| SoVolumeRenderRenderModes Enumeration |
Composition mode.
Namespace: OIV.VolumeViz.Nodes
Assembly: OIV.VolumeViz (in OIV.VolumeViz.dll) Version: 10.3.0.0 (10.3.0.0)
SyntaxMembers| Member name | Value | Description | |
|---|---|---|---|
| VOLUME_RENDERING | 0 | Alpha compositing (Default) | |
| MIN_INTENSITY_PROJECTION | 1 | Minimum intensity projection (MinIP). The minimum value found along each ray is used to determine color. | |
| MAX_INTENSITY_PROJECTION | 2 | Maximum intensity projection (MIP). The maximum value found along each ray is used to determine color. | |
| SUM_INTENSITY_PROJECTION | 3 | Ray sum intensity projection (RSP). The values found along each ray are accumulated. Then the total value is normalized by the nominal number of samples for every ray (see OIV.VolumeViz.Nodes.SoVolumeRender.m_numSlices), which is the same for all rays. The values seen in shader functions, e.g. VVizComputeFragmentColor are still in the range 0..1, but the range of values that represents is quite different from the voxel data range. | |
| AVERAGE_INTENSITY_PROJECTION | 4 | Average Intensity projection (AIP). The values found along each ray are accumulated. The total value is divided by the actual number of samples along the current ray. The actual number of samples may be different for each ray. The resulting data range will be similar to the voxel data range but not necessarily the same. If there are many low, e.g. 0, valued voxels, the average may be very small. |
