3D paint effects in a messaging system

A computing device comprising:

• a memory that stores instructions;
• and
• one or more processors configured by the instructions to perform operations comprising:
• determining a location of a selection in a space viewable in a camera view on a display of the computing device;
• detecting movement of the computing device;
• generating a path starting from the location of the selection and following the movement of the computing device by performing operations comprising:
• generating a three-dimensional (3D) mesh along the path following the movement of the computing device using multiple X, Y, and Z coordinates calculated based on the movement of the computing device;
• populating the 3D mesh with a selected color and texture type to generate a first 3D paint object;
• and
• causing the generated first 3D paint object to be displayed;
• receiving data for a second 3D paint object being drawn on a second computing device in the space;
• causing display of the second 3D paint object being drawn on the second computing device during display of the first 3D paint object;
• receiving a request to send a message comprising an image or video overlaid by the first 3D paint object;
• capturing the image or video overlaid by the displayed first 3D paint object;
• generating the message comprising the image or video overlaid by the first 3D paint object;
• and
• sending the message to a third computing device.

A non-transitory computer-readable medium comprising instructions stored thereon that are executable by at least one processor to cause a computing device to perform operations comprising:

• determining a location of a selection in a space viewable in a camera view on a display of the computing device;
• detecting movement of the computing device;
• generating a path starting from the location of the selection and following the movement of the computing device by performing operations comprising:
• generating a three-dimensional (3D) mesh along the path following the movement of the computing device using multiple X, Y, and Z coordinates calculated based on the movement of the computing device;
• populating the 3D mesh with a selected color and texture type to generate a first 3D paint object;
• and
• causing the generated first 3D paint object to be displayed;
• receiving data for a second 3D paint object being drawn on a second computing device in the space;
• causing display of the second 3D paint object being drawn on the second computing device during display of the first 3D paint object;
• receiving a request to send a message comprising an image or video overlaid by the first 3D paint object;
• capturing the image or video overlaid by the displayed first 3D paint object;
• generating the message comprising the image or video overlaid by the first 3D paint object;
• and
• sending the message to a third computing device.
