Detailed Description

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


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

Member Enumeration Documentation

enum sglShadeModel::ShadeModelEnum

The shade model type tokens.

Enumeration values:
eFLAT   flat shading.
eSMOOTH   smooth (or Gouraud) shading.

Definition at line 2099 of file sglStatelet.hpp.

Constructor & Destructor Documentation

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

Constructor (also the default constructor)

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.

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.

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.

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.

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.
