Since ART is not a small system and is intended to +be inter-operable with other libraries, and since C does not have namespaces, +the structures and functions in ART all have to have somewhat wordy +canonical names that begin with Ar.../ar..., like those seen in this example. + +Usage information: +================== + + +Model initialisation +-------------------- + +A separate ArHosekSkyModelState has to be maintained for each spectral +band you want to use the model for. So in a renderer with 'num_channels' +bands, you would need something like + + ArHosekSkyModelState * skymodel_state[num_channels]; + +You then have to allocate and initialise these states. In the following code +snippet, we assume that 'albedo' is defined as + + double albedo[num_channels]; + +with a ground albedo value between [0,1] for each channel. The solar elevation +is given in radians. + + for ( unsigned int i = 0; i < num_channels; i++ ) + skymodel_state[i] = + arhosekskymodelstate_alloc_init( + turbidity, + albedo[i], + solarElevation + ); + +Note that starting with version 1.3, there is also a second initialisation +function which generates skydome states for different solar emission spectra +and solar radii: 'arhosekskymodelstate_alienworld_alloc_init()'. + +See the notes about the "Alien World" functionality provided further down for a +discussion of the usefulness and limits of that second initalisation function. +Sky model states that have been initialised with either function behave in a +completely identical fashion during use and cleanup. + +Using the model to generate skydome samples +------------------------------------------- + +Generating a skydome radiance spectrum "skydome_result" for a given location +on the skydome determined via the angles theta and gamma works as follows: + + double skydome_result[num_channels]; + + for ( unsigned int i = 0; i < num_channels; i++ ) + skydome_result[i] = + arhosekskymodel_radiance( + skymodel_state[i], + theta, + gamma, + channel_center[i] + ); + +The variable "channel_center" is assumed to hold the channel center wavelengths +for each of the num_channels samples of the spectrum we are building. + + +Cleanup after use +----------------- + +After rendering is complete, the content of the sky model states should be +disposed of via + + for ( unsigned int i = 0; i < num_channels; i++ ) + arhosekskymodelstate_free( skymodel_state[i] ); + + +CIE XYZ Version of the Model +---------------------------- + +Usage of the CIE XYZ version of the model is exactly the same, except that +num_channels is of course always 3, and that ArHosekTristimSkyModelState and +arhosek_tristim_skymodel_radiance() have to be used instead of their spectral +counterparts. + +RGB Version of the Model +------------------------ + +The RGB version uses sRGB primaries with a linear gamma ramp. The same set of +functions as with the XYZ data is used, except the model is initialized +by calling arhosek_rgb_skymodelstate_alloc_init. + +Solar Radiance Function +----------------------- + +For each position on the solar disc, this function returns the entire radiance +one sees - direct emission, as well as in-scattered light in the area of the +solar disc. The latter is important for low solar elevations - nice images of +the setting sun would not be possible without this. This is also the reason why +this function, just like the regular sky dome model evaluation function, needs +access to the sky dome data structures, as these provide information on +in-scattered radiance. + +CAVEAT #1: in this release, this function is only provided in spectral form! + RGB/XYZ versions to follow at a later date. + +CAVEAT #2: (fixed from release 1.3 onwards) + +CAVEAT #3: limb darkening renders the brightness of the solar disc + inhomogeneous even for high solar elevations - only taking a single + sample at the centre of the sun will yield an incorrect power + estimate for the solar disc! Always take multiple random samples + across the entire solar disc to estimate its power! + +CAVEAT #4: in this version, the limb darkening calculations still use a fairly + computationally expensive 5th order polynomial that was directly + taken from astronomical literature. For the purposes of Computer + Graphics, this is needlessly accurate, though, and will be replaced + by a cheaper approximation in a future release. + +"Alien World" functionality +--------------------------- + +The Hosek sky model can be used to roughly (!) predict the appearance of +outdoor scenes on earth-like planets, i.e. planets of a similar size and +atmospheric make-up. Since the spectral version of our model predicts sky dome +luminance patterns and solar radiance independently for each waveband, and +since the intensity of each waveband is solely dependent on the input radiance +from the star that the world in question is orbiting, it is trivial to re-scale +the wavebands to match a different star radiance. + +At least in theory, the spectral version of the model has always been capable +of this sort of thing, and the actual sky dome and solar radiance models were +actually not altered at all in this release. All we did was to add some support +functionality for doing this more easily with the existing data and functions, +and to add some explanations. + +Just use 'arhosekskymodelstate_alienworld_alloc_init()' to initialise the sky +model states (you will have to provide values for star temperature and solar +intensity compared to the terrestrial sun), and do everything else as you +did before. + +CAVEAT #1: we assume the emission of the star that illuminates the alien world + to be a perfect blackbody emission spectrum. This is never entirely + realistic - real star emission spectra are considerably more complex + than this, mainly due to absorption effects in the outer layers of + stars. However, blackbody spectra are a reasonable first assumption + in a usage scenario like this, where 100% accuracy is simply not + necessary: for rendering purposes, there are likely no visible + differences between a highly accurate solution based on a more + involved simulation, and this approximation. + +CAVEAT #2: we always use limb darkening data from our own sun to provide this + "appearance feature", even for suns of strongly different + temperature. Which is presumably not very realistic, but (as with + the unaltered blackbody spectrum from caveat #1) probably not a bad + first guess, either. If you need more accuracy than we provide here, + please make inquiries with a friendly astro-physicst of your choice. + +CAVEAT #3: you have to provide a value for the solar intensity of the star + which illuminates the alien world. For this, please bear in mind + that there is very likely a comparatively tight range of absolute + solar irradiance values for which an earth-like planet with an + atmosphere like the one we assume in our model can exist in the + first place! + + Too much irradiance, and the atmosphere probably boils off into + space, too little, it freezes. Which means that stars of + considerably different emission colour than our sun will have to be + fairly different in size from it, to still provide a reasonable and + inhabitable amount of irradiance. Red stars will need to be much + larger than our sun, while white or blue stars will have to be + comparatively tiny. The initialisation function handles this and + computes a plausible solar radius for a given emission spectrum. In + terms of absolute radiometric values, you should probably not stray + all too far from a solar intensity value of 1.0. + +CAVEAT #4: although we now support different solar radii for the actual solar + disc, the sky dome luminance patterns are *not* parameterised by + this value - i.e. the patterns stay exactly the same for different + solar radii! Which is of course not correct. But in our experience, + solar discs up to several degrees in diameter (! - our own sun is + half a degree across) do not cause the luminance patterns on the sky + to change perceptibly. The reason we know this is that we initially + used unrealistically large suns in our brute force path tracer, in + order to improve convergence speeds (which in the beginning were + abysmal). Later, we managed to do the reference renderings much + faster even with realistically small suns, and found that there was + no real difference in skydome appearance anyway. + Conclusion: changing the solar radius should not be over-done, so + close orbits around red supergiants are a no-no. But for the + purposes of getting a fairly credible first impression of what an + alien world with a reasonably sized sun would look like, what we are + doing here is probably still o.k. + +HINT #1: if you want to model the sky of an earth-like planet that orbits + a binary star, just super-impose two of these models with solar + intensity of ~0.5 each, and closely spaced solar positions. Light is + additive, after all. Tattooine, here we come... :-) + + P.S. according to Star Wars canon, Tattooine orbits a binary + that is made up of a G and K class star, respectively. + So ~5500K and ~4200K should be good first guesses for their + temperature.
