MEL _ Maya API _ comparision video 
Thursday, January 3, 2008, 10:59 AM - Maya.c++.api.
Posted by Administrator
video: video is in real-time.
comparision of relative times consumed by code written in three formats, and performing the same task - a platform specific implementation of Prim's algorithm





left to right in video :
compiled c++ plug-in, MEL script augmented with a C++ plug-in for the hardest part of the code, and entirely MEL script.

In an attempt to 'justify' the spending of learning time , on the C++ API side of things in Maya, we conducted the following test :

1. chose / wrote (using MEL) a processor-intensive algorithm that had minimal geometry creation, . Prim's algorithm proved to be quite handy in this regard: the processor requirements of the algorithm seems to grow quite rapidly with the number of elements.

2. Identified the principal bottleneck within in the algorithm , in regard to execution times. Wrote a c++ Maya plug-in for that part.

3. Transposed the entire algorithm into c++;

The windows in the video above represent the these three steps from right to left.

Details:
a. sample mesh was a 'voronoi' mesh(generated using qhull) of 100 random points.
b. Approx 1300 edges, needing about 850 iterations(for this particular mesh) to find the minimal-spanning-tree.
c. c++ plugin tool took approx 16 seconds to complete the task, the augmented MEl script took Approx 4 minutes and the MEL script completed about 80% of the task in about 8 Minutes.

development time:
MEL : 0.5 days;
Augmented MEL : 0.5 days;
Plug-in : 1.0 days.
(It has to be said that we are in the very early days of learning the Maya API.)

Note : The c++ code inside plug-in(on the right) has a fair amount inefficient structure, in that it uses a large amount of 'string' operations, and duplicates some amount of work between its constituent parts. The MEL script on the other hand, is quite efficient in that it relies almost entirely on MEL commands, and uses only one additional MEL procedure.

More details about the platform specific implementation of the algorithm to be posted soon.
