Member Function Documentation

void LightRayRenderer::addLightRay

(

const LightRay &

lightRay

)

Adds a new LightRay that will be rendered. Dynamic LightRays are added without checking whether they exist or not. Static LightRays will be only added if the LightRay is not already drawn by LightRayRenderer.

Parameters

lightRay

The LightRay that is added

void LightRayRenderer::calculateVertexDataFor ( const LightRayData &  rayData, QVector< float > &  vertices, QVector< unsigned int > &  indices  )

protected

Calculates vertex data out of start and end position of a ray.

Parameters

rayData	The ray that should be drawn and requires vertex data
vertices	A vector the vertex data will be appended
indices	A vector the index data will be appended

void LightRayRenderer::paint ( QOpenGLFunctions &  gl, const QMatrix4x4 &  viewProjection, QOpenGLShaderProgram &  shaderProgram  )

virtual

Paints all LightRays.

Parameters

gl	QOPenGLFunctions which are used for gl-calls
viewProjection	The viewprojection matrix for drawing the rays.
shaderProgram	The shader program that will be used to draw rays.

void LightRayRenderer::resetDynamicRays

(

)

Removes all dynamic rays. It is suggested to do so every frame.
