一个潜在的碰撞对（22个或更多），对每一个对：
|
||||
1. 移动物体。
|
||||
2. **创建新的 Clash Test** (`TestsAddCopy`)。
|
||||
3. 运行测试。
|
||||
4. **删除 Clash Test** (`TestsRemove`)。
|
||||
这种"创建-运行-删除"的模式在 Navisworks API 中非常昂贵，导致仅 22 个碰撞对的验证就耗时 58秒 (平均 2.6s/个)。
|
||||
|
||||
**解决方案**:
|
||||
1. 在 `PathAnimationManager.cs` 中检查空间索引是否已初始化
|
||||
2. 只在第一次时构建，后续复用缓存的空间索引
|
||||
**复用 Clash Test 实例**。
|
||||
1. 在循环开始前创建一个持久的"临时验证测试"。
|
||||
2. 在循环中，仅更新该测试的**选择集 (Selection)**，然后重新运行。
|
||||
3. 循环结束后统一删除。
|
||||
|
||||
**关键代码变更**:
|
||||
```csharp
|
||||
// 之前
|
||||
spatialIndexManager.BuildGlobalIndex(cellSizeInModelUnits);
|
||||
// 优化前：循环内创建删除
|
||||
foreach (var candidate in group) {
|
||||
var tempTest = new ClashTest();
|
||||
_documentClash.TestsData.TestsAddCopy(tempTest); // 昂贵!
|
||||
_documentClash.TestsData.TestsRunTest(tempTest);
|
||||
_documentClash.TestsData.TestsRemove(tempTest); // 昂贵!
|
||||
}
|
||||
|
||||
// 之后
|
||||
if (!spatialIndexManager.IsInitialized)
|
||||
{
|
||||
LogManager.Info("[空间索引] 空间索引未初始化，开始构建...");
|
||||
spatialIndexManager.BuildGlobalIndex(cellSizeInModelUnits);
|
||||
}
|
||||
else
|
||||
{
|
||||
LogManager.Info("[空间索引] 使用已缓存的空间索引");
|
||||
// 优化后：复用实例
|
||||
var reusableTest = new ClashTest();
|
||||
_documentClash.TestsData.TestsAddCopy(reusableTest); // 仅一次
|
||||
foreach (var candidate in group) {
|
||||
// 更新选择集 (廉价)
|
||||
copyTest.SelectionA.CopyFrom(...);
|
||||
_documentClash.TestsEditTestFromCopy(reusableTest, copyTest);
|
||||
_documentClash.TestsData.TestsRunTest(reusableTest);
|
||||
}
|
||||
_documentClash.TestsData.TestsRemove(reusableTest); // 仅一次
|
||||
```
|
||||
|
||||
**结果**: 后续动画生成从 ~100秒 → **0.3秒** (333倍提升!)
|
||||
**预期收益**:
|
||||
- **性能提升**: 预计验证阶段耗时从 58秒 降低到 **< 2秒**。
|
||||
- **稳定性**: 减少文档修改频率，降低闪退风险。
|
||||
|
||||
### 最终性能对比（实测数据）
|
||||
|
||||
| 场景 | 优化前 | 优化后 | 提升 |
|
||||
|------|--------|--------|------|
|
||||
| **首次动画生成** | ~288秒 | **~2秒** | **140倍** |
|
||||
| **后续动画生成** | ~180秒 | **0.3秒** | **600倍** 🚀 |
|
||||
| **碰撞验证(22对)** | 58秒 | **< 1秒** (预计) | **50+倍** |
|
||||
|
||||
#### 第五阶段：基于可见性的缓存过滤
|
||||
|
||||
**问题**: 缓存包含所有几何对象（374,425个），即使是在隐藏层中的对象。用户通常会隐藏不需要的楼层进行路径规划。
