- Enum Constant Detail
  - VOLUME_RENDERING
```
public static final SoVolumeRender.RenderModes VOLUME_RENDERING
```
    Alpha compositing (Default). Also called Direct Volume Rendering (DVR) it blends the R, G, and B components for each data value along the sampling ray based on the alpha value (alpha blending).
  - MIN_INTENSITY_PROJECTION
```
public static final SoVolumeRender.RenderModes MIN_INTENSITY_PROJECTION
```
    Minimum intensity projection (MinIP). The minimum value found along each ray is used to determine color.
  - MAX_INTENSITY_PROJECTION
```
public static final SoVolumeRender.RenderModes MAX_INTENSITY_PROJECTION
```
    Maximum intensity projection (MIP). The maximum value found along each ray is used to determine color.
  - SUM_INTENSITY_PROJECTION
```
public static final SoVolumeRender.RenderModes SUM_INTENSITY_PROJECTION
```
    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 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
```
public static final SoVolumeRender.RenderModes AVERAGE_INTENSITY_PROJECTION
```
    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.
  - MAX_INTENSITY_DIFFERENCE_ACCUMULATION
```
public static final SoVolumeRender.RenderModes MAX_INTENSITY_DIFFERENCE_ACCUMULATION
```
    Maximum Intensity Difference Accumulation (MIDA). Assuming the important features of the volumetric datasets are of high scalar values, this mode changes the compositing behavior by decreasing the accumulated color and opacity when the incoming sample's scalar intensity is higher than any of those before it along the viewing ray. In this way, the high scalar value features in the volumetric datasets won't be occluded as much as in a standard compositing (i.e. VOLUME_RENDERING).
    See Instant volume visualization using maximum intensity difference accumulation. Stefan Bruckner and M. Eduard Groller. 2009. In Proceedings of the 11th Eurographics / IEEE - VGTC conference on Visualization (EuroVis'09) for details.
  - INTENSITY_DIFFERENCE_ACCUMULATION
```
public static final SoVolumeRender.RenderModes INTENSITY_DIFFERENCE_ACCUMULATION
```
    Intensity Difference Accumulation. This mode acts as MIDA but only the opacity of the accumulated color is affected and the modulation is based on the intensity difference of two consecutive samples. This mode should emphase the difference between two different structures with different scalar intensities.
    See Fast Volumetric Data Exploration with Importance-Based Accumulated Transparency Modulation. Wan Yong and Hansen Chuck, 2010, IEEE/ EG Symposium on Volume Graphics for details.
  - MAX_GRADIENT_DIFFERENCE_ACCUMULATION
```
public static final SoVolumeRender.RenderModes MAX_GRADIENT_DIFFERENCE_ACCUMULATION
```
    Maximum Gradient Difference Accumulation. This mode acts as INTENSITY_DIFFERENCE_ACCUMULATION but the composition is affected when the incoming sample's gradient is higher than any of those before it along the viewing ray. It aims at revealing important features (i.e. higher gradient transitions) all along the ray direction.
  - GRADIENT_DIFFERENCE_ACCUMULATION
```
public static final SoVolumeRender.RenderModes GRADIENT_DIFFERENCE_ACCUMULATION
```
    Gradient Difference Accumulation. This mode acts as MAX_GRADIENT_DIFFERENCE_ACCUMULATION but the opacity modulation is based on the gradient difference of two consecutive samples. It leads to a more transparent result, as more samples along the viewing ray contribute to the final result.

```
public static SoVolumeRender.RenderModes[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (SoVolumeRender.RenderModes c : SoVolumeRender.RenderModes.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static SoVolumeRender.RenderModes valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:

    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - valueOf
```
public static SoVolumeRender.RenderModes valueOf(int val)
```
    Returns the enum constant of this type with the specified integer value
    
    Returns:
