three.js - mesh looks incorrect (threejs r68) -


i'm using threejs (r68) on model online view project converts uploaded models threejs files. found models incorrect below.

mesh incorrect

some models can viewed @ http://www.threedbook.com/detail/23981

especially when move models(rotate or pan), mesh color , shade changing time. strange thing model normal if it's zoomed in enough size. point me causes rendering problem? or issue when convert models threejs file?

thanks lot!

the modelling of object incorrect. have overlapping polygons on same area , close each other. when rendering, cause appearance change (specially if zoomed out since dont have enough rendering resolution); ie. many polygons squashed on top of each other , renderer doesn't know 1 render first. when zoom in, ok because have resolution.

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
