whether it's water or your gaming experience filtering can enhance it and
0:04
make it better we're going to be talking about bilinear trilinear and an
0:08
isotropic filtering options for improving texture appearance in games as
0:12
fast as possible many surfaces in games are covered in what are called textures
0:16
this is what avoids that effect where you just have like a flat surface with a
0:20
bunch of red squares on it being called a brick wall this is what makes them
0:24
actually look realistic but the problem with textures is that if you don't apply
0:28
any kind of filtering to them whatso ever you'll usually end up in a
0:31
situation where what's up close to the player character or the camera looks
0:35
great and what's a little ways off looks absolutely terrible and a sharply
0:39
defined line between great and terrible bilinear and trilinear filtering aim to
0:45
reduce the visibility of that line so when you're walking down a gravel path
0:49
or next to a brick wall with a repeating pattern it's not noticeable that oh hey
0:53
I'm in a game because I can tell right there it looks bad and right there it
0:57
looks good an isotropic filtering is more advanced than bilinear and
1:01
trilinear and seeks to reduce jaggies within the textures themselves or
1:05
aliasing and make them appear much higher quality especially when viewed at
1:10
extreme angles so in this example on the left it looks terrible past the
1:14
immediate vicinity of the plane that is presumably coming down on the runway
1:17
whereas on the right with an isotropic filtering enabled it looks great even
1:22
further on into the distance or at least much better compared to other visual
1:26
quality improvement techniques texture filtering is relatively non demanding on
1:30
your gaming hardware and many games these days even come with it enabled by
1:34
default so remember guys enable texture filtering on your games for the
1:39
best possible experience share this Techquickie like the video and as always
