in order avoid xy problem, let me explain i'm coming from. plot large number of waveforms stacked on top of each other using same time axis, using three.js. waveforms three.line's , implementing zoom/pan/scaling of these waveforms modifying view bounds of orthographic camera. my initial attempt @ accomplishing lead me create multiple canvas elements fixed height, stacked on top of each other, , attach three.webglrenderer each canvas. worked perfectly, until tried scaling past 15 or waveforms, three.js gave me warning "too many active webgl contexts", , started deleting old contexts. i feel decent practice, considering it's same technique applied here: http://threejs.org/examples/#webgl_multiple_canvases_grid in example, 4 webglrenderers created, 1 each canvas. so, possible override warning somehow, , create unbounded number of canvas elements, each own renderer? aside: i have considered using 1 scene , positioning waveforms accordingly within it,...
