I am trying to convert an opengl app to a gem object but I am still a bit
confused as to the ortho thing. I
have it pretty much converted but I can only see it using ortho and it looks
very small. This app is made
to be viewed using gluOrtho2D ( 0.0, 1.0, 0.0, 1.0 ); but I cant figure out
Thanks for your responce. perspec -1 640 -1 480 1 1001 did the trick. What I
dont get is why I cant do
perspec -1 640 -1 480 999 1001 and view 0 0 1000. The image disapears I have
to have perspec at
1 1001 to see an image. Even if I do 2 1001 I get nothing. With other geos it
works but not
The reason I was not seeing anything was that the code was using glVertex2f and
it seems that
anything above -1 z depth desapears in gem. So I ended up using glVertex3f(
number,number, -1.1)
and now I can see stuff happening. Now my problem is that the action is all
limited to the positive
Ok I tried with a static array like Class array[amount] and it did not
crash, it worked perfect. Now I
have to figure out what I am doing to cause a crash (with heavy cpu load I
persume, still a bit
confused?) using a dynamic array? It would be nice to have a dynamic array so
as not to eat
It doesn't thats whats confusing me. Pixel data is the same on both exept it
takes more cpu to
process. I think it has to do with cpu load but I am not sure. I think I am
going to just try a simple
Class array[amount] intead of Class *pointer = new Class[amount] see if
that would be easier
Jamie,
I am running thru your 2004 apple developer posts.

I am trying to figure out how you solved the carbon windowing issue you had
with Gem for my

I am trying to send some data out of an outlet using a symbol pointer. I have

I am trying to write an external library that uses opencv. I am using os x
10.4.9 and Pd extended 0.3.9.
To display images and movies opencv uses a call to a window. I have a
standalone terminal program
that call the window and displays the image correctly.
When I try to call a window from
Well for never passing pointers around you have some great insight. That did
it. Thanks..
The final outcode for any interested parties:
x-in_frame = (IplImage *)strtol(s-s_name, NULL, 0);
Now I have another snag, but thats in another email.

It seems like the window is made using Carbon. Is there any special way Pd
handles Carbon
windows that would cause this stall? I can also compile opencv to use X11
windowing thru finks gdk.
Would Pd handle that better?

Well it looks like if I get a Gemwin opened first, then I can open an opencv
window without a crash.
Does anyone know what specifically does Gem do to get Pd to open a carbon
window without a
crash?

I am trying to get a external written using functions outside of Pd. I have my
header files included and
the external is compiling but when I try to load it into Pd I get this error:
10): Symbol not found: _whatever-external-function
Expected in: dynamic lookup
[import]: ERROR: can't load
I am trying to get a test compile of the counter example from the how to guide
built in Xcode but I dont
know which target type to choose. When I choose any of the dynamic lib options
I get linker errors like
this:
ld: Undefined symbols:
_class_addbang
_class_new
_gensym
_outlet_float
I am trying to write a set of externals based on the opencv library. My main
interest is in the motion
tracking aspect of opencv. I am new to programing and I am having a tough time
converting the opencv
IplImage data type to the Pd symbol data type in order to send it out of
outlets and in
