polygon disappears when performing boolean > union

#21

ok - here’s the latest set of errors with polyhedron_impl.hpp having this as line 119:

const face_t *f = edge_faces[i];

and 134:

const face_t *f = vertex_faces[i];

and I’m still using boost

Now we stumble upon the most controversial subject between compilers, namely templates. In the lines of the first two error, please delete the keyword typename.

BTW, which compiler do you use, and are there other compilers out there?

#23

I’m using clang, which is the default compiler in OS X 10.8 but I can probably set it to fall back to gcc, if you can tell me how to change that

#24

The compiler is right, data_t isn’t not a member of the outside class, but a template parameter. Please change in lines 241, 269 the kd_node::data_t to data_t.
If it continues complaining about the same lines, then please change it instead to typename data_t (maybe now, without the kd_node, it would except the typename keyword, although it’s not that necessary to use it here).

I suggest that you try in parallel to compile with gcc as well in a different directory. In order to do so, copy only the original files, or more specifically the whole directory without the directory that cmake created. Actually I think if you specify for cmake a different “where to build the binaries” it should be enough. It would start the configuration from scratch and you could choose from a combo box the compiler you want to work with. But using a different directory for the source files as well would be wise, so the changes that we make to the source files won’t collide between the two compilers.

#25

I think we have a success now. Clean exit only one small warning:

so, where do we go from here? Is this ready to send off to my friend who does the plug-in building?

#26

I suppose. Do I remember correctly that you have many OSs with all maya versions, and you can build a plugin to almost any maya version on any platform, or am I confusing you with someone else?

The warning points to something that definitely looks like a bug. Which value is returned for the function if the ‘if’ isn’t satisfied? From the usage of the function I propose the following solution: To the end of line 166 in csg_triangulator.hpp please add (again, not in a new line, so we would preserve the line numbers for the rest of the source code):

else return 0;

or just

return 0;
#27

Hi,

I was able to build carve with xcode on Mac, after changing everything as described. No I’m trying to build the Boolop and BoolPro sources. First thing to mention is, that you have to change the include “conio.h” to “curses.h” in “main.cpp” of Boolop. According to that you also have to add “/usr/lib/libncurses.dylib” to the Library search Paths.

As Im a complete noob with C++ I’m totally stuck right now. To build the sources I added all Maya Headers and Libraries. Additionally I added the Carve includes to the Header search Paths. My Problem is, that I’m getting new errors trying to build Carve in this context. Do I need to include the already build “libcarve.dylib” or something? Or is it required to be able to build carve in the Maya plugin context?

Here are the new Errors with Apple LLVM compiler 4.2:

Would be very nice to compile that one for Mac as well!

#28

http://code.google.com/p/carve/

#29

@cgbeige, he doesn’t really need to build the plugin, but only requires the binary; can you help him there?

@sit10, as I mentioned, your compilation was successful, but the linkage failed, and it missing carve lib symbols. So yes, you need to include libcarve.dylib (add it as an input lib). Also, did you build carve lib and the plugin with the same compiler using the same compiler flags?

#30

@zoharl and @cgbeige After two days of compiler built setting testing, I found out that I only had to remove “OpenMayaMac.h” from the prefix header. I was not able to use the already build “libcarve.dylib” I had to compile the whole carve lib together with the BoolPro source files. I’m pretty sure I just don’t know how to link the .dylib file right. I was now able to build BoolPro for Maya 2012 and 2013 for mac. It’s a real enrichment to Maya. Thank you for that!

Unfortunately I wasn’t able to to build Boolop so far. I used the exact same Environment I was able to build BoolPro, but as far I’m trying to build main.cpp from the boolop sources I get these Errors:

What do you need boolop for? It is obsolete, i.e. superseded by boolPro. If you have the boolPro plugin, then use the python setup script to connect the nodes, and you are ready to go.

Also if you have the plugin binaries that other people can use for OSX, please consider sending them to me (zoharl3@yahoo.com), so I would add them to boolPro download page, so other people could take advantage of it.

Yes you are right. I’ll send them to you! I have two questions:

  1. Is it possible to add an Python shelf button that will create a boolPro Node that has another Bool Type at creation. Because If you have quite complex meshes you have to wait long until you’ll be able to change the Bool Type in the node.
  2. Thats maybe a dumb question, but how do I add a Mesh with the “Add New Item”? It alwas adds the boolPro node which ich obviously selected to be able to click the “Add new Item” Button :curious:

Thanks for the plugins.

    I'll answer both questions. Instead of using the python setup script, setup everything yourself manually. You can do everything through maya GUI (e.g. connection editor), or you can create two shelf buttons, one for creating the boolPro node, and one for adding an object. This tutorial should work for maya's inner boolean command as well.
    
    1. Make sure the plugin is loaded:

if not mel.eval('exists boolPro'): 		
      	mc.loadPlugin('boolPro')

    or use plugin manager.
    2. Create a boolPro node and an output mesh.

res = mc.createNode("mesh")
       mc.sets(res, add="initialShadingGroup")
        bpro = mc.createNode('boolPro');
        mc.connectAttr('%s.outputMesh'%bpro, '%s.inMesh'%res,f=1)

    3. Change in the boolPro node the attributes you want, e.g. change the operation from union to intersection.
    4. Connect new objects to the boolPro node. For example, to add 'cube1' to 'boolPro1':
    First add a new item slot for the new object:

mel.eval('source AEnewNonNumericMulti.mel;  AEnewNonNumericMultiAddNewItem("boolPro1","inputMesh");')
        

    or use the 'Add new item' button in the attribute editor of the plugin, and then connect the new object to that slot (slot0 in this case, designated by [0]).

        mc.connectAttr('pCube1.worldMesh', 'boolPro1.inputMesh[0]',f=1)

    or use the connection editor/hypershade.
