How to create a neon material using SCNMaterial in swift?

I've been experimenting with SCNMaterials, focussing on emission to try and create a neon material. Not sure if it is possible, but if it could emit light, that would be great. Thanks :)

Solution

  • It's simple:

    material.emission.contents = [NSColor greenColor];

    all this does is make the material glow in it's own light.
    If you wish to make other objects affected by this neon light,
    you could add a light to your neon node like so:

    SCNLight *mylight = [SCNLight light];
mylight.type = SCNLightTypeOmni;
mylight.color = [NSColor greenColor];
myNeonNode.light = mylight;

    Hope that helped!

    Note:

    the power of the light can be controlled by the color you use:
    Dark green will seem like a green light that is not so powerful.
    Light green will seem like a green light that is more powerful.
