Strange behaviour at zoom=0.5

[rsbyrne]

Hi there,

Take the below snippet with zoom(0.5000001) and compare it to what you get with zoom(0.50000001).

Seems to be some special behaviour going on as you approach zoom 0.5. Might be worth a look?

-R

import lavavu

data = whatever

lv = lavavu.Viewer()
lv["background"] = "black" #Set the plot background colour
lv["axis"] = False
lv["border"] = False
points = lv.points(pointsize=5, pointtype="shiny", opacity=1.)
cmap = points.colourmap(lavavu.cubehelix(samples=32, rot=3)[4:-4]) #, range=[0,0.1])
points.vertices(data)
points.values(range(len(data.T)))

def displaydata():
    lv.reload()
    lv.display(resolution=(600,600))

lv.fov(90)
lv.zoom(0.5000001)

displaydata()

Thanks for the report Rohan, I'm still trying to work this one out, it's really strange.

Aha, found it, damn edge cases
