Patrick Walton	4e1a9a9bad	Add a new varying to the stencil AAA fragment shader for simplicity. The new `vXDist` values can be deduced simply from the `vUV` values and first-order derivatives thereof, and therefore they're technically redundant. However, calculating them in this way increases the complexity and ALU load in the fragment shader. It's simpler to just compute the additional values in the vertex shader and use interpolation.	2018-02-21 16:27:49 -08:00
Patrick Walton	a84b7c7cbd	Replace ECAA with "Stencil AAA", a distance-based antialiasing technique similar to the new MCAA. This new technique simplifies the code significantly by unifying lines, curves, and transformed curves. Blog posts forthcoming.	2018-02-17 10:45:25 -08:00

Add a new varying to the stencil AAA fragment shader for simplicity.

The new `vXDist` values *can* be deduced simply from the `vUV` values
and first-order derivatives thereof, and therefore they're technically
redundant. However, calculating them in this way increases the
complexity and ALU load in the fragment shader. It's simpler to just
compute the additional values in the vertex shader and use
interpolation.

technique similar to the new MCAA.
