Hi Jason and everyone,Thank you very much for your reply.Now I have a function or a set of data depending all the three coordinates x, y, z.In other words, there is a corresponding value at every point in 3 dimensional space, which maybevaries from -1 to 1. I want use color to represent the values in every point in 3D space.For example in a room there is a temperature value at every point in 3D space of the room, I want describe the temperature value by color for every point in the room.I really haven't find a proper example figure from internet.thanks,YC - 原文 - 发件人: Jason Grout 主 题: Re: 回复: [sage-support] Re: 3D plot in sage时 间: 2010年3月16日 05:19:05On 03/12/2010 05:43 AM, wxu...@sohu.com wrote:> Actually I do need them to be plotted by color.> it seems that sage is not designed for this way.> could anyone give some information about> what open source software can do this?> I really don't understand what sort of plot you want.

Actually I do need them to be plotted by color.it seems that sage is not
designed for this way.could anyone give some information aboutwhat open source

If you didn't need them to be plotted by color, then you could use the
contour option, like in the doc examples:
sage: implicit_plot3d((x^2 + y^2 + z^2), (x, -2, 2), (y, -2, 2), (z, -2,
2), plot_points=60, contour=[1,3,5])

Re: 回复: [sage-support] Re: 3D plot in sage
One option is several implicit plots, colored by value, i.e. something
like:
var('x,y,z')
f=cos(x)*cos(y)+cos(y)*cos(z)+cos(z)*cos(x)
imps = []
plot_range = srange(0,3,.75)
color_range = [i/N(len(plot_range)) for i in range(len(plot_range))]
for i,q in enumerate(plot_range):
red = color_range[i]
imps.append(implicit_plot3d(f-q==0, (x, -2, 2), (y, -2, 2), (z,
-2, 2), opacity = .5, rgbcolor = (red,0,1-red)))
show(sum(imps))
