Transform4D::SetScale

Defined in: C4Matrix4D.h

Sets a matrix to represent a scale.

Prototype

Transform4D& SetScale(float t);

Transform4D& SetScale(float r, float s, float t);

Parameters

`s`	The scale along the x axis.
`r`	The scale along the y axis.
`t`	The scale along the z axis, or if specified by itself, the scale along all three axes.

Description

The SetScale function replaces all entries of a matrix with those representing a scale. If only the t parameter is specified, then the scale is uniform along all three axes. If the r, s, and t parameters are specified, then they correspond to the scale along the x-, y, and z axis, respectively. The entries of the fourth row and fourth column of the matrix are set to those of the identity matrix.

The return value is a reference to the matrix object.
