How to preserve real world scale of my datasets?

How can I raycast the scene to find an intersection?.

How to preserve real world scale of my datasets?.

See the importer documentation for more detailed information. VolumeRenderedObject obj = VolumeObjectFactory.CreateObject(dataset)

Use VolumeObjectFactory to create an object from the dataset:.

VolumeDataset dataset = importer.Import(file)

Call the Import()-function, which returns a Dataset:.

IImageFileImporter importer = ImporterFactory.CreateImageFileImporter(ImageFileFormat.NRRD)

Create an instance of an importer (Directly, or indirectly using the ImporterFactory):.

If you're on Windows or Linux, I recommend enabling the SimpleITK importer, which is a requirement for JPEG2000 compressed DICOM and NRRD. These can also be used with direct volume rendering mode. You can set this threshold yourself, by selecting the object and changing the "Visible value range" in the inspector. Isosurface rendering draws the first thing the ray hits, with a density higher than some threshold. Each rectangle can have one colour (see colour picker). Modify the two sliders to the right to change min/max alpha/opacity. Move the four sliders (bottom left) to modify size/position. Click "add rectangle" to add a new rectangle-shape. 2D Transfer Function: X-axis represents density and Y-axis represents gradient magnitude.Right-click to add new knots and click on an existing colour knot to modify its colour. The bottom gradient-coloured panel maps colour to density. Move the grey alpha knots to create a curve for opacity by density. 1D Transfer Function: X-axis represents density and Y-axis represents alpha (opaccity).Modifying transfer functions: Click "Volume Rendering" in the menu bar and select "1D Transfer Function" or "2D Transfer Function".Transfer functions map density (2D: also gradient magnitude) to a colour and opacity. It sends rays through the dataset, and uses "transfer functions" (1D or 2D) to determine the colour and opacity. Enable cubic interpolation: Use cubic interpolation of the 3D volume texture and gradient texture.ĭirect volume rendering is the most standard rendering mode.

Requires the above setting to be disabled. Enable early ray termination: Optimisation (you usually want this on)."Enable lighting": Enable lighting calculations during volume rendering.There are also some other settings that you can adjust: Maximum Intensity Projection (shows the maximum density).Direct Volume Rendering (using transfer functions).Select the model and find the "Volume Render Object" in the inspector. Simply select it in the scene view or scene hierarchy, and move/rotate it like normal. You can move the model like any other GameObject. The dataset must be of 3D nature, and contain several files - each being a slice along the Z axis. To import a DICOM dataset, click "Volume Rendering" and "Load DICOM" and select the folder containing your DICOM files. For the sample files you don't need to change anything. In the next menu you can optionally set the import setting for the raw dataset. Then select the dataset you wish to import. In the menu bar, click "Volume Rendering" and "Load raw dataset" Pick a file in the "DataFiles" folder (I recommend VisMale.raw).Select "Load Raw dataset" (or something else, if you already have a dataset you want to import).Click "Volume Rendering" in the menu bar.Unity 2018 1.5 or newer (should also work with some older versions, but I haven't tested).For more info, see the complete documentation. This Readme contains a quick introduction to the library. I also have a tutorial video that shows how to use the project Have any questions? Create an issue or contact me on Mastodon. I have written a tutorial explaining the basic implementation.
