Adding a Texture Map
Everything for this project is taken from NASA’s Blue Marble Projecthttp://visibleearth.nasa.gov/view_cat.php?categ
oryID=1484
The BMNG Raw Bathymetry provides the depths of the Oceans to the maphttp://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

Add a material1. Select the object
1. A UV shpere
2. In the Toolshelf1. Click smooth
3. Add a new Material1. 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

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.
This is an
example of the
Earth with just
the surface
colouring.

This is an
example of the
Earth with the
surface colouring
and a topology
normal map for
the surface.

Adding the Bath mapThe procedure to
add the Bath map is the same as the Topology map, butUse Texture slot 3Change the value in
the Normal map to -1
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.
Test Render 3
Add the cloud textureAdding the cloud
texture is the same as the Topology map, butUse Texture slot 4Tick Emit and
change the value to 0.5
Set Color to .4
Tweak the World settingsChange the Horizon
Color to blackTick the
Environment Lighting
Tick the StarsAdjust the Star
setting as you choose
Extend the length of the animation to 360 frames
Add keyframes for rotation atFrame 1Frame 360
Set Z-Rotation to 360
Adjust the length of the animation
This is a single
image, with
clouds, normal
maps and
surface colours.
Test Render 4
Smoothing the AnimationSwitch the 3D View
to Graph Editor.
Smoothing the AnimationHovering over the
Graph Editor windowPress A to select allPress V to open the
vector context menuAnd select Vector.
This will smooth the Revolving of the Earth Animation
Don’t forget to
save the output!
You should have
a 360 frame
animation of the
Earth revolving.
