A texture viewer for 3D graphics engineers

Jun 13, 2013

Pico Pixel is a texture viewer for 3D graphics developers. It can zoom in and out on details, inspect color channels and display detailed color information at any pixel. Pico pixel can navigate through the mip levels of textures (2D, cube maps and volumes). Pico Pixel uses OpenGL and GPU technology for fast image operations and smooth user interaction.

OpenGL Space Combat and Strategy Game Programming

Jun 07, 2013

Learn by doing with a series of game prototypes to demonstrate the fundamentals of OpenGL-based space combat and realtime strategy game programming. Just released, prototype 5 is focusing on 3D model integration and warp flight visualisation: -simple 3D model (spaceship) rendering with deferred lighting -Visualisation of the activated warp engines -Blurred stars depending on the actual flight direction -Red- and blueshift of the irradiated light (from visible stars and nebulas) depending on the camera view direction -Warp stripes around the spaceship.

ShaderToy web based platform for developing and teaching GLSL based shading

May 21, 2013

Shadertoy is a web based platform for developing, sharing, learning, getting inspiration and teaching GLSL based shading. Developers create shaders using a live environment that allows them to see the final results as they are coding. These creations can react to different inputs such us music, videos, time of the day, and others. Shadertoy.com also introduces a social platform, which makes it a place to give feedback, promote great work, and share creations regardless of being an industry professional or students/hobbyists. The website has been running for a couple of months and has grown rapidly with beautiful works showing a great variety of rendering techniques, from post processing effects, procedural raymarchers, raytracers and demoscene pieces to simple 2D procedural graphics.

nopper.tv hosts three more OpenGL 3 and 4 examples

May 07, 2013

There are three basic OpenGL examples available about shadow volumes, displacement mapping with screen space dependent tessellation and an erode effect using a 3D noise texture. The OpenGL Graphics Engine is extended as well and there are now four complex OpenGL examples available. All examples do have source code and assets included.
