Easing functions specify the speed of animation to make the movement more natural. Real objects don’t just move at a constant speed, and do not start and stop in an instant. This page helps you choose the right easing function.

Does anyone have an algorithm for creating a sphere proceduraly with la amount of latitude lines, lo amount of longitude lines, and a radius of r? I need it to work with Unity, so the vertex positi...

While implementing my Sky Dome for atmospheric Scattering a number of issue quickly became noticeable. A sphere generated using the OpenGL f...

Paul Bourke - Geometry, Surfaces, Curves, Polyhedra

The photo-realistic reproduction of natural terrains is a classical challenge in computer graphics and the interactive display of non-trivial landscapes is only possible with recent graphics hardware. The reasons for this are the vast amount of data due to geometric detail of the terrain, vegetation and further objects, but also the inherent complexity of natural phenomena that are necessary to achieve convincing results. Realistic terrain rendering also has to consider the complex lighting conditions due to atmospheric scattering and further aspects such as the rendering of waterbodies and cloudscapes. One focus of this dissertation are procedural models for terrain elevation and texturing. They can either be used to create completely artificial, realistic landscapes, mimic real terrains by guiding the models with real-world data or augment acquired data with additional procedural detail. By this, we can reproduce natural scenes with the advantage of a compact procedural description. Another emphasis is placed on the interactive rendering of such terrains including specifically tailored level-of-detail methods and lighting computations for terrains and rendering techniques for complex plant models. We introduce a set of novel techniques and algorithms that address the aforementioned problems and achieve results in real-time with photo-realistic image quality using programmable graphics hardware. In particular, we propose new algorithms for a data-guided height field creation, realistic terrain surface texture generation, a novel level-of-detail method for terrain rendering and hardware friendly, efficient point-based rendering and splatting techniques. We also provide a comprehensive presentation of underlying theories and related work to put our work in perspective of the research area.

I managed to get an OpenGL program working in XCode (IDE that comes with a Mac) with C++ as a base.  Given that my long-term memory tends to...

First I have to start with a quick explanation for people who don’t know what OpenGL is. OpenGL is NOT a language. In fact, OpenGL is merely a specification which is implemented in various la…

As far as I'm aware, the Macbook Air 2012 supports OpenGL 3.2. When using SDL 2.0 to create the OpenGL context, however, the context is only opengl version 2.1. Is it possible for SDL 2.0 to creat...
