This is the abstract base class for all texture image nodes. It defines the common methods and fields that all texture image nodes have. When a texture image node is encountered during traversal, the associated image and parameters are applied to the current texture unit (see OIV.Inventor.Nodes.SoTextureUnit) and used to apply the texture to subsequent shapes.

Open Inventor provides multiple texture image nodes optimized for different purposes, including:

  • OIV.Inventor.Nodes.SoTexture2 The basic 2D texture image node. The image may be loaded from a file, loaded from an image in memory or created by rendering a scene graph.

  • OIV.Inventor.Nodes.SoExtTexture2 This node is similar to OIV.Inventor.Nodes.SoTexture2, but has specific optimizations that are valuable for applications that load a large number of textures from files.

  • OIV.Inventor.Nodes.SoIndexedTexture2 The first two nodes load an image containing color values that are directly applied to the geometry. This node considers each texel to be a data value that is mapped to a color using the color map defined by an OIV.Inventor.Nodes.SoColorMap node. This is very useful for "intensity" data sets.

  • OIV.Inventor.Nodes.SoTextureCubeMap This node loads a set of six images representing the faces of a cube. These are "shrink wrapped" onto the geometry similar to environment mapping, but without the need for a single specially warped environment image.

  • OIV.Inventor.Nodes.SoTexture3 This node defines a 3D texture map. The image may be loaded from a set of files or loaded directly from memory. A 3D texture may be used to load a volume data set, but note that the Open Inventor VolumeViz nodes are specifically implemented for this purpose (see OIV.VolumeViz.Nodes.SoVolumeData).

Applications may use the OIV.Inventor.Nodes.SoTexture.IsSupported(OIV.Inventor.Nodes.SoTexture.HW_Features) method to check if the graphics hardware supports a specific texture mapping feature.


This is an abstract class. See the reference page of a derived class for the format and default values.
