[OpenLayers-Users] Feature layer: toggle feature visibility

[Nils B. Weidmann]

Hi there,

I am developing an animation of spatio-temporal data. Is there a way to 
toggle feature visibility in a Vector layer efficiently? At the moment I 
set the opacity style attribute for the features to be shown/hidden, and 
redraw() the layer. However, this procedure is very slow. Is there a way 
to make it faster?

Thanks!
Nils
