WebApr 5, 2024 · Matrix storage in memory as a multidimensional array. In mathematics, a matrix is defined as a rectangular array of numbers arranged in rows and columns. For example, the matrix below has 3 rows and 5 columns, and can be referred to as a \mathbf {3 \times 5} 3×5 matrix. WebUsing vec3 seems ideal because it would theoretically save a lot of memory. But perhaps that temporary vec4 (position,1.0f); costs some runtime performance at the savings of memory.
