## Detailed Description

Defines a program which runs on the GPU such as a vertex or fragment program.

Remarks:
  This class defines the low-level program in assembler code, the sort used to directly assemble into machine instructions for the GPU to execute. By nature, this means that the assembler source is rendersystem specific, which is why this is an abstract class - real instances are created through the RenderSystem. If you wish to use higher level shading languages like HLSL and Cg, you need to use the HighLevelGpuProgram class instead.

## Member Function Documentation

virtual GpuProgram* Ogre::GpuProgram::_getBindingDelegate | ( | void |  | ) | `[virtual]`

Returns the GpuProgram which should be bound to the pipeline.

Remarks:
  This method is simply to allow some subclasses of GpuProgram to delegate the program which is bound to the pipeline to a delegate, if required.

Reimplemented in Ogre::HighLevelGpuProgram, and Ogre::UnifiedHighLevelGpuProgram.

Definition at line 1444 of file OgreGpuProgram.h.

void Ogre::Resource::_notifyOrigin | ( | const String & | origin | ) | `[inherited]`

| Notify this resource of it's origin. Definition at line 357 of file OgreResource.h.

void Ogre::Resource::addListener | ( | Listener * | lis | ) | `[inherited]`

Register a listener on this resource.

See also:
  Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

size_t Ogre::GpuProgram::calculateSize | ( | void |  | ) | const`[protected, virtual]`

| Implements Ogre::Resource. Definition at line 1402 of file OgreGpuProgram.h.

void Ogre::Resource::changeGroupOwnership | ( | const String & | newGroup | ) | `[inherited]`

Change the resource group ownership of a Resource.

Remarks:
  This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.

Parameters:

  | newGroup | Name of the new group

static void Ogre::StringInterface::cleanupDictionary | ( |  | ) | `[static, inherited]`

| Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g. MaterialManager) initializes.

virtual void Ogre::StringInterface::copyParametersTo | ( | StringInterface * | dest | ) | const`[virtual, inherited]`

Method for copying this object's parameters to another object.

Remarks:
  This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

  Any unrecognised parameters will be ignored as with setParameter method.

Parameters:

  | dest | Pointer to object to have it's parameters set the same as this object.

Definition at line 300 of file OgreStringInterface.h.

References Ogre::ParamDictionary::mParamDefs.

bool Ogre::StringInterface::createParamDictionary | ( | const String & | className | ) | `[protected, inherited]`

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks:
  This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).

Parameters:

  | className | the name of the class using the dictionary

Returns:
  true if a new dictionary was created, false if it was already there

Definition at line 176 of file OgreStringInterface.h.

virtual GpuProgramParametersSharedPtr Ogre::GpuProgram::createParameters | ( | void |  | ) | `[virtual]`

Creates a new parameters object compatible with this program definition.

Remarks:
  It is recommended that you use this method of creating parameters objects rather than going direct to GpuProgramManager, because this method will populate any implementation-specific extras (like named parameters) where they are appropriate.

Reimplemented in Ogre::HighLevelGpuProgram, and Ogre::UnifiedHighLevelGpuProgram.

void Ogre::Resource::escalateLoading | ( |  | ) | `[inherited]`

Escalates the loading of a background loaded resource.

Remarks:
  If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

ResourceManager* Ogre::Resource::getCreator | ( | void |  | ) | `[inherited]`

| Gets the manager which created this resource. Definition at line 348 of file OgreResource.h.

virtual GpuProgramParametersSharedPtr Ogre::GpuProgram::getDefaultParameters | ( | void |  | ) | `[virtual]`

Get a reference to the default parameters which are to be used for all uses of this program.

Remarks:
  A program can be set up with a list of default parameters, which can save time when using a program many times in a material with roughly the same settings. By retrieving the default parameters and populating it with the most used options, any new parameter objects created from this program afterwards will automatically include the default parameters; thus users of the program need only change the parameters which are unique to their own usage of the program.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

const String& Ogre::Resource::getGroup | ( | void |  | ) | `[inherited]`

| Gets the group which this resource is a member of. Reimplemented in Ogre::SkeletonInstance. Definition at line 336 of file OgreResource.h.

const String& Ogre::Resource::getOrigin | ( | void |  | ) | const`[inherited]`

Get the origin of this resource, e.g.

a script file name.

Remarks:
  This property will only contain something if the creator of this resource chose to populate it. Script loaders are advised to populate it.

Definition at line 355 of file OgreResource.h.

const ParamDictionary* Ogre::StringInterface::getParamDictionary | ( | void |  | ) | const`[inherited]`

| Definition at line 213 of file OgreStringInterface.h.

ParamDictionary* Ogre::StringInterface::getParamDictionary | ( | void |  | ) | `[inherited]`

Retrieves the parameter dictionary for this class.

Remarks:
  Only valid to call this after createParamDictionary.

