@Deltakosh BABYLON.RayHelper is not accessible in the playground: http://www.babylonjs-playground.com/#KNE0O#15

@getzel the demos playground in the tutorial no longer works (with ray.show() deprecated: see: https://github.com/BabylonJS/Babylon.js/blob/master/dist/preview release/what's new.md#breaking-changes)

error : http://doc.babylonjs.com/tutorials/raycasts

Ah, I do not use it well. But that's 3 more lines for use show (). I preferred as it was before, less complicated.

Why the change more complex. before, it was more direct. Now is really complicated.

I do not understand this change, which does not simplify.

The problem was more about memory. ray.show generated too much code and was not great for that. Now that we have an object to support it we can keep the ray small and efficient 

I'll update the tutorial. Thanks for the hint.

And let's be honest, it is not "Really complicated" :)

we move from:

ray.show(scene, new BABYLON.Color3(1, 1, 0.1));


var rayHelper = new BABYLON.RayHelper(ray);


I think it is a good trade off considering that now we can easily add more features to the helper without touching the pure math function for rays!
