One of the features that was not selected to be part of the core functionality was matrix handling. Previously we had OpenGL and GLU functions that provided the means for easily setting the camera, defining projections, and performing geometric transformations on graphical objects. The Very Simple Matrix Library (VSML) aims at providing users with a … Read more
Dynamics and Particle Effects is a two part article on creating particle systems on Maya. Smoke and rain are two of the effects that are taught in this tutorial by Audri Phillips from Intel. From their very inception, 3D programs have been used to imitate natural phenomena, creating realistic, stylized, or artistic effects. A greater … Read more
Learning Modern 3D Graphics Programming is almost an online book on core OpenGL. It covers a lot of ground, from drawing a triangle to HDR. The index promises a continuation onto texturing, render targets, and advanced lighting.
PhysX, NVIDIAs physics engine, has suffered a major revision and apparently a major rewrite. Details can be found at physxinfo.com, Geeks3D, and of course NVIDIA PhysX site.
Paul Firth has three physics tutorials (two of them for dummies 🙂 ) that look very interesting: Physics engines for dummies, Collision detection for dummies, and Speculative Contacts – a continuous collision engine approach.
The code for several demos in the GLUT tutorial was plagued with a int to void * conversion. While this seems to work perfectly in Windows, at least in this case, Linux users found out that it did not even compile. The code has been updated and hopefully the problem is gone. Please do report … Read more
Materials and lighting are the essence of 3D applications. These tables (1 2) show several color component combinations that can be used with either compatibility mode or the core version with a shader that emulates old OpenGL lighting model.
ShaderGen is an old tool from 3D labs, but its usefulness is not gone. The tool creates shaders that mimic the results of a set of fixed function state. There is a large set of options to define a state as available in OpenGL compatibility mode. Lighting, Fog, and all the other features that are … Read more
The Lighthouse3D OpenGL View Frustum Culling Tutorial has been ported to the new site. Bug reports and suggestions are most welcome.
This is an OpenGL 3.3 + GLSL 3.3 sample that loads and displays a 3D model with Assimp. It also uses DevIL in case the model has textures. It was based on Assimps OpenGL demo and it extends it to support OpenGL 3.3 The sample uses Texturing, Vertex Array Objects, and Uniform Blocks. Camera can … Read more
