Day 18: Blender tutorial for making illustrations - Drawing Biological Processes (e.g., Cell Division) in Blender

Objective:

Learn how to visually represent a biological process like cell division using Blender, including basic animation to showcase different stages of the process.

Step-by-Step Guide:

1. Open Blender and Set Up Your Workspace
• Open Blender and reset the default scene if needed.
• Use a top-down or front orthographic view (press 1 or 7 on the numpad) to work on a 2D plane.
2. Create Basic Shapes for the Cells
• Go to Add > Mesh > Circle to create the first cell.
• In the Properties panel, adjust the circle's vertices to make it smooth (about 32 vertices).
• Scale the circle to the desired size by pressing S and adjusting it.
3. Duplicate the Cell for Division
• Select the cell (A to select all if necessary), and duplicate it using Shift + D.
• Move the duplicated circle slightly to the side to start representing the process of division.
4. Shape the Cells for the Dividing Stages
• Press Tab to go into Edit Mode. Select the circle’s vertices, and use proportional editing (O) to reshape the cell into a more oval form, simulating the stage where the cell begins to divide.
• Repeat this step for the duplicated cell to create a pair of dividing cells.
5. Animate the Cell Division
• In the Timeline panel at the bottom, insert keyframes (I > Location) for the initial position of the two cells.
• Move the timeline slider forward, then slightly adjust the position of the duplicated cell, representing the gradual separation of the two cells.
• Insert another keyframe at the new position.
• Repeat this to create the entire animation of a cell dividing into two over a few seconds.
6. Adding Colors
• Go to the Shading tab, and select the cells. Assign a new material to them.
• Choose a color that represents the cells (e.g., green for plant cells or light blue for animal cells).
• Apply the color to both the original and duplicated cells.
7. Enhance the Scene with Labels and Arrows
• Add text labels to indicate stages like "Interphase," "Prophase," "Metaphase," etc., by going to Add > Text.
• Use Add > Mesh > Arrow to add arrows indicating the direction of the division process. Scale and position them appropriately.
8. Add Camera Movement
• Press Shift + A and add a Camera. Position it to capture the entire process.
• Animate the camera to zoom in or pan across the scene by inserting keyframes (I > Location and Rotation) at different points in the timeline.
9. Render the Animation
• In the Output Properties tab, set the desired resolution (e.g., 1080p) and select the output format (MP4 or AVI).
• Choose the frame range to render (e.g., frame 1 to 100).
• Click Render > Render Animation to start the rendering process.
10. Review and Refine

• Once the render is complete, play the animation to ensure smooth transitions and that the cell division process is clear.
• Make adjustments if needed (e.g., speed of division, camera angles).

Outcome:

You will have a simple animated illustration of a biological process, such as cell division, with smooth transitions between different stages. You can now start using similar techniques for other biological processes.

This sets the foundation for more complex educational content, including adding your voiceover and further refining the visual style.
