1.3.1 mtg.plot3d

mtg.plot3d(formula)

:: formula のグラフを描画する.

mtg.plot3d(formula | options)

:: formula のグラフを描画する. options で描画範囲などを指定する.

return

リスト

formula

式 または quote 型データ. x, y の関数.

オプション
domain

リスト. [[xmin,xmax],[ymin,ymax]]

mesh

自然数. メッシュの分割数.

fit

1 の時に (max+min)/2 が z=0 となるように移動する.

[1210] import("mt_graph.rr");
[1211] mtg.test2();
[1210] import("mt_graph.rr");
[1211] mtg.plot3d(x^2-y^2);
[1210] import("mt_graph.rr");
[1211] mtg.plot3d(x^2-y^2 | domain=[[-1,1],[1,1]]);
[1210] import("mt_graph.rr");
[1211] def myfunc(X,Y) { if (X*Y < 0) return 0; else 1;}
[1212] mtg.plot3d(quote(myfunc(x,y)*x*y));

mtp.parametric_plot3d(formula | options)

:: formula のグラフを描画する. options で描画範囲なのを指定する.

return

リスト

formula

式 または quote 型データのリスト. s, t の関数.

オプション
domain

リスト. [[xmin,xmax],[ymin,ymax]]

mesh

自然数. メッシュの分割数.

fitting

値を 0 とすることで, z 方向の縮尺の自動調整をしない.

[1210] import("mt_graph.rr");
[1211] mtp.test5();   /*  Klein bottle (8 figure) */
[1210] import("mt_graph.rr");
[1211] mtp.parametric_plot3d([s,t,s^2-t^2]);
[1210] import("mt_graph.rr");
[1211] def myfunc(X,Y) { if (X*Y < 0) return 0; else 1;}
[1212] mtp.parametric_plot3d([s,t,quote(myfunc(s,t)*s*t) | fitting=0);
