Module Description

Provides interactive visualization of 3D image data.

Usage

Examples, Use Cases & Tutorials

• Software Ray Casting
• GPU (GLSL) Ray Casting
• GPU (GLSL) Ray Casting II (Multi-Volume Rendering)

Volume rendering both background and foreground volumes. Background volume is rendered using compositing. Foreground volume is rendered using MIP. Background and foreground volumes are rendered together using alpha blending.

Fg volume only (MIP)

• OpenGL Texture Mapping
• Dual 3D View mode

Gradient Magnitude Opacity Modulation in Dual 3D View mode

• Volume-Following Mode

In Volume-Following mode, color and opacity transfer functions in the VolumeRendering module will follow window/level and threshold settings in the Volumes module for a uniform appearance on both slice view and 3D volume rendering view. To use, check VolumeRendering module -> Rendering panel -> Volume Property tab -> Follow Volumes Module check button.

In Volume-Following mode, window/level plus lookup table in Volumes module will be used to set colors in volume rendering. Threshold in Volumes module will be used to set opacity in volume rendering. Color and opacity transfer function editor also are disabled in Volume-Following mode because we are following volumes module now.
