Function Documentation

template<class VtxT >

void sp::math::Rasterizer::computeRasterScanline	(	const VtxT *(&)	v[3],
		s32	y,
		s32	yStart,
		s32	yMiddle,
		VtxT &	a,
		VtxT &	b
	)

Only used internally for the rasterizeTriangle template function.

SP_EXPORT void sp::math::Rasterizer::rasterizeCircle	(	const RenderPixelCallback &	RenderCallback,
		const dim::point2di &	Position,
		s32	Radius,
		void *	UserData = `0`
	)

Rasterizes a circle onto a 2D screen using the "Bresenham" algorithm.

Parameters:

`[in]`	RenderCallback	Specifies the pixel rendering callback. Without this callback the function renders nothing. Use this to draw a pixel onto a screen or image buffer with the given x and y coordainte.
`[in]`	Position	Specifies the 2D position of the circle.
`[in]`	Radius	Specifies the radius of the circle.
`[in]`	UserData	Any user data which will be passed to the render callback.

SP_EXPORT void sp::math::Rasterizer::rasterizeEllipse	(	const RenderPixelCallback &	RenderCallback,
		const dim::point2di &	Position,
		const dim::size2di &	Radius,
		void *	UserData = `0`
	)

Rasterizes an ellipse onto a 2D screen using the "Bresenham" algorithm.

Parameters:

`[in]`	RenderCallback	Specifies the pixel rendering callback. Without this callback the function renders nothing. Use this to draw a pixel onto a screen or image buffer with the given x and y coordainte.
`[in]`	Position	Specifies the 2D position of the ellipse.
`[in]`	Radius	Specifies the radius of the ellipse.
`[in]`	UserData	Any user data which will be passed to the render callback.

template<class VtxT >

void sp::math::Rasterizer::rasterizeLine	(	const boost::function< void(s32 x, s32 y, const VtxT &Vertex, void *UserData)> &	RenderPixelCallback,
		const VtxT &	VertexA,
		const VtxT &	VertexB,
		void *	UserData = `0`
	)

Rasterizes a line onto a 2D screen using the "Bresenham" algorithm.

Template Parameters:

VtxT

Specifies your own vertex class. See the RasterizerVertex class and implement your own vertex class with the same interface.

Parameters:

`[in]`	RenderPixelCallback	Specifies the pixel rendering callback. Without this callback the function renders nothing. Use this to draw a pixel onto a screen or image buffer with the given x and y coordainte.
`[in]`	VertexA	First vertex for the line.
`[in]`	VertexB	Second vertex for the line.
`[in]`	UserData	Any user data which will be passed to the render callback.

template<class VtxT >

void sp::math::Rasterizer::rasterizeTriangle	(	const boost::function< void(s32 x, s32 y, const VtxT &Vertex, void *UserData)> &	RenderPixelCallback,
		const VtxT &	VertexA,
		const VtxT &	VertexB,
		const VtxT &	VertexC,
		void *	UserData = `0`
	)

Rasterizes a triangle onto a 2D screen.

Template Parameters:

VtxT

Specifies your own vertex class. See the RasterizerVertex class and implement your own vertex class with the same interface.

Parameters:

`[in]`	RenderPixelCallback	Specifies the pixel rendering callback. Without this callback the function renders nothing. Use this to draw a pixel onto a screen or image buffer with the given x and y coordainte.
`[in]`	VertexA	First vertex for the triangle.
`[in]`	VertexB	Second vertex for the triangle.
`[in]`	VertexC	Third vertex for the triangle.
`[in]`	UserData	Any user data which will be passed to the render callback.

SP_EXPORT void sp::math::Rasterizer::rasterizeTriangle	(	const RenderPixelCallback &	RenderCallback,
		dim::point2di	PointA,
		dim::point2di	PointB,
		dim::point2di	PointC,
		void *	UserData = `0`
	)

Rasterizes a triangle onto a 2D screen.

Parameters:

`[in]`	RenderCallback	Specifies the pixel rendering callback. Without this callback the function renders nothing. Use this to draw a pixel onto a screen or image buffer with the given x and y coordainte.
`[in]`	PointA	Specifies the first 2D point of the triangle.
`[in]`	PointB	Specifies the second 2D point of the triangle.
`[in]`	PointC	Specifies the third 2D point of the triangle.
`[in]`	UserData	Any user data which will be passed to the render callback.

Note:: This function does not interpolate any values between the triangle points. For this feature use the template variant.
