3D cumulative scatter performance issues

Hi All,

I’m plotting a cumulative scatter animation using scatter3D and have encountered some issues with performance. The main one being that I’m rendering large amounts of data each frame. Notice when I declare my ‘frames’ there are moments where I’m re-rendering thousands of scatter dots every frame. Is there a way that I can store previous scatter data and only render one at a time? Instead of re-rendering them all? Is there support for a Scatter3dgl? Thanks!

#colorArr = build_color_arr()
micro_trace = go.Scatter3d(
    x=[],
    y=[],
    z=[],
    mode='markers',
    marker=dict(
        size=sData['RADIUS'] - (sData['RADIUS'] * .75),
        color=sData['RADIUS'],
        colorscale='rainbow'
    )
)

data = [micro_trace]

frames = [dict(data= [dict(type='scatter3d', # animations performance issue:
                           x=sData['LOC_X'][:k+1], ## rendering all scatter data every frame.
                           y=sData['LOC_Y'][:k+1],
                           z=sData['LOC_Z'][:k+1]*-1)],
               traces=[0],
