Crash when displaying / rasterizing graphics with textures at high resolutions


CAUTION/Disclaimer: execution of some of the code below can result in a complete crash of Mathematica or even your system. Save all your work and do not try in a productive situation.


For a graphical application, I need to export graphics containing several hi-res textures at large image sizes.


Consider the following (minimal example) code wich is largely harmless:


Graphics[{Texture[Graphics[Circle[]]], 
  Polygon[{{0, 0}, {1, 0}, {1, 1}, {0, 1}}, 
   VertexTextureCoordinates -> {{0, 0}, {1, 0}, {1, 1}, {0, 1}}]}, 
 ImageSize -> 400]



But upping ImageSize past a given (probably hardware-dependent, in my case ~4000) threshold will crash the frontend+kernel


Graphics[{Texture[Graphics[Circle[]]], 
  Polygon[{{0, 0}, {1, 0}, {1, 1}, {0, 1}}, 
   VertexTextureCoordinates -> {{0, 0}, {1, 0}, {1, 1}, {0, 1}}]}, 
 ImageSize -> 4000]

To make things worse, this also seems to depend on the graphics driver version. I use a NVIDIA GTX 485M card, and with the 296.10 driver, I can go up to about ImageSize -> 8000 while with any newer driver version the system stalls at ImageSize -> 4000.


Does anyone know a workaround? Always reverting to an obsolete driver (which e.g. does not work with CUDALink anymore) is not optimal.


Addendum: Question, Part Two


As pointed out by @cormullion, setting the global preferences for the antialiasing quality in the Preferences dialog helps already a lot and allows much larger ImagesSizes.



Now, how to go about setting/resetting the value of HardwareAntialiasingQuality programmatically?



Answer



I've had problems when pushing images above a certain size. For example, it's ok at 1500:


DensityPlot[Sin[x] Sin[y], {x, -4, 4}, {y, -3, 3}, 
  ColorFunction -> "SunsetColors", ImageSize -> 1500]

ok plot


But pushing it too far:


DensityPlot[Sin[x] Sin[y], {x, -4, 4}, {y, -3, 3}, 
  ColorFunction -> "SunsetColors", ImageSize -> 2000]


not ok plot


While I quite like the effect, in an artistic kind of way, clearly Mathematica is reaching into regions of the computer's memory that it shouldn't be. I can see glimpses of other apps, previously opened documents, and so on. (This was a fresh kernel.)


I've had this on versions 8 and 9, and was about to conclude that my computer was going wrong. However, on a hunch, I reset the Antialiasing prefs from Highest down to No Antialiasing, and now the problem doesn't occur very often.


prefs


I must have set it to High for some reason, and forgot that larger images would probably stress it too much.


Your problem may be related!

plotting - How to draw lines between specified dots on ListPlot?

I would like to create a plot where I have unconnected dots and some connected. So far, I have figured out how to draw the dots. My code is the following: ListPlot[{{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4,13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full] I have thought using ListLinePlot command, but I don't know how to specify to the command to draw only selected lines between the dots. Do have any suggestions/hints on how to do that? Thank you. Answer One possibility would be to use Epilog with Line : ListPlot[ {{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4, 13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full, Epilog -> { Line[ ...

equation solving - Invert and fit implicitly defined curve

I need to fit an implicitly defined curve. I thought I could get some data out of Solve , and then using FindFit . Therefore, I would like to find the relation the parametric curve defined by $F(x,y)=0$: Solve[-(1/2) + 1/2 (0.41202 BesselK[0, 0.1 Sqrt[x^2 + y^2]] + (0.101483 x BesselK[1, 0.1 Sqrt[x^2 + y^2]])/Sqrt[x^2 + y^2]) == 0, y] But I can't get an output: Solve was unable to solve the system with inexact coefficients or the system obtained by direct rationalization of inexact numbers present in the system. Since many of the methods used by Solve require exact input, providing Solve with an exact version of the system may help. >> Edit: In particular, I would like to fit the data coming from the curve with the expression of another curve, and not with a function $f(x)$. In particular, since this clearly looks like a cardioid , I would like it to fit to something like it. What other strategies could I try?

dynamic - How can I make a clickable ArrayPlot that returns input?

I would like to create a dynamic ArrayPlot so that the rectangles, when clicked, provide the input. Can I use ArrayPlot for this? Or is there something else I should have to use? Answer ArrayPlot is much more than just a simple array like Grid : it represents a ranged 2D dataset, and its visualization can be finetuned by options like DataReversed and DataRange . These features make it quite complicated to reproduce the same layout and order with Grid . Here I offer AnnotatedArrayPlot which comes in handy when your dataset is more than just a flat 2D array. The dynamic interface allows highlighting individual cells and possibly interacting with them. AnnotatedArrayPlot works the same way as ArrayPlot and accepts the same options plus Enabled , HighlightCoordinates , HighlightStyle and HighlightElementFunction . data = {{Missing["HasSomeMoreData"], GrayLevel[ 1], {RGBColor[0, 1, 1], RGBColor[0, 0, 1], GrayLevel[1]}, RGBColor[0, 1, 0]}, {GrayLevel[0], GrayLevel...
