<?xml version="1.0" encoding="utf-8"?> <!-- This light material matches the emission spectrum of sodium vapor. The spectrum is simulated, based on peaks wavelength and areas found in litterature (source : NIST). There is no continuous background, only the emission peaks. Could be slightly blended with a blackbody (Ex : 10000K) to get properties similar to vapor discharge lamps. --> <scenedata> <material> <name>sodium-emission</name> <phong> <diffuse_albedo> <constant> <rgb> <rgb> 0.8 0.8 0.8 </rgb> <gamma>2.2</gamma> </rgb> </constant> </diffuse_albedo> <exponent> <constant> 1000 </constant> </exponent> <base_emission> <constant> <regular_tabulated> <start_wavelength>4e-007</start_wavelength> <end_wavelength>7e-007</end_wavelength> <num_values>301</num_values> <values> 2.30016E-24 1.20934E-19 2.33913E-15 1.66457E-11 4.35854E-08 4.20053E-05 0.014911859 1.95382068 94.95614678 1732.660164 12202.0852 34980.04089 43850.46068 25005.27116 6262.762962 641.3991296 25.42028747 0.378770833 0.017985629 2.01330223 95.45589694 1722.967605 12192.44139 35216.88944 43032.97488 22605.67742 6542.035616 8149.958983 25829.37418 53766.13246 68731.34354 72162.17716 63696.59874 54086.82795 50347.71229 34356.9474 27130.61416 41488.70558 56704.65695 66879.65563 53622.15346 26543.15848 9162.279078 12220.23748 44463.7157 81898.17886 76425.05374 65414.05208 84363.67073 98788.79802 87317.70756 62743.24305 53955.82401 47458.73025 33908.12666 25200.05097 13948.97287 5013.550056 8297.368212 14433.45357 9590.678801 2346.157559 211.8903499 53.75762449 1113.555071 10095.75159 34777.10607 45329.60522 22249.57206 4174.857956 1622.161467 8524.773185 23387.92085 33057.42078 29917.236 19898.59461 15738.09255 16875.78188 13949.48768 10515.9767 4940.347122 957.7134908 69.46764568 1.857992964 0.018287227 6.62179E-05 8.82087E-08 4.32268E-11 7.80819E-15 1.78728E-13 7.753E-10 1.25015E-06 0.000752721 0.170228478 14.5607842 474.5324805 5929.161842 28504.87566 52716.75776 37356.91828 10078.21136 1027.549159 39.32252341 0.561586049 0.002980045 5.85703E-06 4.25416E-09 1.22225E-10 2.0021E-07 0.000123513 0.028610417 2.50835749 83.97933833 1082.48809 5400.164029 10432.62501 7827.812873 3085.408759 4954.219267 10235.57123 11412.57967 8847.016925 3922.475987 731.4723496 51.60285114 1.346321654 0.01293465 4.5724E-05 5.9464E-08 2.84494E-11 5.00799E-15 1.07815E-14 5.54818E-11 1.05037E-07 7.31588E-05 0.01874959 1.769362144 61.65316354 802.1935482 4066.795921 9156.584352 11365.78495 7961.788565 2550.510611 322.0939331 15.2386885 0.266432131 0.001715594 4.06505E-06 3.54366E-09 1.13645E-12 1.34078E-16 5.81927E-21 9.2915E-26 5.45769E-31 1.61483E-34 5.60221E-29 7.20721E-24 3.4149E-19 5.9643E-15 3.84538E-11 9.17459E-08 8.13353E-05 0.026969479 3.378273552 162.0652212 3025.468682 22289.35188 65216.18516 75438.29814 34049.79346 5901.58423 387.2258599 9.516829395 0.086989872 0.000294414 3.67955E-07 1.69546E-10 2.87761E-14 1.47171E-15 1.95567E-11 9.57887E-08 0.000172821 0.114972287 28.2558242 2573.689935 87370.87773 1115638.389 5433322.929 10279789.25 7702618.079 2314830.254 278826.8692 13279.43287 245.2516666 1.724974264 0.004558821 4.48751E-06 1.63654E-09 2.2043E-13 1.09465E-17 2.00223E-22 1.34819E-27 3.36311E-30 5.06268E-25 2.80761E-20 5.73249E-16 4.31234E-12 1.19686E-08 1.22873E-05 0.004688355 0.670552402 36.46445547 770.1181873 6485.428804 22353.72049 32559.60289 22109.33733 9639.990029 6276.748395 6598.74363 3873.95049 2897.440956 5816.003262 6497.410638 6687.147305 9942.332162 10881.36371 7288.382571 2341.050222 300.4943436 14.49954927 1.724457683 57.90475969 870.630476 5051.744172 11454.51803 10224.34582 3588.75709 490.8884793 25.82544468 0.515780035 0.00386925 1.08201E-05 2.01867E-08 9.08766E-06 0.00339174 0.466749186 23.79018282 455.4468753 3419.680017 11359.0714 21138.34671 28748.76771 34333.88385 29770.02299 13169.09444 2579.263444 213.6685192 7.198318063 0.09496034 0.000477159 8.98193E-07 6.27712E-10 1.62121E-13 1.54384E-17 5.41453E-22 6.98981E-27 3.32045E-32 5.80355E-38 3.73187E-44 8.82836E-51 7.68328E-58 2.45993E-65 2.89739E-73 1.25544E-81 2.00121E-90 1.1735E-99 2.5316E-109 2.0092E-119 5.8659E-130 6.3003E-141 2.4894E-152 3.6185E-164 1.9349E-176 3.8064E-189 2.7546E-202 7.3336E-216 7.1826E-230 2.5879E-244 3.4302E-259 1.6726E-274 3.0005E-290 0 0 0 0 0 0 0 7.0086E-300 </values> </regular_tabulated> </constant> </base_emission> <layer>0</layer> </phong> </material> </scenedata>
