Stretched Heatmap point

[Kserksis]

Helle Christopher,
when I imported you project and did a touch event I received a stand result (see picture).
You have an idea why I got this? I think the problem is in the pixel data array but I'm not sure.
Best regards

Hi, I think is the maximum number of color render by GPU. In some places I see the number 4 to render a color per pixel, maybe the code isn't was updated.

Understanding Color-Renderable Pixel Format Sizes

I will make a PR if found a fix.

As a temporal solution, in the TouchHeatmapRenderer class, you can change let touchradius : CGFloat = 70.0 value to something like 20.0, 40.0, 80.0, etc. and it will render the touch correctly.
I'm researching why this happens.

Greetings!

I haven't worked on this (or iOS) for quite a while now, If anyone opens a PRs I'd be more than happy.
