Constructor & Destructor Documentation

seq::Renderer::Renderer ( Application & application )

Construct a new renderer.

Version:: 1.0

Reimplemented in eqHello::Renderer, and seqPly::Renderer.

virtual seq::Renderer::~Renderer ( ) [virtual]

Destruct this renderer.

Version:: 1.0

Reimplemented in eqHello::Renderer, and seqPly::Renderer.

Member Function Documentation

virtual void seq::Renderer::applyModelMatrix ( ) [virtual]

Apply the current model matrix to OpenGL.

This method is not included in applyRenderContext() since ligthing parameters are often applied before positioning the model.

This method is only to be called from clear(), draw() and TBD.

Version:: 1.0

Referenced by eqHello::Renderer::draw(), and seqPly::Renderer::draw().

Here is the caller graph for this function:

virtual void seq::Renderer::applyRenderContext ( ) [virtual]

Apply the current rendering parameters to OpenGL.

This method sets the draw buffer, color mask, viewport as well as the projection and view matrix.

This method is only to be called from clear(), draw() and TBD.

Version:: 1.0

Referenced by eqHello::Renderer::draw(), and seqPly::Renderer::draw().

Here is the caller graph for this function:

virtual void seq::Renderer::clear ( co::Object * frameData ) [virtual]

Clear the frame buffer.

Parameters:

frameData the renderer's instance of the object passed to Config::run.

Version:: 1.0

virtual co::Object* seq::Renderer::createObject ( const uint32_t type ) [virtual]

Returns:: a new object instance of the given type.

Version:: 1.0

See also:: ObjectType, Config::getObject(), Renderer::getObject()

Implements seq::ObjectFactory.

Reimplemented in seqPly::Renderer.

virtual ViewData* seq::Renderer::createViewData ( ) [virtual]

Create a new per-view data instance.

Called once for each view used by this renderer. Creates the view instance used by the renderer to retrieve parameters from the application for rendering.

Returns:: the new view data

Version:: 1.0

virtual void seq::Renderer::destroyObject	(	co::Object *	object,
		const uint32_t	type
	)		`[virtual]`

Delete the given object of the given type.

Version:: 1.0

Reimplemented from seq::ObjectFactory.

virtual void seq::Renderer::destroyViewData ( ViewData * viewData ) [virtual]

Delete the given view data.

Version:: 1.0

virtual void seq::Renderer::draw ( co::Object * frameData ) [pure virtual]

Render the scene.

Parameters:

frameData the renderer's instance of the object passed to Config::run.

Version:: 1.0

Implemented in seqPly::Renderer, and eqHello::Renderer.

virtual bool seq::Renderer::exit ( ) [inline, virtual]

De-initialize the renderer.

Called just before the last context will be destroyed after the last call to exitContext().

Returns:: true on success, false otherwise.

Version:: 1.0

Reimplemented in seqPly::Renderer.

Definition at line 65 of file include/seq/renderer.h.

virtual bool seq::Renderer::exitContext ( ) [virtual]

De-initialize an OpenGL context.

Called just before the context will be destroyed.

Returns:: true on success, false otherwise.

Version:: 1.0

Application& seq::Renderer::getApplication ( ) [inline]

Returns:: the application instance for this renderer.

Version:: 1.0

Definition at line 136 of file include/seq/renderer.h.

Referenced by seqPly::Renderer::draw().

Here is the caller graph for this function:

const Application& seq::Renderer::getApplication ( ) const [inline]

Returns:: the application instance for this renderer.

Version:: 1.0

Definition at line 139 of file include/seq/renderer.h.

const Frustumf& seq::Renderer::getFrustum ( ) const

Returns:: the current view frustum.

Version:: 1.0

Referenced by seqPly::Renderer::draw().

Here is the caller graph for this function:

const Matrix4f& seq::Renderer::getModelMatrix ( ) const

Returns:: the current model (scene) transformation.

Version:: 1.0

Referenced by seqPly::Renderer::draw().

Here is the caller graph for this function:

const Matrix4f& seq::Renderer::getViewMatrix ( ) const

Returns:: the current view (frustum) transformation.

Version:: 1.0

Referenced by seqPly::Renderer::draw().

Here is the caller graph for this function:

const GLEWContext* seq::Renderer::glewGetContext ( ) const

Get the GLEW context for this renderer.

The glew context provides access to OpenGL extensions. This function does not follow the Sequel naming conventions, since GLEW uses a function of this name to automatically resolve OpenGL function entry points. Therefore, any OpenGL function support by the driver can be directly called from any method of an initialized renderer.
