Adding texture maps Presentation Transcript

  • 1. Animation with Blender
  • 2.  Everything for this project is taken from NASA’s Blue Marble Project  http://visibleearth.nasa.gov/view_cat.php?categoryID=1 484  The BMNG Raw Bathymetry provides the depths of the Oceans to the map  http://visibleearth.nasa.gov/view.php?id=73963  The BMNG Raw Topography provides the topography of the Earth’s Surface (ie Mountains, Plains, etc)  http://visibleearth.nasa.gov/view.php?id=73934
  • 3.  Below are the links to the March 2013 maps of the Earth’s surface:  March, Blue Marble Next Generation  http://visibleearth.nasa.gov/view.php?id=73992  March, Blue Marble Next Generation w/ Topography  http://visibleearth.nasa.gov/view.php?id=74293  March, Blue Marble Next Generation w/ Topography and Bathymetry  http://visibleearth.nasa.gov/view.php?id=73630  And don’t forget the clouds  http://visibleearth.nasa.gov/view.php?id=74293  Also see http://planetpixelemporium.com/planets.html
  • 4. 1. Select the object 1. A UV shpere 2. In the Toolshelf 1. Click smooth 3. Add a new Material 1. No changes need to be made to this material as it is just a holder for this activity. 4. Switch to Textures and add a new Texture 1. This creates a texture in slot one
  • 5.  Name the Texture  Earth_colours  Change the Texture Type to  Image or Movie  In the Image sub-section  Open image  Find the image you want to use
  • 6.  Under Image Mapping change;  Extension to Extend  This describes how the 2D map is extended to cover the 3D object.  NB: I used Clip initially, but that left a line, so I swapped to extend  Under Mapping change;  Projection to Sphere  This maps the 2D image to the 3d object.
  • 7. This is an example of the Earth with just the surface colouring. TestRender1
  • 8.  In the Second texture slot;  Create a new texture  Name it Topology  Set the type to Image or Movie
  • 9.  Under Image Mapping change;  Extension to Extend  Under Mapping change;  Projection to Sphere
  • 10.  Under the Influence sub-section;  Untick color  Tick Normal
  • 11. This is an example of the Earth with the surface colouring and a topology normal map for the surface. TestRender2
  • 12.  The procedure to add the Bath map is the same as the Topology map, but  Use Texture slot 3  Change the value in the Normal map to -1
  • 13. This is an example of the Earth with the surface colouring, a topology normal map for the surface, and a bath map for the oceans. TestRender3
  • 14.  Adding the cloud texture is the same as the Topology map, but  Use Texture slot 4  Tick Emit and change the value to 0.5  Set Color to .4
  • 15.  Change the Horizon Color to black  Tick the Environment Lighting  Tick the Stars  Adjust the Star setting as you choose
  • 16.  Extend the length of the animation to 360 frames  Add keyframes for rotation at  Frame 1  Frame 360  Set Z-Rotation to 360
  • 17. This is a single image, with clouds, normal maps and surface colours. TestRender4
  • 18.  Switch the 3D View to Graph Editor.
  • 19.  Hovering over the Graph Editor window  Press A to select all  Press V to open the vector context menu  And select Vector.  This will smooth the Revolving of the Earth Animation
  • 20. Don’t forget to save the output! You should have a 360 frame animation of the Earth revolving. Final Render
