求助两个曲面交线问题
本帖最后由 沉寂小新 于 2010-9-2 10:11 编辑(y-x+1)*(1-1/sqrt((y-x+1)^2+z^2))+(x+1)*(1-1/sqrt((x+1)^2+z^2))=0
-(y-x+1)*(1-1/sqrt((y-x+1)^2+z^2))+(1-y)*(1-1/sqrt((1-y)^2+z^2))=0
请各位高手指点一下,这两个曲面的交线怎么画? http://forum.vibunion.com/thread-9707-1-1.html 回复 messenger 的帖子
这个方法我用过,但是不行,这两个曲面方程是隐函数,所以那种方法好像不行啊!
顶一下
2楼中曲面和曲面相交已经写成显函数形式了,我现在遇到这么个
gama1=0.04;
gama2=0.2;
miu1=0.01;
miu2=1.5;
k=0.2;
delta=0.9;
beta=0.1;
xi=0.5;
f=0.05;
g2=@(x,z,y) (delta.*z-3/4*k.*z.^3).^2+(2*gama2.*z).^2-miu2.*y.^2;
f3=@(x,z,y) f.^2./(4.*y.^2)-(gama1./2).^2-(3/8.*beta.*y.^2+(xi./4-(x-1))).^2-gama1.*(miu1./2+miu1.*k.*z.^2*3/8)*2.*gama2.*z.^2./(miu2.*y.^2)-2.*(3/8.*beta.*y.^2+(xi./4-(x-1))).*(miu1./2.*z+miu1.*k.*z.^3*3/8).*(delta.*z-3/4.*k.*z.^3)./(miu2.*y.^2)-miu1.*gama1.*gama2.*z.*(delta.*z-3/4.*k.*z.^3)./(miu2.*y.^2)-2.*(3/8.*beta.*y.^2+(xi./4-(x-1))).*miu1*gama2^2.*z.^2./(miu2.*y.^2);
这种由隐函数确定的交线该怎么求??
