cross

Cross product.

float4 cross ( float4 p0,
  float4 p1)

double4 cross (double4 p0, double4 p1) // if double extension enabled
half4 cross (half4 p0, half4 p1) // if half extension enabled

Description

Returns the cross product of p0.xyz and p1.xyz. The w component of float4 result returned will be 0.0.

Notes

Built-in geometric functions operate component-wise and the description is per-component.

The built-in geometric functions are implemented using the round to nearest even rounding mode.

The geometric functions can be implemented using contractions such as mad or fma.

If extended with cl_khr_fp64, generic type name gentype may indicate double and double{2|4|8|16} as arguments and return values. If extended with cl_khr_fp16, generic type name gentype may indicate half and half{2|4|8|16} as arguments and return values.
