2015.03.17

features

  • Update file format to 1.6. (see Potree File Format )
  • Removed hierarchy from cloud.js and store it in smaller chunks.
  • Node-files in ./data are now grouped into a directory hierarchy.
  • RGB, INTENSITY and CLASSIFICATION can be written to the binary format in any order and combination.
  • Added EarthControls. This navigation mode provides faster and more precise navigation in large but flat 3d models such as landscapes from LIDAR data.
  • Point picking and height profile queries return all available point attributes, instead of positions only. (see potree#124)
  • Height profile queries return a project() helper function that unrolls the queried points along the x-axis. Can be used to draw 2D height profile images. (see potree#124)
  • Added an angle measurement tool. (Thanks to @Maartenvm )

changes

  • Update to three.js r70.
  • Load bin files in a WebWorker to take off work from the main thread.

bugfixes

  • Lots of bugfixes, most importantly regarding point picking and canvas resizing.

2014.30.12

features

  • Rebuild the profile tool to behave more like the distant measure tool. Visible points inside the profile can be retrieved with
var points = pointcloud.getPointsInProfile(profileTool.profiles[0], maxOctreeDepth);
  • Added clip modes: DISABLED, CLIP_OUTSIDE, HIGHLIGHT_INSIDE. Clip mode can be set with
pointcloud.material.clipMode = Potree.ClipMode.CLIP_OUTSIDE;

  • Added support for potree format 1.4. This format stores coordinates as integers instead of floats (for uniform precision). Additionaly, the .bin extension has been added to all data/ files in order to avoid problems that occur with files witout extensions.

  • Added High Quality Splatting for screen aligned quads. See examples/viewer.html with quality set to "Splats".

2014.12.17

features

  • Added Area and Volume measurement tools.

  • Made tool markers draggable.

  • See examples/viewer.js for a demo of all measurement tools. In this demo, the volume can be translated, scaled and rotated by pressing e, r and t.

  • Attenuated point sizes are differently scaled. Now, the point size specifies the radius of the point in scene coordinates.

  • Adaptive point sizes are differently scaled. A size of 1 means that the point size is choosen to optimaly cover holes. Due to this it is now necessary to pass the renderer to the pointcloud.update() function:

    pointcloud.update(camera, renderer);

bugfixes

  • LAS and LAZ format now support point picking, too.
  • Using mediump precision instead of highp. Highp is not supported on all devices and it seems like it's generaly adviced not to use it.

2014.12.03

  • Made measurement tool independant of scale. Spheres and Labels are displayed at the same size regardless of the distance to the camera. MeasurementTool now has to be rendered using

    // render scene first, then measuring tool over the scene
renderer.render(scene, camera);
measuringTool.render();

  • Support for binary files with .bin extension. Files without extension have shown to cause problems with FTP Uploaders and some WebServers.

  • Added classification, return number and point source ID to Potree.PointColorType. These color modes only work with LAS and LAZ files.

  • Replaced synchronous requests in favour of async requests. You must now provide a callback method in order to add a pointcloud to the scene:

    var pco = POCLoader.load(pointcloudPath, function(geometry){
	pointcloud = new Potree.PointCloudOctree(geometry);
	...
  scene.add(pointcloud);
});

    You must also make sure that the pointcloud has been loaded before operating on it:

    if(pointcloud){
	// now you can safely use the pointcloud object
}
