Interactive Computer Graphics with WebGL, by Edward Angel (University of New Mexico, USA)
Introduction to Programming with MATLAB, by Akos Ledeczi, Michael Fitzpatrick, Robert Tairas (Vanderbilt University, USA)
This is just one of the many videos available at the ACM Siggraph YouTube Channel. Definitely worth a visit.
Selecting, a particular item in a 3D scene may prove useful for some applications. The selection can be performed by clicking on an object, requiring a way to determine over which object was the mouse placed.
This short tutorial shows how to select objects with the mouse using color coding. Source code and a VS2010 project are provided.
The code sample for importing and displaying 3D models with Assimp, using modern OpenGL, has been updated to cover Assimp 3.0.
A Visual Studio 2010 project has also been added to help readers to get started.
A Computer Grahpics course is available at EdX, by Ravi Ramamoorthi, a Professor at UC Berkeley. By the end of the course students should understand the concepts of 3D graphics, and develop programs that create images of a 3D scene with lighting, using both real-time OpenGL and GLSL programming, as well as offline raytracing.
Eric Haines (co-author of Real-Time Rendering) is lecturing an online course at Udacity – Interactive 3D Graphics. The course covers the basic principles of 3D computer graphics, including meshes, geometric transformation, camera definition, lighting and materials, and also animation.
The GLSL Core Tutorial has a new section for image texturing. Images are commonly used as wallpaper applied to 3D shapes to create a variety of effects. In this section we focus on the OpenGL and GLSL typical scenario of texture usage, and explore a few new GLSL functions, such as
Based only on texture coordinates some interesting shaders can be built. In this new section of the GLSL Core Tutorial, a few common shaders, namely the stripes and grid shaders, will be explored. Basic antialising and GLSL functions mix and smoothstep will also be discussed. Source code and a VS2010 solution are also provided.
