Our first assignment asked us to draw simple shapes using WebGL. For this particular project I drew a simple square and triangle. Here is a screen shot of my work.

I’m currently taking a computer graphics class and I’ll be spending this semester delving into WebGL. So, I’ll be giving some tutorials as I get new projects to work on.

Setting Up Your Browser To Support WebGL

First do a Google search for “google chrome developer build”, and it should be the first result. Here is the link it took me to.

http://www.google.com/chrome/intl/en/eula_dev.html

Once you have chrome’s developer build, click on [Start->All Programs->Google Chrome] and then right-click on ‘Google Chrome’. Select ‘properties’ and append this to the end of the [Target] string.

--enable-webgl

Here is how my target string looked like.

C:\Users\Chris\AppData\Local\Google\Chrome\Application\chrome.exe --enable-webgl

Now open up Chrome by going through [Start->All Programs->Google Chrome] and you should be ready to view WebGL webpages. Click here to test for your self.
