Analytical Geometry with POV-Ray

Solids III 

Sphere, Ellipsoid, Cylinder,  
Cone, Truncated Cone  


Sphere
with center M and radius R

sphere{ M, R  
        pigment{ color White }}


Ellipsoid with center M and radii Rx,Ry,Rz:

sphere{ o, 1 scale<Rx,Ry,Rz>
        translate M
        pigment{ color Green transmit 0.5}}
Sphere and Ellipse
Scene for POV-Ray: ".txt" file or ".pov" file

Cylinder with centers of both ends M1, M2 and radius R:

cylinder{ M1,M1, R
                 pigment{ color Green transmit 0.5}}
Cylinder
Scene for POV-Ray: ".txt" file or ".pov" file

Cone with base center M1, base radius R1 and top point M2:

cone{ M1,R1, M2, 0
      pigment{ color Green transmit 0.5}}


Truncated cone, centers of the ends M1, M2, radii R1, R2:

cone { M1,R1, M2, R2
      pigment{ color Green transmit 0.5}} 
Cone and truncated cone.
