The new Surface rendering technology in Imaris 9 adopts Imaris’ proven Volume rendering technology based on a multi-resolution octree. Now it’s possible to visualize Surfaces of hundreds of Gigabytes in size. With this technology Imaris 9 can interactively render massive Surfaces consisting of billions of triangles.
The technology that enables Imaris 9 fast rendering of large surfaces is based on the following features:
Imaris 9 computes Surfaces in a block wise and multithreaded fashion to efficiently analyze large images (hundreds of Gigabytes). Thanks to this ground breaking new technology the computation will be possible for big images and will be significantly faster than in previous Imaris versions.
Our test images for Surfaces calculation time presented below are multiples of Wasp_embryo.ims created by using "Add slices" in Imaris. System specs: Win 7.1, 192GB RAM (Imaris internal memory limit of 64GB), CPU Intel Xeon E5-2687 (x2), Graphics Nvidia Quadro k5000, Data read from HDD, Cache set to SSD.
In addition to the well known 3D Surface rendering, within Imaris 9 Surfaces can be also rendered on a slicer (xy, xz, yz or oblique).
Blend and Normal Shading mode renderings now have separate display adjustment windows. The opacity transfer function is adjusted in a histogram on the Volume settings tab. These values are stored in the IMS file separately from the display min/max so that the renderings are restored from their saved state.
Zoom in and out of histograms in Imaris – simply use your mouse wheel. Pan the view by right-clicking on the zoom bar at the top of the histogram. Double Right-clicking on the zoom bar resets the view. Zoom into histograms at object Threshold and Classify steps, on object Filter tabs, and in the Coloc View.
Imaris 9 enables export of high resolution snapshots of the track editor window (tracks or lineage trees) including color coding and labels either as SVG vector graphics or as a high resolution .tiff.
Imaris 9 includes 2 new native file readers:
In addition, Imaris 9 searches the file reader plugin directory for DLLs that have the FileReader API. When such a DLL is found it will be added as a file reader to Imaris. If the file format contains multiple resolution levels Imaris will render those files in native mode without reading the entire file before rendering.
The Imaris Learning Center hosts a wide range of tutorial videos, how-to articles and webinars to guide you through the many features of Imaris. We have provided some links below which will get you started on some of our most recent developments.
