fromFiles()

static Shader* OpenGL::Shader::fromFiles ( const char *  vertex, const char *  fragment, const char *const *  attributes, int  compatGLSLVersion = 120  )

static

Creates a shader object from files

For shader files (used by games), we used to require GLSL 1.20, this is the default for compatGLSLVersion. The GLSL version is converted to GLSL ES version if needed.

Parameters

name	The name of the shader for errors messages
vertex	The vertex shader code
fragment	The fragment shader code
attributes	The vertex attributes names for indexing
compatGLSLVersion	The GLSL version required: 0 for no preprocessing, 100 for GLSL 1.00 and so on

Returns

the shader object created

fromStrings()

static Shader* OpenGL::Shader::fromStrings ( const Common::String &  name, const char *  vertex, const char *  fragment, const char *const *  attributes, int  compatGLSLVersion = 0  )

static

Creates a shader object from strings

Shader strings are usually included in backends and don't need preprocessing, this is the default for compatGLSLVersion. The GLSL version is converted to GLSL ES version if needed.

Parameters

name	The name of the shader for errors messages
vertex	The vertex shader code
fragment	The fragment shader code
attributes	The vertex attributes names for indexing
compatGLSLVersion	The GLSL version required: 0 for no preprocessing, 100 for GLSL 1.00 and so on

Returns

the shader object created

loadFromStringsArray()

bool OpenGL::Shader::loadFromStringsArray	(	const Common::String &	name,
		size_t	vertexCount,
		const char *const *	vertex,
		size_t	fragmentCount,
		const char *const *	fragment,
		const char *const *	attributes
	)

Creates a shader object from strings arrays

Everything is loaded directly without any preprocessing.

Parameters

name	The name of the shader for errors messages
vertexCount	The number of vertex shader code parts
vertex	The vertex shader code parts
fragmentCount	The number of fragment shader code parts
fragment	The fragment shader code parts
attributes	The vertex attributes names for indexing

Returns

the loading status