Returns:

Definition at line 200 of file OgreStringInterface.h.

virtual String Ogre::StringInterface::getParameter | ( | const String & | name | ) | const`[virtual, inherited]`

Generic parameter retrieval method.

Remarks:
  Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.

Parameters:

  | name | The name of the parameter to get

Returns:
  String value of parameter, blank if not found

Definition at line 269 of file OgreStringInterface.h.

References Ogre::ParamCommand::doGet(), and Ogre::ParamDictionary::getParamCommand().

virtual bool Ogre::GpuProgram::hasDefaultParameters | ( | void |  | ) | const`[virtual]`

| Returns true if default parameters have been set up. Reimplemented in Ogre::UnifiedHighLevelGpuProgram. Definition at line 1536 of file OgreGpuProgram.h.

bool Ogre::Resource::isBackgroundLoaded | ( | void |  | ) | const`[inherited]`

Returns whether this Resource has been earmarked for background loading.

Remarks:
  This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Remarks:
  If this returns true, OGRE will not blend the geometry according to morph animation, it will expect the vertex program to do it.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 1500 of file OgreGpuProgram.h.

virtual bool Ogre::GpuProgram::isPoseAnimationIncluded | ( | void |  | ) | const`[virtual]`

virtual void Ogre::Resource::load | ( | bool | backgroundThread = `false` | ) | `[virtual, inherited]`

Loads the resource, if it is not already.

Remarks:
  If the resource is loaded from a file, loading is automatic. If not, if for example this resource gained it's data from procedural calls rather than loading from a file, then this resource will not reload on it's own.

Remarks:

See also:
  Resource::isBackgroundLoaded . Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

virtual void Ogre::GpuProgram::setSkeletalAnimationIncluded | ( | bool | included | ) | `[virtual]`

Sets whether a vertex program includes the required instructions to perform skeletal animation.

Remarks:
  If this is set to true, OGRE will not blend the geometry according to skeletal animation, it will expect the vertex program to do it.

Definition at line 1464 of file OgreGpuProgram.h.

virtual void Ogre::GpuProgram::setSource | ( | const String & | source | ) | `[virtual]`

Sets the source assembly for this program from an in-memory string.

Remarks:
  Setting this will have no effect until you (re)load the program.

virtual void Ogre::GpuProgram::setSourceFile | ( | const String & | filename | ) | `[virtual]`

Sets the filename of the source assembly for this program.

Remarks:
  Setting this will have no effect until you (re)load the program.

virtual void Ogre::GpuProgram::setSurfaceAndPassLightStates | ( | bool | state | ) | `[virtual]`

Sets whether a vertex program requires light and material states to be passed to through fixed pipeline low level API rendering calls.

Remarks:
  If this is set to true, OGRE will pass all active light states to the fixed function pipeline. This is useful for high level shaders like GLSL that can read the OpenGL light and material states. This way the user does not have to use autoparameters to pass light position, color etc.

Definition at line 1546 of file OgreGpuProgram.h.

virtual void Ogre::GpuProgram::setSyntaxCode | ( | const String & | syntax | ) | `[virtual]`

| Sets the syntax code for this program e.g. arbvp1, fp20, vs_1_1 etc

virtual void Ogre::GpuProgram::setType | ( | GpuProgramType | t | ) | `[virtual]`

| Set the program type (only valid before load).

void Ogre::GpuProgram::setupBaseParamDictionary | ( | void |  | ) | `[protected]`

Internal method for setting up the basic parameter definitions for a subclass.

Remarks:
  Because StringInterface holds a dictionary of parameters per class, subclasses need to call this to ask the base class to add it's parameters to their dictionary as well. Can't do this in the constructor because that runs in a non-virtual context.

  The subclass must have called it's own createParamDictionary before calling this method.

virtual void Ogre::GpuProgram::setVertexTextureFetchRequired | ( | bool | r | ) | `[virtual]`

| Sets whether this vertex program requires support for vertex texture fetch from the hardware. Definition at line 1516 of file OgreGpuProgram.h.

virtual void Ogre::Resource::touch | ( | void |  | ) | `[virtual, inherited]`

| 'Touches' the resource to indicate it has been used. Reimplemented in Ogre::Material, and Ogre::UnifiedHighLevelGpuProgram.

virtual void Ogre::Resource::unload | ( | void |  | ) | `[virtual, inherited]`

| Unloads the resource; this is not permanent, the resource can be reloaded later if required. Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

virtual void Ogre::Resource::unloadImpl | ( | void |  | ) | `[protected, pure virtual, inherited]`

| Internal implementation of the 'unload' action; called regardless of whether this resource is being loaded from a ManualResourceLoader. Implemented in Ogre::Compositor, Ogre::Font, Ogre::HighLevelGpuProgram, Ogre::Material, Ogre::Mesh, Ogre::Skeleton, Ogre::SkeletonInstance, and Ogre::Texture.
