Structure

I have isolated a strange bug under Lion using QB 1.2.

Generating a structure works in QC editor 4 / 4.5 and QB 1.2 under Snow Leopard, but does nothing when compiled with QB 1.2 under Lion.

Can anyone confirm this?

I could not manage to generate structures through javascript either, something invisible happens along the way.

after a brief study how to nest iterators seen @noboko (thanks @gtoledo3 for useful link! http://kineme.net/forum/DevelopingCompositions/SuperCoolQuartzComposerQtzs) i tried to hook them to make structures. few examples attached.

so far i had an interesting adventure in generating various combinations of lines and stuff.. but i'm really stuck at this point. i have a basic question:

does this kind of structuring makes sense? could it go further (lets say something like http://kineme.net/Release/Beta/GLLookVeryCool) ?

is there a way to make offsetting points more controllable by this method, or i should include any other tools, maybe i'm missing something about structure making in general?

any tip would be appreciated!

Hi to all, I'm trying to extend my iniTree plugin with a custom plugin that outputs a structure with vertices position every frame, as suggested by gToledo. To try this kind of output I tried to modify my drawTest plugin so instead of render vertices it outputs vertices position.. but I cannot make it work properly. This is my approach:

• vertices positions are stored in a float vector

float   v[VSIZE][3];

• vertices positions are copied every frame in a NSArray (output_struct) made of NSArrays (currVertex) in this way:

   for(int x=0;x<numV;x++){
      [currVertex removeAllObjects];
      [currVertex addObject:[NSNumber numberWithFloat:v[x][0]]];
      [currVertex addObject:[NSNumber numberWithFloat:v[x][1]]];
      [currVertex addObject:[NSNumber numberWithFloat:v[x][2]]];
      [currVertex addObject:[NSNumber numberWithFloat:1.0]];
      [outputVertices addObject:currVertex];
   }
 
      //create output structure
   self.output_struct = [NSArray arrayWithArray:outputVertices];

It seems to output the same kind of result of a mesh importer (you can see it in outputs img), but for some reason my plugin output doesn't work. In the zip you can find xcode project, a composition example and a dae mesh to test it.

I think I don't build the structure in the correct way. For example, in the Apple developer guide I read that we must use NSDictionary to output a structure, but I can't use it in the correct way. Anyone knows the correct way to output a structure from a custom plugin?

Hi,

Does anyone know how to create a slideshow using an image index like this one?
