The combined graphics could by obtained as a collection of simple objects called primitives. The primitive can be: point, line, ellipse, cube, etc. To draw the primitives one can use the function Show[Graphics[ primitive].
Primitive | Graphical object |
Point[ {x,y}] | Defines a planar point with co-ordinates {x,y} |
Line [ { {x1,y1},{x2,y2},...}] | Defines a broken line by its vertices |
Rectangle[{xmin, ymin},{xmax, ymax}] | Defines a rectangle by its vertices |
Polygon[ { {x1,y1},{x2,y2},...}] | Defines a planar polygon with co-ordinates of vertices {x1,y1},{x2,y2}, ... |
Circle [ {x,y} , r ] | Defined a circle with co-ordinates of the center and its radius |
Disk [ {x,y} , r ] | Defines a disk with co-ordinates of the center and its radius |
Disk [ {x,y} , {r1,r2} ] | Defines an ellipse |
