Function Documentation

ACos()

JPH_INLINE float ACos

(

float

inX

)

Arc cosine of x (returns value in the range [0, PI]) Note that all input values will be clamped to the range [-1, 1] and this function will not return NaNs like std::acos

ACosApproximate()

JPH_INLINE float ACosApproximate

(

float

inX

)

An approximation of ACos, max error is 4.2e-3 over the entire range [-1, 1], is approximately 2.5x faster than ACos.

ASin()

JPH_INLINE float ASin

(

float

inX

)

Arc sine of x (returns value in the range [-PI / 2, PI / 2]) Note that all input values will be clamped to the range [-1, 1] and this function will not return NaNs like std::asin

ATan()

JPH_INLINE float ATan

(

float

inX

)

Arc tangent of x (returns value in the range [-PI / 2, PI / 2])

ATan2()

JPH_INLINE float ATan2	(	float	inY,
		float	inX
	)

Arc tangent of y / x using the signs of the arguments to determine the correct quadrant (returns value in the range [-PI, PI])

Cos()

JPH_INLINE float Cos

(

float

inX

)

Cosine of x (input in radians)

Sin()

JPH_NAMESPACE_BEGIN JPH_INLINE float Sin

(

float

inX

)

Sine of x (input in radians)

Tan()

JPH_INLINE float Tan
