class GraphicCore

Graphic core interface.

Provides core graphics functionality and resource management.

Subclassed by RaeptorCogs::GAPI::GL::GraphicCore, RaeptorCogs::GAPI::Vulkan::GraphicCore

Public Functions

inline GraphicCore(RendererBackend &renderer)

Default constructor.

Initializes the GraphicCore.

virtual ~GraphicCore() = default

Virtual destructor.

Cleans up resources used by the GraphicCore.

void updateGraphicGPUData()

Update the GPU data for graphics.

Note

Uploads instance data and order indices to the GPU.

inline InstanceData &getInstanceData()

Get the instance data.

Returns:

Reference to the instance data.

inline InstanceAllocator &getInstanceAllocator()

Get the instance allocator.

Returns:

Reference to the instance allocator.

inline InstanceUploader &getInstanceUploader()

Get the instance uploader.

Returns:

Reference to the instance uploader.

ObjectHandler<SSBO> &getStaticInstanceDataSSBO()

Get the static instance data SSBO.

Returns:

Reference to the static instance data SSBO.

ObjectHandler<SSBO> &getDynamicInstanceDataSSBO()

Get the dynamic instance data SSBO.

Returns:

Reference to the dynamic instance data SSBO.

ObjectHandler<VBO> &getQuadVBO()

Get the quad VBO.

Returns:

Reference to the quad VBO.

ObjectHandler<EBO> &getQuadEBO()

Get the quad EBO.

Returns:

Reference to the quad EBO.

virtual void setViewport(int x, int y, int width, int height) = 0

Set the viewport dimensions.

Note

Configures the rendering viewport.

Parameters:

• x – X position of the viewport.

• y – Y position of the viewport.

• width – Width of the viewport.

• height – Height of the viewport.

virtual void clearSwapchainBuffers() = 0

Clear the swapchain buffers.

Note

Clears color, depth, and stencil buffers.

virtual void useBlend() = 0

Use blending for rendering.

Note

Enables blending state in the graphics pipeline.

virtual void bindMaskTexture() = 0

Bind the mask texture.

Note

Binds the mask texture to the appropriate texture unit.

virtual void setTextureUniform(ObjectHandler<Common::Shader> shader) = 0

Set the texture uniform in shaders.

Note

Updates the shader uniform for the main texture.

virtual void setMaskTextureUniform(ObjectHandler<Common::Shader> shader) = 0

Set the mask texture uniform in shaders.

Note

Updates the shader uniform for the mask texture.

virtual void drawElementsInstancedBaseVertexBaseInstance(size_t count, size_t instanceCount, size_t first, int baseVertex, unsigned int baseInstance) = 0

Draw elements with instancing, base vertex, and base instance.

Note

Issues a draw call with advanced parameters.

Parameters:

• count – Number of elements to draw.

• instanceCount – Number of instances to draw.

• first – Index of the first element to draw.

• baseVertex – Base vertex offset.

• baseInstance – Base instance offset.

virtual void bindGraphicTexture(Graphic2D &graphic) = 0

Bind a graphic texture for rendering.

Note

Binds the specified texture for use in rendering.

Parameters:

graphic – Graphic to bind.

virtual void enableStencilGuarding() = 0

Enable stencil guarding.

Note

Activates stencil buffer operations for guarding.
