To open a file click onto the button with the blue folder. The software is able to read 16-bit (12-bit used) and 8-bit file with a 6 byte header containing the X, Y, and Z-dimensions.

There are 3 fields to apply different scaling for the X,Y and Z axis. The scaling is only valid for the rendering mode Raycasting.

To look at the raw slices select one of the 3 viewing directions with the radio button "Viewmode". To change the current slice drag the scrollbar.

It is also possible to apply a transfer function to the slices.

With this viewmode it is possible to look at the dataset from any direction. To turn the dataset select the viewing angle with the 2 sliders "Turn X" and "Turn Z". It is also possible to enter a value into the fields or drag the dataset in the viewing window with the mouse.

The field resolution defines the rendering resoultion for the cube. A higher resulution delivers higher quality but also slows down the rendering. To get an early preview it is good to select "progressive refinement". The drawback of this option is also a slower rendering.

To open a transfer function editor hit the "Edit Transferfunction" button.

With the first two buttons it is possible to load and save the current transfer function. The interpolator defines the way to determine the colors between two points. The checkbox "gradient intensified" determines if the gradient of the dataset should be taken into account for the calculation of the alpha value.

To add a clasification point double click into the histogram. The default color is white. The height of the point determines the alpha. To change the color of point select the element and double click.

In the bottom of the window is a complete list of all clasification points with the exact values.

To delete a point select the line in the table or select the point in the histogram and hit the delete button.

It is possible to define more than one transfer function and cut the dataset into different areas. To activate a second transfer function the checkbox "2nd Transferfunction" must be activated. The button "copy" copies the default transfer function. The button "Edit" opens another transfer function editor.

The sliders for U, V and Distance control the position of the cutting plane. U is the angel for the normal vector of the plane on the X axis, V on the Z axis. The distance value defines the distance from the center point.

Its also possible to define a 3rd transfer function. The default function has the lowest priority, the 3rd transfer function the highest.
