--- layout: example.html title: Symbols with WebGL shortdesc: Using symbols in an atlas with WebGL. docs: >
When using symbol styles with WebGL, OpenLayers would render the symbol
on a temporary image and would create a WebGL texture for each image. For a
better performance, it is recommended to use atlas images (similar to
image sprites with CSS), so that the number of textures is reduced. OpenLayers
provides an AtlasManager, which when passed to the constructor
of a symbol style, will create atlases for the symbols.
