The process of animating wallpaper typically involves these general steps.
You can create an animation of scrolling wallpaper using one of a variety of computer graphics applications. Many such applications, including Blender and Sketchup, are available for free. (The 3ds Max program referenced in this article is not free.) The process of animating the wallpaper typically involves these general steps, regardless of what program you use: creating the surface on which to apply the wallpaper; applying the wallpaper to the surface; then creating “keyframes” of the surface at different screen locations. Keyframes are snapshots of an animation sequence. Your graphics software computes the frames in between your keyframes, and does so based on those keyframes.
1. Open Blender, then resize the default cube to accommodate a wallpaper bitmap image: right-click the cube to select it, then select the scale manipulator mode. Scale up the cube so its dimensions along the green-red axes look large in the viewport.
2. Enter the texture context of the shading buttons by pressing the corresponding buttons in the panel. Or press “F5,” then “F6.”
3. Select “Image” in the “Texture type” drop-down list in the Texture panel. In the “Image” panel, press “Load,” then load the image file of a wallpaper texture from your hard drive.
4. Press the numeric keypad’s “0” key to switch to the camera’s point of view. Position the cube at the left of the viewport, then press “I,” then “Loc” to make an animation keyframe for frame one.
5. Increase the time slider to frame 100, then move the cube to the right of your screen. Create another keyframe by pressing “I,” then “Loc.”
6. Render the animation by pressing “Control-F12.” Allow time for the animation to be rendered. Then, play the completed animation of the scrolling wallpaper by pressing “Control-F11.”
7. Use the square tool to draw a square on the red-green plane, then press “Space,” then “B” to enter the texturing mode.
8. Select a wallpaper texture from the “Sketchy” category, then click the square to fill it with that texture.
9. Make an animation keyframe by selecting “View,” then “Animation,” then “Add Scene.”
10. Enter Walk mode by choosing “Walk” from the “Camera” menu, then click in the viewport and drag upward to walk over the wallpaper.
11. Create another keyframe using Step 3’s instructions, then play the animation of the scrolling wallpaper by selecting “View,” then “Animation,” then “Play.”
