In pdf java3d spec, on page 424 (Version 1.2, April 2000), you have nice
equation of this matrix, using m00, m01 etc. Unfortunately there is no
reference to "Real-Time Rendering", but I suppose that matrix layout for
multiplication, plus equations explaining how to compute matrix
multiplied by vector should be enough for comparison.
If you mean float[] constructor order, it is explained in long api -
"
Constructs and initializes a Matrix4f from the specified 16 element
array. this.m00 =v[0], this.m01=v[1], etc.
"
This time it is in most obvious place - Math Objects/Matrix Objects.
