Limitar posicionamento#

Um objeto ou osso desconectado pode ser movido em torno da cena ao longo dos eixos, X, Y e Z. Esta restrição pode limitar a quantidade de movimento permitido aos objetos ao longo de cada um dos eixos, através da definição de margens mais baixas e / ou mais altas.

The limits for an object are calculated from its origin, and the limits of a bone, from its root.

É interessante notar que mesmo que a restrição afete os limites da localização visual e renderizada de seu proprietário, o bloco de dados do proprietário ainda permitirá (por padrão) que o objeto ou osso tenha ou receba coordenadas fora das amplitudes máxima e mínima definidas. Isto podem ser visto em seus painéis de propriedades de Transformação.

When an owner is selected and attempted to be moved outside the limit boundaries, it will be constrained to those boundaries visually and when rendered, but internally, its coordinates will still be changed beyond the limits. If the constraint is removed, its ex-owner will seem to jump to its internally specified location.

Similarly, if its owner has an internal location that is beyond the limits, dragging it back into the limit area will appear to do nothing until the internal coordinates are back within the limit threshold (unless you enabled the Affect Transform option, see below).

A definição de valores iguais como amplitudes para Mínimo e Máximo para um eixo, travará efetivamente o movimento do proprietário ao longo deste eixo específico… Ainda que isso seja possível, a utilização das Propriedades de transformação para o travamento de eixos é bem mais simples e provavelmente, bem mais fácil.

O painel da restrição do tipo Limitar localização.#

Minimum X, Y, Z

These buttons enable the lower boundary for the location of the owner’s origin along, respectively, the X, Y and Z axes of the chosen Space. The number field below them controls the value of their limit. Note that if a min value is higher than its corresponding max value, the constraint behaves as if it had the same value as the max one.

Maximum X, Y, Z

These buttons enable the upper boundary for the location of the owner’s origin along, respectively, the X, Y and Z axes of the chosen Space. Same options as above.

Affect Transform

As pointed out before by default, even though visually constrained, the owner can still have coordinates out of bounds (as shown by the Transform panel). Well, when you enable this checkbox, this is no longer possible – the owner’s transform properties are also limited by the constraint. However, note that, the constraint does not directly modify the coordinates: you have to select its owner one way or another for this to take effect…

Owner

This constraint allows you to choose in which space to evaluate its owner’s transform properties. See common constraint properties for more information.

Influência

Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
