改编自BrandonJones基准测试httpsglmatrix.googlecode.comhg.zip

Simple benchmarks for testing the speed of JavaScript matrix libraries adapted from Brandon Jones benchmarks in his glmatrix library: https://glmatrix.googlecode.com/hg/ If you have a browser with WebGL you can run the benchmarks [here](http://stepheneb.github.com/webgl-matrix-benchmarks/matrix_benchmark.html). This work is based on Brandon's work as of this commit: e5ad8f6975eef038de668914a44ed36e2c611966 Date: October 10, 2010 12:49:00 PM EDT Upped version to 0.9.5 Comparing these matrix libraries: * [glMatrix](http://code.google.com/p/glmatrix), [zlib license](http://www.opensource.org/licenses/Zlib) * [mjs](http://code.google.com/p/webgl-mjs), [MIT license](http://www.opensource.org/licenses/mit-license.php) * CanvasMatrix * [EWGL_math](http://code.google.com/p/ewgl-matrices), [New BSD license](http://www.opensource.org/licenses/bsd-license.php) * [tdl](http://code.google.com/p/threedlibrary/), [New BSD license](http://www.opensource.org/licenses/bsd-license.php) * [Closure](http://closure-library.googlecode.com/), [Apache 2.0](http://www.apache.org/licenses/LICENSE-2.0) * [Sylvester](http://sylvester.jcoglan.com/), [MIT license](http://www.opensource.org/licenses/mit-license.php) Changes from Brandon's original benchmark code include: * Only including the benchmark code from glmatrix. * Updated to the latest mjs as of Dec 15: 16:8e5b0944ef1e and included it in several more tests. * Added a graph display of the results using flotr, see: http://solutoire.com/flotr/ * Added tdl library (thanks to Gregg Tavares) * each library runs in an iframe so the code won't affect the other libraries (thanks to Gregg Tavares) * Added Sylvester library (thanks to [Felix E. Klee](mailto:felix.klee@inka.de)) Brandon's original code was released under the [New BSD license](http://www.opensource.org/licenses/bsd-license.php). My additions to the benchmarking code are released under the same license. ## Running locally requires a web server. With the recent changes by Gregg Tavares that run each library in an iFrame you will need to either: * Run the benchmarks from a local web server * Configure the browser to allow local file access ### Configuring Chrome to allow local file access On Windows you can add a flag in the shortcut. On Mac OS X start Chrome from the command line like this: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --allow-file-access-from-files ### Using Python's SimpleHTTPServer cd /path/to/webgl-matrix-benchmarks python -m SimpleHTTPServer Now open: <http://localhost:8000/matrix_benchmark.html> ### Set up an webgl-matrix-benchmarks.local local host and Apache vhost on Mac OS X On OS X, turn on Web Sharing via (Apple Menu) -> System Preferences -> Sharing -> Web Sharing Now, make sure that virtual hosting is enabled by editing `/private/etc/apache2/httpd.conf` and uncommenting the virtual hosting line (at about line 465 of the stock `httpd.conf`) as follows: # Virtual hosts Include /private/etc/apache2/extra/httpd-vhosts.conf At the top of httpd-vhosts.conf enable name-based virtual hosts for port 80 on all interfaces: NameVirtualHost *:80 Edit the virtual hosting configuration file `/private/etc/apache2/extra/httpd-vhosts.conf` to include the entry: <VirtualHost webgl-matrix-benchmarks.local:80> ServerName webgl-matrix-benchmarks DocumentRoot /path/to/webgl-matrix-benchmarks PassengerEnabled off <Directory /path/to/webgl-matrix-benchmarks > Options +Indexes +FollowSymLinks +MultiViews +Includes AllowOverride All Order allow,deny Allow from all DirectoryIndex matrix_benchmark.html </Directory> </VirtualHost> after making changes test the config: `apachectl configtest` When the configuration syntax is correct restart apache: `sudo apachectl restart` If there are issues try tailing the general apache2 error log: `tail -n 200 -f /var/log/apache2/error_log` For more instructions, set <http://shapeshed.com/journal/setting_up_local_websites_on_snow_leopard/>. And, finally, edit your `/etc/hosts` file to include the following line: 127.0.0.1 webgl-matrix-benchmarks.local Confirm that the new entry works: $ dscacheutil -q host -a name webgl-matrix-benchmarks.local name: webgl-matrix-benchmarks.local ip_address: 127.0.0.1 It might be necessary to flush the local DNS cache: $ sudo dscacheutil -flushcache Now open: <http://webgl-matrix-benchmarks.local/>
