|
||
<p>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 <code>AtlasManager</code>, which when passed to the constructor
|
||
of a symbol style, will create atlases for the symbols.</p>
|
||
<p>See the <a href="symbol-atlas-webgl.js" target="_blank">symbol-atlas-webgl.js source</a> to see how this is done.</p>
