Detailed Description

Abstract base class for texture mapping nodes.

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 SoTextureUnit) and used to apply the texture to subsequent shapes.

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

  • 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.
  • SoExtTexture2
    This node is similar to SoTexture2, but has specific optimizations that are valuable for applications that load a large number of textures from files.
  • 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 SoColorMap node. This is very useful for "intensity" data sets.
  • 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.
  • 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 SoVolumeData).

Applications may use the isSupported() method to check if the graphics hardware supports a specific texture mapping feature.

◆ Model

Texture Combiner Functions.

Enumerator
MODULATE 

The texture color is multiplied by the surface color.

DECAL 

In this mode, OpenGL requires that the specified texture image have either 3 or 4 components.

For a 3-component texture, the texture color replaces the surface color. For a 4-component texture, the texture color is blended with the surface color using the texture alpha value. See OpenGL documentation on glTexEnv for details.

BLEND 

Blends between the surface color and a specified blend color.

REPLACE 

The texture color replaces the surface color.

NOTE: enumeration value available since Open Inventor 4.0

ADD 

Adds incoming fragment and texture source colors.

NOTE: enumeration value available since Open Inventor 5.0

COMBINE 

Provides a wide range of programmable combiner functions using the incoming fragment color, texture source color, texture constant color, and the result of the previous texture environment stage as possible parameters.

NOTE: enumeration value available since Open Inventor 5.0

Definition at line 359 of file SoTexture.h.

◆ Wrap

Texture wrap type.

Enumerator
REPEAT 

Repeats texture outside 0-1 texture coordinate range.

CLAMP 

Clamps texture coordinates to lie within 0-1 range.

This wrap type is deprecated in OpenGL core profile. Consider using CLAMP_TO_EDGE instead.

CLAMP_TO_BORDER 

Clamps texture coordinates to a range coinciding with the centers of the border texels of a texture map at each mipmap level.


NOTE: enumeration value available since Open Inventor 5.0

CLAMP_TO_EDGE 

Clamps texture coordinates to a range coinciding with the centers of the edge texels of a texture map at each mipmap level.


NOTE: enumeration value available since Open Inventor 5.0

MIRRORED_REPEAT 

The texture image is repeated in such a way that every odd repetition is a mirror image.

Member Function Documentation

◆ getBitmapFileType()

FileType SoTexture::getBitmapFileType ( void  )

Gets the texture file format.

◆ getClassTypeId()

static SoType SoTexture::getClassTypeId ( )
static

Returns the type identifier for this class.


◆ getTypeId()

virtual SoType SoTexture::getTypeId ( ) const
virtual

Returns the type identifier for this specific instance.

Reimplemented from SoNode.

Reimplemented in SoExtTexture2, SoIndexedTexture2, SoTexture2, SoTexture3, SoTextureCubeMap, SoUniformGridClipping, and SoUniformGridProjectionClipping.

◆ isOverride()

virtual SbBool SoTexture::isOverride ( ) const
inlinevirtual

Returns the state of the override field.

Reimplemented from SoNode.

Definition at line 710 of file SoTexture.h.

◆ isSupported()

static SbBool SoTexture::isSupported ( HW_Feature  feature)
static

Returns information about hardware support for various texture features.

When using a debug build of Open Inventor, some "no context available" warning messages may be generated. You can ignore them or see SoGLExtension for an example of using SoGLContext to avoid them.

◆ readTexture()

static SbRasterImage * SoTexture::readTexture ( const SbString filename,
FileType  filetype = UNKNOWN 
)
static

Convenience function that loads the image data from any texture file supported by Open Inventor and returns an SbRasterImage object.

Returns null if the load fails for any reason.

If the file type is known, you may specify it using the FileType enum and Open Inventor will use the corresponding image reader. If filetype is UNKNOWN, Open Inventor will try to automatically determine which image reader should be used for the given file.

◆ setBitmapFileType()

void SoTexture::setBitmapFileType ( FileType  in_type)

Sets the texture file format.

