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: Web5 de jun. de 2012 · The difference in “row major” and “column major” is only in what order the numbers are stored in memory.
