Aurora Borealis Shader

[mark]

Dear All,

A user asked on the Isadora User Group if Isadora could produce the Aurora Borealis. Here's an adaptation of a ShaderToy shader that does a pretty good job.

The LOAD is reasonable up to 1280x720, but at 1920x1080 it skyrockets to above 100% because of this line in the code:

for(float i=0.;i<50.;i++) {

// inside of loop

}

If you really want 1920x1080, change the number 50 in the code above to 25.

Beset Wishes,
Mark
