COLLADA Coherency Test is a command-line version of CoherencyTest from COLLADA Refinery. It checks whether a COLLADA dae file is coherent (properly composed). It is built using the COLLADA DOM library from http://sourceforge.net/projects/collada-dom.
It is developed in C/C++ and built using MSVC.
If you have suggestions for what should go into the coherency test, please email me at email@example.com.
List of Checks
||Checks whether all IDs are valid reference and whether we can resolveElement and getElement from a link
||Checks whether all IDs in each document are unique
||It checks that the number counts are correctly set; for example:
- skin vertex count should be = mesh vertex count
- accessor has the right count on arrays from stride and counts.
||Checks whether the image files, cg/fx files, and other non-dae files that the document reference exist
||Checks whether the textures are correctly defined/used (image, surface, sampler, instancing...) <texture> shouldn't directly reference to <image> ID. It should reference <newparam>'s SID, and have <sampler2D> with <source> reference to another <newparam>'s SID that have <surface> with <init_from> reference to <image> ID.
||Checks whether URIs are correct. It should also check for unescaped spaces because an XML validator won't catch the problem. Reference http://www.w3.org/TR/xmlschema-2/#anyURI
||Checks whether the document validates against the Schema
||Checks whether the required number of input elements are present and that they have the correct semantic values for their sources.
||Checks that values in name_array reference only to an existing SID, and values in IDREF_array reference only to an existing ID
||Checks whether all Instance_geometry have bind_material that has a correct matching bind_material between symbol and target
||Checks whether skin have same number of vertices weight as the vertices number of geometry. It checks whether morph has the same number of vertices from source geometry as number of vertices in all other target geometry.
||Checks whether NaN, INF, INF exist in all the float array
||Checks whether SIDs are valid SIDs
- Checks whether a morph has the same number of targets and target_weights.
- Checks whether all targets have the same number of vertices.
Usage: coherencytest filename.dae ... [OPTION]...
filename.dae - check collada file filename.dae,
filename.dae should be a url format
-log filename.log - log warnings and errors in filename.log
-check SCHEMA COUNTS .. - check SCHEMA and COUNTS only, test all
if not specify any
-ignore SCHEMA COUNTS .. - ignore SCHEMA and COUNTS only, test all
if not specify any
-quiet -q - disable printfs and MessageBox
-version - print version and copyright information
-xmlschema schema.xsd - use your own version of schema.xsd to do schema check
- the defualt schema is http://www.collada.org/2005/11/COLLADASchema.xsd
