How to Make 3D Billboard Videos on a Curved Screen in Blender
Creating 3D anamorphic billboard videos is a powerful way to grab attention in public spaces. Here’s a simple guide to producing these eye-catching effects using Blender.
Determine the size and height of the screen.
Identify the ideal viewing position.
Set the camera’s focal length and angle based on the viewer’s position.
Create a 3D model of the curved screen in Blender.
Separate the screen surface into a dedicated object.
Step 2: Set Up 3D Content
Import 3D models into the scene.
Apply appropriate lighting and materials.
Add animations to the content as needed.
Step 3: Project to the Screen
Use the UV Project Modifier to project the camera view onto the screen surface.
Adjust the projection to match the screen’s angle and shape.
Step 4: Adjust Materials and Edges
Set up the screen material to simulate a real LED display.
Add border loops around the screen to avoid image distortion.
Step 5: Render Test Frames
Render a few still images to test alignment and perspective.
Step 6: Create the Final Video
Make sure the camera is aligned with the intended viewer position.
Render the full video sequence using the UV-projected content.
Export the result as an MP4 video.
By following these steps, you can produce realistic and engaging 3D illusion videos for curved LED screens using Blender.
