The cross-section can be scaled and rotated at each spine point to produce a wide variety of shapes\&. An Extrusion node is defined by: .PP .PD 0 .IP "\(bu" 1 a 2D crossSection piecewise linear curve (described as a series of connected vertices); .PP .PD 0 .IP "\(bu" 1 a 3D spine piecewise linear curve (also described as a series of connected vertices); .PP .PD 0 .IP "\(bu" 1 a list of 2D scale parameters; .PP .PD 0 .IP "\(bu" 1 a list of 3D orientation parameters\&. .PP \fIAlgorithmic\fP \fIdescription\fP .PP Shapes are constructed as follows\&. The cross-section curve, which starts as a curve in the Y=0 plane, is first scaled about the origin by the first scale parameter (first value scales in X, second value scales in Z)\&. It is then translated by the first spine point and oriented using the first orientation parameter (as explained later)\&. The same procedure is followed to place a cross- section at the second spine point, using the second scale and orientation values\&. Corresponding vertices of the first and second cross-sections are then connected, forming a quadrilateral polygon between each pair of vertices\&. This same procedure is then repeated for the rest of the spine points, resulting in a surface extrusion along the spine\&. .PP The final orientation of each cross-section is computed by first orienting it relative to the spine segments on either side of point at which the cross-section is placed\&. This is known as the spine-aligned cross-section plane (SCP), and is designed to provide a smooth transition from one spine segment to the next (see Figure \fB6\&.6\fP)\&. The SCP is then rotated by the corresponding orientation value\&. This rotation is performed relative to the SCP\&. For example, to impart twist in the cross- section, a rotation about the Y-axis (0 1 0) would be used\&. Other orientations are valid and rotate the cross-section out of the SCP\&. .PP Figure \fB6\&.6\fP .PP The SCP is computed by first computing its Y-axis and Z-axis, then taking the cross product of these to determine the X-axis\&. These three axes are then used to determine the rotation value needed to rotate the Y=0 plane to the SCP\&. This results in a plane that is the approximate tangent of the spine at each point, as shown in Figure \fB6\&.6\fP\&. First the Y-axis is determined, as follows: .PP Let n be the number of spines and let i be the index variable satisfying 0 <= i < n: .PP .PD 0 .IP "\(bu" 1 For all points other than the first or last: The Y-axis for spine[i] is found by normalizing the vector defined by (spine[i+1] .IP " \(bu" 4 spine[i-1])\&. .PP .PP .PD 0 .IP "\(bu" 1 If the spine curve is closed: The SCP for the first and last points is the same and is found using (spine[1] - spine[n-2]) to compute the Y-axis\&. .PP .PD 0 .IP "\(bu" 1 If the spine curve is not closed: The Y-axis used for the first point is the vector from spine[0] to spine[1], and for the last it is the vector from spine[n-2] to spine[n-1]\&. .PP The Z-axis is determined as follows: .PP .PD 0 .IP "\(bu" 1 For all points other than the first or last: Take the following cross-product: .PP .PP .nf Z = (spine[i+1] - spine[i]) × (spine[i-1] - spine[i]) .fi .PP .PP .PD 0 .IP "\(bu" 1 If the spine curve is closed: The SCP for the first and last points is the same and is found by taking the following cross- product: .PP .PP .nf Z = (spine[1] - spine[0]) × (spine[n-2] - spine[0]) .fi .PP .PP .PD 0 .IP "\(bu" 1 If the spine curve is not closed: The Z-axis used for the first spine point is the same as the Z-axis for spine[1]\&. The Z- axis used for the last spine point is the same as the Z-axis for spine[n-2]\&. .PP .PD 0 .IP "\(bu" 1 After determining the Z-axis, its dot product with the Z-axis of the previous spine point is computed\&. If this value is negative, the Z-axis is flipped (multiplied by -1)\&. In most cases, this prevents small changes in the spine segment angles from flipping the cross-section 180 degrees\&. .PP Once the Y- and Z-axes have been computed, the X-axis can be calculated as their cross-product\&. .PP \fISpecial\fP \fICases\fP .PP If the number of scale or orientation values is greater than the number of spine points, the excess values are ignored\&. If they contain one value, it is applied at all spine points\&. The results are undefined if the number of scale or orientation values is greater than one but less than the number of spine points\&. The scale values shall be positive\&. .PP If the three points used in computing the Z-axis are collinear, the cross-product is zero so the value from the previous point is used instead\&. If the Z-axis of the first point is undefined (because the spine is not closed and the first two spine segments are collinear) then the Z-axis for the first spine point with a defined Z-axis is used\&. .PP If the entire spine is collinear, the SCP is computed by finding the rotation of a vector along the positive Y-axis (v1) to the vector formed by the spine points (v2)\&. The Y=0 plane is then rotated by this