To get Regegigas you need Regirock, Regice and Registeel. To get them you need to find them in Pokemon Ruby or Sapphire then migrate them to Platinum and put them in your party and go down the temple in Snowpoint City to the basement and Regigas should be there. Hope this helps.
First have all three regis in your party and go to the last floor at Snowpoint Temple, on the fifth floor of the basement.
