I ran into a problem trying to load a .ASC file. I found out that it was because the parser had a problem trying to determine the contents of an .ASC file. For ...

Moving to 0.7 to make way for higher priority tickets.

We currently have xbps.js and psapi.js files in the repository. One is the actual library, the other is a JS file which includes other necessary js files. These...

Marking this ticket as blocked by Opera.

We should add the SMS demo to the repository

I played with anti-aliasing on Chrome and found that the performance hit is ~10 fps.

On my macbook pro:

Chrome: ~42fps with AA ~51fps without AA
Minefield: ~65f...

I filed a bug with Opera. I found Firefox, Chrome and Safari call onreadystatechange 200-300 times for a 10MB over a network, while Opera only calls it 3 times,...

When using the prerelease Opera on Windows, it waits for the entire point cloud to be downloaded and parsed before rendering anything.

This is likely an issue w...

This is no longer an issue, I think it was Benoit who fixed it.

I had to add a bit of a hack to get it to render properly on an nVidia card.

I managed to get Sundae.js working with XB PointStream. I wrote a blog about it here: http://asalga.wordpress.com/2011/03/02/hacking-sundae-js/

Branch: http://g...

Carl just released 0.5 of sundae.js, I'm going to see about integrating it into our framework.

The library expects all vertex data from the parsers to in synch. That is, it expects to be fed the same number of vertices as normals and colors. If 100 vertic...

Looks like Chrome is using anti-aliasing and Minefield isn't. I'll look into this.

Also, I wonder if this is related to the frame rate. I'll try toggling anti-a...

See image below.

Chrome appears to be doing some king of image processing or other rendering process that provides a nicer image but with lower frame rates.

With the canvas open and the cloud loaded the mouse events are not contained within the canvas.

If you mouse down on the canvas and move outside to the page the...

We should update the library interface to allow users to instantiate and use the library in a more JavaScript-style way.

var ps;

function start(){
  var ps = ...

When useProgram() is called, the pointSize function needs to be called. Users shouldn't need to set the point size every time a program is changed.

We need a demo which streams and renders the same point cloud which uses different fidelity levels. Possibly loading different levels of detail depending on the...

createProgram is returning a WebGLProgramObject. We should abstract this return type.

We have a number of demos which use shaders which have been defined in strings. We can safely move these shaders to script tags instead. They will be easier to ...

On OSX 10.6, some shaders are having issues with coloring.

Here is my first draft on how to create a parser:
