I'm try to visualize in my head the concept of change of reference.
for that that i understand ,multiply a point for a matrix is equals to translate/rotate his orientation of axises.
And the axises orientation becomes the same for all points multiplied by the matrix , concatenate matrix multiplication is equal to increment the rotation/translation of axis, matrix by matrix.
may be?

thanks.

If you're asking whether that's correct, it might be, but I think the terminology used probably isn't clear or consistent enough to make a reasonable assessment.

If you're unsure about something in particular, perhaps you could provide an example or describe a specific case that you're wondering about.
