And deforming the tent model according to the second material type to obtain the collapsed tent model, as shown in fig. 16, which is a schematic diagram of the collapsed tent model.

In an alternative embodiment, a morphing animation of the tent model may be created to present the collapse process of the tent model.

The texture can be triangular surface texture or quadrangular surface texture.

In an optional embodiment, the triangular surface texture of the surface of the original model may be subjected to surface conversion to obtain a quadrangular surface texture; the surface of the original model can be changed into four-corner surface texture to obtain triangular surface texture.

In another alternative embodiment, since the solving stability and speed of the triangular surface in the system (vel lum) of the three-dimensional software (houdini) are better than those of the four-corner surface, the surface of the original model can be converted into the triangular surface by adding the triangular surface-turning nodes in the node flow, so as to obtain the computational model, as shown in fig. 17, the schematic diagram of the computational model with the surface being the triangular surface is shown.

In another optional embodiment, a surface-to-surface parameter may be set in a surface-to-triangular-surface node in the node flow, where the larger the value in the surface-to-surface parameter is, the smaller the number of triangular surfaces on the obtained calculation model surface is, and the smaller the value in the surface-to-triangular-surface parameter is, the larger the number of triangular surfaces on the obtained calculation model surface is. It should be noted that the number of triangular surfaces on the calculation model has a direct relationship with the effect obtained by the deformation process, and when the number of triangular surfaces is larger, the effect after the deformation process is richer, but the calculation speed of the deformation process is also reduced, so that reasonable surface conversion parameters need to be set to control the number of surfaces of the model and the calculation speed of the model.

In an alternative embodiment, in order to prevent the calculation model from deforming as a whole, a constraint point may be set in advance on the calculation model to control the part of the constraint point in the calculation model not to deform, for example, fig. 16 is a schematic diagram of a second model deformed after the constraint point is not added, and fig. 18 is a schematic diagram of a second model deformed after the constraint point is added, which does not deform as a whole due to collapse.

In another alternative embodiment, the second constraint condition may be set as a constraint of a certain region in the computational model, and a deformation animation in which the original model is deformed into the second model may be created by selecting a point in the region as a constraint point and processing a deformation path of the computational model based on the constraint point.
