및 을 Bessel사용하여 3D 기능을 그리고 있습니다 . 내가 하려는 것은 3D 함수의 투영인 3D 상자 위에 플롯을 그리는 것입니다.pgfplotsgnuplot
플롯 을 사용하려고 생각했지만 contour gnuplot높은 number윤곽선을 사용하더라도 다음 이미지에서 볼 수 있듯이 투영의 전체 표면을 채울 수 없습니다.
간격을 피하고 투영을 원활하게 채우는 방법에 대한 아이디어가 있습니까?
이미지는 다음 코드를 사용하여 만들어졌습니다.

답변1
등고선 플롯 대신 원래 플롯의 포인트 메타를 사용하여 상수를 플롯합니다.

극좌표를 사용하면 IMHO 결과가 더욱 매력적입니다.
