enum SoHeightMapToNormalMap::NormalMapFormat¶

Enumeration of available normal map formats.

Enumerator

INT8

Encode the normals as a 3 component byte texture. This is the only option for now, as long as float textures are not conveniently supported in Coin.

SoHeightMapToNormalMap::SoHeightMapToNormalMap (void)¶

Constructor.

SoType SoHeightMapToNormalMap::getTypeId (void) const [virtual]¶

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example:

void foo(SoNode * node)
{


  if (node->getTypeId() == SoFile::getClassTypeId()) {


    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type


  }
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all 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 Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoTexture2Convert.

const SoFieldData * SoHeightMapToNormalMap::getFieldData (void) const [virtual]¶

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoTexture2Convert.

const SoEngineOutputData * SoHeightMapToNormalMap::getOutputData (void) const [virtual]¶

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Reimplemented from SoTexture2Convert.

void SoHeightMapToNormalMap::initClass (void) [static]¶

Class initializer.

void SoHeightMapToNormalMap::convert (const unsigned char * srcptr, SbVec2s size, int nc, SbImage & dst_out) [static]¶

Static function for computing a normal map from a height map. This function can be used directly without any engine instantiation.

void SoHeightMapToNormalMap::inputChanged (SoField * which) [protected], [virtual]¶

Called when an input is changed. The default method does nothing, but subclasses may override this method to do The Right Thing when a specific field is changed.

Reimplemented from SoEngine.

void SoHeightMapToNormalMap::evaluate (void) [protected], [virtual]¶

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoEngine.

SoMFEnum SoHeightMapToNormalMap::format¶

This setting decides what kind of normal map is generated. For now, only the INT8 format is available, and it is the default value.
