Luna::barycentric

Float4 barycentric(const Float4 &v1, const Float4 &v2, const Float4 &vec3, f32 f, f32 g)

Performs barycentric interpolation between three vectors.

This function performs the following operations:

[Float4](struct_luna_1_1_float4.md) result;
result.[x](struct_luna_1_1_float4_1a6b05cac69c0301ab972c27ce208373be.md) = v1.x + (v2.x - v1.x) * f + (v3.x - v1.x) * g;
result.[y](struct_luna_1_1_float4_1ab7291adeb8828a0cba3aedf332c2053d.md) = v1.y + (v2.y - v1.y) * f + (v3.y - v1.y) * g;
result.[z](struct_luna_1_1_float4_1aac280fcf3516d20b5e3dec5fa770ac50.md) = v1.z + (v2.z - v1.z) * f + (v3.z - v1.z) * g;
result.[w](struct_luna_1_1_float4_1adb390a9d0e1ce3b726f016e547104e35.md) = v1.w + (v2.w - v1.w) * f + (v3.w - v1.w) * g;
return result;

Parameters

  The first vector.

• in v2

  The second vector.

• in v3

  The third vector.

• in f

  The interpolation weight between v1 and v2.

• in g

  The interpolation weight between v1 and v3.

Return value

Returns the interpolation result.
