Mix and Match Units

I find myself constantly annoyed by the seemingly random use of units in TG2. Degrees are used in some places (such a camera angles and sun position) while things such as "factors" are used elsewhere...such as the "lean factor" in Twist & Shear. Why, in the latter instance, is 1 equal to 45 degrees? That scarcely seems intuitive...especially if one is after a specific angle. (Quick, everyone, what angle is a lean factor of 1.27 equal to? What lean factor is equivalent to 16 degrees? If it took you longer than 5 seconds to answer either then I rest my case...) I find this sort of thing throughout TG2...



I guess the developers will work on simplifying the tweaks and sliders for future versions. This is a technology preview, you have to remember.


Re. Lean factor, I imagine that the lean factor is the tangent of the angle as you've been using it. tan(45) = 1; I had to do [Win]-[R] calc [Enter] to find the other ones, but the angle corresponding to a lean factor of 1.27 would be about 51 degrees, and the lean factor corresponding to 16 degrees would be about 0.287. That takes about 5 seconds each, if you know how to do it. I'm a math major, so perhaps I have an unfair advantage--but 45 degrees mapping to 1 just screams "TANGENT!" to me.

It makes sense, really: a lean factor of 1 tilts a vertical face over as far as it is tall; a lean factor of 2 tilts it over twice as far; etc. Planetside could include a built in converter, but it's really not hard to figure it out yourself.


To those math major flunkees (raising my hand), it isn't intuitive.

So this is Disney World.  Can we live here?
