animation

问题 How to animate the zoom of camera in three.js with orthigraphic camera. Without animation it is very simple. I only have to set camera.zoom = 1 . But I want to animate it with tween.js. There is my codePen: http://codepen.io/anon/pen/yVOOLj?editors=1111 var scene = new THREE.Scene(); var camera = new THREE.OrthographicCamera(640 / -2, 640 / 2, 380 / 2, 380 / -2, -5000, 5000); camera.position.set(100,100,100); camera.zoom = 0.1; var renderer = new THREE.WebGLRenderer(); renderer.setSize( 640,

问题 The Plotly documentation on heatmap animation is pretty difficult to understand. Could someone explain how to animate a heatmap? Here is my specific example. import numpy as np from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot import plotly.graph_objs as go init_notebook_mode(connected=True) x = np.linspace(0, 1, 200) y = np.linspace(0, 1, 200) xx, yy = np.meshgrid(x, y) def plane_wave(phase): return np.sin(8*np.pi * (xx - phase)) zz = plane_wave(0) trace = go

The view animation slides in from the right perfectly, but when I click on the Close button, the view disappears without the desired animation of sliding back to the right before disappearing. I have tried using .opacity(self.isShowing ? 1 : 0), but then the View fades in and out, I need it to slide in and out. Other variations have not produced the desired results. What am I doing wrong? Any guidance, even a duplicate solution (that I could

问题 I can't seem to figure out how to programmatically set a new image, via the outlet, and make it start animating. Sequence zeroEntering0.png zeroEntering1.png zeroEntering2.png zeroEntering3.png zeroEntering4.png I imported the sequence of images into the Image.xcassets inside the WatchKit App I can set the image in the interface builder to "zeroEntering" and set animating to "Yes" and it works correctly.

问题 I'm using animation in my app and get confused, because animation is lagging on device, on simulator everything seems OK. First I tried to use [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.3]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; And before commit animation there were something like ~30 lines of code with "if" blocks so I thought this might cause the problem, but then I start to use [UIView animateWithDuration:0.3 delay:0.0 options:
