search for: isosurfac

I am looking for examples of how to plot with contour3d() to a PNG or PDF file, add axes and other elements to the isosurface plot, and use contour3d in conjunction with lattice. Regarding lattice, I'm not necessarily looking for conditioning on the data shown in the isosurface plots, just a way to show multiple plots in one figure and label them. I am new to the packages misc3d and rgl. Thanks, Scott Waichler P...

Dear All, I tried to draw 3 filled.contour plots on one page, but failed. It returns "Error in plot.new() : Figure margins too large". Can anyone help me to do this. BTW, does anyone has the experience to draw a isosurface with R? Dr Zhiqiang Cui School of Geography and Environmental Sciences The University of Birmingham Edgbaston, Birmingham B15 2TT

...xample referenced above. It would seem most software capable of this type of thing is proprietary (and perhaps for good reason if it is a difficult problem to solve). I've put together a very simple 6x6x6 cube with non-zero values internal to it representing the plume. I wondering if an isosurface where "conc" = 0.01 can be rendered in 3D and then if a "bite" or wedge can be removed from the 3d object exposing the higher concentrations inside as discussed above? x<-c(1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3...

The misc3d package provides a small collection of mostly rgl-based functions for 3D data: contour3d Uses rgl to render isosurfaces, or three-dimensional contours, computed by the marching cubes algorithm. image3d Crude 3d analog of image() using rgl to plot points on a three dimensional grid representing values in a three dimensional array. Assumes high values are inside and uses alpha ble...

Release 0.4-0 of package misc3d is now available from CRAN. This package provides a small collection of functions for 3D plotting, including 'contour3d' for computing and rendering 3D contours or isosurfaces and 'parametric3d' for rendering parameterized surfaces. A major change in this release is that rendering in standard and grid graphics is now supported in addition to rgl. To support rendering in standard and grid graphics the package includes some functions for managing and rendering...
