The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0068] See also Figure 1 , which shows the balloon model deformation simulation method provided by the first embodiment of the present invention. The balloon model deformation simulation method provided by this embodiment can accurately simulate the physical interaction between the user and the virtual balloon in the virtual reality environment, thereby correspondingly improving the user experience.

[0069] Specifically, this embodiment provides:

[0070] A balloon model deformation simulation method specifically comprises the following steps:

[0071] Step S10, creating a balloon model in real time in the Unity scene, and adding a corresponding first simulation component to the balloon model;

[0072] Step S20, creating a hand model corresponding to the VR handle in real time in the Unity scene, and adding a corresponding second simulation component to the hand model;

[0073] Step S30, when it is detected in real time that the balloon model collides with the hand model, physical parameters corresponding to the collision are collected in real time based on the first simulation component and the second simulation component, and a local deformation degree corresponding to the balloon model is calculated in real time based on the physical parameters;

[0074] Step S40, calculating the restoring force corresponding to the balloon model in real time according to the degree of the local deformation, and completing the elastic restoration of the balloon model according to the magnitude of the restoring force.

[0075] Specifically, in this embodiment, it should be noted that in order to truly simulate the interactive experience between the user and the virtual balloon, it is necessary to accurately obtain the corresponding information generated when the user collides with the virtual balloon and perform corresponding analysis and processing. Based on this, the present invention will first create the required balloon model in the virtual reality scene through the existing Unity (creation platform) engine. Similarly, a hand model corresponding to the VR handle used by the user will also be created. At the same time, corresponding collision and physical properties will be added respectively, that is, corresponding collision components and physical property components will be added respectively to support corresponding physical interactions.

[0076] Furthermore, in the actual simulation process, when the server set in the background detects in real time that the balloon model collides with the hand model, the present invention can collect the physical parameters corresponding to the current collision in real time based on the first simulation component and the second simulation component. Based on this, the local deformation degree corresponding to the surface of the current balloon model, that is, the collision degree of the current balloon model, can be objectively calculated according to the current physical parameters. On this basis, the interaction scene corresponding to the collision between the user and the balloon can be simulated. Correspondingly, after the collision between the user and the balloon model is completed, in order to complete the recovery of the balloon model, it is necessary to further calculate the specific restoring force required by the current balloon model in the recovery process according to the current local deformation degree in real time. Based on this, the elastic recovery of the current balloon model is completed in real time according to the magnitude of the current restoring force, so that the recovery scene of the balloon model can be simulated, so that the physical interaction between the user and the balloon model can be accurately simulated, and the user's experience is improved accordingly.

[0077] Second embodiment

[0078] Furthermore, the step of collecting corresponding physical parameters generated during the collision in real time based on the first simulation component and the second simulation component includes:

[0079] Acquire mesh vertex data corresponding to the balloon model in real time according to the first simulation component and the second simulation component;

[0080] When it is detected in real time that the balloon model collides with the hand model, a corresponding target ray is emitted toward the balloon model in a direction from the hand model to the balloon model, and the physical parameters are correspondingly collected according to the target ray.

[0081] Furthermore, the step of collecting the physical parameters according to the target ray includes:

[0082] According to the target ray, a collision point corresponding to the hand model is detected in real time on the surface of the balloon model;

[0083] The normal direction corresponding to the target ray is detected in real time at the collision point, and the deformation force corresponding to the hand model is detected in real time at the collision point according to the normal direction, so as to obtain the physical parameters accordingly.

[0084] Furthermore, the step of calculating in real time the degree of local deformation corresponding to the balloon model according to the physical parameters includes:

[0085] When mesh vertex data corresponding to the balloon model is acquired in real time, a plurality of mesh vertices corresponding to the balloon model are detected in real time from the mesh vertex data;

[0086] The target vector between the collision point and the mesh vertex is calculated in real time according to the normal direction and the deformation force, and the vertex velocity corresponding to the mesh vertex is calculated in real time according to the target vector, so as to calculate the local deformation degree according to the vertex velocity.

[0087] Furthermore, the step of calculating the local deformation degree according to the vertex velocity includes:

[0088] When the vertex velocity is acquired in real time, the deformation time corresponding to the balloon model is detected in real time;

[0089] The local deformation degree corresponding to the balloon model is calculated according to the vertex velocity and the deformation time.

[0090] Furthermore, the step of calculating the restoring force corresponding to the balloon model in real time according to the local deformation degree includes:

[0091] When the target vectors corresponding to each of the collision points are acquired in real time, the initial position and the changed position corresponding to the target vectors are detected in real time;

[0092] Calculating in real time a target offset between the initial position and the changed position, and determining in real time an elastic coefficient corresponding to the collision point according to the target offset;

[0093] The restoring force is calculated according to the target offset and the elastic coefficient, and the restoring force includes a specific value.

[0094] Furthermore, the step of completing the elastic recovery of the balloon model according to the magnitude of the recovery force includes:

[0095] Calculating a restoring force vector corresponding to the collision point in real time according to the restoring force, and updating the vertex velocity by using the restoring force vector to generate a corresponding restoring velocity;

[0096] The elastic recovery of the balloon model is completed according to the recovery speed and the recovery force.

[0097] In addition, in the present embodiment, it should be noted that after the required balloon model and hand model are respectively obtained through the above steps, the corresponding simulation can be performed at this time. Preferably, the present invention will touch the current hand model to the current balloon model to simulate the user's interactive operation. Specifically, when it is detected that the hand model touches the balloon model, a target ray will be immediately emitted according to the position touched by the current hand model. Preferably, the target ray can detect the normal direction corresponding to the surface of the collision point between the current hand model and the current balloon model, and then apply a deformation force to the current balloon model according to the current normal direction, and further calculate the direction and distance of the force generated when the two collide in real time according to the current deformation force.

[0098] Furthermore, it should be pointed out that in the field of virtual reality, the three-dimensional models created are composed of a series of mesh vertex data, that is, they are composed of a series of meshes and corresponding vertices. Based on this, the present invention will detect the corresponding mesh vertices contained in the current balloon model, and in the process of the hand model colliding with the balloon model, the target vector between the above-mentioned collision point and the mesh vertex corresponding to it will be calculated in real time according to the normal direction and deformation force generated between the two. Based on this, the attenuation force corresponding to each mesh vertex will be further calculated according to the existing inverse square law, and the current attenuation force will be multiplied by the collision time between the two to obtain the corresponding speed of each mesh vertex when colliding, and the current speed will be further multiplied by the direction vector of the current mesh vertex, so that the vertex speed of each mesh vertex can be finally obtained. Further, the present invention can immediately calculate the local deformation degree of the current balloon model according to the current vertex speed and deformation time. In addition, it is also necessary to explain that in order to complete the recovery of the balloon model in a timely and effective manner, after a number of collision points are detected in real time through the above steps, the target vector corresponding to each current collision point will be obtained, and the initial position and the change position corresponding to the current target vector will be detected synchronously. At the same time, the target offset between the two is calculated in real time, and the elastic coefficient corresponding to each current collision point is further matched in real time in the existing elastic coefficient database. Based on this, the restoring force required by the current balloon model is finally calculated according to the current target offset and the current elastic coefficient. On this basis, the restoring force vector required for each current collision point is further calculated according to the current restoring force. Furthermore, based on the above-mentioned vertex speed, the current restoring force vector is updated accordingly to generate the corresponding recovery speed. Finally, the current balloon model can be smoothly restored according to the current recovery speed and the restoring force, which correspondingly improves the user experience.
