Detailed Description

This statelet encapsulates OpenGL's glShadeModel() function which sets the shading model to either flat or smooth (the default).

Example:

   sglShadeModel *shade_model = new sglShadeModel;    // default: smooth
   shade_model->setShadeModel(sglShadeModel::eFLAT);  // flat shading

Constructor & Destructor Documentation

sglShadeModel::sglShadeModel ( ShadeModelEnum model = eSMOOTH ) [inline]

Constructor (also the default constructor) Parameters: model   One of the ShadeModelEnum tokens: eFLAT for flat shading, or eSMOOTH (the default) for Gouraud shading. Definition at line 2113 of file sglStatelet.hpp.

sglShadeModel::~sglShadeModel ( ) [inline, virtual]

virtual destructor. Definition at line 2117 of file sglStatelet.hpp.

Member Function Documentation

void sglShadeModel::setShadeModel ( ShadeModelEnum model ) [inline]

Set the shading model. Parameters: model   One of the ShadeModelEnum tokens: eFLAT for flat shading, or eSMOOTH for Gouraud shading. Definition at line 2123 of file sglStatelet.hpp.

ShadeModelEnum sglShadeModel::getShadeModel ( ) const [inline]

Query the current shading model. Returns: One of the ShadeModelEnum tokens corresponding to the current shading model. Definition at line 2129 of file sglStatelet.hpp.

void sglShadeModel::apply ( sglCurrState * curr_state ) const [virtual]

Apply this state change to the current rendering state. Parameters: curr_state   Required for statelets that affect one another. For example the sglTransparency sets up depth mask and blending modes which interact with the sglBlending and sglDepthMask statelets, and the curr_state object is used to resolve these internal issues. Reimplemented from sglStatelet.

virtual void sglShadeModel::printInfo ( ostream & ostrm, const char * indent_string ) const [virtual]

Output the state of this node to the specified ostream. Parameters: ostrm   the ostream to which the output is sent indent_string   the string (usually spaces) that is output at the beginning of every line of output Reimplemented from sglStatelet.
