remove rendered object #72

Closed CarloLucibello closed 8 years ago

CarloLucibello commented 8 years ago

Since there is no example for this in the documentation, I'll ask here. How can I signal and implement the removal of one of the rendered object?

In my use case, for https://github.com/JuliaGraphs/GraphVisualize.jl, I'd like to signal the removal of an edge from a graph, therefore removing one of the segmente created by

lines  = visualize(gpu_position, :linesegment, indices=indices)

Can you point me to some way to do this? thanks

The easiest seems to be, if you just pass an index list to the points as well and then just remove indices. I updated the example! At some point it was possible to use splice! on the gpu array directly, but this currently introduces some complications.
