Thanks for the replies. None of these things seem to be the case as far as I can tell. Back to banging my head against the wall.

In Topic: Question about spherical spreading of light.

15 December 2010 - 05:56 AM

This has been enlightening so far. I'm guessing that with exponential attenuation (e^-a*dis) for say fog this would be applied to the distance from light to object(d1) and the distance from object to camera (d2). So the final attenuation would be (e^-a*(d1+d2)) due to the absorption/scattering of light?

Can someone working in the game industry tell me if vacation time usually goes up with job experience. What kind of time off would a senior programmer get?

In Topic: Using perlin noise to generate wind turbulence for particle effects.

23 August 2007 - 05:33 AM

float Perlin::perlin_noise_3D(float vec[3])
float result = 0.0f;


float divider = 0;
float scale = 1;
for (int i=0;i<_octaves;i++)
result += noise3(vec)*scale;

vec[0] *= 2.0f;
vec[1] *= 2.0f;
vec[2] *= 2.0f;

divider += scale;
scale *= 0.5f;

return _amplitude*pow(result/divider,3.0f);

Are these the right changes? The effect seems a bit better. Are there any articles or samples that you could link me to that might increase my understanding of all this?

Thanks for the responces. Looks like I'll have a great starting point.
