 There are also functions to decompose transform matrix. These functions can't
 decompose matrix after projected.

+Rotation Center
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Rotating functions uses origin as rotation center (pivot/anchor point),
+since scale factors are stored in rotation matrix, same may also true for scalling.
+cglm provides some functions for rotating around at given point e.g.
+**glm_rotate_at**, **glm_quat_rotate_at**. Use them or follow next section for algorihm ("Rotate or Scale around specific Point (Pivot Point / Anchor Point)").
+
+Rotate or Scale around specific Point (Anchor Point)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to rotate model around arbibtrary point follow these steps:
+
+1. Move model from pivot point to origin: **translate(-pivot.x, -pivot.y, -pivot.z)**
+2. Apply rotation (or scaling maybe)
+3. Move model back from origin to pivot (reverse of step-1): **translate(pivot.x, pivot.y, pivot.z)**
+
+**glm_rotate_at**, **glm_quat_rotate_at** and their helper functions works that way.
+
+The implementation would be:
+
+.. code-block:: c
+  :linenos:
+
+  glm_translate(m, pivot);
+  glm_rotate(m, angle, axis);
+  glm_translate(m, pivotInv); /* pivotInv = -pivot */
+
+Transforms Order
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is important to understand this part especially if you call transform
+functions multiple times
+
+`glm_translate`, `glm_rotate`, `glm_scale` and `glm_quat_rotate` and their
+helpers functions works like this (cglm may provide reverse order too as alternative in the future):
+
+.. code-block:: c
+  :linenos:
+
+  TransformMatrix = TransformMatrix * TraslateMatrix; // glm_translate()
+  TransformMatrix = TransformMatrix * RotateMatrix;   // glm_rotate(), glm_quat_rotate()
+  TransformMatrix = TransformMatrix * ScaleMatrix;    // glm_scale()
+
+As you can see it is multipled as right matrix. For instance what will happen if you call `glm_translate` twice?
+
+.. code-block:: c
+  :linenos:
+
+  glm_translate(transform, translate1); /* transform = transform * translate1 */
+  glm_translate(transform, translate2); /* transform = transform * translate2 */
+  glm_rotate(transform, angle, axis)    /* transform = transform * rotation   */
+
+Now lets try to understand this:
+
+1. You call translate using `translate1` and you expect it will be first transform
+because you call it first, do you?
+
+Result will be **`transform = transform * translate1`**
+
+2. Then you call translate using `translate2` and you expect it will be second transform?
+
+Result will be **`transform = transform * translate2`**. Now lets expand transform,
+it was `transform * translate1` before second call.
+
+Now it is **`transform = transform * translate1 * translate2`**, now do you understand what I say?
+
+3. After last call transform will be:
+
+**`transform = transform * translate1 * translate2 * rotation`**
+
+The order will be; **rotation will be applied first**, then **translate2** then **translate1**
+
+It is all about matrix multiplication order. It is similar to MVP matrix:
+`MVP = Projection * View * Model`, model will be applied first, then view then projection.
+
+**Confused?**
+
+In the end the last function call applied first in shaders.
+
+As alternative way, you can create transform matrices individually then combine manually,
+but don't forget that `glm_translate`, `glm_rotate`, `glm_scale`... are optimized and should be faster (an smaller assembly output) than manual multiplication
+
+.. code-block:: c
+  :linenos:
+
+  mat4 transform1, transform2, transform3, finalTransform;
+
+  glm_translate_make(transform1, translate1);
+  glm_translate_make(transform2, translate2);
+  glm_rotate_make(transform3, angle, axis);
+
+  /* first apply transform1, then transform2, thentransform3 */
+  glm_mat4_mulN((mat4 *[]){&transform3, &transform2, &transform1}, 3, finalTransform);
+
+  /* if you don't want to use mulN, same as above */
+  glm_mat4_mul(transform3, transform2, finalTransform);
+  glm_mat4_mul(finalTransform, transform1, finalTransform);
+
+Now transform1 will be applied first, then transform2 then transform3

