Cool Looking FogThis tutorial code was generously donated to the site by Chris Aliotta. It based on the code from lesson 7, that why you're seeing the famous crate again:) It's a pretty short tutorial aimed at teaching you the art of fog. You'll learn how to use 3 different fog filters, how to change the color of the fog, and how to set how far into the screen the fog starts and how far into the screen it ends.
Definitely a nice effect to know!2D Texture FontThe original version of this tutorial code was written by Giuseppe D'Agata. In this tutorial you will learn how to write any character or phrase you want to the screen using texture mapped quads. You will learn how to read one of 256 different characters from a 256x256 texture map, and finally I will show you how to place each character on the screen using pixels rather than units. Even if you're not interested in drawing 2D texture mapped characters to the screen, there is lots to learn from this tutorial. Definitely worth reading!QuadricsThis tutorial code was written by GB Schmick the wonderful site op over at TipTup. It will introduce you to the wonderful world of quadrics.
Jun 14, 2013 OpenGL code for making a simple Fountain This source code is for making a simple fountain. In this program, we made three balls and they disperse from one point after every few time. OpenGL program:- #include Fountain ★ Collision Detection between two Objects ★ All in one OpenGL programs. Posted by Md Mohsin at. The given program will Encrypt and Decrypt a message using RSA Algorithm. Android SQLite Database Tutorial and Project.
With quadrics you can easily create complex objects such as spheres, discs, cylinders and cones. These object can be created with just one line of code. With some fancy math and planning it should be possible to morph these objects from one object into another. Please let GB Schmick know what you think of the tutorial, it's always nice when visitors contribute to the site, it benefits us all.
Everyone that has contributed a tutorial or project deserves credit, please let them know their work is appreciated!Particle Engine Using Triangle StripsHave you ever wanted to create an explosion, water fountain, flaming star, or some other cool effect in your OpenGL program, but writing a particle engine was either too hard, or just too complex? If so, this tutorial is for you. You'll learn how to program a simple but nice looking particle engine. I've thrown in a few extras like a rainbow mode, and lots of keyboard interaction. You'll also learn how to create OpenGL triangle strips. I hope you find the code both useful and entertaining.MaskingUp until now we've been blending our images onto the screen. Although this is effective, and it adds our image to the scene, a transparent object is not always pretty.
Lets say you're making a game and you want solid text, or an odd shaped console to pop up. With the blending we have been using up until now, the scene will shine through our objects. By combining some fancy blending with an image mask, your text can be solid. You can also place solid oddly shaped images onto the screen. A tree with solid branches and non transparent leaves or a window, with transparent glass and a solid frame. Lots of possiblities!
