+A highly optimized 2D|3D math library. Also known as OpenGL Mathematics (glm) for C. cglm provides fast and ergonomic math functions to ease graphics programming. It is community friendly – feel free to report any bugs and issues you face.
+If you're using C++, you might want to check out GLM +

+ + - Allocation-free + - Header-only + - SIMD-optimized + - API-agnostic + +--- + +### 📚 Documentation + +All functions and their parameters are documented above their declaration inside their corresponding headers.
+Alternatively, you can read the complete documentation [here](http://cglm.readthedocs.io). + +### 🔨 Building + +cglm can be used in it's entirety as a header-only library simply by including `cglm/cglm.h`. If you wish to link against it instead, it can be built using one of the supported build systems. Detailed information about building on individual platforms and build systems along with the instructions for building the documentation can be found in [BUILDING.md](./BUILDING.md). + +### ✅ Usage + +#### Header-only + +Include the `cglm/cglm.h` header and use functions with the `glm_` prefix. +```c +#include "cglm/cglm.h" + +// ... + +vec2 vector; +glm_vec2_zero(vector); +``` + +#### Struct API + +Include `cglm/struct.h` and use `glms_`. +```c +#include "cglm/struct.h" + +// ... + +vec2s vector = glms_vec2_zero(); +``` + +#### Linked + +Include `cglm/call.h` and use `glmc_`. +```c +#include "cglm/call.h" + +// ... + +vec2 vector; +glmc_vec2_zero(vector); +``` + +### ❗ Alignment + +While cglm by default aligns what's necessary, it is possible to disable this by defining `CGLM_ALL_UNALIGNED`. If you're targeting machines with any kind of SIMD support, make sure that all `vec4`, `mat4` and `mat2` arguments you pass to cglm functions are aligned to prevent unexpected crashes, alternatively use the unaligned versions if present. + +### Struct API + +The struct API works as follows (note the `s` suffix on types, `glms_` prefix on functions and `GLMS_` on constants): + +```C +#include + +mat4s mat = GLMS_MAT4_IDENTITY_INIT; +mat4s inv = glms_mat4_inv(mat); +``` + +Struct functions generally take parameters *by copy* and *return* the results rather than taking pointers and writing to out parameters. That means your variables can usually be `const`, if you're into that. + +The types used are actually unions that allow access to the same data in multiple ways. One of these involves anonymous structures available since C11. MSVC supports them in earlier versions out of the box and GCC/Clang as well if you enable `-fms-extensions`. +To explicitly enable anonymous structures `#define CGLM_USE_ANONYMOUS_STRUCT 1`, or `0` to disable them. +For backwards compatibility, you can also `#define CGLM_NO_ANONYMOUS_STRUCT` to disable them. If you don't specify explicitly, cglm will attempt a best guess based on your compiler and C version. + +### 📌 Migration notes: + +- `_dup` (duplicate) functions were renamed to `_copy`. For instance: `glm_vec_dup` -> `glm_vec3_copy`. +- OpenGL related functions were dropped to make cglm API independent. +- **[bugfix]** Euler angles had been previously implemented in reverse order (extrinsic). This was fixed to be intrinsic. +- **[major change]** Starting with **v0.4.0**, quaternions are stored as [x, y, z, w]. Previously it was [w, x, y, z]. +- **[api rename]** Starting with **v0.4.5**, `glm_simd_` functions are renamed to `glmm_`. +- **[new option]** Starting with **v0.4.5**, alignment requirements can be disabled. Read more in the documentation. +- **[major change]** Starting with **v0.5.0**, vec3 functions occupy the **glm_vec3_** namespace. This used to be **glm_vec_** in earlier versions. +- **[major change]** Starting with **v0.5.1**, `vec3` and `mat3` types are not aligned by default. +- **[major change]** Starting with **v0.7.3**, inline print functions are disabled by default in release mode to eliminate printing costs (see the Options chapter of the docs).
Colored output can be disabled (see documentation). +- **[major change]** Starting with **v0.8.3**, alternate clipspace configurations are supported. The `CGLM_FORCE_DEPTH_ZERO_TO_ONE` and `CGLM_FORCE_LEFT_HANDED` flags are provided to control clip depth and handedness. This makes it easier to incorporate cglm into projects using graphics APIs such as Vulkan or Metal. See https://cglm.readthedocs.io/en/latest/opt.html#clipspace-option-s + +### 🚀 Features + +- scalar and simd (sse, avx, neon...) optimizations +- general purpose matrix operations (mat4, mat3) +- chain matrix multiplication (square only) +- general purpose vector operations (cross, dot, rotate, proj, angle...) +- affine transformations +- matrix decomposition (extract rotation, scaling factor) +- optimized affine transform matrices (mul, rigid-body inverse) +- camera (lookat) +- projections (ortho, perspective) +- quaternions +- euler angles / yaw-pitch-roll to matrix +- extract euler angles +- frustum (extract view frustum planes, corners...) +- bounding box (AABB in Frustum (culling), crop, merge...) +- bounding sphere +- project, unproject +- easing functions +- curves +- curve interpolation helpers (SMC, deCasteljau...) +- comversion helpers from cglm types to Apple's simd library to pass cglm types to Metal GL without packing them on both sides +- ray intersection helpers +--- + + + + + + + + +
+
Like other graphics libraries (especially OpenGL), cglm uses column-major layout to keep matrices in memory.
+
 
