Java3D vs IDL plotting 3D spheres 2163 1
Started by Deleted User
I have just started programming in IDL. Before, I have written a tool in Java (using Java3D) that links an image to a 3D plot, representing feature space. Pixels are visualized as small spheres in the 3D plot and a user can rotate the plot and interactively select these small spheres. I was wondering whether thousands of small spheres can be plotted in a 3D IDL plot and whether this can be done fast and efficiently. My second question relates to interaction and selection in 3D in IDL, ie does ID...

Calling user-written functions with keywords without using CALL_FUNCTION 1823 0
Started by Deleted User
On several occasions, IDL has given me a 'syntax error' when I've tried to run a compiled, user-written function with keywords set. (It does not happen with every user-written function, and no keywords = no problem with the functions that _do_ cause problems.)
It always speicifies the location of the syntax error as the locaton of the '=' in my first 'keyword_n = keyword_n' keyword assignment.
So, while running
IDL> result = my_function(arg_1, arg_2, keyword_1=keyword_1)
gives me ...

question about plot 1783 1
Started by Deleted User
PLOT function is not choosing the last number as the ending point. Like, if last number of Axis X is 437, the range of the graph ends at 500, if it's 2600, it ends at 3000. There are always some empty spaces. I need to put the curve exactly from 0 to the end in the graph area. Is there a way of doing this
thanks

IDL GUI probleme 1739 0

Hello!
I am debutant in IDL GUI creation, and I would like to create a MVC interface graphic.
But I don't know if it's possible with IDL.
Concretely, I want to access to my controler when an event appear.
The problem is, XMANAGER call event procedure itself, and it's impossible to access to my controler in this procedure.
Could you help me and solve my problem.
Thanks in advance.

Layering widgets? 2038 0
Started by Deleted User
Hi,
I have created a widget application that has a widget_tree structure. The tree includes three different types of nodes. Each node type generates a unique event.
I want to show a different compound widget on the right depending on which type of node is selected. I am currently mapping and unmapping them but this doesn't do quite what I want.
My problem is that the nodes, even when unmapped still cannot occupy space on the screen. I want the widgets to replace each other, at the momen...

how to get the subscription of the MEDIAN function's calculating result. 1903 0
Started by Deleted User
I have a three dimension array ,for example image&9150,50,36&93.
idl>midvalue=intarr(50,50,1&93
idl>midvalue&91*,*,0&93=median(image(*,*,0:35),dimension=3)
thus ,I can get the median value in third dimension over all the pixels in the image.but,if i want to know the median value's subscription ,how can I do it
The function of array_indices got a wrong result.I am confused about it.
thanks a lot.

Axis values for using [xyz]tickformat 1967 0
Started by Deleted User
I am comfortable with using &91xyz&93tickformat, even with setting it to a user-defined function. My problem (or at least one way of stating it) is that you can't effectively define such a function, at least not as well as IDL default does, without knowing the axis range, and that doesn't seem to be possible.
IDL default clearly knows the axis range, as an axis range from 0 to 20 is labeled &910,5,10,15,20&93, while a range from 0 to 0.2 is labeled &910.00,0.05,0.10,0.15,0.20&93. The ...

Suppose:

IDL> x=&9110,20,30&93
Why does x&91i&93 yield:

10 20 30 30
While x&913&93 produces the usual error:
