Abstract: In one embodiment, a method retrieves mask information for creating a visual effect in a three-dimensional (3D) video. The mask information includes an outline of an object. The video is stored in a first buffer. The mask information is processed in a second buffer to create a mesh that extrudes from the outline of the object. The mesh includes values that describe a shading of the mesh and the mesh being formed around the outline of the object. The method then adjusts the values of the mesh in the second buffer to minimize discontinuities in gradients created in the mesh. When a time to display the visual effect is reached in the video, the method renders the mesh from the second buffer with video from the first buffer to form the visual effect around the object to indicate that an interaction with the object is available in the video.
