NeoAxis Group Ltd announces a new version of the OpenGL-based universal environment for development of 3D projects NeoAxis 3D Engine 2.0. The new version will include many improvements, as well as significant changes in technology licensing. With version 2.0, one of the editions of the engine will be completely free.
Debugging OpenGL code using glGetError has always been painful, with OpenGL 4.3 the debugging oriented extension KHR_debug was added as a new core feature to simplify this task. While most driver vendors support this extension now even on older GL implementations, it’s again Apple who lacks behind. Even the next version of OS X 10.9, Mavericks, will not get anything newer than OpenGL 4.1. To stop being dependent on glGetError and being able to debug with KHR_debug even on those systems without native support for this extension, a solution was presented in form of a free userspace implementation of KHR_debug. It’s written in pure C and builds on top of glLoadGen and thus can be used with any OpenGL version and on all major operating systems.
This book is written against OpenGL 3.3 core profile and details over 40 recipes on diverse topics which allow the reader to 1) Explore current graphics programming techniques including GPU-based methods from the outlook of modern OpenGL 3.3 2) Learn how to implement GPU-based volume rendering algorithms 3) Discover how to employ GPU-based path and ray tracing 4) Create 3D mesh formats and skeletal animation with GPU skinning 5) Explore graphics elements including lights and shadows in an easy to understand manner And a lot more. In addition, the entire book source code may be downloaded from the publisher web site and run as desired. The book is also available from Amazon.
WRATH is a library to facilitate drawing user interfaces with GL in an optimized fashion. It does not address window creation or event handling for that matter. It only handles drawing and creation of objects that represent that drawing. To that end WRATH can be made to work in a variety of toolkits that allow drawing with OpenGL or OpenGL ES.
The 42th installment in a series of tutorials dedicated to promoting modern OpenGL development on Linux, with a focus on version 3.x and beyond. This tutorial shows how to improve shadow quality using a technique known as Percentage Closer Filtering.
Magnum is multiplatform 2D/3D graphics engine written in C++11 and modern OpenGL. Its goal is to simplify low-level graphics development and interaction with OpenGL using recent C++11 features and to abstract away platform-specific issues. Ported to Linux, Windows and Google Chrome Native Client, supports core profile OpenGL 2.1 through OpenGL 4.4, OpenGL ES 2.0 and OpenGL ES 3.0 along with modern extensions. Contains vector math library, modular and extensible scene graph, OpenGL-accelerated text rendering API and plugin-based media import. Magnum uses RAII principle, has OpenGL state tracking and transparent support for EXT_direct_state_access. With automatic fallback to core functionality for unsupported extensions it allows the users to develop OpenGL applications with less code and less explicit state and extension handling. The engine is licensed under MIT license.
The new 3D adventure game Shades of Sanity is the “spiritual successor” of Sanitarium including some of the DreamForge development team such as Keith Leonard from the old OpenGL Unreal port. The game is a first person 3D horror adventure game inspired by the team’s work on Sanitarium. The 3D engine is new from the ground up and uses OpenGL for rendering. We make heavy use GLSL Shaders, framebuffer_objects, conditional rendering, occlusion query, vertex buffer objects, anisotropic filtering, GLEW, geometry shaders, KHR_debug, etc…. The engine is a lighting prepass renderer with some modern features such as bokeh, bloom, real time ambient occlusion, refraction, and even deferred ray marched reflections.
