Map vs Map-less Apps

Rendering mode

• Static - Tiled Layer, Dynamic Map Service Layer, Feature Layer, Graphics Layer/Overlay (option)- Textures are rendered on GPU

• Dynamic - Graphics Layer/Overlay (option), Labels, GPS Layer- Symbols are converted to textures- Geometries are converted to triangles and texturized at render time

Static Rendering Mode For Graphics

• Rendering primarily done through CPU• Designed for cartographic quality

- Whole graphic is rendered as a path

• Scales up well

• Can be system memory intensive• Can drain your battery• Updates to graphic require a redraws of the image• View changes require full or partial updated to image

System Memory GPUMemory

Dynamic Rendering Mode For Graphics

• Entire graphic representation lives on the GPU• Some graphic changes can be applied directly to the GPU state

- For example moving or animating

• Number and complexity of graphics can impact GPU resources• Symbology could look a little different• Performance is the priority

Static vs Dynamic Rendering Mode Summary

• Static Mode - Designed for cartographic quality- Only regenerate textures when we need to - Increasing or decreasing the number of graphics within a layer does not affect number of

textures on the GPU

• Dynamic Mode- Entire graphic representation lives on the GPU

- No CPU update required when panning, zooming, or rotating the map- Some graphic changes can be applied directly to the GPU state- Graphics can remain screen aligned while map is rotating
