eu.svjatoslav.sixth.e3d.renderer.raster.shapes.basic.solidpolygon.SolidPolygon

public class SolidPolygon
extends AbstractCoordinateShape

A solid-color triangle renderer with mouse interaction support.

This class implements a high-performance triangle rasterizer using scanline algorithms. It handles: - Perspective-correct edge interpolation - Alpha blending with background pixels - Viewport clipping - Mouse hover detection via point-in-polygon tests - Optional flat shading based on light sources

The static drawPolygon method is designed for reuse by other polygon types.

getLightingManager

public LightingManager getLightingManager()

Returns the lighting manager used for shading calculations.

Returns:

the lighting manager, or null if shading is not enabled

isShadingEnabled

public boolean isShadingEnabled()

Checks if shading is enabled for this polygon.

Returns:

true if shading is enabled, false otherwise

setShadingEnabled

public void setShadingEnabled(boolean shadingEnabled,
 LightingManager lightingManager)

Enables or disables shading for this polygon.

Parameters:

shadingEnabled - true to enable shading, false to disable

lightingManager - the lighting manager to use for shading calculations

isBackfaceCullingEnabled

public boolean isBackfaceCullingEnabled()

setBackfaceCulling

public void setBackfaceCulling(boolean backfaceCulling)

paint

public void paint(RenderingContext renderBuffer)

Description copied from class: AbstractCoordinateShape

Paints this shape onto the rendering context's pixel buffer.

This method is called after all shapes have been transformed and sorted by depth. Implementations should use the transformed screen-space coordinates from Vertex.transformedCoordinate to draw pixels.

Specified by:

paint in class AbstractCoordinateShape

Parameters:

renderBuffer - the rendering context containing the pixel buffer and graphics context
