checkMaterialTypes()

MATERIAL_TYPES MaterialUtils::checkMaterialTypes

(

const std::vector< const Material * > &

materials

)

Checks if all non-default materials in materials are of the same type and returns this type.

If several types of materials are involved, InvalidMaterialType identifier is returned.

    MATERIAL_TYPES result = MATERIAL_TYPES::RefractiveMaterial;

        if (isDefault) {
