Re: [Matplotlib-users] mplot3d: plot_surface() and contour on grid?

Hi Matthias, I have a similar patch lying around somewhere, and I will try to apply it soon. I've been terribly busy lately, but I expect some nice mplot3d enhancements in the very near future. Regards, Reinier On Wed, Dec 2, 2009 at 4:22 PM, Matthias Michler wrote: > Hi Andrew, > > do you have

Hi Andrew, do you have any idea if the patch (or a part of it) may get a part of matplotlib-svn some day? Kind regards, Matthias On Friday 09 October 2009 23:25:28 Andrew Straw wrote: > Matthias Michler wrote: > > Hello list, > > > > I'm not an expert in axes3d, but in case the feature which Ni

Thanx all, Can it be used to do a projection not only on the xoy axis but also on the xoz and yoz? N 2009/10/9 Andrew Straw > Matthias Michler wrote: > > Hello list, > > > > I'm not an expert in axes3d, but in case the feature which Nicolas > requested > > is not possible in an easy manner up to

Re: [Matplotlib-users] mplot3d bars3d demo

The bug was fixed on the 0.99.x branch, not in 0.99.0 (which predates the fix). The fix should, however, make it into the forthcoming 0.99.1 release. Cheers, Mike Nicolas Bigaouette wrote: > I have reported that issue on the tracker at the end of July. You can > fin dit here: > http://sourcef

Re: [Matplotlib-users] mplot3d bars3d demo

I have reported that issue on the tracker at the end of July. You can fin dit here: http://sourceforge.net/tracker/?func=detail&atid=560720&aid=2830483&group_id=80706 It's supposed to be fixed in 0.99... are you sure you are using it? I remember trying it just after the bug was closed with an svn

Re: [Matplotlib-users] mplot3D plot_surface colors

It's important to note that we're not, as far as I'm aware, considering anything lighting or ray-tracing-like yet. I'm not sure that Phong shading actually makes sense without doing that. The Gouraud shading we're in the process of implementing uses only explicit colors specified in the plot,

Re: [Matplotlib-users] mplot3D plot_surface colors

Its great news that the 3D is receiving more polish :) After reading on wikipedia, wouldn't it be nicier to have Phong reflection[1] instead of Gouraud? Maybe it would be too hard, as the Gouraud seems to be implemented directly in Agg (from what others just said...) Anyway, just a suggestion ;)

Re: [Matplotlib-users] mplot3D plot_surface colors

Hi JJ, Thanks for the examples! I indeed suspected the anti-aliasing as well. I'll include an option for linecolors = facecolors soon (probably this weekend); it seems to be a good solution. After that I'll try to implement usage of the Gouraud shading, although I fear that this will not look nic

Smooth Gouraud shading on surface plots is being worked on, but is not yet implemented. Mike German Ocampo wrote: > Hello > > Are there some way to take out the gridlines from a surface in mplot3D > and get a smooth colour change? > > Thanks > > German > > ---
