Welcome to the COLLADA CoherencyTest portal
Links to, and information about, a simple test that checks whether 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 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 any suggestions for what should go into the coherency test,please email me at [[mailto: herbert_law@playstation.sony.com|herbert_law@playstation.sony.com]]

List of Checks

Check_links Checks whether all id are valid reference and if we can resolveElement and getElement from a link
Check_unique_id Checks whether all Ids in each document are unique
Check_counts 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.
Check_files Checks whether the image files, cg/fx files, and other non-dae files that the document referenced exist
Check_textures 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> refernce to <image> id.
Check_URI Checks whether URIs 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 Checks whether the document validates against the Schema
Check_inputs Checks whether the required number of input elements are present and that they have the correct semantic values for their sources.
Check_skin Checks that values in name_array reference only to an existing SID, and values in IDREF_array reference only to an existing ID
Check_InstanceGeometry Checks whether all Intance_geometry have bind_material that has a correct matching bind_material between symbol and target
Check_Controller 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.
Check_Float_array Checks whether NaN, INF, INF exist in all the float array
Check_sid Checks whether sids are valid sids
Check_morph
  • Checks whether a morph have same number of targets and target_weights
  • Checks whether all targets have the same number of vertices.
