VTK:Improvement

Documentation Improvement

(If you agree with the following, vote for the improvements!!)

In my experience, the single most important factor that influences a users attitude about a software package is its ease of use. VTK provides a phenomenal collection of tools for scientific data processing and visualization. However, if a user has difficulty accessing these tools, their experience with, and therefore opinion of, the software will be less than satisfactory. Documentation is the key element which controls this difficulty level. I propose some improvements to the documentation system here.

General

• Add required libraries list to each class
• Clearly indicate default values
• Clearly explain all function parameters

vtkKdTree

• SetNumberOfRegionsOrLess has no documentation.
• SetNumberOfRegionsOrMore has no documentation.
• SetFudgeFactor should not be a function because the fudge factor is always computed in the BuildLocator or BuildLocatorFromPoints function

vtkLandmarkTransform

• SetTargetLandmarks/SetSourceLandmarks - both of these have the same description. One should talk about the target only and the other should talk about the source only.
• GetSource/TargetLandmarks - same description as the Set* methods. This is incorrect.
• SetModeToRigidBody has the same desciption as SetSourceLandmarks. This is incorrect.
• SetModeTo* has the same description as SetSourceLandmarks. This is incorrect.
• GetMTime - says "Get the MTime". What is MTime? Modification time? Maybe "Get the time at which the object was last modified."

vtkDecimatePro

Add this:

The SetTargetReduction function specifies how many triangles should reduced by specifying the percentage ([0,1]) of triangles to be removed. For example, if the mesh contains 100 triangles and SetTargetReduction(.90) is called, after the decimation there will be approximately 10 triangles - a 90% reduction.
