Method Down

Down(in float4x4)

Computes the "down" direction in a transformation matrix's reference frame.

Declaration

public static float3 Down(this in float4x4 m)

Parameters

Type	Name	Description
float4x4	m	A transformation matrix

Returns

Type	Description
float3	A vector pointing in the "down" direction of m's reference frame. By Unity's convention, this is negative Y axis. This vector does not necessarily have unit length.

Remarks

This method assumes that m is an affine transformation matrix without shear.
