Paramètres

csOrigin	Camera-space ray origin, which must be within the view volume and must have z < -0.01 and project within the valid screen rectangle.
csDirection	Unit length camera-space ray direction.
projectToPixelMatrix	A projection matrix that maps to pixel coordinates (not [-1, +1] normalized device coordinates).
csZBuffer	The depth or camera-space Z buffer, depending on the value of csZBufferIsHyperbolic.
csZBufferSize	Dimensions of csZBuffer.
csZThickness	Camera space thickness to ascribe to each pixel in the depth buffer.
csZBufferIsHyperbolic	True if csZBuffer is an OpenGL depth buffer, false (faster) if csZBuffer contains (negative) "linear" camera space z values. Const so that the compiler can evaluate the branch based on it at compile time.
clipInfo	See G3D::Camera documentation.
nearPlaneZ	Negative number.
stride	Step in horizontal or vertical pixels between samples. This is a float because integer math is slow on GPUs, but should be set to an integer >= 1.
jitterFraction	Number between 0 and 1 for how far to bump the ray in stride units to conceal banding artifacts.
maxSteps	Maximum number of iterations. Higher gives better images but may be slow.
maxRayTraceDistance	Maximum camera-space distance to trace before returning a miss.
hitPixel	Pixel coordinates of the first intersection with the scene.
csHitPoint	Camera space location of the ray hit.
