Vince, I had the same question a few months ago.
I cobbled this together:
cameraCoords.rb
You can also look at the code for CameraKeyMaker. I've never used it, but from looking at the code it implements a lot of features that you might be looking for.

No, I didn't test it with the Developer Console. I was thinking the people who would most want to profile their code would have such a huge trace that they would want to dump to a file. Maybe printing to stdout should have an option of showing the top N entries...
I posted a new version (see original post for files to download). Recent changes:
` %(#00BF00)[# Rev. | .Date..... | Notes
The enhancement in v0.98 lets you calculate the daylight factor as a ratio of observed weather to clear sky (Bird-Hulstrum model). So for example, this is the clear sky expectation over the course of a year for some geometry geolocated in Seattle, Washington (note the max daylight factor appearing in the bottom left corner area):
Using a weather file from Seattle, the daylight factor looked like this:
In other words, over a typical year the cloud cover allows only 78% of the theoretical maximum sunlight reaching a horizontal surface.
Contrast that with the same geometry geolocated to Phoenix, Arizona. This is the daylight factor using the Phoenix TMY3 weather file. Very little cloud cover.
In TMY3 mode (a.k.a weather file), I could also have displayed the results in terms of watts per square meter, to get an idea of the amount of solar energy I could capture with a photovoltaic array. Note, however, that you would have to factor in PV efficiency (or inefficiency).
It should also be noted that the computations currently take a while. The above test uses really simple geometry. Here is what is being calculated:
Hence the need for this plugin:

So... here is a SketchUp plugin that does basic profiling of each function call. It is modified from the stock profiler.rb that came with Ruby 1.8.7 (see https://github.com/ruby/ruby/blob/ruby_1_8_7/lib/profiler.rb). A good writeup of profiler.rb is found here: http://www.ibm.com/developerworks/opensource/tutorials/os-ruby2/section3.html
Usage

The output will be something like this:

Example usage:
[profiler_test.rb](/uploads/imported_attachments/Q1CQ_profiler_test.rb)Thanks for the feedback and for bearing with me. First SketchUp plugin (and first time coding in Ruby, for that matter! My background is C/C++, Perl and PHP).
I've updated the original post with the new code.
Daylight analysis using SketchUp has been more or less an interactive affair (turn on shadows, move the sliders, observe the light patterns), or it has required knowledge of external programs (Ecotect, Daysim, Radiance, etc.).
This plugin calculates the amount of sunlight (insolation) falling on a group of faces over the course of a year, relative to the max sunlight theoretically available under a clear sky with no shade structures. The result is the daylight factor -- a number between 0.00 (completely shaded all year long) and 1.00 (nothing blocking the sun). The plugin color-codes and labels the target faces to indicate their daylight factor.
(model by Mugur)
Basic mode:
Advanced mode:
Feature summary:
Sun positions are calculated for each hour, based on latitude and longitude
Calculates direct beam and diffuse irradiation (accounts for atmospheric scattering and ground-based reflectance)
Output can be written to a comma-separated file
Output can be in terms of solar irradiation (in watts per meter squared)
Shading structures selected by layer
Glass or semi-transparent faces selected by layer (user-input transmissivity)
Future enhancements:
Ability to specify TMY3 weather file for solar insolation actually observed in v0.98
Optimize computation time
Some code was translated from other people’s work. Please see credits, plugin options, and more details in the documentation (updated 2013-08-11)
