CG Internals published a blog article covering screen-filling rasterization using graphics hardware and modern OpenGL. The findings are applicable to OpenGL ES, Vulkan, and WebGL as well. For rendering screen-filling geometry we usually have to choose between a screen-aligned quad and a screen-aligned triangle. But - is there a difference? If so, which approach is better than the other? In this article we want to show you the differences between both approaches and offer an alternative. Following the theoretical analysis we introduce a demo program and evaluate screencasts together with multiple performance measures.
Khronos announced the conformance program for OpenGL 4.6 and Intel has successfully passed conformance tests for its GPU models for the Mesa Linux driver. For specifics on the conformant hardware you can check the list of conformant OpenGL products at the Khronos website. Learn more about these drivers and the OpenGL conformance tests and why they are important to you.
The Khronos™ Group, an open consortium of leading hardware and software companies creating advanced acceleration standards, announces the launch of the OpenGL® 4.6 Adopters Program to enable implementations to become officially conformant to the latest generation OpenGL specification. The significantly enhanced OpenGL 4.6 Conformance Test Suite used in the Adopters Program has been released in open source on GitHub to enable industry participation in testing and ongoing conformance test suite improvements. General information on Khronos Adopters Programs can be found here.
This three-day training provides a comprehensive introduction to modern OpenGL development. The course begins with basic concepts and includes all the fundamental topics needed to develop flexible, high performance OpenGL code that can run on the desktop and embedded / mobile devices. Key techniques including lighting, texturing, framebuffer objects and transformations are introduced, in a format suitable for any developer working in C or C++. For more information including how to register, or to discuss other OpenGL and related trainings offered by KDAB, please get in touch via the web page.
There is a new optimized OpenGL/Graphics Math for C. The original glm library is for C++ only (templates, namespaces, classes...). This new library is targeted to C99 but currently you can use it for C89 safely by language extensions. Almost all functions (inline versions) and parameters are documented inside related headers. Complete documentation is in progress. Feedback is welcome on the OpenGL forums.
Plumeria Smart Creator 3.3 has been released. It features an error free visual programming experience with an infinite loop AI, a crash preventer, and a syntax error blocker. New to version 3.3 is a full 3D Physics motion engine with oriented bounding boxes and spheres. It also includes the Apple Attack Pack with three free games all made entirely in PlumeriaSC 3.3. Apple Attack, which has just been released, presents Grandma Smith who is trying to vacuum her apples from her apple trees before aliens destroy them.
Remograph, providers of products and services for the computer graphics, visual simulation and 3D modeling markets, announced the release of Remo 3D v2.7. Remo 3D is an effective OpenGL-based tool for creating and modifying 3D models intended for realtime visualization. The primary file format is OpenFlight. Remo 3D is currently available for Microsoft Windows 10/8/7 and Linux. This new version 2.7 of Remo 3D brings brings a greatly improved tool for modifying a texture UV mapping, support for new OpenSceneGraph 3.5.9 and other various fixes. The full list of new features and improvements can be found in the release notes on our website.
The first two Khronos meet-ups coming up will both be in London. First up is the Khronos UK Game Dev Social on December 7th: "Meet developers working on Vulkan within Arm, Google, Imagination, Samsung and many more! Share your experiences with others in the graphics & game tech industries." The second is a Khronos London Chapter meet-up on December 12th: Come and hear speakers from Away3D, Arm, KDB, Unity and Intel talking about Vulkan, SPIR-V, OpenCL and of course WebGL. Back in the US on December 13th is the Khronos Boston Chapter meet-up covering the latet on Khronos APIs. Finally over in Sydney Australia will be the Khronos Sydney Chapter meet-up "Graphics XMAS Meeting in Pub (Art + Science + Design + Engineering)." All events require registration.
Vivid3D is a modern 3D engines built with OpenTK/OpenGL4.5 and C#. It can import 30+ format types, has a built in advanced UI lib, and is in active development. You can join the project on source-forge if you wish to help continue it's development.
