Member Function Documentation

int ThreadedRayCaster::checkDone

(

)

[private]

checks if any lines have finisched

Returns:

number of finished line, -1 if none

void ThreadedRayCaster::drawVolume	(	POINT	aDrawSize,
		RGBAColor *	aResultArray,
		Vector3	aDirection,
		Vector3	aPos,
		Vector3	anXDirection,
		Vector3	aYDirection
	)

renders the volume

Parameters:

	aResultArray	the result will be drawn into this
	aDirection	direction the rays are looking at
	aPos	starting position of the upper left ray
	anXDirection	horizontal position difference between two rays
	aYDirection	vertical position difference between two rays

void ThreadedRayCaster::issueLine

(

RayCalculations *

aCalculator

)

[private]

starts a new thread to render a line

Parameters:

aCalculator

the instance to render the line

bool ThreadedRayCaster::lineDone

(

unsigned int

aLineNo

)

[private]

finish the line and start the next one

Parameters:

aLineNo

the number of the line

Returns:

whether all lines are done and the casting process finished (otherwise another line has been started)

void ThreadedRayCaster::loadValues

(

)

[private]

saves all modifiable values for casting process, issued before the first thread is started

void ThreadedRayCaster::nextLine

(

)

[private]

sets the current line to the next line for progressive refinement

void ThreadedRayCaster::writeLine

(

unsigned int

aLineNo

)

[private]

writes the color data after a line is done

Parameters:

aLineNo

number of the line data shall be written for
