i've got complex backbone/marionette app , i'm venting things out parent elements . when need trigger things in children parent elements though, it's little unclear me how should doing this. easiest thing call method on child parent, but, wonder if "cheating" in case (and perhaps causing memory leak issues or something?) , i'm curious "right" way. here's jsfiddle of extremely simplified contrived version of code. a gist of same contrived example in require based app . <header> <h4>a subview/view trigger event loop playground</h4> <p>open console , click button</p> </header> <article id="main"> </article> <script type="text/html" id="mysubview"> <button type="button" id="button">click me</button> </script> <script type="text/html" id="myview"> <div id="myregion"...

how 1 reverse order on z axis of 3d plot (i.e. negative up, , positive down)? following code produces cone base pointing downward; there command (like ax.reverse_zlim3d(true) or something?) can used change tick order? the following code plots cone base pointing downward. reverse z-axis order plots base pointing up, ice cream cone, -1 @ top of graph instead of bottom. from matplotlib import pyplot p mpl_toolkits.mplot3d import axes3d # @unusedimport import numpy np math import pi, cos, sin z = np.arange(0, 1, 0.02) theta = np.arange(0, 2 * pi + pi / 50, pi / 50) fig = p.figure() axes1 = fig.add_subplot(111, projection='3d') zval in z: x = zval * np.array([cos(q) q in theta]) y = zval * np.array([sin(q) q in theta]) axes1.plot(x, y, -zval, 'b-') axes1.set_xlabel("x label") axes1.set_ylabel("y label") axes1.set_zlabel("z label") p.show() use invert_zaxis method of axes3d : from matplotlib import pyplo...

brad larson provides great code here , here 'rendering scene texture-backed framebuffer', it's not clear whether same framebuffer use rest of drawing. if attach renderbuffer framebuffer, can framebuffer render texture same call? sounds might bit confused fbo usage. if need it, should started: apple developer - drawing offscreen . this too. renderbuffer can bind fbo (framebuffer object). fbo create when don't want rendering displayed immediately, want read rendering result or perform additional rendering it. way fbos work in opengl es 2.0, have 1 color attachment point available (gl_color_attachment0 - fragment shader output variable gl_fragcolor connected attachment point), , can have 1 texture or renderbuffer attached it. answer last question, cannot have fbo simultaneously write color renderbuffer , texture. as first part of question, depends whether using fbo or default framebuffer. chances behavior you're looking this: bind fbo render t...
