20 Setting Up Transformation Matrices
Q3Matrix3x3_SetScale
function to configure a 3-by-3 scaling transformation matrix.
TQ3Matrix3x3 *Q3Matrix3x3_SetScale ( TQ3Matrix3x3 *matrix3x3, float xScale, float yScale);matrix3x3
A 3-by-3 matrix.xScale
The desired amount of scaling along the x coordinate axis.yScale
The desired amount of scaling along the y coordinate axis.
Q3Matrix3x3_SetScale
function returns, as its function result and in the matrix3x3
parameter, a scaling matrix that scales an object by the amount xScale
along the x coordinate axis and by the amount yScale
along the y coordinate axis.
