    i had a go at it. But, i’m a newbe, so i learned a few things, but im not assuming you can use it ;)

    First i made a box and a sphere. (For the screenshot i set the box transparant, and the view in ‘perspective’)

    Then did Part -> Split -> Boolean fragments

    Then did Part -> Compound -> Explode Compound

    And removed/hidden the excess parts:

    Next would be to fuse what’s left i guess

    But that last part, to flatten the tip with a circle which touches the 3 sides… i’m stuck

    "The romantacizing of native cultures is really prevalent but what people dont understand is that when they practice a native religion is that the territorial spirits that rule the US comes from First nations and that demonic bondage is pretty powerfull. But only through the blood of and the name of jesus christ anything can be broken and freed. Anyone can be freed. Nobody is too far gone. Once a person is saved, you see that light come back into their eyes. That’s a beutifull thing to see " 💎

    your sound is a 900Hz sine wave. i dont see your scope mentioning 900Hz anywhere. to represent a 900hz sinewave, you need about 4 samples at least, to represent a sine-ish-curve. i.e. 4 x900hz sampling rate. but also 4 pixels on screen to repseent the curve.

    But not looking at the numbers, an image like that could happen when the data which needs to be presented has more datapoints than the amount of pixels the display is wide (maybe your scope is 1024 pixels wide?) it could be the oscilloscope is just picking 1024 samples out of the millions of datapoints, and drawing lines between them(which will be vertical lines). That’s one way to get strange representations. What i see on the osccilliscope is countless vertical lines together making it look like a fill.

    To check if that’s it, you can zoom-in on the x-axis only, and check if the pattern changes(and eventually shows your sine wave)
