Now using this function we get the z value which keep in mind, is not normalized. Sometimes though, you want to use another formula, so in order to do that, we must first get the z-value by linearizing the depth function, which can be done using this function. Don't worry, we don't have to implement it since OpenGL does it automatically. Since we almost always focus on things that are close to us, we want to make the precision be very high near us, and low away from us. If the depth was linear, then we would have the same amount of precision for depth at a close distance as we would at a far away distance. This is due to the fact that depth in OpenGL is not linear. The only way to see a bit of darkness is to get very close to an object. The problem is, that as soon as we press run, you'll notice the screen is mostly pure white. We can easily do this by going to the fragment shader and outputting gl_FragCoord.z as the FragColor. In most circumstances you should use GL_LESS, but I suppose you could also choose one of the others if you want your game or application to be mind bending. By default OpenGL chooses GL_LESS which means that if the depth value of an object is less than that of the current depth value, then the first value replaces the second. We can do this by using the glDepthFunc and inserting one of the following inputs.

Using this depth information, we can asses which object should be in front of which other object. A depth value of 0 meaning that it's right on the near plane, and of 1 meaning it's on the far plane. Now what this buffer basically does, is that it stores 'depth' values that represent how far away from the near plane of the projection matrix a certain fragment is. Since the buffer is turned off by default, we want to make sure we have it enabled, and that we clear it each frame just like the Color Buffer.

You might remember that we've already made use of the Depth Buffer in the 'Going 3D' tutorial in order to fix a weird issue we had. In this tutorial we'll take a look at Depth Buffers in OpenGL and also see how we can make use of them for a little graphical effect. And that should be all you need to know about this course, enjoy! If you don't know what OpenGL is or are not familiar with it, then you should first watch the beginners course for OpenGL which you can find on this channel. Hi everyone! In this course I'll teach you about different advanced topics in OpenGL that will help you achieve more complex effects, better looking renders, and more optimized scenes. This advanced OpenGL course from Victor Gordan will take your skills to the next level. OpenGl can be used to create complex graphics effects. Watch the course below or on the YouTube channel (1-hour watch). Here are the topics covered in this course: Now, he will help you take your skills to the next level. Before this course he created one of the most popular OpenGL course on YouTube. We just released an advanced OpenGL course on the YouTube channel. Just remove it and you should be fine.OpenGL can be used to create complex 2D and 3D graphics effects. Here's a project file: Dropbox - TrimPath with faded tail.aepвЂ‹ (note: your browser will probably add a. Your gradient layer should follow the exact path of the stroke.ДЄll you have to do now is set the top shape layer with the gradient fill as an inverted alpha track matte for the path and adjust the timing of the move to match the timing of the animated path.ДЄs long as your path does not cross itself or have corners that are too sharp this should work just fine.

Now press Alt/Option + p to set a keyframe for position and paste. Then edit the gradient so the start point is at 0, 0 and is any color but fully opaque and the end color is any color but 100% transparent and, if you want the fade to be 200 pixels set the end point to 0, 200. The second step is to create another shape layer with a radial gradient fill by double clicking the rectangle or the ellipse tool. Add trim paths to shape 1 and then animate the start and end points of the path. The easiest way I can think of to do this would be to start by drawing a shape layer with only a stroked path using the pen tool, press the U key twice to reveal the modified properties of the path, set a keyframe for the Shape 1 > Path 1 and copy it.
