Q3Matrix4x4_SetTranslate

You can use the Q3Matrix4x4_SetTranslate function to configure a 4-by-4 translation transformation matrix.

TQ3Matrix4x4 *Q3Matrix4x4_SetTranslate (
TQ3Matrix4x4 *matrix4x4, 
float xTrans, 
float yTrans, 
float zTrans);

matrix4x4

A 4-by-4 matrix.

xTrans

The desired amount of translation along the x coordinate axis.

yTrans

The desired amount of translation along the y coordinate axis.

zTrans

The desired amount of translation along the z coordinate axis.

DESCRIPTION

The Q3Matrix4x4_SetTranslate function returns, as its function result and in the matrix4x4 parameter, a transformation matrix that translates an object by the amount xTrans along the x coordinate axis, by the amount yTrans along the y coordinate axis, and by the amount zTrans along the z coordinate axis.
