Wide corridor problem

[davidbourrel]

What happened?

Hi !

There's a problem with the corridor. With a width that's too wide, the corridor displays something it shouldn't. We need to display a fairly wide corridor in our project, but the displayed result is not correct.

I saw there's another post open since 2022 but nobody replied :/ Large and wide corridor wraps around

We can reproduce this bug on this sandcastle

Thank you

Hi @davidbourrel! Could you help us understand the use case for these wide corridors? I ask because it may help us understand if there is another route to achieve this. For instance, it's common for users to represent satellite swaths with polygons rather than corridors.

[davidbourrel]

Hi ! Thanks for your response !

We have several satellites and each satellite have his "swath" at the same time. This is what our application looks like with 2 satellites:

Code:

<Entity name={name}>
   <CorridorGraphics
        width={width}
        positions={positions.map((p) => new Cartesian3(p.x, p.y, p.z))}
        material={color.withAlpha(0.5)}
        height={1}
        cornerType={CornerType.BEVELED}
    />
</Entity>

width: are between 888093 and 941185

We want the same thing, except the little bug ^^. We have lots of points, so I may need to use data-decimation to make a corridor with polygons I think.

When to use corridor so ? I didn't understand that, I thought it was the perfect case to use it.

Thanks @davidbourrel!

We're already tracking this in #10654. I'm going to close your issue to keep the discussion in one place and move your comment there. If you have any further input on this, please post it there instead.
