The SoNormalBundle class simplifies normal handling.
This class is currently not used in Coin but is provided for API compatibility.
SoNormalBundle::SoNormalBundle | ( | SoAction * | action, |
SbBool | forrendering | ||
) |
Constructor.
SoNormalBundle::~SoNormalBundle | ( | ) |
Destructor.
SbBool SoNormalBundle::shouldGenerate | ( | int | numneeded | ) |
Returns FALSE if there are normals on the state. Otherwise initGenerator() is called with numneeded as argument, and TRUE is returned.
void SoNormalBundle::initGenerator | ( | int | initnum = 100 | ) |
Initializes the normal generator. initnum is a hint that should contain the approximate number of normals to be generated.
void SoNormalBundle::beginPolygon | ( | void | ) |
Start polygon specification. Call polygonVertex() for each vertex in the polygon, and then endPolygon() to close the polygon.
void SoNormalBundle::polygonVertex | ( | const SbVec3f & | v | ) |
Call for each vertex in a polygon.
void SoNormalBundle::endPolygon | ( | void | ) |
Call to close a polygon.
Convenience method to specify a triangle. p1, p2, and p3 are the triangles vertices.
void SoNormalBundle::generate | ( | int | startindex = 0 , |
SbBool | addtostate = TRUE |
||
) |
Generate normals for the shape. startindex should always be 0 (the SoNonIndexedShape::startIndex field is obsoleted). addtostate should be true if the generated normals should be pushed onto the current state.
const SbVec3f * SoNormalBundle::getGeneratedNormals | ( | void | ) | const |
Returns the number of generated normals.
int SoNormalBundle::getNumGeneratedNormals | ( | void | ) | const |
Returns a pointer to the generated normals.
void SoNormalBundle::set | ( | int32_t | num, |
const SbVec3f * | normals | ||
) |
Can be used by nodes that generate their own normals. The state will be updated with the new normals, and the state will be popped again when the SoNormalBundle destructor is called.
void SoNormalBundle::send | ( | int | index | ) | const |
Send the index'th normal to OpenGL.