value\&. If two points are coincident, they both have the same SCP\&. If each point has a different orientation value, then the surface is constructed by connecting edges of the cross-sections as normal\&. This is useful in creating revolved surfaces\&. .PP Note: combining coincident and non-coincident spine segments, as well as other combinations, can lead to interpenetrating surfaces which the extrusion algorithm makes no attempt to avoid\&. .PP \fICommon\fP \fICases\fP .PP The following common cases are among the effects which are supported by the Extrusion node: .PP .PD 0 .IP "\(bu" 1 Surfaces of revolution: If the cross-section is an approximation of a circle and the spine is straight, the Extrusion is equivalent to a surface of revolution, where the scale parameters define the size of the cross-section along the spine\&. .PP .PD 0 .IP "\(bu" 1 Uniform extrusions: If the scale is (1, 1) and the spine is straight, the cross-section is extruded uniformly without twisting or scaling along the spine\&. The result is a cylindrical shape with a uniform cross section\&. .PP .PD 0 .IP "\(bu" 1 Bend/twist/taper objects: These shapes are the result of using all fields\&. The spine curve bends the extruded shape defined by the cross-section, the orientation parameters (given as rotations about the Y-axis) twist it around the spine, and the scale parameters taper it (by scaling about the spine)\&. .PP \fIOther\fP \fIFields\fP .PP Extrusion has three parts: the sides, the beginCap (the surface at the initial end of the spine) and the endCap (the surface at the final end of the spine)\&. The caps have an associated SFBool field that indicates whether each exists (TRUE) or doesn't exist (FALSE)\&. .PP When the beginCap or endCap fields are specified as TRUE, planar cap surfaces will be generated regardless of whether the crossSection is a closed curve\&. If crossSection is not a closed curve, the caps are generated by adding a final point to crossSection that is equal to the initial point\&. An open surface can still have a cap, resulting (for a simple case) in a shape analogous to a soda can sliced in half vertically\&. These surfaces are generated even if spine is also a closed curve\&. If a field value is FALSE, the corresponding cap is not generated\&. .PP Texture coordinates are automatically generated by Extrusion nodes\&. Textures are mapped so that the coordinates range in the U direction from 0 to 1 along the crossSection curve (with 0 corresponding to the first point in crossSection and 1 to the last) and in the V direction from 0 to 1 along the spine curve (with 0 corresponding to the first listed spine point and 1 to the last)\&. If either the endCap or beginCap exists, the crossSection curve is uniformly scaled and translated so that the larger dimension of the cross-section (X or Z) produces texture coordinates that range from \fB0\&.0\fP to \fB1\&.0\fP\&. The beginCap and endCap textures' S and T directions correspond to the X and Z directions in which the crossSection coordinates are defined\&. .PP The browser shall automatically generate normals for the Extrusion node,using the creaseAngle field to determine if and how normals are smoothed across the surface\&. Normals for the caps are generated along the Y-axis of the SCP, with the ordering determined by viewing the cross-section from above (looking along the negative Y-axis of the SCP)\&. By default, a beginCap with a counterclockwise ordering shall have a normal along the negative Y-axis\&. An endCap with a counterclockwise ordering shall have a normal along the positive Y-axis\&. .PP Each quadrilateral making up the sides of the extrusion are ordered from the bottom cross-section (the one at the earlier spine point) to the top\&. So, one quadrilateral has the points: .PP .PP .nf spine[0](crossSection[0], crossSection[1]) spine[1](crossSection[1], crossSection[0]) .fi .PP .PP in that order\&. By default, normals for the sides are generated as described in 4\&.6\&.3, Shapes and geometry (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.3)\&. .PP For instance, a circular crossSection with counterclockwise ordering and the default spine form a cylinder\&. With solid TRUE and ccw TRUE, the cylinder is visible from the outside\&. Changing ccw to FALSE makes it visible from the inside\&. The ccw, solid, convex, and creaseAngle fields are described in 4\&.6\&.3, Shapes and geometry (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.3)\&. .SH "Constructor & Destructor Documentation" .PP .SS "SoVRMLExtrusion::SoVRMLExtrusion (\fBvoid\fP)" Constructor\&. .SS "SoVRMLExtrusion::~SoVRMLExtrusion ()\fC [protected]\fP, \fC [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "\fBSoType\fP SoVRMLExtrusion::getClassTypeId (\fBvoid\fP)\fC [static]\fP" This static method returns the \fBSoType\fP object associated with objects of this class\&. .br .SS "\fBSoType\fP SoVRMLExtrusion::getTypeId (\fBvoid\fP) const\fC [virtual]\fP" Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&.
