The \fBSoShapeHints\fP node is used to set up clues to the rendering subsystem about how particular aspects of the subsequent geometry in the scene graph should be drawn\&. .PP Here is an example on how to display a scene in wireframe mode which only shows the triangles facing towards the camera\&. .PP .PP .nf #include #include #include #include #include #include #include int main(int, char * argv[]) { HWND window = SoWin::init(argv[0]); SoSeparator * root = new SoSeparator; // wireframe SoDrawStyle * drawStyle = new SoDrawStyle; drawStyle\->style = SoDrawStyle::LINES; root\->addChild(drawStyle); // back\-face culling SoShapeHints * shapeHints = new SoShapeHints; shapeHints\->vertexOrdering = SoShapeHints::COUNTERCLOCKWISE; shapeHints\->shapeType = SoShapeHints::SOLID; root\->addChild(shapeHints); // keep a solid color SoLightModel * lightModel = new SoLightModel; lightModel\->model = SoLightModel::BASE_COLOR; root\->addChild(lightModel); // a cone SoCone * cone = new SoCone; root\->addChild(cone); // set up a window SoWinExaminerViewer * viewer = new SoWinExaminerViewer(window); SbViewportRegion vpRegion = viewer\->getViewportRegion(); viewer\->setSceneGraph(root); viewer\->show(); SoWin::mainLoop(); delete viewer; return 0; } .fi .PP .PP The default settings of the rendering system are tuned towards programmer convenience\&. For instance, the default is to render both sides of all polygons to make sure we avoid any 'holes' in the geometry if the vertex ordering should happen to differ for different polygons\&. .PP If the programmer gives up some of this convenience and uses \fBSoShapeHints\fP nodes to more closely specify information about the scene graph geometry, the clues given by the \fBSoShapeHints\fP node(s) will then be used by the rendering subsystem to avoid certain costly operations\&. Significant gains in rendering speed could be seen as a result\&. .PP Be aware that the way backface culling and two-sided lighting is decided by the rendering system is not at all intuitive\&. Here are the common rules of how primitive shapes will render themselves with regard to how the \fBSoShapeHints::vertexOrdering\fP and \fBSoShapeHints::shapeType\fP fields are set: .PP .PD 0 .IP "\(bu" 2 vertexOrdering == CLOCKWISE or COUNTERCLOCKWISE, shapeType == SOLID: causes primitives to be backface culled and rendered with one-sided lighting\&. .PP .IP "\(bu" 2 vertexOrdering == CLOCKWISE or COUNTERCLOCKWISE, shapeType == UNKNOWN_SHAPE_TYPE: primitives are \fInot\fP backface culled, and they are rendered with two-sided lighting\&. .PP .IP "\(bu" 2 vertexOrdering == UNKNOWN_ORDERING, any shapeType: primitives are \fInot\fP backface culled, and they are rendered with one-sided lighting\&. The OpenGL vertex ordering will be set to counterclockwise ordering\&. .PP .PP The UNKNOWN_ORDERING enum has a special and non-intuitive meaning\&. The ordering is really set to counterclockwise -- in OpenGL and when generating normals\&. However, if you want to render your geometry with one-sided lighting and backface culling disabled, you have to use this enum value, and your polygons need to be in counterclockwise ordering\&. .PP \fBFILE FORMAT/DEFAULTS:\fP .PP .nf ShapeHints { vertexOrdering UNKNOWN_ORDERING shapeType UNKNOWN_SHAPE_TYPE faceType CONVEX creaseAngle 0 } .fi .PP .SH "Member Enumeration Documentation" .PP .SS "\fBenum\fP \fBSoShapeHints::VertexOrdering\fP" Enumeration of available ways to specify ordering of vertices for a polygon\&. .PP \fBEnumerator\fP .in +1c .TP \fB\fIUNKNOWN_ORDERING \fP\fP Ordering not known, render both sides of the polygon\&. .TP \fB\fICLOCKWISE \fP\fP Vertices are specified in a clockwise order\&. .TP \fB\fICOUNTERCLOCKWISE \fP\fP Vertices are specified in a counterclockwise order\&. .SS "\fBenum\fP \fBSoShapeHints::ShapeType\fP" Enumeration of different shape types\&. .PP \fBEnumerator\fP .in +1c .TP \fB\fIUNKNOWN_SHAPE_TYPE \fP\fP Nothing known about the shape, be conservative when rendering\&. .TP \fB\fISOLID \fP\fP The subsequent shapes in the graph are all known to be completely 'closed', solid 3D shapes\&. Backface culling will be done if vertexOrdering is known\&. .SS "\fBenum\fP \fBSoShapeHints::FaceType\fP" Enumeration of polygon face types\&. .PP \fBEnumerator\fP .in +1c .TP \fB\fIUNKNOWN_FACE_TYPE \fP\fP Signifies: nothing is known about subsequent polygon data, be conservative when rendering\&. .PP All polygons in the scene will be analyzed to see if they need to be tessellated (broken up) into triangles before passed on to the underlying immediate mode rendering system\&. .PP The OpenGL rendering system handles most complex polygon types, but not all: it can for instance have problems with many-sided, concave polygons (concave polygons are 'hollow', that is: rounded inwards)\&. Coin's internal tessellator will most often handle the cases that OpenGL fails on\&. .PP So if you are seeing weird artifacts in how complex polygons are rendered, try to change the \fBSoShapeHints::faceType\fP field to this value and see if they are then rendered correctly\&. .PP Beware that turning on this functionality might have the effect of making the rendering performance worse\&. If it has a noticeable effect on your particular scene graph, we advise that you investigate whether you could change how the polygons are generated for Coin rendering and then avoid using this flag\&. .TP \fB\fICONVEX \fP\fP Subsequent faces are all convex, so turn off the check for and tessellation of not convex faces\&. .PP Subsequent polygons from faceset-type nodes (like \fBSoFaceSet\fP and \fBSoIndexedFaceSet\fP) will be sent unmodified to OpenGL, thereby assuming that the polygons are in a form handled by OpenGL\&. .SS "\fBenum\fP \fBSoShapeHints::WindingType\fP" Enumeration of different winding types\&. .PP \fBEnumerator\fP .in +1c .TP \fB\fINO_WINDING_TYPE \fP\fP Draw without holes\&. .SH "Constructor & Destructor Documentation" .PP .SS "SoShapeHints::SoShapeHints (\fBvoid\fP)" Constructor\&. .SS "SoShapeHints::~SoShapeHints ()\fC [protected]\fP, \fC [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "\fBSoType\fP SoShapeHints::getClassTypeId (\fBvoid\fP)\fC [static]\fP" This static method returns the \fBSoType\fP object associated with objects of this class\&. .br .SS "\fBSoType\fP SoShapeHints::getTypeId (\fBvoid\fP) const\fC [virtual]\fP" Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&.
