Custom Force

Apply a custom force to simulated geometry.

输入

模式

How the force field is defined.

力场:

Define the force with a vector field and transformation spaces.

Transformation spaces can be:

自定义空间:

Defined by a matrix input.

世界空间:

Common world space.

物体空间:

Transform of a given object.

闭包:

Compute the force vectors with a closure during the time step.

Selection Field

Selection of points that the force is applied to.

Force Field

The force vector at each point, defined in Force Space.

Geometry Space Field

The space the geometry is transformed to before the field is evaluated.

Force Space Field

The space in which the output vector is computed.

Closure Closure

A closure that computes the force field on demand.

It has a Geometry input and output, receiving the geometry to which the force is applied. The output geometry may be modified, but any changes are temporary and only used during field evaluation. The input geometry is in simulation space.

It receives a To World Transform matrix which transforms from simulation space to world space.

The closure must output a Selection boolean field defining the points to which force is applied as well as a Force vector field which defines the actual force vectors in simulation space.

过滤

Comma-separated list of tags to limit the effect of the force. The force is only applied to geometries that have at least one matching tag.

输出

常力

Resulting effector bundle that should be stored in the simulation world.
