Public Member Functions

 GraphicsImpl ()=default
 Construct.
 
const SDL_GLContext & GetGLContext ()
 Return the GL Context.
 

Private Attributes

SDL_GLContext context_ {}
 SDL OpenGL context.
 
unsigned systemFBO_ {}
 iOS/tvOS system framebuffer handle.
 
unsigned activeTexture_ {}
 Active texture unit.
 
unsigned enabledVertexAttributes_ {}
 Enabled vertex attributes bitmask.
 
unsigned usedVertexAttributes_ {}
 Vertex attributes bitmask used by the current shader program.
 
unsigned instancingVertexAttributes_ {}
 Vertex attribute instancing bitmask for keeping track of divisors.
 
const HashMap< Pair< unsigned
char, unsigned char >
, unsigned > * 
vertexAttributes_ {}
 Current mapping of vertex attribute locations by semantic. The map is owned by the shader program, so care must be taken to switch a null shader program when it's destroyed.
 
unsigned boundFBO_ {}
 Currently bound frame buffer object.
 
unsigned boundVBO_ {}
 Currently bound vertex buffer object.
 
unsigned boundUBO_ {}
 Currently bound uniform buffer object.
 
unsigned resolveSrcFBO_ {}
 Read frame buffer for multisampled texture resolves.
 
unsigned resolveDestFBO_ {}
 Write frame buffer for multisampled texture resolves.
 
int pixelFormat_ {}
 Current pixel format.
 
HashMap< unsigned long long,
FrameBufferObject
frameBuffers_
 Map for FBO's per resolution and format.
 
unsigned textureTypes_ [MAX_TEXTURE_UNITS] {}
 OpenGL texture types in use.
 
ConstantBufferMap allConstantBuffers_
 Constant buffer search map.
 
ConstantBufferconstantBuffers_ [MAX_SHADER_PARAMETER_GROUPS *2] {}
 Currently bound constant buffers.
 
PODVector< ConstantBuffer * > dirtyConstantBuffers_
 Dirty constant buffers.
 
unsigned lastInstanceOffset_ {}
 Last used instance data offset.
 
HashMap< unsigned, SharedPtr
< Texture2D > > 
depthTextures_
 Map for additional depth textures, to emulate Direct3D9 ability to mix render texture and backbuffer rendering.
 
ShaderProgramshaderProgram_ {}
 Shader program in use.
 
ShaderProgramMap shaderPrograms_
 Linked shader programs.
 
bool fboDirty_ {}
 Need FBO commit flag.
 
bool vertexBuffersDirty_ {}
 Need vertex attribute pointer update flag.
 
bool sRGBWrite_ {}
 sRGB write mode flag.
