Abstract base class for slices, SoVolumeSkin, SoHeightFieldRender, and SoVolumeRender nodes.
This class defines common properties for the SoOrthoSlice, SoObliqueSlice, SoFenceSlice, SoVolumeSkin, SoHeightFieldRender and SoVolumeRender nodes.
The interpolation field controls how the texture is interpolated.
The composition field is deprecated and should not be used. Instead specify the composition mode for volume rendering using the SoVolumeRender node.

Interpolation mode.
Used with interpolation field. Also used with interpolation field in volume geometry nodes, e.g. SoVolumeIndexedFaceSet::interpolation
Enumerator | |||||
---|---|---|---|---|---|
NEAREST | OpenGL "nearest neighbor" interpolation. | ||||
LINEAR | OpenGL linear interpolation (Default). This implies bi-linear interpolation for 2D textures (e.g. SoOrthoSlice, SoObliqueSlice, SoVolumeSkin, SoFenceSlice) and tri-linear interpolation for 3D textures (SoVolumeRender, SoVolumeGeometry). | ||||
TRILINEAR | Tri-linear interpolation for SoObliqueSlice. Tri-linear interpolation is used when extracting the 2D texture that will be applied to the slice, providing better image quality. | ||||
MULTISAMPLE_12 | Multi-sample interpolation for slice shapes. Interpolates data values using 12 samples around the voxel. This provides much higher image quality and specifically avoids rendering artifacts due to bi-linear interpolation. Only supported for 2D texture shapes (e.g. SoOrthoSlice, SoObliqueSlice, SoVolumeSkin, SoFenceSlice). Same as LINEAR for other nodes. | ||||
CUBIC | Cubic interpolation. This implies bi-cubic interpolation for 2D textures (e.g. SoOrthoSlice, SoObliqueSlice, SoVolumeSkin, SoFenceSlice) and tri-cubic interpolation for 3D textures (SoVolumeRender, SoVolumeGeometry). It gives smoother results, especially for volume rendering.
It is recomended to use SoInteractiveComplexity node to switch bewteen LINEAR interpolation while moving and CUBIC interpolation for Still frame: root->addChild(icplx);

Set an application defined SoProgressIndicator object which will raise an event before and after the rendering task, before and after each subtask (in this case: Texture creation and Geometry creation) and after each step in the subtasks which represents in most cases individual tiles of data.
Track loading progression with SoProgressIndicator::onEndStep event of SubTask "Loading Texture":
The example VolRend (examples/source/VolumeViz/VolRend) implements a loading progress bar in class EventRaisedProgressBar.
Limitations :
If set to NULL no events will be raised. Default is NULL.
Since Open Inventor 2023.2
Reimplemented in SoOrthoSlice.
SoDEPRECATED SoSFEnum SoVolumeShape::composition |
Specifies color composition mode.
Use enum Composition. Default is ALPHA_BLENDING.
ALPHA_BLENDING blends the R, G, and B components for each pixel based on the their alpha values.
SUM_INTENSITY draws the sum of the R, G, and B components for each pixel.
MAX_INTENSITY draws the maximum R, G, and B components for each pixel.
MIN_INTENSITY draws the minimum R, G, and B components for each pixel.
Note: In all modes, blending is done against the background color of the scene (or the object behind the volume). This means that, using MIN_INTENSITY for example, if the background color is black then 0,0,0 is already the minimum RGB value and the volume will not be visible. Generally when using MIN_INTENSITY the background color should be set to white (1,1,1) and when using MAX_INTENSITY or SUM_INTENSITY the background color should be set to black (0,0,0). To set the background color see the setBackgroundColor method of the appropriate RenderArea class, for example SoWinRenderArea on Windows.
NOTE: field available since Open Inventor 5.0.3
Definition at line 251 of file SoVolumeShape.h.
SoSFEnum SoVolumeShape::interpolation |
Interpolation mode.
Use enum SoVolumeShape::Interpolation. Default is LINEAR. NOTE: In most cases on modern graphics boards, indexed textures are used, so this refers to interpolation of volume data values.
