PI_2

VEC2_LEN

static final int VEC2_LEN

Evaluates to the number of components of a #graphene_vec2_t.

This symbol is useful when declaring a C array of floating
point values to be used with graphene_vec2_init_from_float() and
graphene_vec2_to_float(), e.g.

   float v[GRAPHENE_VEC2_LEN];
 
   // vec is defined elsewhere
   graphene_vec2_to_float (&vec, v);
 
   for (int i = 0; i < GRAPHENE_VEC2_LEN; i++)
     fprintf (stdout, "component %d: %g\n", i, v[i]);

VEC3_LEN

static final int VEC3_LEN

Evaluates to the number of components of a #graphene_vec3_t.

This symbol is useful when declaring a C array of floating
point values to be used with graphene_vec3_init_from_float() and
graphene_vec3_to_float(), e.g.

   float v[GRAPHENE_VEC3_LEN];
 
   // vec is defined elsewhere
   graphene_vec3_to_float (&vec, v);
 
   for (int i = 0; i < GRAPHENE_VEC2_LEN; i++)
     fprintf (stdout, "component %d: %g\n", i, v[i]);

VEC4_LEN

static final int 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 v[GRAPHENE_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, v[i]);
