When it comes to molecular modeling, effectively presenting your results is just as important as conducting precise analyses. SAMSON’s Appear animation can help molecular modelers solve a common visualization problem: how to progressively reveal complex molecular structures in a clear, intuitive way.
Progressive appearance is often necessary for illustrating the inner workings of structural models, meshes, or labeled regions in presentations or videos. Whether you are unveiling a protein binding site or visualizing a labeled molecular pathway, creating animations with SAMSON's Appear feature makes it easier to tell your story.
What Is the Appear Animation?
The Appear animation is designed to make nodes gradually appear by reducing their transparency over time. This controlled approach applies to nodes with a transparency attribute, such as structural models, visual models, meshes, and labels. For nodes lacking a transparency attribute, the behavior is similar to the Show animation, providing a consistent visual experience.
It is worth mentioning that individual atoms and bonds do not have a transparency attribute. To make atoms or bonds appear progressively, you should apply the animation to their corresponding structural models.
How to Add the Appear Animation
Adding the Appear animation is straightforward:
- Select the nodes you want to animate.
- Double-click on the Appear animation effect in the Animation panel of the Animator.
This animation is divided into 4 keyframes to allow for full control:
- Between keyframes 1 and 2: Selected nodes are fully transparent.
- Between keyframes 2 and 3: Transparency decreases, making nodes progressively appear.
- Between keyframes 3 and 4: Nodes are fully opaque (no transparency).
You can move the keyframes as needed to align the animation with your presentation requirements.
Fine-Tuning the Animation
To customize the interpolation of parameters between keyframes, modify the Easing curve. This allows you to control the pace of transparency transitions, creating smoother or more dramatic appearances, depending on your visualization goals.
An Example in Action
To illustrate how the Appear animation works, here’s an example of progressively revealing a molecular scene:
Note on Interface Updates
If you have used older versions of SAMSON, you might notice an interface change reflected in the example animation above. While the Animation menu shown in the GIF is no longer present, all animations can now be accessed via the Animation panel in the Animator.
Whether you’re preparing a scientific presentation, publishing a molecular animation, or simply enhancing the clarity of your project, the Appear animation is an indispensable skill in your molecular modeling toolkit.
