我稍微更改了演示 #11 以加载我的图像而不是演示。
我可以很好地加载我的 MRI 图像,请参阅演示。如果我将我的标签映射加载为主卷,它也可以工作。
window.onload = function() {
// create and initialize a 3D renderer
var r = new X.renderer3D();
r.init();
// create a X.volume
var volume = new X.volume();
// Attach the single-file dicom in .NRRD format
// this works with gzip/gz/raw encoded NRRD files but XTK also supports other
// formats like MGH/MGZ
volume.file = '1123_N3.nii.gz';
// we also attach a label map to show segmentations on a slice-by-slice base
// volume.labelmap.file = '1123_seg.nii.gz';
// add the volume
r.add(volume);
// the onShowtime method gets executed after all files were fully loaded and just before the first rendering attempt
r.onShowtime = function() {
//
// The GUI panel
//
// (we need to create this during onShowtime(..) since we do not know the
// volume dimensions before the loading was completed)
var gui = new dat.GUI();
// the following configures the gui for interacting with the X.volume
var volumegui = gui.addFolder('Volume');
// now we can configure controllers which switch between slicing and volume rendering
var vrController = volumegui.add(volume, 'volumeRendering');
// configure the volume rendering opacity
var opacityController = volumegui.add(volume, 'opacity', 0, 1).listen();
// and the threshold in the min..max range
var lowerThresholdController = volumegui.add(volume, 'lowerThreshold', volume.min, volume.max);
var upperThresholdController = volumegui.add(volume, 'upperThreshold', volume.min, volume.max);
// the indexX,Y,Z are the currently displayed slice indices in the range [0 - (dimensions-1)]
var sliceXController = volumegui.add(volume, 'indexX', 0, volume.range[0] - 1);
var sliceYController = volumegui.add(volume, 'indexY', 0, volume.range[1] - 1);
var sliceZController = volumegui.add(volume, 'indexZ', 0, volume.range[2] - 1);
volumegui.open();
// and this configures the gui for interacting with the label map overlay
var labelmapgui = gui.addFolder('Label Map');
var labelMapVisibleController = labelmapgui.add(volume.labelmap, 'visible');
var labelMapOpacityController = labelmapgui.add(volume.labelmap, 'opacity', 0, 1);
labelmapgui.open();
};
// adjust the camera position a little bit, just for visualization purposes
r.camera.position = [120, 80, 160];
// showtime! this triggers the loading of the volume and executes r.onShowtime() once done
r.render();
};
但是,如果我将标签映射添加到我的卷中volume.labelmap.file = '1123_seg.nii.gz';
,加载失败并且卷永远不会显示,请参阅Broken Demo。控制台中的唯一错误如下:
类型错误:bec[0].c[Math.floor(...)] 未定义
知道什么可能是错的吗?我应该如何调试此类错误?
