EEVEE Edge detect effect I am trying to replicate an effect that one of my friends made and he was able to detect the edges of an object using Eevee all using nodes no wireframe modifiers or anything but the only way I can get close to being able to do this is with cycles. Video here.
As cubes (head), or scaled cubes (arms, notice the variations of the edge thickness for arms), you can compare the location to some threshold.
Edge detection: top line in the image below
We can take generated coordinates, and recenter them to -0.5/+0.5,
Get absolute of that.
Compare each coordinate to a threshold.
And detect the edge if more than two dimensions are above this threshold.
Camera facing effect: bottom line below
Compare the incoming vector to the normal using a dot product.
Keep only what is above a threshold.
Combine with the edge detection.