Default is UNKNOWN. If file type is set to UNKNOWN, Open Inventor tries to determine the file type from the file name extension (e.g., foo. gif implies a GIF file). If the set or determined file type is not UNKNOWN, Open Inventor attempts to read the file as that format. If this fails, Open Inventor will try reading the file as each possible format in turn. It is not necessary to set the file type if the image file has the standard file name extension.

◆ setOverride()

virtual void SoTexture::setOverride ( const SbBool  state)
inlinevirtual

Set the state of the override field.

see SoNode::setOverride doc.

Member Data Documentation

◆ blendColor

SoSFColor SoTexture::blendColor

Color used for BLEND model.

Definition at line 570 of file SoTexture.h.

◆ borderColor

SoSFVec4f SoTexture::borderColor

Defines border color used for border texture filtering.

This value is only used if enableBorder is FALSE.

NOTE: field available since Open Inventor 5.0

Definition at line 586 of file SoTexture.h.

◆ enableBorder

SoSFBool SoTexture::enableBorder

Enables borders for textures.

This means that the border is already in the texture.

NOTE: field available since Open Inventor 5.0

Definition at line 578 of file SoTexture.h.

◆ enableCompressedTexture

SoSFBool SoTexture::enableCompressedTexture

Enables storage of textures on the graphics board in compressed form.

The application supplies textures as usual, then OpenGL compresses the textures. This can reduce usage of texture memory significantly, depending on the texture image.

To use this option, you must be using OpenGL 1.3 or higher, or your board must support the OpenGL GL_ARB_texture_compression extension.

NOTE: field available since Open Inventor 4.0

Definition at line 552 of file SoTexture.h.

◆ internalFormat

SoSFEnum SoTexture::internalFormat

Internal format for texture storage.

If not available on the graphics device, internalFormat is set back to AUTO_INTERNAL_FORMAT. Use enum InternalFormat. Default is AUTO_INTERNAL_FORMAT. If internal format is set to AUTO_INTERNAL_FORMAT texture precision could only be 16-bit maximum. To go beyond this limitation, you must set the internal format to the needed value.

NOTE: field available since Open Inventor 6.0

Definition at line 537 of file SoTexture.h.

◆ magFilter

SoSFEnum SoTexture::magFilter

Specifies the OpenGL magFilter.

Use enum Filter. Default is AUTO. Only the following Filter values are valid: AUTO, NEAREST, and LINEAR.

The magnification filter is used when the rendered size of the geometry is larger than the texture image to be applied (typically near objects). Effectively controls whether the GPU will select the "nearest" texel in the texture image or do linear interpolation (smoothing). Using NEAREST may allow better performance, but the LINEAR options produce much higher quality rendering.

Only the values NEAREST and LINEAR are valid in this field (see OpenGL specification).

The default value (AUTO) means that the magnification filter setting is actually controlled by the SoComplexity::textureQuality field.

NOTE: field available since Open Inventor 5.0

Definition at line 638 of file SoTexture.h.

◆ maxAnisotropy

SoSFFloat SoTexture::maxAnisotropy

Specifies on a per-texture object basis, the maximum degree of anisotropy to account for in texture filtering.

If the specified value is greater than the maximum supported by the graphics board, the value is clamped to GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT.

To use this option, you must be using OpenGL 1.1 or higher, or your board must support the OpenGL GL_EXT_filter_anisotropic extension.

◆ minFilter

SoSFEnum SoTexture::minFilter

Specifies the OpenGL minFilter.

Use enum Filter. Default is AUTO. The minification filter is used when the rendered size of the geometry is smaller than the texture image to be applied (typically far away objects). Effectively controls whether the GPU will select the "nearest" texel in the texture image or do linear interpolation (smoothing) or even interpolate between mipmap levels (subsampled versions of the base image). Using NEAREST may allow better performance, but the LINEAR options produce much higher quality rendering.

The default value (AUTO) means that the minification filter setting is actually controlled by the SoComplexity::textureQuality field.

◆ model

SoSFEnum SoTexture::model

Specifies how to map texture onto surface.

Use enum Model. Default is MODULATE.

◆ wrapS

SoSFEnum SoTexture::wrapS

Indicates what to do when texture coordinates in the S (horizontal) direction lie outside the range 0-1.

Use enum Wrap. Default is REPEAT.
