Method Details

render

public void render()

getRayThroughPoint

public Ray getRayThroughPoint(Camera camera,
 double normalizedX,
 double normalizedY)

Return the ray, in world space, that starts at the camera and passes through this viewport at (x,y) in the current projection. x,y should be normalized screen coordinates adjusted for the vertical flip.

Remember that in OpenGL the camera -Z=forward, +X=right, +Y=up

Parameters:

normalizedX - the cursor position in screen coordinates [-1,1]

normalizedY - the cursor position in screen coordinates [-1,1]

Returns:

the ray coming through the viewport in the current projection.

getRayThroughPointUntransformed

public Ray getRayThroughPointUntransformed(Camera camera,
 double normalizedX,
 double normalizedY)

Return the ray, in camera space, that starts at the origin and passes through this viewport at (x,y) in the current projection. x,y should be normalized screen coordinates adjusted for the vertical flip.

Remember that in OpenGL the camera -Z=forward, +X=right, +Y=up

Parameters:

normalizedX - the cursor position in screen coordinates [-1,1]

normalizedY - the cursor position in screen coordinates [-1,1]

Returns:

the ray coming through the viewport in the current projection.

getStartTime

public long getStartTime()

setSize

public void setSize(int width,
 int height)

Set the size of the canvas. Destroys the previous image and creates a new one.

Parameters:

width - the width

height - the height

getImage

public BufferedImage getImage()

setActiveCamera

public void setActiveCamera(Camera camera)

getMaxDepth

public int getMaxDepth()

setMaxDepth

public void setMaxDepth(int maxDepth)

getSamplesPerPixel

public int getSamplesPerPixel()

setSamplesPerPixel

public void setSamplesPerPixel(int samplesPerPixel)

getAspectRatio

public double getAspectRatio()

addProgressListener

public void addProgressListener(PathTracerPanel pathTracerPanel)
