Apr 30 2019 Multi-dimensional strided array views in Magnum

Mag­num re­cently gained a new data struc­ture us­able for easy data de­scrip­tion, trans­form­a­tion and in­spec­tion, open­ing lots of new pos­sib­il­it­ies for more ef­fi­cient work­flows with pixel, ver­tex and an­im­a­tion data.

Mar 28 2019 Forward-declaring STL container types

Some time ago, when look­ing in­to dif­fer­ent ways how to re­duce STL head­er bloat, I dis­covered that libc++’s <iosfwd> has a for­ward de­clar­a­tion for std::vec­tor. Turns out, there are more of them — and not just on one par­tic­u­lar stand­ard lib­rary im­ple­ment­a­tion.

Mar 11 2019 Teaching VR with Magnum

Last year, Mag­num was used to in­tro­duce stu­dents to vir­tu­al real­ity pro­gram­ming at the Lud­wig-Max­imili­ans-Uni­versität München — power­ing a CAVE-like en­vir­on­ment, a room-scale five-sided pro­jec­tion in­stall­a­tion.

Feb 28 2019 How Magnum does GFX API enum mapping

En­gines sup­port­ing more than one graph­ics backend very of­ten need to trans­late vari­ous enum val­ues — pixel formats, prim­it­ive types etc. — from a gen­er­ic API-ag­nost­ic value to the one used by a par­tic­u­lar im­ple­ment­a­tion, in the fast­est-pos­sible and most ro­bust way.

Feb 18 2019 Array view implementations in Magnum

Sim­il­arly to the point­er and ref­er­ence wrap­pers de­scribed in the last art­icle, Mag­num’s ar­ray views re­cently re­ceived STL com­pat­ib­il­ity as well. Let’s take that as an op­por­tun­ity to com­pare them with the stand­ard im­ple­ment­a­tion in std::span.

Feb 05 2019 Magnum 2019.01 released

The new ver­sion puts a fo­cus on us­ab­il­ity with tweak­able con­stants for live cod­ing, Dear ImGui in­teg­ra­tion, new pack­ages, Gradle-less An­droid de­vel­op­ment, com­pile time spee­dup and oth­er gen­er­al pol­ish­ing.

Jan 16 2019 Lightweight but still STL-compatible unique pointer

Mag­num got a new unique point­er im­ple­ment­a­tion that’s much more light­weight with bet­ter de­bug per­form­ance and com­pile times, but is still fully com­pat­ible with std::unique_ptr.

Jan 03 2019 Improved Doxygen documentation and search

Wheth­er you are brows­ing Mag­num docs or use Doxy­gen for your own C++ doc­u­ment­a­tion, there’s al­ways a way to im­prove your work­flow. This art­icle presents the most re­cent ad­di­tions to the m.css Doxy­gen theme.

Oct 24 2018 Magnum 2018.10 released — with animation and Vulkan interop

Among oth­er high­lights is a new glTF play­er app, HiDPI sup­port, spline in­ter­pol­a­tion, a Box2D ex­ample and pro­ductiv­ity im­prove­ments all across the board.

Sep 05 2018 The Unnecessarily Short Ways To Do a Quaternion Slerp

Com­ing to an es­tab­lished work­flow for the first time is al­ways an in­ter­est­ing ex­per­i­ence be­cause I don’t have any “it’s been like this since forever” in­sights form­ing my opin­ion yet. This time it’s about qua­ternion in­ter­pol­a­tion and a sud­den op­tim­iz­a­tion op­por­tun­ity.
