FLDVolren

Overview

Displays volume-rendering.

Description

Displays volume-rendering done based on the ray-tracing algorithm. Displays a co mposite image generated after taking into account transparency at all sampling points on a ray.

Note

olume rendering cannot be done in the Hardware Rendering(Open GL mode).
The data has to be 3D byte uniform structured cell data in order that volume re ndering can be used.

Input Ports

fld_in
AVS/Express Field(3D Structured Type Scalar Byte Uniform Data)

Output Ports

out_obj
AVS/Express DataObject

Parameters

Visible
Turns on and off the volume rendering display.

Reset
Resets all parameters to their original values.

Help
Displays help.

downsize level
Adjusts data precision based on sampling. The data has the precision of the original data when this value is 1 and precision decreases as the value increases.

Select Data
Selects the data for which volume rendering is required.

border value
The range of data values between 0 and 255 are divided into two and transparency is defined within each part. This boundary value defines the value that creates the two portions.

less than border
Defines the transparency for the portion less than the boundary value.

alpha of 0 value - Defines transparency for data value 0. Transparency is specified as a value in the range 0~1. Transparency increases as the value tends to 0.

alpah of X value - Defines transparency for data value X. Transparency is specified as a value in t he range 0~1. Transparency increases as the value tends to 0. X denotes the boundary value.

greater than border
Defines the transparency for the portion greater than the boundary value.

alpha of X value - Defines transparency for data value X. Transparency is specified as a value in the range 0~1. Transparency increases as the value tends to 0. X denotes the boundary value.

alpha of 255 value - Defines transparency for data value 255. Transparency is specified as a value in the range 0~1. Transparency increases as the value tends to 0.

smooth
A high-quality image with greater precision is obtained

alpha linear
Linearly interpolates transparency values defined for values less then (greater than) the boundary value. When this is turned off, no interpolation takes place and sharper images are obt ained.

Colormap Editor
Displays a panel to adjust the colormap.

Color Legend
Displays the color legend.
