Function Documentation

genType glm::core::function::trigonometric::acos ( genType const &  x  ) 

Arc cosine.

Returns an angle whose sine is x. The range of values returned by this function is [0, PI]. Results are undefined if |x| > 1. (From GLSL 1.30.08 specification, section 8.1)

genType glm::core::function::trigonometric::acosh ( genType const &  x  ) 

Arc hyperbolic cosine; returns the non-negative inverse of cosh.

Results are undefined if x < 1. (From GLSL 1.30.08 specification, section 8.1)

genType glm::core::function::trigonometric::asin ( genType const &  x  ) 

Arc sine.

Returns an angle whose sine is x. The range of values returned by this function is [-PI/2, PI/2]. Results are undefined if |x| > 1. (From GLSL 1.30.08 specification, section 8.1)

genType glm::core::function::trigonometric::asinh ( genType const &  x  ) 

Arc hyperbolic sine; returns the inverse of sinh.

(From GLSL 1.30.08 specification, section 8.1)

genType glm::core::function::trigonometric::atan ( genType const &  y_over_x  ) 

Arc tangent.

Returns an angle whose tangent is y_over_x. The range of values returned by this function is [-PI/2, PI/2]. (From GLSL 1.30.08 specification, section 8.1)

genType glm::core::function::trigonometric::atan ( genType const &  y,
genType const &  x 
)

Arc tangent.

Returns an angle whose tangent is y/x. The signs of x and y are used to determine what quadrant the angle is in. The range of values returned by this function is [-PI, PI]. Results are undefined if x and y are both 0. (From GLSL 1.30.08 specification, section 8.1)
