This is how we'll show vectors. 
      
          Normal vectors. 
        
          Vectors add head-to-tail. 
        
        
          Dot product. 
          
          More dot product. 
        
          Cross product. 
        
          A 3D coordinate space. 
          
          One space defined within another. 
      
          Plotting a point in a 3D space. 
      
          Nested transforms. 
          
          Merged into one transform. 
      
          Object in original position. 
          
          Displacement. 
          
          Displacement and scaling. 
          
          Displacement and non-uniform scaling. 
          
          Displacement and Rotation. 
          
          Displacement and Skewing.
