Deformed and irregular dots on vector line.

[sk1me]

TANGRAM VERSION:

15.2

ENVIRONMENT:

Windows 10, Chrome

TO REPRODUCE THE ISSUE, FOLLOW THESE STEPS:

Use shader for tangram: http://tangrams.github.io/blocks/#lines-dots

RESULT:

Dots on vector line are irregular, deformed and sharp.

There is also problem with using dashed lines - irregular chunks of lines.

EXPECTED RESULT:

Beautiful, smooth and placed within regular space dots.

@sk1me That's an old example with raw shader code.

Try the newer implementation as documented here:

Note that the dash parameter is for dashes only – there's no equivalent "dots" line style. For dots you'll still need a custom shader. For smooth dots you'll need a shader with antialiasing built in, but spacing will still be an issue, as UV coordinates are not consistent between features or across tiles.

@sk1me Just saw your reaction emoji 😅 If you let me know which parts of this are confusing I can try to shed some more light on the issue for you… Regardless, as this seems to be an issue with this particular shader and not the library, I'll close it.
