Module Description

Provides interactive visualization of 3D image data.

Usage

Use Cases, Examples

• Pausing VolumeRendering module in scene loading

The VolumeRendering module can be paused in scene loading by un-checking the "Monitor Scene Loading Event" check button. Re-checking the check button will flush the paused pipeline and initialize the module using the loaded scene.

• Multi-Volume GPU Ray Casting

VolumeRendering module has the capability to blend two (bg and fg) volumes in one rendering pipeline. User may select different rendering technique for bg or fg volumes. Different blending options are also available.

Currently under development. Available rendering techniques: Composite (bg) + Composite (fg) + OR blending, Composite (bg) + Composite (fg) + AND blending, Composite (bg) + MIP (fg), MIP (bg) + MIP (fg).

Bg volume only (Composite)

Bg and Fg volume

Fg volume only (MIP)

• Dual 3D View mode

VTK GPU Ray Casting doesn't support the 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.
