Member Function Documentation

cleanUp

void SimpleTexturedRenderer::cleanUp ( )

overrideslot

Cleans up all OpenGL data. This assumes that the correct context is current, and all data is cleaned immediately. Locks the mGLDataMutex.

Here is the call graph for this function:

clearAll

void SimpleTexturedRenderer::clearAll ( )

slot

Clears all OpenGL data, not assuming that a context is current. Some data may not be cleared immediately. Locks the mGLDataMutex.

Here is the caller graph for this function:

create()

void SimpleTexturedRenderer::create ( )

overridevirtual

This is (should be) called on an OpenGL thread before this object is used. Allows the renderer to initialize its OpenGL-dependent objects.

The difference between this and initializeGL() is that this should only include lightweight initialization.

Reimplemented from AbstractRenderer.

Here is the call graph for this function:

initializeRenderer()

void SimpleTexturedRenderer::initializeRenderer ( )

overrideprotectedvirtual

Used to initialize renderer parameters that require an OpenGL context to be bound.

Implements AbstractRenderer.

Here is the call graph for this function:

objectAdded

void SimpleTexturedRenderer::objectAdded ( const SimpleTexturedObject &  obj )

slot

This slot should be called whenever the underlying scene has a new object.

Parameters

obj	The new object.

Here is the caller graph for this function:

objectRemoved

void SimpleTexturedRenderer::objectRemoved ( const SimpleTexturedObject &  obj )

slot

This slot should be called whenever an object is removed from the underlying scene. Locks the mGLDataMutex.

Parameters

obj	The object that is already removed or will be removed.

Here is the call graph for this function:

Here is the caller graph for this function:

paint()

void SimpleTexturedRenderer::paint ( QMatrix4x4  mvpMatrix, QVector3D  camPos  )

overridevirtual

Uses OpenGL commands to draw to the frame buffer. Nothing is assumed about the previous contents of the frame (i.e. glClear does not need to be called before this), and the OpenGL state should not change as a result of calling this function.

It is assumed that initializeGL() has been called for the current OpenGL context.

Parameters

vpMatrix	The model-view-projection matrix that should be used.
camPos	The world-space coordinates of the camera.

Implements AbstractRenderer.

Here is the call graph for this function:
