Tensores internos¶
As stated in the introduction, cloth physics are simulated through Tensores connecting vertices on the surface of a mesh. But these springs only interact on the surface and only apply to 2D surfaces. 3D or Internal Springs can be used to make a mesh behave similarly to a Soft Body. Internal springs can be enabled by toggling the checkbox in the Internal Springs panel header.
- Longitud máx inicial
The maximum length an internal spring can have during creation. If the distance between internal points is greater than this, no internal spring will be created between these points. A length of zero means that there is no length limit.
- Desviación máx inicial
The maximum angle that is allowed to use to connect the internal points can diverge from the vertex normal.
- Comprobar normales de superficie
Requires the points the internal springs connect to have opposite normal directions.
- Tensión
Qué tan resistente será el material al estiramiento.
- Compresión
Qué tan resistente será el material a la compresión.
- Grupo de vértices
The Tension and Compression of internal springs can be controlled via a Vertex Group to specify which the portions of the mesh have internal springs or the spring strength.
- Tensión máx
Maximum tension stiffness value.
- Compresión máx
Maximum Compression stiffness value.
Presión¶
Cloth pressure allows the simulation of soft-shelled objects such as balloons or balls that are filled with a type of fluid. This fluid is modeled as a gas; to emulate an incompressible liquid set Pressure Scale as high as possible without breaking the simulation. Cloth pressure can be enabled by toggling the checkbox in the Pressure panel header.
Nota
Non-manifold meshes will work with cloth pressure however, pressure will escape out of the mesh holes and cause drifting or propulsion forces. One way to get around this is by using the Vertex Group to exclude the non-manifold portions of the mesh.
- Presión
The uniform pressure that is constantly applied to the mesh. This value is specified in units of Pressure Scale, and can be negative to simulate implosions or any other case where an object has outside pressure pushing inwards.
- Volumen personalizado
Use the Target Volume parameter as the initial volume for the cloth, instead of computing it from the mesh itself.
- Volumen objetivo
The mesh volume where the inner/outer pressure will be the same. If set to zero, changes in the volume of the object will not affect pressure.
- Escala de la presión
Ambient pressure (in kPa) that exists both inside and outside the object, balancing out when the volume matches the target. Increase the value to make the object resist changes in volume more strongly.
- Densidad del fluido
Specifies the density of the fluid contained inside the object (in kg/liter = 1000 kg/m3, use 1 for water), used to generate a hydrostatic pressure gradient that simulates the weight of the fluid. If the value is negative, it instead models buoyancy from a surrounding fluid.
The fluid is not actually simulated, so while the setting helps to achieve a more plausible object shapes at rest, it cannot create realistic fluid dynamics effects. It can also be used to give more weight to a soft body like object with heavy and sufficiently flexible filling, even if it is not a fluid by itself.
The volume of the object is not preserved. If that is desired it should be used together with Pressure Scale. Fluid density times object size times 50 is a good start value for Scale to make sure that no more than 10% volume change if the object does not experience higher acceleration than standard gravity.
- Grupo de vértices
Cloth pressure can be controlled via a Vertex Group to specify which the portions of the mesh to apply pressure. Zero weight means no pressure while a weight of one means full pressure.
Note, faces with a vertex that has zero weight will be excluded from the Target Volume calculation.
