Title: This Quad glow method looks nice
Post by: cheb on March 08, 2018, 03:40:24 AM

Seems like pure environment mapping + texture scroll but looks damn nice. :-*


I wonder if something similar could be implemented but with alpha testing instead of blending, so the glow shell is opaque in spots.
Also, the normals projected to uv could be also rotated and undulated, not just scrolled.  ::)

We've already got a quad shell similar to that.


Giving it an alphatest blend would make it slower actually.  3D hardware since 2002 perform an internal shader to accomplish that.  In addition, deformVertex normal is quite slow when applied to models.  Q3 only ever used them on flags to make the environment map glow move from the vertex waving. deformVertex normal's even slow with subdivided flat surfaces on maps so I can't really use them for water either (despite 3d games as far back as 1996 doing it with no sweat *cough*Wave Race 64*cough*)

Is there a screenshot available (or at least a specific time)?

That link should bring you at 9:17 (557 seconds, as specified in the link). At 9:18, the player activates Quad. :)

Hey thanks, it somehow didn't work the first time (perhaps a bad internet connection).
It looks nice, but nog that much of a difference towards the current one (except the scrolling part).
