Convert your quaternion to a rotation matrix, and use it in the Model Matrix. WebA mathematical matrix is defined as m x n matrix. Where m is a number of rows and n is number of columns. For the sake of completeness, rows are horizontals, columns are vertical. When denoting a matrix element in mathematical notation Mij, the first element ( i) is a row index, the second one ( j) is a column index.
