ive been looking a the atmosphere chapter in GPU gems 2... ive done a few trys to implement it but can get it to work... so i tried just copying the code directly from the supplied disc.. but still it doesnt work... all i get is a black dome where i get some whithecolored vertexes as i move with the camera... what am i doin wrong?

 SunAngle = 45.0f;
		void CompToPolar(int angle)
			x = -(float)cos(angle*PIOVER180);
			y = -(float)sin(angle*PIOVER180);

	float m_nSamples = 3;		// Number of sample rays to use in integral equation
	float m_Kr = 0.0025f;		// Rayleigh scattering constant
	float m_Kr4PI = m_Kr*4.0f*PI;
	float m_Km = 0.0010f;		// Mie scattering constant
	float m_Km4PI = m_Km*4.0f*PI;
	float m_ESun = 20.0f;		// Sun brightness constant
	float m_g = -0.990f;		// The Mie phase asymmetry factor
	float m_fExposure = 2.0f;

	float m_fInnerRadius = 1000.0f;
	float m_fOuterRadius = 1250.0f;

	float m_fWavelength[3];
	 m_fWavelength[0] = 0.650f;		// 650 nm for red
	 m_fWavelength[1] = 0.570f;		// 570 nm for green
	 m_fWavelength[2] = 0.475f;		// 475 nm for blue
	float m_fWavelength4[3];
	 m_fWavelength4[0] = powf(m_fWavelength[0], 4.0f);
	 m_fWavelength4[1] = powf(m_fWavelength[1], 4.0f);

// SHADERS... COPIED RIGHT FROM THE CD.. "SkyFromAtmosphere"

i dont know if its allowed to post the code from the book here on the forums... if anybody knows if its okey hten ill post that also...
