Detailed Description

The SoTexture3 class is used to map a 3D texture onto geometry.

Shape nodes within the scope of SoTexture3 nodes in the scene graph (i.e. below the same SoSeparator and to the right hand side of the SoTexture3) will have the texture applied according to each shape type's individual characteristics. See the documentation of the various shape types (SoFaceSet, SoCube, SoSphere, etc.) for information about the specifics of how the textures will be applied. An SoTexture3 node will override any previous encountered SoTexture2 nodes and vice versa. Mixing of SoTexture3 and SoTextureCoordinate2 (or the other way around) is legal, but the third texture coordinate component will be ignored (set to 0.0).

Member Enumeration Documentation

◆ Model

Texture mapping model.

Enumerator
MODULATE 

Texture image is modulated with polygon.

DECAL 

Texture image overwrites polygon color.

BLEND 

Blend image using blendColor.

◆ Wrap

Enum used to specify wrapping strategy.

Enumerator
REPEAT 

Repeat texture when coordinate is not between 0 and 1.

CLAMP 

Clamp coordinate between 0 and 1.

Constructor & Destructor Documentation

◆ SoTexture3()

Constructor.

◆ ~SoTexture3()

SoTexture3::~SoTexture3 ( )
protectedvirtual

Destructor.

Member Function Documentation

◆ getTypeId()

SoType SoTexture3::getTypeId ( void  ) const
virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Usage example:

void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the predefined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the top level superclasses for the various class groups.

Reimplemented from SoTexture.

◆ getFieldData()

const SoFieldData * SoTexture3::getFieldData ( void  ) const
protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoTexture.

◆ doAction()

void SoTexture3::doAction ( SoAction action)
virtual

This function performs the typical operation of a node for any action.

Reimplemented from SoTexture.

◆ GLRender()

void SoTexture3::GLRender ( SoGLRenderAction action)
virtual

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.

Reimplemented from SoTexture.

◆ callback()

void SoTexture3::callback ( SoCallbackAction action)
virtual

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoTexture.

◆ readInstance()

SbBool SoTexture3::readInstance ( SoInput in,
unsigned short  flags 
)
protectedvirtual

This method is mainly intended for internal use during file import operations.

It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistent representation of an instance of this class type.

TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went OK or not. The import process should be robust and handle corrupted input streams by returning FALSE.

flags is used internally during binary import when reading user extension nodes, group nodes or engines.

Reimplemented from SoNode.

◆ notify()

void SoTexture3::notify ( SoNotList l)
protectedvirtual

Notifies all auditors for this instance when changes are made.

Reimplemented from SoNode.

◆ getReadStatus()

int SoTexture3::getReadStatus ( void  )
protected

Returns read status. 1 for success, 0 for failure.

◆ setReadStatus()

void SoTexture3::setReadStatus ( int  s)
protected

Sets read status.

getReadStatus()

Member Data Documentation

◆ filenames

SoMFString SoTexture3::filenames

Texture filename(s). Specify either this or use SoTexture3::images, not both. The depth of the volume is specified by the number of filenames specified. All images must have the same dimensions and number of components. NB! A field sensor is attached to this field internally and reloads all images when this field changes. You must therefore be careful when setting this field and either use startEditing()/finishEditing() or set all values with one function call; setValues().

◆ images

SoSFImage3 SoTexture3::images

Inline image data.

◆ wrapR

SoSFEnum SoTexture3::wrapR

Wrapping strategy for the R coordinate (depth).

◆ wrapS

SoSFEnum SoTexture3::wrapS

Wrapping strategy for the S coordinate.

◆ wrapT

SoSFEnum SoTexture3::wrapT

Wrapping strategy for the T coordinate.

◆ model

SoSFEnum SoTexture3::model

Texture model.

◆ blendColor

SoSFColor SoTexture3::blendColor

Blend color. Used when SoTexture3::model is SoTexture3::BLEND.

◆ enableCompressedTexture

SoSFBool SoTexture3::enableCompressedTexture

Hint to Coin that compressed textures should be used if this is supported by the graphics hardware and OpenGL drivers. Using compressed textures usually reduces texture memory usage for a texture by 4-6 times.
