Luna::lerp

Float4 lerp(const Float4 &v1, const Float4 &v2, f32 t)

Performs linear interpolation between two 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 + t * (v2.x - v1.x);
result.[y](struct_luna_1_1_float4_1ab7291adeb8828a0cba3aedf332c2053d.md) = v1.y + t * (v2.y - v1.y);
result.[z](struct_luna_1_1_float4_1aac280fcf3516d20b5e3dec5fa770ac50.md) = v1.z + t * (v2.z - v1.z);
result.[w](struct_luna_1_1_float4_1adb390a9d0e1ce3b726f016e547104e35.md) = v1.w + t * (v2.w - v1.w);
return result;

Parameters

• in v1

  The first vector.

• in v2

  The second vector.

• in t

  The interpolation weight.

Return value

Returns the interpolation result.
