Welcome to the COLLADA CoherencyTest portal
It is a simple test that check if a COLLADA document is properly composed

Portals:  • Products  • Extensions  • Tools  • Conditioners  • COLLADA DOM  • Coherency Test  • Tech topics  • Tutorials

COLLADA Coherency Test is a command line version of CoherencyTest from COLLADA Refinery. It will check if a Collada dae files is coherent or properly compose. It is build using Collada Dom Library from http://sourceforge.net/projects/collada-dom

It is developed in C/C++ and build using MSVC.

If you have any sugguest of what should go into the coherencytest, please email me at herbert_law@playstation.sony.com

List of Checks

Check_links      -It checks if all id are valid reference and if we 
                 can resolveElement and getElement from a link    
Check_unique_id -It checks if all Ids in each document are unique     
Check_counts	 -It checks number counts are correctly set, eg. 
                 skin vertex count should be = mesh vertex count     
                 accessor has the right count on arrays from stride
                 and counts.
Check_files      -It checks if the image files, cg/fx files, and other
                 non-dae files that the document referenced exist     
Check_textures   -It checks if 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> refernce to <image> id.
Check_URI        -It checks if the URI are correct. It should also 
                 check for unescaped spaces because a xml validator 
                 won't catch the problem. Reference 
                 http://www.w3.org/TR/xmlschema-2/#anyURI
Check_schema     -It checks if the document validates against the Schema   
Check_inputs     -It checks if the required number of input elements 
                 are present and that they have the correct semantic 
                 values for their sources.   
Check_skin       -It will check if values in name_array should only 
                 reference to an existing SID, and values in 
                 IDREF_array should only reference to an existing ID  
Check_InstanceGeometry -It checks if all Intance_geometry has 
                 bind_material that has a correct matching 
                 bind_material between symbol and target
Check_Controller -It checks if skin have same number of vertices 
                 weight as the vertices number of geometry. It 
                 checks if morph have same number of vertices 
                 from source geometry as number of vertices in 
                 all other target geometry.
Check_Float_array -It checks if NaN, INF, -INF exist in all the float 
                 array  
Check_sid	  -It checks if a sid is a valid sid   
Check_morph       -It checks if a morph have same number of targets and target_weights
                 -It checks if all targets have the same number of vertices.