+Options
+===============================================================================
+
+A few options are provided via macros.
+
+Alignment Option
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As default, cglm requires types to be aligned. Alignment requirements:
+
+vec3:   8 byte
+vec4:   16 byte
+mat4:   16 byte
+versor: 16 byte
+
+By starting **v0.4.5** cglm provides an option to disable alignment requirement.
+To enable this option define **CGLM_ALL_UNALIGNED** macro before all headers.
+You can define it in Xcode, Visual Studio (or other IDEs) or you can also prefer
+to define it in build system. If you use pre-compiled verisons then you
+have to compile cglm with **CGLM_ALL_UNALIGNED** macro.
+
+**VERY VERY IMPORTANT:** If you use cglm in multiple projects and
+ those projects are depends on each other, then
+
+ | *ALWAYS* or *NEVER USE* **CGLM_ALL_UNALIGNED** macro in linked projects
+
+ if you do not know what you are doing. Because a cglm header included
+ via 'project A' may force types to be aligned and another cglm header
+ included via 'project B' may not require alignment. In this case
+ cglm functions will read from and write to **INVALID MEMORY LOCATIONs**.
+
+ ALWAYS USE SAME CONFIGURATION / OPTION for **cglm** if you have multiple projects.
+
+ For instance if you set CGLM_ALL_UNALIGNED in a project then set it in other projects too
+
+SSE and SSE2 Shuffle Option
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+**_mm_shuffle_ps** generates **shufps** instruction even if registers are same.
+You can force it to generate **pshufd** instruction by defining
+**CGLM_USE_INT_DOMAIN** macro. As default it is not defined.

+
+Troubleshooting
+================================================================================
+
+It is possible that sometimes you may get crashes or wrong results.
+Follow these topics
+
+Memory Allocation:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Again, **cglm** doesn't alloc any memory on heap.
+cglm functions works like memcpy; it copies data from src,
+makes calculations then copy the result to dest.
+
+You are responsible for allocation of **src** and **dest** parameters.
+
+Alignment:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**vec4** and **mat4** types requires 16 byte alignment.
+These types are marked with align attribute to let compiler know about this
+requirement.
+
+But since MSVC (Windows) throws the error:
+
+**"formal parameter with requested alignment of 16 won't be aligned"**
+
+The alignment attribute has been commented for MSVC
+
+.. code-block:: c
+
+   #if defined(_MSC_VER)
+   #  define CGLM_ALIGN(X) /* __declspec(align(X)) */
+   #else
+   #  define CGLM_ALIGN(X) __attribute((aligned(X)))
+   #endif.
+
+So MSVC may not know about alignment requirements when creating variables.
+The interesting thing is that, if I remember correctly Visual Studio 2017
+doesn't throw the above error. So we may uncomment that line for Visual Studio 2017,
+you may do it yourself.
+
+**This MSVC issue is still in TODOs.**
+
+**UPDATE:** By starting v0.4.5 cglm provides an option to disable alignment requirement.
+Also alignment is disabled for older msvc verisons as default. Now alignment is only required in Visual Studio 2017 version 15.6+ if CGLM_ALL_UNALIGNED macro is not defined.
+
+Crashes, Invalid Memory Access:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Probably you are trying to write to invalid memory location.
+
+You may used wrong function for what you want to do.
+
+For instance you may called **glm_vec4_** functions for **vec3** data type.
+It will try to write 32 byte but since **vec3** is 24 byte it should throw
+memory access error or exit the app without saying anything.
+
+Wrong Results:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Again, you may used wrong function.
+
+For instance if you use **glm_normalize()** or **glm_vec3_normalize()** for **vec4**,
+it will assume that passed param is **vec3** and will normalize it for **vec3**.
+Since you need to **vec4** to be normalized in your case, you will get wrong results.
+
+Accessing vec4 type with vec3 functions is valid, you will not get any error, exception or crash.
+You only get wrong results if you don't know what you are doing!
+
+So be carefull, when your IDE (Xcode, Visual Studio ...) tried to autocomplete function names, READ IT :)
+
+**Also implementation may be wrong please let us know by creating an issue on Github.**

Carsten Hartenfels	d3c50147cb	Replace non-standard M_PI* constants with literals M_PI, M_PI_2 and M_PI_4 aren't part of the C standard. If you put your gcc into strict standards mode, like `-std=c11`, you won't get these constants and including cglm.h will fail. This commit replaces those constants with their literal values. The cast to a float remains, to keep exactly the same behavior as before.	2018-09-19 20:42:05 +02:00
