NettetActually, repeated addition of a matrix would be called scalar multiplication. For example, adding a matrix to itself 5 times would be the same as multiplying each element by 5. On the other hand, multiplying one matrix by another matrix is not the same as simply multiplying the corresponding elements. Check out the video on matrix multiplication. NettetIn mathematics, particularly in linear algebra, matrix multiplication is a binary operation that produces a matrix from two matrices. For matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix. The resulting matrix, known as the matrix product, has the number of rows of the ...
Nettet1. mar. 2014 · 5. glMultMatrix and associated functions are deprecated (and removed from core profiles) in more recent versions of OpenGL. Instead use a library such as GLM for tasks such as matrix multiplication (and much more). This is probably the way to go even if you want to continue using the fixed function pipeline (and a compatibility profile).
