##### How to properly clamp beckmann distribution

I am trying to implement a Microfacet BRDF shading model (similar to the Cook-Torrance model) and I am having some trouble with the Beckmann Distribution defined in this paper: https://www.cs.cornell.edu/~srm/publications/EGSR07-btdf.pdf Where M is a microfacet normal, N is the macrofacet normal and ab is a "hardness" parameter between [0, 1]. My issue is that this distribution often returns obscenely large values, especially when ab is very small. For instance, the Beckmann distribution is used to calculate the probability of generating a microfacet normal M per this equation : A probability

##### Limit integer to bounds [duplicate]

This question already has answers here: Most efficient/elegant way to clip a number? (10 answers) Closed 2 years ago. I'm trying to make sure that int x is greater or equal than 0 but smaller than 1080 (screen size in this case). I came up with this int x = 123; x = std::min(std::max(x, 0), 1080); This seems ugly. Is there a better way to achieve this?

##### Problems limiting object rotation with Mathf.Clamp()

I am working on a game that rotates an object on the z axis. I need to limit the total rotation to 80 degrees. I tried the following code, but it doesn't work. minAngle = -40.0f and maxAngle = 40.0f Vector3 pos = transform.position; pos.z = Mathf.Clamp(pos.z, minAngle, maxAngle); transform.position = pos;

##### Is there a method to limit/clamp a number?

I wrote the following code, which keeps x within the range (a..b). In pseudo code: (if x < a, x = a; if x > b, x = b) In Ruby it would be something like: x = [a, [x, b].min].max As it is quite basic and useful function, I was wondering if there is a native method to do that in ruby. As of Ruby 2.3.3 there is apparently no method like this, what would be the shortest/more readable way to do it? I found: x = [a, x, b].sort[1] so far, but I'm not sure if it is more readable.
