"It's an old horseman tradition," a source tells PEOPLE of the gesture.
Held on the Sony Studios lot in Culver City, Calif., the service – attended by several hundred friends and family, including Whoopi Goldberg – incorporated many photos of Swayze riding his horses, along with a video tribute to the star, who died from pancreatic cancer on Sept. 14.
The memorial, planned by the actor's wife Lisa Niemi, featured speeches celebrating Swayze's life and a performance by professional dancers in honor of his talent.
"A whole dance floor was built," says another source. "The dancers did these amazing numbers."
In lieu of flowers, the family requested that donations be made to The Patrick Swayze Pancreas Cancer Research Fund or Stand Up to Cancer.
