While mostly being very similar, +// the language syntax differ substantially in some places. Having two versions of each +// shader is clearly not an option for real projects. Maintaining intermediate representation +// that translates to both languages is one solution, but it might complicate shader development +// and debugging. +// +// HLSL converter allows HLSL shader files to be converted into GLSL source. +// The entire shader development can thus be performed using HLSL tools. Since no intermediate +// representation is used, shader files can be directly compiled by HLSL compiler. +// All tools available for HLSL shader devlopment, analysis and optimization can be +// used. The source can then be transaprently converted to GLSL. +// +// +// Using HLSL Converter +// * The following rules are used to convert HLSL texture declaration into GLSL sampler: +// - HLSL texture dimension defines GLSL sampler dimension: +// - Texture2D -> sampler2D +// - TextureCube -> samplerCube +// - HLSL texture component type defines GLSL sampler type. If no type is specified, float4 is assumed: +// - Texture2D<float> -> sampler2D +// - Texture3D<uint4> -> usampler3D +// - Texture2DArray<int2> -> isampler2DArray +// - Texture2D -> sampler2D +// - To distinguish if sampler should be shadow or not, the converter tries to find <Texture Name>_sampler +// among samplers (global variables and function arguments). If the sampler type is comparison, +// the texture is converted to shadow sampler. If sampler state is either not comparison or not found, +// regular sampler is used. +// Examples: +// - Texture2D g_ShadowMap; -> sampler2DShadow g_ShadowMap; +// SamplerComparisonState g_ShadowMap_sampler; +// - Texture2D g_Tex2D; -> sampler2D g_Tex2D; +// SamplerState g_Tex2D_sampler; +// Texture3D g_Tex3D; -> sampler3D g_Tex3D; +// +// * GLSL requires format to be specified for all images allowing writes. HLSL converter allows GLSL image +// format specification inside the special comment block: +// Example: +// RWTexture2D<float /* format=r32f */ > Tex2D; + +// Requirements: +// * Shader entry points must be declared as void functions with all outputs listed +// as out variables +// ** Members of structures cannot have system-value semantic (such as SV_Position). +// Such variables must be declared as direct shader input/output +// * GLSL allows samplers to be declared as global variables or function arguments only. +// It does not allow local variables of sampler type. +// +// Important notes/known issues: +// +// * GLSL compiler does not handle float3 structure members correctly. It is +// strongly suggested not to use this type in structure definitions +// +// * At least NVidia GLSL compiler does not apply layout(row_major) to +// structure members. By default, all matrices in both HLSL and GLSL +// are column major +// +// * GLSL compiler does not properly handle structs passed as function arguments!!!! +// struct MyStruct +// { +// matrix Matr; +// } +// void Func(in MyStruct S) +// { +// ... +// mul(f4PosWS, S.Matr); <--- This will not work!!! +// } +// DO NOT pass structs to functions, use only built-in types!!! +// +// * GLSL does not support most of the implicit type conversions. The following are some +// examples of required modifications to HLSL code: +// ** float4 vec = 0; -> float4 vec = float4(0.0, 0.0, 0.0, 0.0); +// ** float x = 0; -> float x = 0.0; +// ** uint x = 0; -> uint x = 0u; +// ** GLES is immensely strict about type conversions. For instance, +// this code will produce compiler error: float4(0, 0, 0, 0) +// It must be written as float4(0.0, 0.0, 0.0, 0.0) +// * GLSL does not support relational and boolean operations on vector types: +// ** float2 p = float2(1.0,2.0), q = float2(3.0,4.0); +// bool2 b = x < y; -> Error +// all(p<q) -> Error +// ** To facilitate relational and boolean operations on vector types, the following +// functions are predefined: +// - Less +// - LessEqual +// - Greater +// - GreaterEqual +// - Equal +// - NotEqual +// - Not +// - And +// - Or +// - BoolToFloat +// ** Examples: +// bool2 b = x < y; -> bool2 b = Less(x, y); +// all(p>=q) -> all( GreaterEqual(p,q) ) +// +// * When accessing elements of an HLSL matrix, the first index is always row: +// mat[row][column] +// In GLSL, the first index is always column: +// mat[column][row] +// MATRIX_ELEMENT(mat, row, col) macros is provided to facilitate matrix element retrieval + +// * The following functions do not have counterparts in GLSL and should be avoided: +// ** Texture2DArray.SampleCmpLevelZero() +// ** TextureCube.SampleCmpLevelZero() +// ** TextureCubeArray.SampleCmpLevelZero() + + +// * Shader converter creates shader interface blocks to process non-system generated +// input/output parameters. For instance, to process Out parameter of the vertex +// shader below +// +// struct VSOutput{ ... }; +// void VertexShader(out VSOutput Out){...} +// +// the following interface block will be created: +// +// out _IntererfaceBlock0 +// { +// VSOutput Out; +// }; +// +// OpenGL requires that interface block definitions in different shader stages +// must match exaclty: they must define the exact same variables (type/array count +// and NAME), in the exact same order. Since variable names must match, this +// effectively means that shader input/output parameter names must also match +// exactly. This limitation seems to be relaxed in desktop GL and some GLES. +// For instance, the following code works fine on Desktop GL and on Intel GLES, +// but fails on NVidia GLES: +// +// struct VSOutput{ ... }; +// void VertexShader(out VSOutput Out){...} +// void PixelShader(in VSOutput In){...} +// +// To make it run on NVidia GLES, shader intput/output parameter names must +// be exactly the same: +// +// struct VSOutput{ ... }; +// void VertexShader(out VSOutput VSOut){...} +// void PixelShader(in VSOutput VSOut){...} +// +// Moreover, even when fragment shader does not actually use the parameter, +// it still must be declared +// +// If the requirements above are not met, the shaders are still compiled successfuly, +// but glDraw*() command fails with useless error 1282 (IVALID_OPERATION)
