WebDouble-precision matrices (GL 4.0 and above) can be declared with a dmat instead of mat (example: dmat4x4 ). OpenGL stores matrices in column-major format —that is, elements are stored contiguously in columns. Swizzling does not work with matrices. You can instead access a matrix's fields with array syntax: WebFirst, a point of clarification: row-major means something different than row vector. OpenGL uses column vectors, which abstractly means that you consider a vector as a 4x1 matrix, and transform a vector v by a matrix M with v' = M · v.
