PGENLib.ImageTracer Struct Reference

Send rays from the Camera (observer) to corresponding pixels of an HdrImage (screen), converting "u-v" Camera coordinates to "column-raw" index of the HdrImage.

Image	must be a :class:.HdrImage object that has already been initialized
Camera	must be a descendeant of the :class:.Camera object
Pcg	random number generator
SamplePerSize	If SamplesPerSide is larger than zero, stratified sampling will be applied to each pixel in the image, using the random number generator pcg

		int	samplePerSide = 1
	)

Member Function Documentation

FireAllRays()

void PGENLib.ImageTracer.FireAllRays

(

Func< Ray, Color >

func

)

Shoot several light rays crossing each of the pixels in the image. For each pixel of the HdrImage object, fire one ray and pass it to the function func, which must accept a Ray as its only parameter and must return a Color object, representing the color to assign to that pixel in the image.

Parameters

func

FireRay()

Ray PGENLib.ImageTracer.FireRay	(	int	col,
		int	row,
		float	uPixel = 0.5f,
		float	vPixel = 0.5f
	)

Shoot one light ray through image pixel of coordinates (col, row), which are measured in the same way as in HdrImage: the bottom left corner is placed at (0, 0). The parameters (uPixel, vPixel) specify where the ray should cross the pixel: (0.5f, 0.5f) represents the pixel's center.

Parameters

col	Type int
row	Type int
uPixel	Type float in the range [0, 1], default = 0.5
vPixel	Type float in the range [0, 1], default = 0.5

Returns
