Constructor Detail

Glsl150ShaderGenerator

public Glsl150ShaderGenerator(AssetManager assetManager)

Creates a Glsl150ShaderGenerator

Parameters:

assetManager - the assetmanager

Method Detail

getLanguageAndVersion

protected java.lang.String getLanguageAndVersion(Shader.ShaderType type)

Description copied from class: ShaderGenerator

returns the language + version of the shader should be something like "GLSL100" for glsl 1.0 "GLSL150" for glsl 1.5.

Overrides:

getLanguageAndVersion in class Glsl100ShaderGenerator

Parameters:

type - the shader type for which the version should be returned.

Returns:

the shaderLanguage and version.

declareAttribute

protected void declareAttribute(java.lang.StringBuilder source,
                                ShaderNodeVariable var)

Declares an attribute in glsl 1.5 attributes are prefixed with the "in" keyword and not the "attribute" keyword

Overrides:

declareAttribute in class Glsl100ShaderGenerator

Parameters:

source - the StringBuilder to use

var - the variable to declare as an attribute

declareVarying

protected void declareVarying(java.lang.StringBuilder source,
                              ShaderNodeVariable var,
                              boolean input)

Declares a varying in glsl 1.5 varying are prefixed with the "in" or "out" keyword and not the "varying" keyword. "in" is used for Fragment shader (maybe Geometry shader later) "out" is used for Vertex shader (maybe Geometry shader later)

Overrides:

declareVarying in class Glsl100ShaderGenerator

Parameters:

source - the StringBuilder to use

var - the variable to declare as a varying

input - a boolean set to true if the varying is an input. This in not used in this implementation, but can be used in overriding implementations.

generateUniforms

protected void generateUniforms(java.lang.StringBuilder source,
                                ShaderGenerationInfo info,
                                Shader.ShaderType type)

Description copied from class: ShaderGenerator

generates the uniforms declaration for a shader of the given type.

Overrides:

generateUniforms in class Glsl100ShaderGenerator

Parameters:

source - the source StringBuilder to append generated code.

info - the ShaderGenerationInfo.

type - the shader type the uniforms have to be generated for.

generateStartOfMainSection

protected void generateStartOfMainSection(java.lang.StringBuilder source,
                                          ShaderGenerationInfo info,
                                          Shader.ShaderType type)

generates the start of the shader main section. this method is responsible of appending the "void main(){" in the shader and declaring all global outputs of the shader Shader outputs are declared and initialized inside the main section Fragment shader outputs are declared before the "void main(){" with the "out" keyword. after the "void main(){", the vertex output are declared and initialized and the fragment outputs are declared

Overrides:

generateStartOfMainSection in class Glsl100ShaderGenerator

Parameters:

source - the StringBuilder to append generated code.

info - the ShaderGenerationInfo.

type - the shader type the section has to be generated for.

generateEndOfMainSection

protected void generateEndOfMainSection(java.lang.StringBuilder source,
                                        ShaderGenerationInfo info,
                                        Shader.ShaderType type)

generates the end of the shader main section. this method is responsible of appending the last "}" in the shader and mapping all global outputs of the shader outputs are assigned to built in glsl output. then the main section is closed This code accounts for multi render target and correctly output to gl_FragData if several output are declared for the fragment shader only vertex shader output are mapped here, since fragment shader outputs must have been mapped in the main section.

Overrides:

generateEndOfMainSection in class Glsl100ShaderGenerator

Parameters:

source - the StringBuilder to append generated code.

info - the ShaderGenerationInfo.

type - the shader type the section has to be generated for.

initVariable

protected void initVariable(java.lang.StringBuilder source,
                            ShaderNodeVariable var,
                            java.lang.String initValue)

Append a variable initialization to the code

Parameters:

source - the StringBuilder to use

var - the variable to initialize

initValue - the init value to assign to the variable