+
While we might support row-major matrices in the future, currently if you need your matrices to be in row-major layout you have to transpose them.
+ 		+ +
+ +--- + +cglm contains general purpose mat4 product and inverse functions but also provides optimized versions for affine transformations. If you want to multiply two affine transformation matrices you can use glm_mul instead of glm_mat4_mul and glm_inv_tr (ROT + TR) instead glm_mat4_inv. +```C +/* multiplication */ +mat4 modelMat; +glm_mul(T, R, modelMat); + +/* othonormal rot + tr matrix inverse (rigid-body) */ +glm_inv_tr(modelMat); +``` + +## Contributors + +This project exists thanks to all the people who contribute.

This is especially important if you're using features like Modules in Xcode, where adding macros directly before the **cglm** headers might not work. + +Alignment Option +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +By default, **cglm** requires types to be aligned with specific byte requirements: + +- vec3: 8 bytes +- vec4: 16 bytes +- mat4: 16 bytes (32 on AVX) +- versor: 16 bytes + +Starting with **v0.4.5**, **cglm** offers an option to relax these alignment requirements. To use this option, define the **CGLM_ALL_UNALIGNED** macro before including any headers. This definition can be made within Xcode, Visual Studio, other IDEs, or directly in your build system. If using pre-compiled versions of **cglm**, you'll need to compile them with the **CGLM_ALL_UNALIGNED** macro. + +**❗️NOTE:❗️** If you're using **cglm** across multiple interdependent projects: + +- Always or never use the **CGLM_ALL_UNALIGNED** macro in all linked projects to avoid configuration conflicts. A **cglm** header from one project could require alignment, while a header from another might not, leading to **cglm** functions accessing invalid memory locations. + +- **Key Point:** Maintain the same **cglm** configuration across all your projects. For example, if you activate **CGLM_ALL_UNALIGNED** in one project, ensure it's set in the others too. + +**❗️NOTE:❗️** + +While **CGLM_ALL_UNALIGNED** allows for flexibility in alignment, it doesn't override C's fundamental alignment rules. For example, an array like *vec4* decays to a pointer (float*) in functions, which must adhere to the alignment requirements of a float pointer (4 bytes). This adherence is crucial because **cglm** directly dereferences these pointers instead of copying data, and failing to meet alignment requirements can lead to unpredictable errors, such as crashes. + +You can use `CGLM_ALIGN` and `CGLM_ALIGN_MAT` macros for aligning local variables or struct members.

If you don't want to change your existing +clipspace configuration and want to use different clipspace function like `glm_lookat_zo` or `glm_lookat_lh_zo`... +then you can include individual headers or just define `CGLM_CLIPSPACE_INCLUDE_ALL` which will include all headers for you. + +1. **CGLM_CLIPSPACE_INCLUDE_ALL** +2. **CGLM_FORCE_DEPTH_ZERO_TO_ONE** +3. **CGLM_FORCE_LEFT_HANDED** + + +1. **CGLM_CLIPSPACE_INCLUDE_ALL**: + +By defining this macro, **cglm** will include all clipspace functions for you by just using +`#include cglm/cglm.h` or `#include cglm/struct.h` or `#include cglm/call.h` + +Otherwise you need to include header you want manually e.g. `#include cglm/clipspace/view_rh_zo.h` + +2. **CGLM_FORCE_DEPTH_ZERO_TO_ONE** + +This is similar to **GLM**'s **GLM_FORCE_DEPTH_ZERO_TO_ONE** option. +This will set clip space between 0 to 1 which makes **cglm** Vulkan, Metal friendly. + +You can use functions like `glm_lookat_lh_zo()` individually.

So we may uncomment that line for Visual Studio 2017, +you may do it yourself. + +**This MSVC issue is still in TODOs.** + +**UPDATE:** Starting with v0.4.5, cglm provides an option to disable the alignment requirement. +Also, alignment is disabled for older msvc versions by default.
