IfcTextureCoordinateGenerator
Definition
from IAI: The IfcTextureCoordinateGenerator
describes a procedurally defined mapping function with input parameter
to map 2D texture coordinates to 3D geometry vertices. The allowable Mode
values and input Parameter
need to be agreed upon in
implementer agreements.
The following additional
definitions from ISO/IEC FCD 19775:200x,
the Extensible 3D (X3D)
specification, apply:
TextureCoordinateGenerator
supports the automatic
generation of texture coodinates for geometric shapes. This node can be
used to set the texture coordinates. The mode field describes the
algorithm used to compute texture coordinates, the following modes are
forseen in X3D:
SPHERE,
CAMERASPACENORMAL, CAMERASPACEPOSITION,
CAMERASPACEREFLECTIONVECTOR, SPHERE-LOCAL, COORD, COORD-EYE, NOISE,
NOISE-EYE, SPHERE-REFLECT, SPHERE-REFLECT-LOCAL
