public function vkf_light_set(light, ambient, diffuse, specular, position) bind(C, name="vkf_light_set")

Arguments

Type IntentOptional Attributes Name
type(c_ptr), value :: light

light handle (vkf_light_create, vkf_viewer_light)
real(kind=c_float), intent(in), dimension(3) :: ambient

colors (rgb, 0 to 1)
real(kind=c_float), intent(in), dimension(3) :: diffuse

colors (rgb, 0 to 1)
real(kind=c_float), intent(in), dimension(3) :: specular

colors (rgb, 0 to 1)
real(kind=c_double), intent(in), dimension(4) :: position

OpenGL's (x, y, z, w): w = 0 for a directional light from direction (x, y, z), else a point light at (x/w, y/w, z/w)

Return Value integer(kind=c_int)

Description

Set a light's colors and position, in its node's coordinates. Returns 0 (-1 for a bad handle).
