Member Function Documentation

cleanUp()

void DoFShader::cleanUp

(

)

unbind everything

draw()

void DoFShader::draw	(	FBO *	fbo0,
		FBO *	fbo1,
		float	C,
		bool	f2b
	)

renders a slice of the volume

Parameters

fbo0	previous framebuffer
fbo1	current framebuffer
C	circle of confusion
f2b	bool indicating if rendered front to back or back to front

loadDepth()

void DoFShader::loadDepth	(	float	depthZCoord,
		float	distance
	)

loads up the depth values to the shader

Parameters

depthZCoord	distance from camera to slice
distance	distance between slices

prepare()

void DoFShader::prepare	(	GLCamera &	camera,
		const GLuint &	quadVAO,
		const GLuint &	volTEX
	)

bind matrices, VAO and texture

Parameters

camera	contains model, view, projection matrices
quadVAO	VAO for a simple quad
volTEX	ID for the current volume slice

refresh()

void DoFShader::refresh

(

)

recompile the shader, for debugging
