Hi everybuddy, i run command in MATLAB like this

!"C:\Program Files\POV-Ray for Windows v3.6\bin\MEGAPOV" +I"E:\Dropbox\POV
ray\2012.07.10\Tree Model_only Leafs_no_shadow08.pov" +O"E:\Dropbox\POV
ray\2012.07.10\a.bmp" +L"C:\Program Files\POV-Ray for Windows v3.6\include"
+W800 +H600

and it worked and the messages like :

No, that was not the problem, but anyhow you can turn display on

Hi Jaime,

I have got the answer about "null", it seems the megapov rendered the pic in
binary dots,  like the message shows, but the pic still could not be displayed,
i still working on this

ps, the new command is this:

!"C:\Program Files\POV-Ray for Windows v3.6\bin\MEGAPOV"
+I"E:\Dropbox\POV ray\2012.07.10\Tree Model_only Leafs_no_shadow07.pov"
+L"C:\Program Files\POV-Ray for Windows v3.6\include"
+W800 +H600 +D

Aenzo

regards
```

Hi Jaime

I used new code like this :

!"C:\Program Files\POV-Ray for Windows v3.6\bin\MEGAPOV"
+I"E:\Dropbox\POV ray\2012.07.10\Tree Model_only Leafs_no_shadow07.pov"
+L"C:\Program Files\POV-Ray for Windows v3.6\include"
+W800 +H600 +D

and it generated the pic , but could not be displayed, would you see this for
me?

thank you

Regards,

Aenzo

I overlooked this line on the messages from your first post:

...so, it looks like you don't have permission to write on that folder?

That looks like the alternative preview used when there is no graphic
support compiled on the binary... maybe you're using the console version
of MegaPOV? (I don't know if it was compiled with graphic display support)

Ah... I was going to suggest you to try other format next.
