VEC4_LEN

Evaluates to the number of components of a #graphene_vec4_t.

This symbol is useful when declaring a C array of floating point values to be used with graphene_vec4_init_from_float() and graphene_vec4_to_float(), e.g.

|[ float vGRAPHENE_VEC4_LEN;

// vec is defined elsewhere graphene_vec4_to_float (&vec, v);

for (int i = 0; i < GRAPHENE_VEC4_LEN; i++) fprintf (stdout, "component %d: %g\n", i, vi); ]|
