Data processing method and apparatus, and electronic device and readable medium

An electronic device, comprising a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other through the communication bus;

• the memory is configured to store a computer program;
• and
• the processor, through executing the program stored in the memory, is configured to:
• obtain, in response to a touch control operation on a virtual model, a first grid position of the touch control operation in a model grid of the virtual model at a (n+1)-th timepoint, wherein n≥1;
• determine, based on the first grid position, a first texture position of a texture map of the virtual model;
• obtain information, in a render texture corresponding to the touch control operation at an n-th timepoint, of a color of a historical touch control region of the touch control operation, wherein the render texture is a texture generated based on a color of a historical position of the touch control operation in the texture map;
• obtain, a target color of the first texture position by mixing the color of the historical touch control region with a color of the first texture position;
• update the color of the first texture position of the texture map as the target color;
• and
• render, based on the texture map as updated, the virtual model at the (n+1)-th timepoint.

A non-transitory computer-readable medium, storing an instruction that, when executed by one or more processors, causes the processor to perform a data processing method, wherein the method comprises:

• obtaining, in response to a touch control operation on a virtual model, a first grid position of the touch control operation in a model grid of the virtual model at a (n+1)-th timepoint, wherein n≥1;
• determining, based on the first grid position, a first texture position of a texture map of the virtual model;
• obtaining information, in a render texture corresponding to the touch control operation at an n-th timepoint, of a color of a historical touch control region of the touch control operation, wherein the render texture is a texture generated based on a color of a historical position of the touch control operation in the texture map;
• obtaining, a target color of the first texture position by mixing the color of the historical touch control region with a color of the first texture position;
• updating the color of the first texture position of the texture map as the target color;
• and
• rendering, based on the texture map as updated, the virtual model at the (n+1)-th timepoint.
