Learn WebGL with Dart

dart-webgl

Learn WebGL with Dart!

The is my re-write of learningwebgl.com 16 lessons to the Dart programing language. It is by no means perfect, however I try to leverage the language and its features to introduce structure earlier in the lessons. My hope is this will get more people interested in WebGL programming that might not have been before, while also showing off some of what Dart can do.

Each lesson is fully loaded when compiled. The user need only selected which lesson to run from a drop down box. Optional URL parameters include:

lsn=(1-16) - The default lesson number to show.
width=x    - The width of the canvas element.
height=x   - The height of the canvas element.
fps        - Display a running average frame rate.

Future rewrites of the original articles covering these changes are to coming!

dart-webgl's Issues

In infinite animation loop why use window.requestAnimationFrame and not Future animationFrame

Is there a reason you chose the callback version over animation frame over getting a Future animationframe and animationframe.then((content) => tick())?

Great work. This is exactly what I was looking for.

pub serve generates 404

Hi! I cloned the repository, moved into created directory and run "pub serve".
After I opened http://localhost:8080/ it generated:

404 Not Found
Could not find asset web in package learn_gl.

If it's not the right way to run this project, please describe the correct way in the README.md ... and if it's the correct way, please fix it :-)

Thanks!

P.S.: Console output:

bash-3.2$ pub serve
Loading source assets... 
Serving learn_gl web on http://localhost:8080
Build completed successfully
[web] GET / → Could not find asset learn_gl|web.

Still working on this?

Hey!

Are you still working on this?

Thanks.

Example 4 crashes on startup in checked mode

Using latest dart sdk: 0.6.9.2_r25388

When launching the application in dartium, selecting example 4 from the drop down box results in an error:

"Breaking on exception: type 'List' is not a subtype of type 'List' of 'elements'."
This refers to line 167 in typed_data.dart:
" factory Float32List.fromList(List < double > elements) {"

Running the application in production mode does not reveal the problem.
