 - Since I'm testing this library in my projects, sometimes bugs occurs; finding that bug[s] and making improvements would be more easy with multiple developer/contributor and their projects or knowledge. Consider to make some tests if you suspect something is wrong and any feedbacks, contributions and bug reports are always welcome.

-#### Allocations?
+#### 📌 Allocations?
 `cglm` doesn't alloc any memory on heap. So it doesn't provide any allocator. You should alloc memory for **out** parameters too if you pass pointer of memory location. Don't forget that **vec4** (also quat/**versor**) and **mat4** must be aligned (16-bytes), because *cglm* uses SIMD instructions to optimize most operations if available.

-#### Returning vector or matrix... ?

 **cglm** supports both *ARRAY API* and *STRUCT API*, so you can return structs if you utilize struct api (`glms_`).

 The types used are actually unions that allow access to the same data multiple ways. One of those ways involves anonymous structures, available since C11. MSVC also supports it for earlier C versions out of the box and GCC/Clang do if you enable `-fms-extensions`. To explicitly enable these anonymous structures, `#define CGLM_USE_ANONYMOUS_STRUCT` to `1`, to disable them, to `0`. For backward compatibility, you can also `#define CGLM_NO_ANONYMOUS_STRUCT` (value is irrelevant) to disable them.

+Clipspace Option[s]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By starting **v0.8.3** cglm provides options to switch between clipspace configurations.
+
+Clipspace related files are located at `include/cglm/[struct]/clipspace.h` but 
+these are included in related files like `cam.h`. 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 iclude 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. By setting **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
+functions in cam.h for instance will use `_zo` versions.
+
+3. **CGLM_FORCE_LEFT_HANDED**
+
+Force **cglm** to use the left handed coordinate system by default, currently **cglm** uses right handed coordinate system as default,
+you can change this behavior with this option.
+
+**VERY VERY IMPORTANT:**
+
+Be careful if you include **cglm** in multiple projects.

 SSE and SSE2 Shuffle Option
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 **_mm_shuffle_ps** generates **shufps** instruction even if registers are same.

michaelg	c013bd462c	Add LH & RH_NO perspective functions This commit adds functions `glm_perspective_lh_no` and `glm_perspective_rh_no` to the code. Unit tests are added and this commit follows the new pattern of adding the a new file per coordinate-system and clip-space tuple. . Makefile.am updated . removed test/glm_cmp project stub . unit tests include naive implementations to as well as magic number ref-data generated by the corresponding GLM functions. No tests run yet on Windows or Mac.	2021-05-13 23:18:05 +02:00
michaelg	b3a18b8a15	Add glm_perspective_rh_zo function + tests This commit adds the RH/ZO perspective function. It does so in the new file `cam_rh_zo.h` and further refactors the LH variant into new file `cam_lh_zo.h`. This creates some churn in the tests and configuration files as new test files were added as well, and all these changes found their way into the build files. Tests passing on Linux.	2021-05-13 23:18:05 +02:00
michaelg	1bce62c371	Add function glm_perspective_lh_zo This commit adds the function `glm_perspective_lh_zo`, modelled on the implementation of glm_perspective, but amended to provide a left-hand coordinate system expected by DirectX, Metal and Vulkan (per the GLM project's `glm/detail/setup.hpp`). It uses a clip-space of zero-to-one. The function is tested against a longhand version of the algorithm it seeks to implement as well as against the output of the GLM project's `glm::perspectiveLH_ZO` function. This commit adds a new subdirectory `test/glm_cmp` which contains a basic CMake file and `main.cpp`. An interested user should link or copy or clone the GLM project into this directory. The `main` function can be used to print the reference data used so others can verify behaviour in the future, or add new literal reference values.	2021-05-13 23:18:05 +02:00
