C++ (Cpp) ExtensionSet Examples

Example #1

File: hlslSupportLib.cpp Project: Irina4ik/hlsl2glslfork

	bool found = false;

}

Example #2

File: hlslLinker.cpp Project: KonajuGames/hlsl2glslfork

static void add_extension_from_semantic(EAttribSemantic sem, ETargetVersion targetVersion, ExtensionSet& extensions)
{
	if (targetVersion == ETargetGLSL_ES_300)
	{

		if (sem == EAttrSemInstanceID)
			extensions.insert("GL_ARB_draw_instanced");
	}
}

Example #3

File: glslFunction.cpp Project: Thekla/hlsl2glslfork

void GlslFunction::addNeededExtensions (ExtensionSet& extensions, ETargetVersion version) const
{
	for (size_t i = 0; i < symbols.size(); ++i)
	{
		const GlslSymbol* s = symbols[i];
		if (s->getType() == EgstSampler2DShadow && version == ETargetGLSL_ES_100)

				extensions.insert("GL_NV_texture_array");
			else if (version < ETargetGLSL_ES_300)
				extensions.insert("GL_EXT_texture_array");
		}
	}
}

Example #4

File: extensions.cpp Project: Dagarman/mame

  std::stringstream ss;
  extensions.ForEach(
      [&ss](Extension ext) { ss << ExtensionToString(ext) << " "; });
  return ss.str();
}
