NAME

SoTransformation -

The SoTransformation class is the abstract base class for transformation nodes.

To position and orient geometry within the 3D world space, various node types for transformations are used. These nodes all inherit the SoTransformation base class.

SYNOPSIS

#include <Inventor/nodes/SoTransformation.h>

Inherits SoNode.

Inherited by SoAntiSquish, SoGeoLocation, SoMatrixTransform, SoResetTransform, SoRotation, SoRotationXYZ, SoScale, SoSurroundScale, SoTransform, SoTranslation, and SoUnits.

Detailed Description

The SoTransformation class is the abstract base class for transformation nodes.

To position and orient geometry within the 3D world space, various node types for transformations are used. These nodes all inherit the SoTransformation base class.

Note that transformations will be accumulated through the scene graph, unless used under SoSeparator nodes, where the transformation matrix stack will be pushed and popped. Here is a short example demonstrating this principle:

 
 #Inventor V2.1 ascii
 
 Separator {
    BaseColor { rgb 1 0 0 }
    Cone { }
 
    Translation { translation 3 0 0 }
 
    Separator {
       Rotation { rotation 1 0 0  1.57 }
       BaseColor { rgb 0 1 0 }
       Cone { }
    } # SoSeparator restores transformation matrix here
 
    Translation { translation 3 0 0 }
 
    Rotation { rotation 1 0 0  1.57 }
    BaseColor { rgb 0 0 1 }
    Cone { }
 
    Translation { translation 3 0 0 }
 
    # Last SoRotation was not within SoSeparator, so this next
    # SoRotation will accumulate with the previous.
    Rotation { rotation 1 0 0  1.57 }
    BaseColor { rgb 1 1 0 }
    Cone { }
 }
   .fi
 
 
 Which results in the following scene:
