 CGeom2dConvert_BSplineCurveKnotSplittingAn algorithm to determine points at which a BSpline curve should be split in order to obtain arcs of the same continuity. If you require curves with a minimum continuity for your computation, it is useful to know the points between which an arc has a continuity of a given order. The continuity order is given at the construction time. For a BSpline curve, the discontinuities are localized at the knot values. Between two knot values the BSpline is infinitely and continuously differentiable. At a given knot, the continuity is equal to: Degree - Mult, where Degree is the degree of the BSpline curve and Mult is the multiplicity of the knot.

 CGeomConvert_BSplineCurveKnotSplittingAn algorithm to determine points at which a BSpline curve should be split in order to obtain arcs of the same continuity. If you require curves with a minimum continuity for your computation, it is useful to know the points between which an arc has a continuity of a given order. The continuity order is given at the construction time. For a BSpline curve, the discontinuities are localized at the knot values. Between two knot values the BSpline is infinitely and continuously differentiable. At a given knot, the continuity is equal to: Degree - Mult, where Degree is the degree of the BSpline curve and Mult is the multiplicity of the knot. It is possible to compute the arcs which correspond to this splitting using the global function SplitBSplineCurve provided by the package GeomConvert.

The continuity order is given at the construction time. It is possible to compute the surface patches corresponding to the splitting with the method of package SplitBSplineSurface. For a B-spline surface the discontinuities are localised at the knot values. Between two knots values the B-spline is infinitely continuously differentiable. For each parametric direction at a knot of range index the continuity in this direction is equal to : Degree - Mult (Index) where Degree is the degree of the basis B-spline functions and Mult the multiplicity of the knot of range Index in the given direction. If for your computation you need to have B-spline surface with a minima of continuity it can be interesting to know between which knot values, a B-spline patch, has a continuity of given order. This algorithm computes the indexes of the knots where you should split the surface, to obtain patches with a constant continuity given at the construction time. If you just want to compute the local derivatives on the surface you don't need to create the BSpline patches, you can use the functions LocalD1, LocalD2, LocalD3, LocalDN of the class BSplineSurface from package Geom

 CHLRAlgoIn order to have the precision required in industrial design, drawings need to offer the possibility of removing lines, which are hidden in a given projection. To do this, the Hidden Line Removal component provides two algorithms: HLRBRep_Algo and HLRBRep_PolyAlgo. These algorithms remove or indicate lines hidden by surfaces. For a given projection, they calculate a set of lines characteristic of the object being represented. They are also used in conjunction with extraction utilities, which reconstruct a new, simplified shape from a selection of calculation results.

 CLaw_BSplineKnotSplittingFor a B-spline curve the discontinuities are localised at the knot values and between two knots values the B-spline is infinitely continuously differentiable. At a knot of range index the continuity is equal to : Degree - Mult (Index) where Degree is the degree of the basis B-spline functions and Mult the multiplicity of the knot of range Index. If for your computation you need to have B-spline curves with a minima of continuity it can be interesting to know between which knot values, a B-spline curve arc, has a continuity of given order. This algorithm computes the indexes of the knots where you should split the curve, to obtain arcs with a constant continuity given at the construction time. The splitting values are in the range [FirstUKnotValue, LastUKnotValue] (See class B-spline curve from package Geom). If you just want to compute the local derivatives on the curve you don't need to create the B-spline curve arcs, you can use the functions LocalD1, LocalD2, LocalD3, LocalDN of the class BSplineCurve

 CPrecisionThe Precision package offers a set of functions defining precision criteria for use in conventional situations when comparing two numbers. Generalities It is not advisable to use floating number equality. Instead, the difference between numbers must be compared with a given precision, i.e. : Standard_Real x1, x2 ; x1 = ... x2 = ... If ( x1 == x2 ) ... should not be used and must be written as indicated below: Standard_Real x1, x2 ; Standard_Real Precision = ... x1 = ... x2 = ... If ( Abs ( x1 - x2 ) < Precision ) ... Likewise, when ordering floating numbers, you must take the following into account : Standard_Real x1, x2 ; Standard_Real Precision = ... x1 = ... ! a large number x2 = ... ! another large number If ( x1 < x2 - Precision ) ... is incorrect when x1 and x2 are large numbers ; it is better to write : Standard_Real x1, x2 ; Standard_Real Precision = ... x1 = ... ! a large number x2 = ... ! another large number If ( x2 - x1 > Precision ) ... Precision in Cas.Cade Generally speaking, the precision criterion is not implicit in Cas.Cade. Low-level geometric algorithms accept precision criteria as arguments. As a rule, they should not refer directly to the precision criteria provided by the Precision package. On the other hand, high-level modeling algorithms have to provide the low-level geometric algorithms that they call, with a precision criteria. One way of doing this is to use the above precision criteria. Alternatively, the high-level algorithms can have their own system for precision management. For example, the Topology Data Structure stores precision criteria for each elementary shape (as a vertex, an edge or a face). When a new topological object is constructed, the precision criteria are taken from those provided by the Precision package, and stored in the related data structure. Later, a topological algorithm which analyses these objects will work with the values stored in the data structure. Also, if this algorithm is to build a new topological object, from these precision criteria, it will compute a new precision criterion for the new topological object, and write it into the data structure of the new topological object. The different precision criteria offered by the Precision package, cover the most common requirements of geometric algorithms, such as intersections, approximations, and so on. The choice of precision depends on the algorithm and on the geometric space. The geometric space may be :

This package is used by VrmlConverter package. The developer should already be familiar with VRML specification before using this package
 CVrml_ConeDefines a Cone node of VRML specifying geometry shapes. This node represents a simple cone, whose central axis is aligned with the y-axis. By default , the cone is centred at (0,0,0) and has size of -1 to +1 in the all three directions. the cone has a radius of 1 at the bottom and height of 2, with its apex at 1 and its bottom at -1. The cone has two parts: the sides and the bottom
 CVrml_CubeDefines a Cube node of VRML specifying geometry shapes. This node represents a cuboid aligned with the coordinate axes. By default , the cube is centred at (0,0,0) and measures 2 units in each dimension, from -1 to +1. A cube's width is its extent along its object-space X axis, its height is its extent along the object-space Y axis, and its depth is its extent along its object-space Z axis
 CVrml_CylinderDefines a Cylinder node of VRML specifying geometry shapes. This node represents a simple capped cylinder centred around the y-axis. By default , the cylinder is centred at (0,0,0) and has size of -1 to +1 in the all three dimensions. The cylinder has three parts: the sides, the top (y=+1) and the bottom (y=-1)

 CVrml_GroupDefines a Group node of VRML specifying group properties. This node defines the base class for all group nodes. Group is a node that contains an ordered list of child nodes. This node is simply a container for the child nodes and does not alter the traversal state in any way. During traversal, state accumulated for a child is passed on to each successive child and then to the parents of the group (Group does not push or pop traversal state as separator does)
 CVrml_InfoDefines a Info node of VRML specifying properties of geometry and its appearance. It is used to store information in the scene graph, Typically for application-specific purposes, copyright messages, or other strings
 CVrml_InstancingDefines "instancing" - using the same instance of a node multiple times. It is accomplished by using the "DEF" and "USE" keywords. The DEF keyword both defines a named node, and creates a single instance of it. The USE keyword indicates that the most recently defined instance should be used again. If several nades were given the same name, then the last DEF encountered during parsing "wins". DEF/USE is limited to a single file
 CVrml_MaterialBindingDefines a MaterialBinding node of VRML specifying properties of geometry and its appearance. Material nodes may contain more than one material. This node specifies how the current materials are bound to shapes that follow in the scene graph. Each shape node may interpret bindings differently. For example, a Sphere node is always drawn using the first material in the material node, no matter what the current MaterialBinding, while a Cube node may use six different materials to draw each of its six faces, depending on the MaterialBinding
 CVrml_MatrixTransformDefines a MatrixTransform node of VRML specifying matrix and transform properties. This node defines 3D transformation with a 4 by 4 matrix. By default : a11=1 a12=0 a13=0 a14=0 a21=0 a22=1 a23=0 a24=0 a31=0 a32=0 a33=1 a34=0 a41=0 a42=0 a43=0 a44=1 It is written to the file in row-major order as 16 Real numbers separated by whitespace. For example , matrix expressing a translation of 7.3 units along the X axis is written as: 1 0 0 0 0 1 0 0 0 0 1 0 7.3 0 0 1
 CVrml_NormalBindingDefines a NormalBinding node of VRML specifying properties of geometry and its appearance. This node specifies how the current normals are bound to shapes that follow in the scene graph. Each shape node may interpret bindings differently. The bindings for faces and vertices are meaningful only for shapes that are made from faces and vertices. Similarly, the indexed bindings are only used by the shapes that allow indexing. For bindings that require multiple normals, be sure to have at least as many normals defined as are necessary; otherwise, errors will occur
 CVrml_OrthographicCameraOrthographicCamera node of VRML specifying properties of cameras. An orthographic camera defines a parallel projection from a viewpoint. This camera does not diminish objects with distance, as a PerspectiveCamera does. The viewing volume for an orthographic camera is a rectangular parallelepiped (a box)
 CVrml_PerspectiveCameraPerspectiveCamera node of VRML specifying properties of cameras. A perspective camera defines a perspective projection from a viewpoint. The viewing volume for a perspective camera is a truncated right pyramid
 CVrml_PointLightDefines a point light node of VRML specifying properties of lights. This node defines a point light source at a fixed 3D location A point source illuminates equally in all directions; that is omni-directional. Color is written as an RGB triple. Light intensity must be in the range 0.0 to 1.0, inclusive
 CVrml_PointSetDefines a PointSet node of VRML specifying geometry shapes
 CVrml_RotationDefines a Rotation node of VRML specifying matrix and transform properties. This node defines a 3D rotation about an arbitrary axis through the origin. By default : myRotation = (0 0 1 0)
 CVrml_ScaleDefines a Scale node of VRML specifying transform properties. This node defines a 3D scaling about the origin. By default : myRotation = (1 1 1)
 CVrml_SeparatorDefines a Separator node of VRML specifying group properties. This group node performs a push (save) of the traversal state before traversing its children and a pop (restore) after traversing them. This isolates the separator's children from the rest of the scene graph. A separator can include lights, cameras, coordinates, normals, bindings, and all other properties. Separators can also perform render culling. Render culling skips over traversal of the separator's children if they are not going to be rendered, based on the comparison of the separator's bounding box with the current view volume. Culling is controlled by the renderCulling field. These are set to AUTO by default, allowing the implementation to decide whether or not to cull
 CVrml_SFRotationDefines SFRotation type of VRML field types. The 4 values represent an axis of rotation followed by amount of right-handed rotation about the that axis, in radians
 CVrml_ShapeHintsDefines a ShapeHints node of VRML specifying properties of geometry and its appearance. The ShapeHints node indicates that IndexedFaceSets are solid, contain ordered vertices, or contain convex faces. These hints allow VRML implementations to optimize certain rendering features. Optimizations that may be performed include enabling back-face culling and disabling two-sided lighting. For example, if an object is solid and has ordered vertices, an implementation may turn on backface culling and turn off two-sided lighting. To ensure that an IndexedFaceSet can be viewed from either direction, set shapeType to be UNKNOWN_SHAPE_TYPE. If you know that your shapes are closed and will alwsys be viewed from the outside, set vertexOrdering to be either CLOCKWISE or COUNTERCLOCKWISE (depending on how you built your object), and set shapeType to be SOLID. Placing this near the top of your VRML file will allow the scene to be rendered much faster. The ShapeHints node also affects how default normals are generated. When an IndexedFaceSet has to generate default normals, it uses the creaseAngle field to determine which edges should be smoothly shaded and which ones should have a sharp crease. The crease angle is the angle between surface normals on adjacent polygons. For example, a crease angle of .5 radians (the default value) means that an edge between two adjacent polygonal faces will be smooth shaded if the normals to the two faces form an angle that is less than .5 radians (about 30 degrees). Otherwise, it will be faceted
 CVrml_SphereDefines a Sphere node of VRML specifying geometry shapes. This node represents a sphere. By default , the sphere is centred at (0,0,0) and has a radius of 1
 CVrml_SpotLightSpot light node of VRML nodes specifying properties of lights. This node defines a spotlight light source. A spotlight is placed at a fixed location in 3D-space and illuminates in a cone along a particular direction. The intensity of the illumination drops off exponentially as a ray of light diverges from this direction toward the edges of cone. The rate of drop-off and agle of the cone are controlled by the dropOfRate and cutOffAngle Color is written as an RGB triple. Light intensity must be in the range 0.0 to 1.0, inclusive
 CVrml_SwitchDefines a Switch node of VRML specifying group properties. This group node traverses one, none, or all of its children. One can use this node to switch on and off the effects of some properties or to switch between different properties. The whichChild field specifies the index of the child to traverse, where the first child has index 0. A value of -1 (the default) means do not traverse any children. A value of -3 traverses all children, making the switch behave exactly like a regular Group
 CVrml_Texture2Defines a Texture2 node of VRML specifying properties of geometry and its appearance. This property node defines a texture map and parameters for that map The texture can be read from the URL specified by the filename field. To turn off texturing, set the filename field to an empty string (""). Textures can alsobe specified inline by setting the image field to contain the texture data. By default : myFilename ("") myImage (0 0 0) myWrapS (Vrml_REPEAT) myWrapT (Vrml_REPEAT)
 CVrml_Texture2TransformDefines a Texture2Transform node of VRML specifying properties of geometry and its appearance. This node defines a 2D transformation applied to texture coordinates. This affect the way textures are applied to the surfaces of subsequent shapes. Transformation consisits of(in order) a non-uniform scale about an arbitrary center point, a rotation about that same point, and a translation. This allows a user to change the size and position of the textures on the shape. By default : myTranslation (0 0) myRotation (0) myScaleFactor (1 1) myCenter (0 0)
 CVrml_TransformDefines a Transform of VRML specifying transform properties. This node defines a geometric 3D transformation consisting of (in order) a (possibly) non-uniform scale about an arbitrary point, a rotation about an arbitrary point and axis and translation. By default : myTranslation (0,0,0) myRotation (0,0,1,0) myScaleFactor (1,1,1) myScaleOrientation (0,0,1,0) myCenter (0,0,0)
 CVrml_TransformSeparatorDefines a TransformSeparator node of VRML specifying group properties. This group node is similar to separator node in that it saves state before traversing its children and restores it afterwards. This node can be used to isolate transformations to light sources or objects
 CVrml_TranslationDefines a Translation of VRML specifying transform properties. This node defines a translation by 3D vector. By default : myTranslation (0,0,0)
 CVrml_WWWAnchorDefines a WWWAnchor node of VRML specifying group properties. The WWWAnchor group node loads a new scene into a VRML browser when one of its children is closen. Exactly how a user "chooses" a child of the WWWAnchor is up to the VRML browser. WWWAnchor with an empty ("") name does nothing when its children are chosen. WWWAnchor behaves like a Separator, pushing the traversal state before traversing its children and popping it afterwards
 CVrml_WWWInlineDefines a WWWInline node of VRML specifying group properties. The WWWInline group node reads its children from anywhere in the World Wide Web. Exactly when its children are read is not defined; reading the children may be delayed until the WWWInline is actually displayed. WWWInline with an empty ("") name does nothing. WWWInline behaves like a Separator, pushing the traversal state before traversing its children and popping it afterwards. By defaults: myName ("") myBboxSize (0,0,0) myBboxCenter (0,0,0)
