After Effects expressions library From Mographwiki.net For general information and resources about expressions, go to the After Effects expressions page. One-sided layers Apply this expression to the opacity attribute and it'll disappear whenever it's flipped away from the camera. a = toWorldVec([0,0,1]); b = thisComp.activeCamera.position - toWorld(anchorPoint); c = dot(a,b)/length(b); if (c > 0) 0 else value Object bouncing on a floor This will make your layer/object bounce along an imaginary 'floor'. Vy0 = 500; //initial y velocity (pixels/second) Vx0 = 100; // initial x velocity (pixels/second) g = 2500; // gravity (pixels/second/second) floor = 400; e = .85; //elasticity b = floor - position[1]; h = b + Vy0*Vy0/(2*g); T = Vy0/g + Math.sqrt(2*h/g); if (time < T){ y = Vy0*time - g*time*time/2 + b; }else{ Vy = -(Vy0 - g*T); while (true){ Vy *= e; t = T; T += 2*Vy/g; if (time < T){ t = time - t; y = Vy*t - g*t*t/2; break; }else if (T - t < thisComp.frameDuration){ y = 0; break; } } } [position[0] + Vx0*time, floor - y]
How do I add an email contact form to my website? : Visitors to your website want to contact you. You need a way to help them do that. At first it seems simple— just design an HTML form. But then you're stumped. What happens next? There are easy fixes and sneaky workarounds for this problem. <a href="mailto:myaccount@mydomain.com">Send Me Email</a> But this approach results in massive quantities of incoming spam (junk email), as automated software harvests your email address and begins transmitting garbage you have no desire to read. Also, this approach doesn't allow you to control the format of the user's message in any way.

Unfortunately, there are several major problems with the mailto: form action strategy: 1. 2. 3. "Great! <? 1. 2.
Expressions Expressions in After Effects I've added some pages designed to teach a few topics in geometry relevant to expressions in After Effects. This section focuses more on math than on syntax, and assumes that you're familiar with the basics of creating and using expressions. These pages are still fairly rough—I'll be revising them and adding new pages over the next week or two. The geometry material starts here. These pages are focused on Expressions, a feature new to After Effects 5.0. For now, the site consists mainly of a set of pages designed to teach you the basics of using expressions in After Effects. In addition, I've compiled a set of useful reference tables showing the attributes, methods and sub-objects belonging to each of After Effects' objects.
