Detailed Description

Represents the renderer of an Application.

The Renderer is responsible for rendering components to the screen. It can be extended to support different rendering backends (e.g., terminal, GUI, web).

Member Function Documentation

clear()

virtual void Renderer::clear ( void  )

inlinevirtual

Clears the rendering target.

This method is called to clear the current rendering target (e.g., the screen or a texture) before drawing new content.

draw()

virtual void Renderer::draw ( std::shared_ptr< Primitive >  primitive )

virtual

Draws a primitive to the screen.

This method dispatches to the appropriate specific draw method based on the primitive type. Derived classes can override either this method or the specific draw methods (drawText, drawRectangle, etc.).

Parameters

primitive

The primitive to render

drawPolygon()

virtual void Renderer::drawPolygon ( std::shared_ptr< Polygon >  polygon )

inlinevirtual

Draws a polygon primitive in 3D space.

This is a virtual method that can be overridden by derived classes to implement specific 3D polygon rendering logic for different backends. The polygon includes surface normal calculation and centroid computation.

Parameters

polygon

The polygon primitive to render in 3D space

drawRectangle()

virtual void Renderer::drawRectangle ( std::shared_ptr< Rectangle >  rectangle )

inlinevirtual

Draws a rectangle primitive in 3D space.

This is a virtual method that can be overridden by derived classes to implement specific 3D rectangle rendering logic for different backends. The rectangle maintains full 3D positioning for all corners.

Parameters

rectangle

The rectangle primitive to render in 3D space

drawText()

virtual void Renderer::drawText ( std::shared_ptr< Text >  text )

inlinevirtual

Draws a text primitive in 3D space.

This is a virtual method that can be overridden by derived classes to implement specific 3D text rendering logic for different backends. The text includes 3D position, rotation, and scale information.

Parameters

text	The text primitive to render in 3D space

drawTriangle()

virtual void Renderer::drawTriangle ( std::shared_ptr< Triangle >  triangle )

inlinevirtual

Draws a triangle primitive in 3D space.

This is a virtual method that can be overridden by derived classes to implement specific 3D triangle rendering logic for different backends. The triangle includes surface normal calculation and area computation.

Parameters

triangle

The triangle primitive to render in 3D space

present()

virtual void Renderer::present ( void  )

inlinevirtual

Presents the rendered content to the display.

This method is called after all drawing commands have been issued to present the final rendered content to the screen.
