Matthias Möller committed Oct 26, 2012 17 The \ref incremental provides the best quality, while  Jan Möbius committed Nov 07, 2012 18 the \ref multiple_choice is the fastest one.  Matthias Möller committed Oct 26, 2012 19 20 21 22 23 Now, you can choose your constraints and the decimation order. Don't forget to define stop conditions. If done, press Initialize and then Decimate. After pressing "Initialize" or Decimate, it is possible to  Jan Möbius committed Oct 26, 2012 24 25 26 27 28 change the constraint values and decimate again having the original error quadrics of your mesh. Otherwise, by adding or removing constraints, you have to reinitialize the decimater. This will update the error quadrics, so the next decimation will be based on the errors to the current mesh, and not the original mesh.  Jan Möbius committed Nov 07, 2012 29 Also, changing the \ref decimaters, or the Decimation Order, will  Jan Möbius committed Oct 26, 2012 30 cause a re-initialization.  Matthias Möller committed Oct 26, 2012 31 32 33 34 35 36 37  \note The Initialization saves the error quadric of each vertex. They will not be updated, until Initialize is pressed again.

So, this decimater is the first choice for best optimal results, but might be slow.  Matthias Möller committed Oct 26, 2012 44 45 46 47 Use \ref multiple_choice or \ref mixed to get faster, but less accurate results. \subsection multiple_choice Multiple Choice Decimater  Jan Möbius committed Nov 07, 2012 48 The multiple choice decimater checks Nuber of Random Samples and takes the best one for the next collapse.  Jan Möbius committed Oct 26, 2012 49 As there is no heap involved, this is usually faster than the incremental approach but as it is randomized,  Matthias Möller committed Oct 26, 2012 50 51 52 53 the result is not guarantied to be the best, but still inside the specified constraints. \subsection mixed Mixed Decimater  Jan Möbius committed Oct 26, 2012 54 55 Uses Multiple Choice Decimater and Incremental Decimater to get as good and fast results as possible. This decimater uses several steps of the Multiple Choice Decimater with decreasing constraint threshold.  Matthias Möller committed Oct 26, 2012 56 57 58 When 80% of the maximal error are reached or 80% of the collapses have been performed, it switches back to the Incremental Decimater to do the rest. */
