Member Function Documentation

◆ setConfigOption()

void Ogre::GLRenderSystemCommon::setConfigOption ( const String name,
const String value 
)
virtual

Sets an option for this API.

Remarks
Used to confirm the settings (normally chosen by the user) in order to make the renderer able to initialise with the settings as required. This may be video mode, D3D driver, full screen / windowed etc. Called automatically by the default configuration dialog, and by the restoration of saved settings. These settings are stored and only activated when RenderSystem::initialise or RenderSystem::reinitialise are called.
If using a custom configuration dialog, it is advised that the caller calls RenderSystem::getConfigOptions again, since some options can alter resulting from a selection.
Parameters
nameThe name of the option to alter.
valueThe value to set the option to.

Implements Ogre::RenderSystem.

◆ _copyContentsToMemory()

virtual void Ogre::GLRenderSystemCommon::_copyContentsToMemory ( Viewport vp,
const Box src,
const PixelBox dst,
RenderWindow::FrameBuffer  buffer 
)
pure virtual

Copies the current contents of the render target to a pixelbox.

Remarks
See suggestPixelFormat for a tip as to the best pixel format to extract into, although you can use whatever format you like and the results will be converted.

Implemented in Ogre::GLRenderSystem, and Ogre::GL3PlusRenderSystem.

◆ _getMainContext()

GLContext* Ogre::GLRenderSystemCommon::_getMainContext ( )
inline

Returns the main context.

◆ _getCurrentContext()

GLContext* Ogre::GLRenderSystemCommon::_getCurrentContext ( )
inline

Returns the current context.

◆ hasMinGLVersion()

bool Ogre::GLRenderSystemCommon::hasMinGLVersion ( int  major,
int  minor 
) const

Check if GL Version is supported.

◆ checkExtension()

bool Ogre::GLRenderSystemCommon::checkExtension ( const String ext) const

Check if an extension is available.

◆ validateConfigOptions()

String Ogre::GLRenderSystemCommon::validateConfigOptions ( )
inlinevirtual

Validates the options set for the rendering system, returning a message if there are problems.

Note
If the returned string is empty, there are no problems.

Implements Ogre::RenderSystem.

References Ogre::BLANKSTRING.

◆ _unregisterContext()

virtual void Ogre::GLRenderSystemCommon::_unregisterContext ( GLContext context)
pure virtual

Unregister a render target->context mapping.

If the context of target is the current context, change the context to the main context so it can be destroyed safely.

Note
This is automatically called by the destructor of GLContext.

Implemented in Ogre::GLRenderSystem, Ogre::GLES2RenderSystem, and Ogre::GL3PlusRenderSystem.

◆ bindVertexElementToGpu()

virtual void Ogre::GLRenderSystemCommon::bindVertexElementToGpu ( const VertexElement elem,
const HardwareVertexBufferSharedPtr vertexBuffer,
const size_t  vertexStart 
)
pure virtual

◆ getHorizontalTexelOffset()

Real Ogre::GLRenderSystemCommon::getHorizontalTexelOffset ( void  )
inlinevirtual

Returns the horizontal texel offset value required for mapping texel origins to pixel origins in this rendersystem.

Remarks
Since rendersystems sometimes disagree on the origin of a texel, mapping from texels to pixels can sometimes be problematic to implement generically. This method allows you to retrieve the offset required to map the origin of a texel to the origin of a pixel in the horizontal direction.

Implements Ogre::RenderSystem.

◆ getVerticalTexelOffset()

Real Ogre::GLRenderSystemCommon::getVerticalTexelOffset ( void  )
inlinevirtual

Returns the vertical texel offset value required for mapping texel origins to pixel origins in this rendersystem.

Remarks
Since rendersystems sometimes disagree on the origin of a texel, mapping from texels to pixels can sometimes be problematic to implement generically. This method allows you to retrieve the offset required to map the origin of a texel to the origin of a pixel in the vertical direction.

Implements Ogre::RenderSystem.

◆ getMinimumDepthInputValue()

Real Ogre::GLRenderSystemCommon::getMinimumDepthInputValue ( void  )
inlinevirtual

Gets the minimum (closest) depth value to be used when rendering using identity transforms.

