New video on the CopperSpice YouTube Channel:

CsPaint - Rendering with Vulkan

by Barbara Geller and Ansel Sermersheim

About the video:

In this video, we discuss the CsPaint library and why vector graphics rendered on the GPU are going to become more important as high DPI monitors become more common. We also explain why Vulkan can provide better performance than OpenGL.

How C++17 Benefits from Boost Libraries, Part Two

by Bartlomiej Filipek

From the article:

As you know, Boost libraries give us a vast set of handy algorithms, types and features that we don’t have in the Standard Library. Many functionalities were “ported” into core C++. For example, in C++11 we got std::regex, threading and smart pointers..

Sean Parent to keynote C++ on Sea 2020

By philsquared | Nov 21, 2019 10:41 AM | Tags: None

We're thrilled to announce that Sean Parent will be joining us as our third keynote speaker for 2020. A few things had to click in to place before we could make this announcement, so it's a big relief that we can finally let the cat out of the bag!

Sean Parent - our third keynote speaker

From the article:

Some years ago, Sean worked on Photoshop at Adobe. Apparently he liked it so much we went back to work on it again! He's also worked at Apple and Google - but many in the community know him, particularly, for raising our awareness of algorithms.
