Overview of Qt3D 2.0 – Part 3 - Shadow Mapping

Jan 22, 2015 | Categories: Developers | Applications | Comments

KDAB are rewriting the Qt3D module of Qt 5 to provide an easy but flexible API for easily getting 3D content into your Qt applications using either C++ or QML. Qt3D is built on top of OpenGL and OpenGL ES and provides a data-driven renderer configuration. One of the biggest driving factors behind the design of Qt3D 2.0 is the ability to configure the renderer in order to accommodate custom rendering techniques. In this blog post I will explain how to render a scene in Qt3D with shadows.

NVIDIA has provided OpenGL and OpenGL ES examples

Jan 21, 2015 | Categories: Developers | Comments

NVIDIA has provided a set of OpenGL and OpenGL ES examples illustrating various techniques and features to use in your own code. The GameWorks examples are aimed more at game developers, and run on Windows, Linux and Android. They are broken down by topic. The “NVIDIA Professional Visualization” set of examples are OpenGL based, and aimed more at the professional workstation developers.
