SoTexture3 Class Reference
[Node Classes]

#include <Inventor/nodes/SoTexture3.h>

Inherits SoTexture.

List of all members.


Detailed Description

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

Shape nodes within the scope of SoTexture3 nodes in the scenegraph (ie below the same SoSeparator and to the righthand 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 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

Texture mapping model.

Enumerator:
MODULATE  Texture image is modulated with polygon.
DECAL  Texture image overwrites polygon color.
BLEND  Blend image using blendColor.

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::SoTexture3 ( void   ) 

Constructor.

SoTexture3::~SoTexture3 (  )  [protected, virtual]

Destructor.


Member Function Documentation

int SoTexture3::getReadStatus ( void   )  [protected]

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

void SoTexture3::setReadStatus ( int  s  )  [protected]

Sets read status.

See also:
getReadStatus()


Member Data Documentation

Texture filename(s). Specify either this or use SoTexture3::images, not both. The depth of the volume is specifies 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().

Inline image data.

Wrapping strategy for the R coordinate (depth).

Wrapping strategy for the S coordinate.

Wrapping strategy for the T coordinate.

Texture model.

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

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.
