NUMERICAL SPACE / CASSINI

	The equation of Lemniscate of Bernoulli is ; (x2 + y2)2 - a2(x2 - y2) = 0 I got this 3D image by replacing "y2" with "y2 + z2 - 16". Scene file : lpcslmns.txt Lemniscate of Bernoulli / 27k / May 2003 / by Tsutomu Higo
	For the equation of Lemniscate of Bernoulli ; (x2 + y2)2 - a2(x2 - y2) = 0 I replaced only former member's "y2" with "y2 + z2 - 16". Scene file : lpcslmnd.txt Slightly modified Lemniscate / 30k / May 2003 / by Tsutomu Higo

For getting eggs I replaced "y2" with "y2 + z2". The function makes not only eggs but also silkworm cocoons. Scene file : lpcsegg.txt

Cassinian eggs / 26k / June 2003 / by Tsutomu Higo

For the equation of 3D Cassinian Ovals I mage (x2 + y2 + z2)2 - 4z2x2 - c4 = 0 I slightly reduced the middle member gradually. You can see that the shape may become to the sphere. Scene file : lpcscart.txt

Modifying the equation / 31k / June 2003 / by Tsutomu Higo

	For the above mentioned equation, which has four arms, I compressed the angle of coordinates around the axis. This technique may be applied generally for modifying the 3D images?! Scene file : lpcsaxis.txt Exchanging coordinates - Compressing rotation / 24k / May 2003 / by Tsutomu Higo
	For the same equation I rotated the cordinates around the axis in proportion to the length from the axis. Scene file : lpcsswrl.txt Exchanging coordinates - Swirling rotation / 16k / May 2003 / by Tsutomu Higo
	For the same equation I translated the cordinates along the axis in proportion to the squared length from the axis. Scene file : lpcsplbl.txt Exchanging coordinates - Parabolic translation / 18k / May 2003 / by Tsutomu Higo
