Constructor Detail

BinaryStlFacetDefinition

public BinaryStlFacetDefinition(List<Vector3D> vertices,
                                Vector3D normal,
                                int attributeValue)

Construct a new instance.

Parameters:

vertices - facet vertices

normal - facet normal

attributeValue - 2-byte attribute value

Method Detail

getAttributeValue

public int getAttributeValue()

Get the 2-byte attribute value (known as the "attribute byte count") stored at the end of the STL facet definition binary representation. This value is typically set to zero but non-standard implementations may choose to store other values here.

The bytes are stored with the first byte in the upper portion (bits 8-15) of the int and the second byte in the lower portion (bits 0-7).

Returns:

2-byte attribute value for the facet
