BumpMap* Renderable::m_bumpmap [protected] |
Bump map associated with primitive. May be null. Bump maps are associated with the primitive and not the material as they affect the "structure" of the object as opposed to simply the coloring and shading of the object.
Definition at line 113 of file renderable.h.
Referenced by get_final_normal(), initialize(), Plane::Plane(), and Polygon::Polygon().
Point3D Renderable::m_center [protected] |
"Center" of object. Some objects do not have a true center, such as a plane, but to simplify the lighting algorithm we need to move this to Renderable. This might also be useful in the future for centering textures or materials around.
Definition at line 106 of file renderable.h.
Referenced by Sphere::collides_with(), get_center(), get_diffuse(), Sphere::get_normal(), get_opacity(), get_reflection(), get_reflectivity(), get_refraction_index(), is_light(), and Sphere::Sphere().
bool Renderable::m_center_material [protected] |
Material centering policy. When set to true, materials will be centered to the center of the primitive.
Definition at line 118 of file renderable.h.
Referenced by get_diffuse(), get_opacity(), get_reflection(), get_reflectivity(), get_refraction_index(), get_specular(), initialize(), and is_light().
Material* Renderable::m_material [protected] |
Material of the object. Materials may be simple materials, such as a solid color, or they may be complicated composites, such as checkered marble, but one primitive only considers itself to have one material.
