VFPU functions

Functions
float	vfpu_sinf (float angle, float rayon)
float	vfpu_cosf (float angle, float rayon)

---

Detailed Description

Functions using the Vector Floating Point Unit (VFPU). Please note that the PC does not support the VFPU, using it results in extremely slow performance, and some of the calls may not be emulated properly, if at all.

Function Documentation

float vfpu_sinf	(	float	angle,
		float	rayon
	)

Calculates the sine of an angle using the VFPU (very fast). Please note that oslSin also uses the VFPU but first converts the angle from degrees to radians.

Parameters:

	angle	Angle in radians
	rayon	Radius

Returns:

sin(angle) * rayon

float vfpu_cosf	(	float	angle,
		float	rayon
	)

Calculates the cosine of an angle using the VFPU (very fast). Please note that oslCos also uses the VFPU but first converts the angle from degrees to radians.

Parameters:

	angle	Angle in radians
	rayon	Radius

Returns:

cos(angle) * rayon
