tag:github.com,2008:https://github.com/HandmadeMath/HandmadeMath/releases 2023-02-20T19:03:46Z tag:github.com,2008:Repository/49993383/v2.0.0 2023-02-20T21:32:39Z <p>After far too long, we are happy to release Handmade Math 2.0. Handmade Math 2.0 introduces the following new features and changes:</p> <ul> <li> <p><strong>A concise naming scheme.</strong> Handmade Math 1.0 has extremely verbose names. For version 2, we've reworked them to use a terse naming scheme that will make expressions much more readable. Here are some examples:</p> <ul> <li><code>HMM_MultiplyMat4ByVec4</code> -&gt; <code>HMM_MulM4V4</code></li> <li><code>HMM_MultiplyVec3f</code> -&gt; <code>HMM_MulV3F</code></li> <li><code>HMM_EqualsVec4</code> -&gt; <code>HMM_EqV4</code></li> </ul> <p>This is obviously an extremely breaking change, but to ease the transition, we provide a tool to automatically rename Handmade Math functions and types in your codebase. See the <code>update</code> folder of the repo.</p> </li> <li> <p><strong>Matrix inverses.</strong> We are happy to finally provide our most long-requested feature. We now have a variety of functions for matrix inverses.</p> </li> <li> <p><strong>2x2 and 3x3 matrices.</strong> We now provide types <code>HMM_Mat2</code> and <code>HMM_Mat3</code>.</p> </li> <li> <p><strong>C11 generics.</strong> C programmers can now use "overloaded" functions like <code>HMM_Add</code> instead of <code>HMM_AddV2</code>, <code>HMM_AddV3</code>, etc. Your expressions can now be a little more readable!</p> </li> <li> <p><strong>Consistent (and configurable) angle units.</strong> Handmade Math 1.0 used radians for some operations and degrees for others. Handmade Math 2.0 makes all functions use the same angle units - but also makes those units configurable, so you can choose to use radians, degrees, or turns across your codebase. See the documentation in <code>HandmadeMath.h</code>.</p> </li> <li> <p><strong>Left-handed and right-handed operations.</strong> Handmade Math 2.0 has both left-handed and right-handed versions of all operations where handedness applies.</p> </li> </ul> <p>This release would not be possible without the help of <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/users/dev-dwarf/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/dev-dwarf">@dev-dwarf</a>. Many thanks for his contributions!</p> <p>Other breaking changes:</p> <ul> <li>If you use Handmade Math without the standard library, the way you provide custom math functions has changed. You must now <code>#define HANDMADE_MATH_PROVIDE_MATH_FUNCTIONS</code> in addition to <code>#define HMM_SINF</code> etc.</li> <li><code>HMM_ExpF</code>, <code>HMM_LogF</code>, <code>HMM_Power</code>, and <code>HMM_PowerF</code> have been removed. They were not used internally and provided no benefit.</li> <li><code>HMM_PREFIX</code> has been removed. If you wish to use a different prefix, find and replace within <code>HandmadeMath.h</code>.</li> <li>Semi-breaking: <code>HMM_InvSqrtF</code> (formerly <code>HMM_RSquareRootF</code>) no longer does a fast inverse square root under any circumstances. It now always does a full-precision square root. This is to ensure consistent results on all platforms.</li> </ul> bvisness tag:github.com,2008:Repository/49993383/v2.0.0-rc2 2023-01-27T09:52:42Z <p><strong>This is a release candidate for Handmade Math 2.0.</strong> Please try it out and give us feedback.</p> <hr> <p>Changes from last release candidate:</p> <ul> <li>The <code>HANDMADE_MATH_USE_NDC_Z01</code> define has been removed. NDC options are now explicit in the function names, just like handedness.
