Here is a screenshot of the different transparency modes used in a single scene\&. .PP .PP Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2\&.1 API\&. .PP \fBFILE FORMAT/DEFAULTS:\fP .PP .nf TransparencyType { value SCREEN_DOOR } .fi .PP .PP \fBSee also:\fP .RS 4 \fBSoGLRenderAction::TransparencyType\fP .RE .PP \fBSince:\fP .RS 4 Coin 2\&.0 .RE .PP .SH "Member Enumeration Documentation" .PP .SS "enum \fBSoTransparencyType::Type\fP" Enumeration of available transparency types\&. See documentation in \fBSoGLRenderAction\fP for a description of the different types\&. .SH "Constructor & Destructor Documentation" .PP .SS "SoTransparencyType::SoTransparencyType (void)" Constructor\&. .SS "SoTransparencyType::~SoTransparencyType ()\fC [protected]\fP, \fC [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "\fBSoType\fP SoTransparencyType::getTypeId (void) const\fC [virtual]\fP" .PP Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example: .PP .PP .nf void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } } .fi .PP .PP For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP subclasses\&. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&. .PP For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups\&. .PP Implements \fBSoBase\fP\&. .SS "const \fBSoFieldData\fP * SoTransparencyType::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP" Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. .PP Reimplemented from \fBSoFieldContainer\fP\&. .SS "void SoTransparencyType::doAction (\fBSoAction\fP *action)\fC [virtual]\fP" This function performs the typical operation of a node for any action\&. .PP Reimplemented from \fBSoNode\fP\&. .SS "void SoTransparencyType::GLRender (\fBSoGLRenderAction\fP *action)\fC [virtual]\fP" Action method for the \fBSoGLRenderAction\fP\&. .PP This is called during rendering traversals\&. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method\&. .PP Reimplemented from \fBSoNode\fP\&. .SS "void SoTransparencyType::callback (\fBSoCallbackAction\fP *action)\fC [virtual]\fP" Action method for \fBSoCallbackAction\fP\&. .PP Simply updates the state according to how the node behaves for the render action, so the application programmer can use the \fBSoCallbackAction\fP for extracting information about the scene graph\&. .PP Reimplemented from \fBSoNode\fP\&. .SH "Member Data Documentation" .PP .SS "\fBSoSFEnum\fP SoTransparencyType::value" The transparency type to use for subsequent shape nodes in the scene graph\&. .SH "Author" .PP Generated automatically by Doxygen for Coin from the source code\&.