Remarks
When using identity transforms you can manually set the depth of a vertex; however the input values required differ per rendersystem. This method lets you retrieve the correct value.
See also
Renderable::getUseIdentityView, Renderable::getUseIdentityProjection

Implements Ogre::RenderSystem.

◆ getMaximumDepthInputValue()

Real Ogre::GLRenderSystemCommon::getMaximumDepthInputValue ( void  )
inlinevirtual

Gets the maximum (farthest) depth value to be used when rendering using identity transforms.

Remarks
When using identity transforms you can manually set the depth of a vertex; however the input values required differ per rendersystem. This method lets you retrieve the correct value.

Implements Ogre::RenderSystem.

◆ _convertProjectionMatrix()

void Ogre::GLRenderSystemCommon::_convertProjectionMatrix ( const Matrix4 matrix,
Matrix4 dest,
bool  forGpuProgram 
)
virtual

Converts a uniform projection matrix to suitable for this render system.

Remarks
Because different APIs have different requirements (some incompatible) for the projection matrix, this method allows each to implement their own correctly and pass back a generic OGRE matrix for storage in the engine.

Implements Ogre::RenderSystem.

◆ _getDepthStencilFormatFor()

virtual void Ogre::GLRenderSystemCommon::_getDepthStencilFormatFor ( PixelFormat  internalColourFormat,
uint32 depthFormat,
uint32 stencilFormat 
)
virtual

Mimics D3D9RenderSystem::_getDepthStencilFormatFor, if no FBO RTT manager, outputs GL_NONE.

Reimplemented in Ogre::GL3PlusRenderSystem.

◆ _createVao()

virtual uint32 Ogre::GLRenderSystemCommon::_createVao ( )
inlinevirtual

Create VAO on current context.

Reimplemented in Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.

◆ _bindVao()

virtual void Ogre::GLRenderSystemCommon::_bindVao ( GLContext context,
uint32  vao 
)
inlinevirtual

Bind VAO, context should be equal to current context, as VAOs are not shared

Reimplemented in Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.

◆ _destroyVao()

virtual void Ogre::GLRenderSystemCommon::_destroyVao ( GLContext context,
uint32  vao 
)

◆ _destroyFbo()

virtual void Ogre::GLRenderSystemCommon::_destroyFbo ( GLContext context,
uint32  fbo 
)
inlinevirtual

Destroy FBO immediately or defer if it was created on other context.

Reimplemented in Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.

◆ _completeDeferredVaoFboDestruction()

void Ogre::GLRenderSystemCommon::_completeDeferredVaoFboDestruction ( )

Complete destruction of VAOs and FBOs deferred while creator context was not current.

◆ registerThread()

void Ogre::GLRenderSystemCommon::registerThread ( )
virtual

Register the an additional thread which may make calls to rendersystem-related objects.

Remarks
This method should only be called by additional threads during their initialisation. If they intend to use hardware rendering system resources they should call this method before doing anything related to the render system. Some rendering APIs require a per-thread setup and this method will sort that out. It is also necessary to call unregisterThread before the thread shuts down.
Note
This method takes no parameters - it must be called from the thread being registered and that context is enough.

Implements Ogre::RenderSystem.

◆ unregisterThread()

void Ogre::GLRenderSystemCommon::unregisterThread ( )
virtual

Unregister an additional thread which may make calls to rendersystem-related objects.

See also
RenderSystem::registerThread

Implements Ogre::RenderSystem.

◆ preExtraThreadsStarted()

void Ogre::GLRenderSystemCommon::preExtraThreadsStarted ( )
virtual

Tell the rendersystem to perform any prep tasks it needs to directly before other threads which might access the rendering API are registered.

Remarks
Call this from your main thread before starting your other threads.
Note
If you start your own threads, there is a specific startup sequence which must be respected and requires synchronisation between the threads:
  1. [Main thread] Call preExtraThreadsStarted()
  2. [Main thread] Start other thread, wait
  3. [Other thread] Call registerThread(), notify main thread & continue
  4. [Main thread] Wake up & call postExtraThreadsStarted()
Once this init sequence is completed the threads are independent but this startup sequence must be respected.

Implements Ogre::RenderSystem.

◆ postExtraThreadsStarted()

void Ogre::GLRenderSystemCommon::postExtraThreadsStarted ( )
virtual

Tell the rendersystem to perform any tasks it needs to directly after other threads which might access the rendering API are registered.
