This plugin shows stacks as slices, projections or volumes within a 3D-(xyz)-space. This plugin can be used with 8, 16, 32 bit and RGB stacks. The viewing angle
can be adjusted with the mouse. The position of the volume
may be changed by pressing the SHIFT-key and dragging the mouse.
Display Modes:
Slice: A slice through the volume.
Slice & Borders: A slice through the volume,
in addition the borders of the volume stack are displayed.
Max Projection: The volume is projected, maximum values (with alpha > 0) are kept.
Projection: Voxels are projected using the alpha values as weight.
Volume: A 3D redering is performed using alpha blending.
The Sampling value
controls how many samples
are used to blend the volume values. Higher values lead to better looking results, but this will be slower.
Transfer functions: Color LUTs can be used for display. Their curves may be modified with the mouse.
Transfer functions: Alpha values may be set using four different transfer functions using the luminance, gradient, mean and difference of the voxels.
1D: The alpha value may be drawn as a 1D-function: alpha(luminance)
2D Grad: The alpha value may be drawn as a 2D-function: alpha(luminance, gradient)
2D MD: The alpha value may be drawn as a 2D-function: alpha(mean, difference)
3D Fill: The alpha value may be set as a 3D-function: alpha(x,y,z). By clicking in the planar views alpha and color values may be assigned to voxels with similar intensities.
Interpolation modes may be chosen from Nearest Neighbor (fastest), triliniar and two tricubic modes (slowest).
The Distance slider adjusts the z screen position of the slice. Only voxels
at this distance or further away (for volumes and projections) are displayed. The colored lines in the planar views on
the left of the plugin indicate the intersection of the displayed slice and these views.
The positions of the planar views may be set with the xy, yz, and xz sliders.
The z-Aspect ratio of the volume is read automatically, but it can also be
set.
The Scale slider sets the zoom factor.
Axes: If checked, axes and text are shown.
Clipping: If checked, the clipping plane (at the selected distance) is shown.
Slice positions: If checked, the positions of planar views are
displayed.
This plugin can be called from a macro. This example
macro generates 36 volume views of the T1 Head sample stack
as it is rotated 360 degrees around the y axis in 10 degree increments.
setBatchMode(true);
run("T1 Head (2.4M, 16-bits)");
stack1 = getImageID;
stack2 = 0;
n = 36;
