    <p>I would like to render an animated voxel scene using WebGL and Three.js, for a hobby project (to visualize live point cloud data from a server-side stream).</p> <p>the scene is not very huge - it should be around 128*128*128 voxels (2 millions points).</p> <p>So I suppose I could just load a big static file containing all voxels data, then incrementally add or delete individual voxels, depending on events in a stream from a server. </p> <p>However after seeing this demo (which is not based on a volume (with "inner" details) but a simpler "XY coordinates + elevation + time" model) :</p> <p><a href="http://mrdoob.github.com/three.js/examples/webgl_kinect.html" rel="nofollow">webgl kinect demo</a></p> <p>I am wondering:</p> <p><strong>Could I use the same things (video, textures, shaders..) to render my voxel animations? How would you implement this?</strong></p> <p>I don't have that much "hobby time" so I prefer to ask out before :) For the moment I am thinking about loading many videos, for each layer of the voxel model.</p> <p>But I'm not sure that three.js will like it. On the other hand, voxels are always big memory consumers so maybe I don't have a lot of choices..</p> <p>Thank you</p> <hr> <p>Update 1:</p> <p>I do not need, indeed, real-time visualization of the data. I could just poll the server once in a while (downloading a new snapshot as soon as the previous has been loaded on the GPU)!</p> <hr> <p>Update 2:</p> <p>Each voxel has a material attached to it (the "color")</p>

    1. COHow often do you like to update your data and does the format of the data matter to you?

    2. COthank you for your interest in my issue! The format does not really matter. I suppose this is a matter of balance between the update frequency and the volume of data. I do not need a realtime update, one every couple of seconds would be already great (the goal is to monitor an algorithm which work on the point cloud / voxel model. So I want to see what is happening, but I do not really need to see every steps, or even so, definitely not in realtime)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
