Molecular design and modeling often involve handling complex systems. But when models include animations, navigating the associated attributes can become daunting. In this blog post, we break down the animation attribute space in SAMSON’s Node Specification Language (NSL) to help you streamline your workflow.
Why Animation Attributes Matter
Animation attributes in SAMSON allow you to define and manipulate properties specific to animation nodes. By using these attributes effectively, you can control the visibility, selection status, names, and more for animation components in your molecular models. This not only simplifies model management but also saves time when working with large datasets.
The Basics of Animation Attributes
In SAMSON’s NSL, animation attributes belong to the animation attribute space (short name: an). These attributes apply exclusively to animation nodes and are inherited from the generic node attributes. Here’s a summary of some key animation attributes and their uses:
| Attribute Name | Short Name | Possible Values | Examples |
|---|---|---|---|
| hidden | h | true, false | an.h, not an.h |
| name | n | strings in quotes | an.n "A", an.n "L*" |
| selected | — | true, false | an.selected, not an.selected |
| selectionFlag | sf | true, false | an.sf false, an.sf |
| visibilityFlag | vf | true, false | an.vf false, an.vf |
| visible | v | true, false | an.v, not an.v |
A Closer Look at Key Attributes
hidden
The hidden attribute determines whether an animation node is hidden. It accepts true or false as values. You can toggle it with expressions like an.h to hide, or not an.h to unhide the node.
name
The name attribute is used to assign or filter nodes by their names. It accepts strings enclosed in quotes. For example, an.n "A" targets animation nodes with the name “A,” while wildcard usage like an.n "L*" matches names starting with “L.”
visible
The visible attribute controls whether the node is currently visible. It is similar to hidden, but reflects the actual visibility state of the node. Expressions such as an.v or not an.v are used to query or modify this property.
How to Leverage Animation Attributes
Whether you’re organizing an elaborate biological animation or highlighting specific regions in motion for presentations, mastering these attributes can be transformative. For example:
- Hide all animation nodes in a rendering to get a clearer view of static molecular structures by toggling
an.hacross nodes. - Quickly select animations of interest by filtering based on
an.nand using a consistent naming convention. - Ensure all relevant animations are visible during simulations by verifying their
visibleandvisibilityFlagstates.
