And S402, if yes, determining a proxy model corresponding to the local model.

If the second screen duty ratio is smaller than or equal to the second preset screen duty ratio, that is, the second screen duty ratio meets the preset condition, it is indicated that the second bounding box is far away from the virtual camera, so that the proxy model corresponding to the local model, that is, the rough model corresponding to the local model, can be determined.

If the second screen duty ratio is greater than the second preset screen duty ratio, that is, the second screen duty ratio does not meet the preset condition, it is indicated that the second bounding box is closer to the virtual camera, and therefore, a proxy model of the second model and/or model information corresponding to the second model included in the local model corresponding to the second bounding box need to be further determined.

For example, the number of the local models may be 4, and the second enclosure box corresponding to each local model includes: A. b, C, D; and if the second screen ratio of the second surrounding boxes A and C is smaller than or equal to the second preset screen ratio, determining the proxy models of the two local models corresponding to the second surrounding boxes A and C, and if the second screen ratio of the second surrounding boxes B and D is larger than the second preset screen ratio, determining the proxy models corresponding to the two local models corresponding to the second surrounding boxes B and D and/or model information corresponding to the second models included in the two local models.

Optionally, fig. 6 is a flowchart of a model loading method in a game provided by the embodiment of the present invention, as shown in fig. 6, in S403, determining, according to a size of a second model included in each local model and a second preset screen ratio, a proxy model corresponding to each local model and/or model information corresponding to the second model included in each local model, including:

s501, calculating a third screen duty ratio of a third bounding box corresponding to the second model included in each local model according to the size, the second distance and the view angle of the virtual camera of the second model included in each local model.

Wherein the view angle of the virtual camera is preset. The third bounding box is used to frame the second model.

In some implementations, the screen height is calculated based on the second distance and the view angle of the virtual camera; determining each local model corresponding to a second surrounding box with the second screen duty ratio larger than the second preset screen duty ratio; a third screen ratio of a third bounding box is calculated based on the size of the second model included within the partial models and the screen height.

If the second screen duty ratio is larger than the second preset screen duty ratio, and the second model does not exist in the local model corresponding to the second surrounding box, model information of the local model is directly determined.

For example, the second screen ratio of the second bounding boxes a and C is smaller than or equal to the second preset screen ratio, the second screen ratio of the second bounding boxes B and D is larger than the second preset screen ratio, and the third screen ratio of the third bounding box corresponding to the second model included in the local model B is calculated according to the size of the second model included in the second bounding box B, the second distance between the second bounding box B and the virtual camera, and the view angle of the virtual camera. Similarly, a third screen duty ratio of a third bounding box corresponding to the second model included in the local model D is calculated according to the size of the second model included in the second bounding box D, the second distance between the second bounding box D and the virtual camera and the view angle of the virtual camera.

It should be noted that, if the third screen duty ratio is less than or equal to the second preset screen duty ratio, it is explained that the second model framed by the third bounding box corresponding to the third screen duty ratio is far from the virtual camera, so that the proxy model of the second model can be obtained and used as the proxy model of the local model.

S503, taking model information corresponding to a second model with a third screen duty ratio larger than a second preset screen duty ratio as model information corresponding to the second model included in each local model.

In this embodiment of the present application, if the third screen duty ratio is greater than the second preset screen duty ratio, it is indicated that the distance between the second model framed by the third bounding box corresponding to the third screen duty ratio and the virtual camera is relatively close, so that model information of the second model may be obtained and used as model information corresponding to the second model included in the local model.

For example, the second bounding box B includes three second models, and third bounding boxes corresponding to the three second models are respectively: a1, B1 and c1, determining model information of a second model corresponding to the third bounding box a1 and B1 when the third screen ratio of the third bounding box a1 and B1 is larger than the second preset screen ratio, and determining a proxy model corresponding to the third bounding box c1 as a proxy model of the second bounding box B when the third screen ratio of the third bounding box c1 is smaller than or equal to the second preset screen ratio.

The second bounding box D comprises two second models, and third bounding boxes corresponding to the two second models are respectively: a2, b2, determining model information of a second model corresponding to the third bounding box a2 when the third screen ratio of the third bounding box a2 is larger than the second preset screen ratio, and determining a proxy model corresponding to the third bounding box b2 as a proxy model of the second bounding box D when the third screen ratio of the third bounding box b2 is smaller than or equal to the second preset screen ratio.

In the related art, a preset distance is configured, the preset distance is 50 meters, a model is displayed as a fine model within 50 meters, and the model is directly cut out from the 50 meters. This can lead to a strange phenomenon: the combined model may be determined to be displayed at a distance from the box, the combined model including the box. That is, the user will see the box. When the user moves a little distance to the box and just reaches the condition that the original model needs to be switched, if the distance between the camera and the box is larger than 50, the box is cut off again, and the problem of unreasonable display exists in the related technology.

Aiming at the technical problems in the related art, according to the size, the second distance and the view angle of the virtual camera of the second model included in each local model, the third screen occupation ratio of the third bounding box corresponding to the second model included in each local model is calculated, so that the model can be prevented from jumping, and the display is more reasonable.

S602, if yes, determining that a proxy model of the local model corresponding to the second screen occupation ratio and model information of the second model in the local model corresponding to the second screen occupation ratio do not participate in rendering.

In this embodiment of the present application, if the second screen duty ratio is less than or equal to the third preset screen duty ratio, it is indicated that the local model framed by the second bounding box corresponding to the second screen duty ratio is far away from the virtual camera, and the local model is not required to be displayed, so that the proxy model of the local model and the model information of the second model in the local model do not participate in rendering.
