Constructor Details

#new ⇒ Vertex #new(position) ⇒ Vertex #new(position, color) ⇒ Vertex #new(position, color, tex_coords) ⇒ Vertex

Any omitted argument defaults to position (0, 0), color white, and tex_coords (0, 0).

Overloads:

  • #new ⇒ Vertex
  • #new(position) ⇒ Vertex
  • #new(position, color) ⇒ Vertex
  • #new(position, color, tex_coords) ⇒ Vertex
