SceneViewPerformanceInfo

require(["esri/views/3d/support/SceneViewPerformanceInfo"], function(SceneViewPerformanceInfo) { /* code goes here */ });
Object: esri/views/3d/support/SceneViewPerformanceInfo
Since: ArcGIS API for JavaScript 4.15

This class contains information about performance in the scene like global memory usage and additional details for layers about memory consumption and number of features.

This class is experimental and should be used for debugging purposes only. Its interface will change in future releases.

Property Overview

Property Details

edgesMemory Number

An estimate of the memory used by the Edges3D feature when added to 3D objects in SceneLayer or to polygons with ExtrudeSymbol3DLayer symbols.

layerPerformanceInfos LayerPerformanceInfo[]

An array representing detailed information about memory usage of most layers.

quality Number

Quality level as a number between 0 and 1. The quality decreases when layers would need more memory than available, which reduces the level of detail, number of features and tile resolution.

terrainMemory Number

An estimate of the memory currently in use by ElevationLayer and tiled layers, in bytes.

This property also includes internal memory of the terrain subsystem, e.g., memory used to composite tiles in case multiple tiled layers are added to the scene.

totalMemory Number

The total memory available to the SceneView, in bytes.

usedMemory Number

An estimate of the memory that is in use by the SceneView, in bytes.
