Description: This function(s) can be used to interactively view any kind of 3D image volumes like CT and MRI, and for distance measurements or ROI selection in 2D slices.
It includes Maximum intensity projections (MIP), Volume Rendering (VR) , Slice render, and colored and Phong shaded Volume rendering.
Voxel opacity and color tables can be changed on the fly allowing also iso surface kind of renders.
The fast render algorithm which renders a 3D volume to a 2D image, is based on a Matlab coded implementation of the Shear-Warp transform, in which instead of rotating the viewer rays the slices are sheared. Platform: |

Description: 本文介绍的剪切图像顺序光线投射，一个新的体绘制方法。这种方法使得采样数据在图像质量相当于三个尺寸，最好的射线每像素体绘制算法（全图顺序），而在同一时间计算复杂度和保留空间相干性接近已知的最快算法（剪切变形）。在剪切图片的顺序，如剪切，弯曲，体积数据集重新取样片沿平行于其他物体的射线。不同剪切变形，但象纹理为基础的方法，射线演员通过对图像的像素的平面和样品中心点是在与每个切片射线的交点。-This paper describes shear-image order ray casting, a new method for volume rendering. This method renders sampled data in three dimensions with image quality equivalent to the best ofray-per-pixel volume rendering algorithms (full image order), while at the same time retaining computational complexity and spatial coherence near to that of the fastest known algorithm (shear-warp). In shear-image order, as in shear-warp, the volume data set is resampled along slices parallel to a face of the volume. Unlike shear-warp, but liketexture-based methods, rays are cast through the centers of pixels of the image plane and sample points are at the intersections of rays with each slice. Platform: |
