...lot and I'm struggling to get the lighting correct. Currently the surface gets plotted, but is very 'shiny'. On rotating the view, I get to see parts of the surface - but overall I don't see much detail because of the spotlight like lighting. I've played around with the specular, ambient and diffuse but I can't bring out the details of the surface. Could anybody point me to some examples of how to make a plain matte surface, which isn't obscured by specular reflections?

...on the viewpoint at theta=0 and phi=30: > view3d(theta=0,phi=30) Next, I want to create a 2nd light source which diffuses red light from the front face. I thought I could do: >light3d(diffuse="red",theta=0,phi=0) but...the front side doesn't show any red-iness. Same goes for specular and ambient. What am I doing wrong here? How should the fron side show in red colour?

What is the simplest (namely: minimum number of libraries or conflicts) way to fill a polygon with a pattern? For example, suppose I have (in a graphic file, like a jpeg) the drawing of an "X". Then I fill a polygon (like a triangle) with this pattern, and get something like: X XXX XXXXX XXXXXXX (where the border "X"s could be truncated). I searched the rimage

Hello, Could someone suggest a package/way to make a 3D raster plot of the Earth (with continent boundaries), and then make a "cut" or "slice" of it such that one can also visualize some scalar quantity as a function of the Radius/Depth across that given slice ? Formally, I would have a given, fixed longitude, and a list of vectors {latitude, radius, Value} that would show

> It should be a 2D slice/plane embedded into a 3D space. I was able to come up with the plot, attached. My intention was to plot national boundaries on the surface of a sphere. And put the slice inside. However, I haven't (as yet) worked out how to get the coordinates for the boundaries. Let me know, if of any value. And I'll post the code. (But needs to be polished first)

Hi R Users, I have produced a simulated scatter plot of y versus x tightly clustered around the 45 degree line through the origin with the following code: x <- seq(1,100) y <- x+rnorm(100,0,10) plot(x,y,col="blue") abline(0,1) Is there some way to generate a 3-dimensional analogue of this? Can I get a similar simulated scatter plot of points in 3 dimensions where the points

Thanks for your idea. It should be a 2D slice/plane embedded into a 3D space. Could be static, I just need to make a single figure from it for illustration of the Earth together with its interior in 3D. So, the interior would be a slice in 2D along a fixed longitude. And along this 2D slice would be a heatmap. Again, embedded in 3D, since it would be shown as a slice of Earth in 3D. Duncan?s

My problem: After some time playing WoW (about 1-2 minutes) the whole screen turns white. Everything else seems to work perfectly, I still have sound and I still can interact with my character. I can even open a terminal (blindfolded) and type 'killall WoW.exe' to quit WoW and make the white screen go away. wine --version outputs 'wine-1.1.37' I use the propiertary nVidia drivers

Hi all! I recently got an ATI Radeon HD 3850 card and now noticed that with the fglrx driver many games that look well in AppDB do not run properly on this hardware (Supreme Commander ingame: flickering static garbage, Prince of Persia SoT has several issues that completely garble ingame graphics). Older games (not using shaders among other things) seem to run fine - need to do more testing

A reworked version of 3 out of 4 patches mentioned earlier. [1/4]: Fixes nearly all piglit vertprog testcases, due to now being able to pass the results on to the fragment shader. V2: rename samplers to texcoords. [2/4]: Fixes shader compiler assertion errors, as some source registers do not exist for certain operations. Fixes several piglit tests when mesa is compiled with --enable-debug [3/4]:
