convertToGLSL130

public static java.lang.String convertToGLSL130(java.lang.String input,
                                                boolean isFrag)

typesMatch

public static boolean typesMatch(VariableMapping mapping)

Check if a mapping is valid by checking the types and swizzle of both of the variables

Parameters:

mapping - the mapping

Returns:

true if this mapping is valid

multiplicityMatch

public static boolean multiplicityMatch(VariableMapping mapping)

Check if a mapping is valid by checking the multiplicity of both of the variables if they are arrays

Parameters:

mapping - the mapping

Returns:

true if this mapping is valid

getCardinality

                                 java.lang.String swizzling)

return the cardinality of a type and a swizzle example : vec4 cardinality is 4 float cardinality is 1 vec4.xyz cardinality is 3. sampler2D cardinality is 0

Parameters:

type - the glsl type

swizzling - the swizzling of a variable

Returns:

the cardinality

isSwizzlable

public static boolean isSwizzlable(java.lang.String type)

returns true if a variable of the given type can have a swizzle

Parameters:

type - the glsl type

Returns:

true if a variable of the given type can have a swizzle
