/**
|
||||||
|
* GLSL to C++ stubs.
|
||||||
|
*
|
||||||
|
* The goal of this header is to make the GLSL source file compile using a modern C++ compiler.
|
||||||
|
* This allows for linting and IDE functionalities to work.
|
||||||
|
*
|
||||||
|
* This file can be included inside any GLSL file to make the GLSL syntax to work. Then your IDE
|
||||||
|
* must to be configured to associate .glsl files to C++ so that the C++ linter does the analysis.
|
||||||
|
*
|
||||||
|
* This is why the implementation of each function is not needed. However, we make sure that type
|
||||||
|
* casting is always explicit. This is because implicit casts are not always supported on all
|
||||||
|
* implementations.
|
||||||
|
*
|
||||||
|
* Float types are set to double to accept float literals without trailing f and avoid casting
|
||||||
|
* issues.
|
||||||
|
*
|
||||||
|
* Some of the features of GLSL are omitted by design. They are either:
|
||||||
|
* - not needed (e.g. per component matrix multiplication)
|
||||||
|
* - against our code-style (e.g. stpq swizzle)
|
||||||
|
* - unsupported by our Metal Shading Language layer (e.g. mixed vector-scalar matrix constructor).
|
||||||
|
*
|
||||||
|
* IMPORTANT: Please ask the module team if you need some feature that are not listed in this file.
