It has since been systematically reconstituted to a degree that bears little resemblance to the original code, but retains backward compatibility with it. This work was done in the public domain, for all. It is a good question as to whether or not the original copyright claims pertain still, but it is not of importance, and the library remains inspired by the workings of the original and indebted to and continually interested in its legacy.
This page is a one page user guide to the new library. It's hoped that one page suffices. But before getting into code examples, a short explanation of some of the terminology and predicaments entailed:. It failed to catch on. Its afterimage is in the form of various import and export plug-in utilities for various software. Version 2. It further expands the mission of COLLADA by imagining it as a future standard 3-D model format--a role that many take for granted, being unaware of subtle distinctions in terms of the designers original intent.
It puts forward that this role, as a storage format, is more important in the coming years, especially as it concerns noncommercial applications. Yet in retrospect, it actually establishes a very high bar for software development. Indeed, one that it is impractical to take lightly. For this reason, it seems as if developers could use a good amount of assistance. The new library approaches this in two ways: The first is simply to offer features that had been missing, which no XML document is complete without.
And in addition to this there is an even greater need for a symbolic expressiveness that owes much to the need to reserve the use of language identifiers to the schemas themselves. The reason this is required now is so to establish a long sought after all encompassing lingua franca for 3-D model data digital artifacts in order to prepare a path to a modern 3-D era at home in the noncommercial sphere.
This basic notion it refers to as "cyberspace:" a term that's long been misapplied only to defy the ability to formulate a working model, or to relabel things which already exist and as such have no import. To this end it must be a platonic space of works of art, and not a "place" as often conceived, like the WWW or Internet, or not a landscape in new clothes, but rather a platonic space of digital artifacts.
At this moment there is no noncommercial storage format if one is required. That is less grandiose than "cyberspace" but no less important, and in fact it is a natural predecessor to a cyberspace century. In order to speak meaningfully in this language there must be an ecosystem of applications wherein each must be able to faithfully transform the language, even if it cannot or does not need to comprehend it. If this basic end is not met then it is as if there is a legendary Tower of Babel where all is lost in translation.
This is the first order of business. Without the software means, then what good is another standard? This is the more important work. This is the work of our day. The first thing that is different about version 2. The " dae " prefix is retained by low-level APIs. The new generator offers two flavors: 2 and 3.
There are some reserved second-level namespaces, however when an XML Schema is added by a include directive, a second-level namespace is created for it. This makes the identifiers shorter, which can make printouts and pop-up titles easier to read. The macro adds the longer name as an alias. The generator cannot know the short name, and so depends on the alias.
Just include the whole thing, it's not much of a thing. It controls the linkage of the metadata registration routines. If blank the routines will have external linkage, or default linkage.
If it is inline then inline linkage is used. This can affect the compiler's performance and the sizes of the outputted object-files. When external linkage is used, it is necessary to control which translation-unit contains the definitions.
If it is defined, the definitions are not included in the current translation unit. Its inclusion has the side-effect of recursively including the rest of the schema.
The include-guards should just be copied from the generator output. This is not how include-guards are traditionally used. In fact, by defining them ahead of the recursive inclusion operation, the effect is to exclude.
Note that this page is a Quick Start Guide only. After a project is up and running, it's possible to begin exploring the further ins-and-outs of the core library directly and by example. Working with user-generated schemas across static libraries can present unique challenges.
Blender does a best effort on importing lights from a dae-file. If a Blender profile is detected for lights, all values from these will be used instead. This ensures full re-import from a Blender exported dae-file. The entire Light struct from Blender will be exported through this profile, with the exception of light curve falloff.
Support for object mesh, camera, light transform animations. Only Euler rotations, which is the default option for Objects, can be exported. For armature bone animations, Euler and quaternion rotation types are supported. Fully rigified armature animations referring to the Rigify add-on. For export of rigified armature animations:. Select Bake Action. If you have only the deform bones selected check Only Selected.
This will give smaller dae. Otherwise uncheck Only Selected. Select the mesh and the deform bones. Then export to Collada while checking only selected option. Selecting only the Mesh and bones is not strictly necessary. Selecting and export only selected will give smaller dae. Demonstration video. To correctly derive the bone-to-tail location on re-import. Blender 3. Second Life Rigged — is good for exporting the SL default character.
All other export settings will not work for Second Life. The character orientation needs to be such that the character looks towards positive X. Scale and Rotation must be applied before the export! Hint You can select only an armature, then using this option, all rigged meshes attached to the armature will also be exported.
Hint You can select only the objects, then in the exporter enable this option to export the armature data also. Note Important Things to Remember Object and data-block names are constrained to 21 characters bytes. UV layer names are constrained to 32 characters bytes. The link warning should be gone and your application should run fine. For the domTest program you also need the Boost Filesystem library installed. These libraries are fairly popular and it's expected that most Linux distributions will provide them via the package manager, so these libraries aren't provided with the Linux DOM as they are for Windows and Mac.
For example, in Ubuntu you could install these libraries using aptitude:. On Linux, the DOM builds as both a static lib. This builds a release version of the DOM. Important: make version 3.
If you have a file named test. NOTE: you may need to add -lcollada14dom after specifying where the libraries are with -L. The make install rule also takes a 'prefix' argument that allows you to specify where to install to.
See the make readme for more info. The main benefit of this is that you can make sure that the DOM shared lib is in your PATH, so you can easily run a program that links against the shared lib.
Note: The only officially supported version of OS X is The Mac uses the same make build architecture as Linux and PS3.
