For molecular modelers, effective visualization often plays a critical role in inspecting and communicating structural and dynamic properties of molecular systems. However, making parts of complex molecular models progressively visible can be challenging without proper tools. Here’s where the Appear animation effect in SAMSON can be invaluable.
The Appear animation is specifically designed for nodes that have a transparency attribute, such as structural models, visual models, meshes, and labels. It allows you to progressively render these nodes more visible by adjusting their transparency over time, which can be particularly useful for storytelling or highlighting specific molecular features during presentations.
Why use Appear?
The Appear animation helps tackle common issues molecular modelers face:
- Need to gradually reveal complex molecular structures, such as proteins or complexes, while maintaining focus on specific regions.
- Difficulty in visually distinguishing different structural components through static views.
- Creating clear, step-by-step animations for presentations or educational materials.
Additionally, this animation provides a flexible way to define levels of transparency, ensuring precision and customization for your projects.
How to apply the Appear animation
Here are the steps to add this effect in SAMSON:
- Select the nodes you wish to animate.
- Double-click on the Appear animation effect in the Animation panel of the Animator.
Once applied, the animation will have 4 keyframes by default:
- Keyframes 1 to 2: The selected nodes will be fully transparent.
- Keyframes 2 to 3: Transparency decreases progressively, revealing the nodes.
- Keyframes 3 to 4: The nodes become completely opaque, showcasing full visibility.
You can adjust the timing and spacing of these keyframes to control the speed and smoothness of the transparency transition. Additionally, by modifying the Easing curve, you can customize how the transparency changes between frames, adding more fine-tuned control to your animation.
Example in action
The power of this technique lies in its ability to clearly communicate molecular data. For instance, showcasing a large protein complex by gradually introducing its components can help viewers better understand the individual parts before seeing the whole. Want more clarity? Use the Appear animation to highlight specific models like helices or ligands, drawing attention right where it’s needed.
Notes
Though the Appear animation supports nodes with a transparency attribute, note that individual atoms and bonds do not have such an attribute. In this case, you will need to apply the effect to their corresponding structural models instead.
Lastly, keep in mind that the animation menu shown in earlier video tutorials is no longer present. All animations, including Appear, are now accessible via the Animation panel within the updated Animator interface.
