Can someone please explain to mean why the angle of isometrix is 25.565 instead of 30. Because by my logic the sin of a 2x1 triangle (sin(1/2)) is 30. And I don't see why it should be 25.565 even though it is.

An traditional Isometric view is based on an angle of 30 degrees, however due to the nature of Computer Monitors 30 degrees gives a messy and uneven line when displayed on a screen. Pixelart uses an angle of roughly 25.565 degrees. Don't worry about the sudden appearance of mathematics you don't really need to concern yourself with all these numbers.
:-p that's where i got the number from. ut I wanna knowwhy it looks like that, because by the current (obviously incorrect) math it shouldn't.
In the fields of video games and pixel art, the isometric projection used may deviate slightly due to the limitations of raster graphics; without anti-aliasing, lines in the x and y axes would not follow a neat pattern when drawn 30?? to the horizontal, and earlier computer graphics were also less capable of supporting more colors to effectively utilize anti-aliasing. Typically, a 2:1 pixel pattern ratio is used to simulate x and y axes lines, resulting in these axes following a 26.565?? (arctan 0.5) angle to the horizontal instead
...I just realised that..I was taking 2 as the hypotenuse, which just doesn't work.Grrr. Ah well.
