is new shader accepts a second sampler and blends the blurred result of the rst
sampler to the second sampler to create the neon eect. e multiplier variable sets
how pronounced the neon eect will be.
e whole procedure renders twice to framebuers. e rst rendering is done in
a downsized viewport and only renders the spherical manifold. A Gaussian blur is
applied to the manifold. e second rendering renders both the globe and the surface
and both renderings are blended together with additive blending. e result is ren-
dered to the screen. Finally, we also render to the screen the globe and mesh ...
