#### NUMERICAL SPACE / FRAME

I have tried various ways for drawing curved surfaces in this numerical space recentry. Polygon is not tried yet, but most general and least limited way for the purpose. So I planed treating polygon by a text editor and MS Excel.
As the first step of the plan, I generated some frames of triangles .

Now POVray 3.1 is available and expands the expression of numerical space very much. So this page is the last page by POVray 3.0 and the last chance for using halo, my favorite technique. So, I used poetic halo in all works on this page as the memory of POVray 3.0.

 I put triangles side by side spirally to form a pipe. You can exchange the number of triangles for one around in this scene file. Modifying the spiral pitch or the diameter makes various shapes from this structure. Scene file : lpfpipe.txt

 I made this cage by modifying the diameter of the pipe structure. Scene file : lpfcage.txt

 I bended the pipe structure to a circle for making this ring structure by triangles. The formation of the circle seems to generate a small error. In the calculation a number should be just 2. But for the accurate one circuration it must be a little bigger than 2. Scene file : lpfring.txt

 I extend the ring to this coil. Forming coil by ring or forming ring by pipe is not very interesting way. But making complex structure from simple structure helps us for understanding the figue. Scene file : lpfcoil.txt

 Objects made from pipe structure need surfaces for closing the edge. So I got the plane by putting triangles side by side. Straining is necessary for connecting with the pipe structure. Scene file : lpfdome.txt
