iOS地图SDK


BMK3DModelOption *option = [[BMK3DModelOption alloc] init];
option.modelName = @"among_us";
option.scale = 1;
option.modelPath = [NSString stringWithFormat:@"%@/Model3D", [NSBundle mainBundle].bundlePath];
_modelOverlay = [BMK3DModelOverlay modelOverlayWithCenterCoordinate:CLLocationCoordinate2DMake(39.914838, 116.40299) option:option];

BMK3DModelOption *option = [[BMK3DModelOption alloc] init];
option.scale = 100;
option.modelName = @"batman";
option.zoomFixed = YES;
option.modelPath = [NSString stringWithFormat:@"%@/Model3D", [NSBundle mainBundle].bundlePath];
_modelBatManOverlay = [BMK3DModelOverlay modelOverlayWithCenterCoordinate:CLLocationCoordinate2DMake(39.914838, 116.40499) option:option];

/**
 向地图View添加Overlay，需要实现BMKMapViewDelegate的-mapView:viewForOverlay:方法
 来生成标注对应的View
 
 @param overlay 要添加的overlay
 */
[_mapView addOverlays:@[self.modelOverlay, self.modelBatManOverlay]];

2. 实现代理方法生成对应的view（BMK3DModelOverlayView）

Objective-C

Swift


#pragma mark - BMKMapViewDelegate
/**
 根据overlay生成对应的BMKOverlayView
 
 @param mapView 地图View
 @param overlay 指定的overlay
 @return 生成的覆盖物View
 */
- (BMKOverlayView *)mapView:(BMKMapView *)mapView viewForOverlay:(id<BMKOverlay>)overlay {
    if ([overlay isKindOfClass:[BMK3DModelOverlay class]]) {
        //初始化一个overlay并返回相应的BMK3DModelOverlayView的实例
        BMK3DModelOverlayView *modelOverlayView = [[BMK3DModelOverlayView alloc] initWith3DModelOverlay:overlay];
        return modelOverlayView;
    }
    return nil;
}

3. 动画控制


/// 以下只支持带有animations标签的GLTF模型
/// 模型动画是否可用，默认为NO：添加后不执行动画，值为YES时添加后立即按照配置参数执行动画，since 6.5.7
@property (nonatomic, assign) BOOL animationIsEnable;
/// 模型动画重复执行次数，默认0：动画将一直执行动画，since 6.5.7
@property (nonatomic, assign) NSInteger animationRepeatCount;
/// 当前模型动画索引值，since 6.5.7
@property (nonatomic, assign) NSInteger animationIndex;
/// 模型动画倍速，默认：1.0，since 6.5.7
@property (nonatomic, assign) CGFloat animationSpeed;

Objective-C

Swift


BMK3DModelOption *option = [[BMK3DModelOption alloc] init];
option.scale = 2;
option.modelName = @"scenes";
option.type = BMK3DModelTypeGLTF;
option.zoomFixed = YES;
option.rotateX = 90;
option.animationIsEnable = YES;
option.animationIndex = 0;
option.animationSpeed = 1;
option.animationRepeatCount = 0;
option.modelPath = [NSString stringWithFormat:@"%@/Model3D", [NSBundle mainBundle].bundlePath];

4. 运行程序

效果如下:

绘制海量点

绘制动态轨迹
