Method and apparatus for detecting picked object, computer device, readable storage medium, and computer program product

A computer device, comprising a memory and one or more processors, the memory storing computer-readable instructions, and the computer-readable instructions, when executed by the one or more processors, causing the computer device to perform a method for detecting a picked object including:

• detecting trigger location information of a trigger operation when a display interface displays a first image frame, the first image frame being any image frame in an updating process of the display interface being at a preset frequency;
• in a process of rendering a second image frame by using a graphics processing unit, obtaining location information of a pixel associated with each three-dimensional model in the second image frame, and matching the location information of the pixel associated with each three-dimensional model with the trigger location information, the second image frame being an Nth image frame after the first image frame, and N being a positive integer;
• storing, by using the graphics processing unit, a model identifier of a three-dimensional model associated with a pixel with location information successfully matched with the trigger location information, to a storage location in a color buffer that corresponds to the successfully matched pixel;
• and
• obtaining the model identifier in the color buffer by using a central processing unit, and determining, based on the obtained model identifier, the picked object specified by the trigger operation.

One or more non-transitory readable storage media, storing computer-readable instructions, the computer-readable instructions, when executed by one or more processors of a computer device, causing the computer device to implement a method for detecting a picked object including:

• detecting trigger location information of a trigger operation when a display interface displays a first image frame, the first image frame being any image frame in an updating process of the display interface being at a preset frequency;
