I am creating a Matrix that will be used as the matrix for my particles.
I have a few questions about Matrices.
When I Create a matrix like...
I would like to know the following...
is... m.off = the center position of the matrix. Where it is centrally located in global space?
also... when I define the axis vector (i.e m.v1, m.v2, and m.v3) am I defining the position in global space that the tip of the axis is pointing toward?
If this is true, by defining a matrix like this.
m.off = Vector(0, 0, 0);
m.v1 = Vector(100, 0, 0);
m.v2 = Vector(0, 100, 0);
m.v3 = Vector(0, 0, 100);
I am creating a matrix that sits at world center with axis that extend outward a perfect center for x, y, and z 100.. Right?
Hopefully these questions make sense. My ultimate goal is to create a matrix for my particles so that they can be moved, rotated, and scaled with the matrix.
Is my understanding of creating a matrix correct?
PS If I am noit correct, could someone explain to me what the v1, v2, and v3 represent.

the length of v1,v2 and v3 also defines the scale of the object. Check the C++ AND coffee documentation, it´s explained in there. Otherwise take a look at matrix operations in general in every math book for further information.
