CEGUI::OpenGLTextureTarget::isImageryCache
bool isImageryCache() const
Return whether the RenderTarget is an implementation that caches actual rendered imagery.
CEGUI::OpenGLTextureTarget::OpenGLTextureTarget
OpenGLTextureTarget(OpenGLRendererBase &owner)
constructor.
CEGUI::OpenGLTextureTarget::createCEGUITexture
void createCEGUITexture()
helper to create CEGUI::Texture d_CEGUITexture;
CEGUI::OpenGLTextureTarget::d_texture
GLuint d_texture
Associated OpenGL texture ID.
Definition: RendererModules/OpenGL/TextureTarget.h:86
CEGUI::OpenGLRenderTarget
Intermediate OpenGL implementation of a RenderTarget.
Definition: RendererModules/OpenGL/RenderTarget.h:47
CEGUI
Main namespace for Crazy Eddie's GUI Library.
Definition: arch_overview.dox:1
CEGUI::OpenGLTexture
Texture implementation for the OpenGLRenderer.
Definition: RendererModules/OpenGL/Texture.h:45
CEGUI::OpenGLTextureTarget
OpenGLTextureTarget - Common base class for all OpenGL render targets based on some form of RTT suppo...
Definition: RendererModules/OpenGL/TextureTarget.h:47
CEGUI::OpenGLTextureTarget::isRenderingInverted
bool isRenderingInverted() const
Return whether rendering done on the target texture is inverted in relation to regular textures.
CEGUI::OpenGLTextureTarget::generateTextureName
static String generateTextureName()
helper to generate unique texture names
CEGUI::OpenGLTextureTarget::restoreTexture
virtual void restoreTexture()
Restore the texture from the locally buffered copy previously create by a call to grabTexture.
CEGUI::OpenGLTextureTarget::~OpenGLTextureTarget
virtual ~OpenGLTextureTarget()
destructor
CEGUI::OpenGLTextureTarget::s_textureNumber
static uint s_textureNumber
static data used for creating texture names
Definition: RendererModules/OpenGL/TextureTarget.h:80
CEGUI::Texture
Abstract base class specifying the required interface for Texture objects.
Definition: Texture.h:54
CEGUI::OpenGLTextureTarget::getTexture
Texture & getTexture() const
Return a pointer to the CEGUI::Texture that the TextureTarget is using.
CEGUI::OpenGLTextureTarget::d_CEGUITexture
OpenGLTexture * d_CEGUITexture
we use this to wrap d_texture so it can be used by the core CEGUI lib.
Definition: RendererModules/OpenGL/TextureTarget.h:88
CEGUI::String
String class used within the GUI system.
Definition: String.h:64
CEGUI::OpenGLRendererBase
Common base class used for other OpenGL (desktop or ES) based renderer modules.
Definition: RendererBase.h:54
CEGUI::OpenGLTextureTarget::grabTexture
virtual void grabTexture()
Grab the texture to a local buffer.
