webgl-animometer

The WebGL test case extracted from the Animometer benchmark in the WebKit repository. It has been removed from the overall harness to set the workload at a fixed size.

Running within Chromium

This page is part of Chromium's tough_webgl_cases performance tests. To run that entire benchmark within that repository, assuming you've built Chromium in Release mode and are cd'd into src:

./tools/perf/run_benchmark --browser=release rendering.desktop --story=animometer_webgl > output.txt

The story names include:

animometer_webgl
animometer_webgl_multi_draw
animometer_webgl_indexed
animometer_webgl_indexed_multi_draw
animometer_webgl_indexed_multi_draw_base_vertex_base_instance

Look for the frame_times measurement in particular; that is a good indicator of how quickly and reliably the benchmark ran.

Running locally

Launch an http server at the working directory and navigate the following url in your browser

http://localhost:8080/Animometer/tests/3d/webgl.html

or

http://localhost:8080/Animometer/tests/3d/webgl-indexed-instanced.html

Optional url args:

webgl_version
use_ubos
use_attributes
use_multi_draw

Optional args only for webgl-indexed-instanced:

use_base_vertex_base_instance
num_geometries
draw_list_update_interval

Example:

http://localhost:8080/Animometer/tests/3d/webgl.html?webgl_version=2&use_ubos=1&use_multi_draw=1

Re-recording the WPR

Sometimes it's necessary to re-record the web page replay (WPR) archive in order to run the new version of the test. In this case, update the page set with the new URL, and run:

./tools/perf/record_wpr --upload --browser=system rendering_desktop --story-filter=animometer_webgl

Keeping the gh-pages branch up to date

gh-pages in this repository exactly tracks master. To ensure this, make the following edit to your .git/config (new lines are in bold):

[remote "origin"]
    url = https://github.com/kenrussell/webgl-animometer.git
    fetch = +refs/heads/*:refs/remotes/origin/*
    push = +refs/heads/master:refs/heads/gh-pages
    push = +refs/heads/master:refs/heads/master
