Constructor Detail

Program

public Program(Renderer renderer)

Creates a new shader program.

Method Detail

relink

public boolean relink()

Relinks the program with its current vertex and fragment shaders.

Returns:

true if the program linked successfully, false if there was an error.

setShaders

public boolean setShaders(Shader vertex,
                          Shader fragment)

Sets the shaders for this program and links it. If linkage fails (or even if it succeeds), ShaderObject.getInfoLog() can be used to return more information.

Returns:

true if the program linked successfully, false if there was an error.

getVertexShader

public Shader getVertexShader()

Returns a reference to the vertex shader.

getFragmentShader

public Shader getFragmentShader()

Returns a reference to the fragment shader.

getUniformLocation

public int getUniformLocation(String name)

Returns the location of the identified uniform variable.

setUniforms

public void setUniforms(Program.Uniform[] uniforms)

Sets the values of the shader's uniform variables.

setAttribLocation

public void setAttribLocation(String name,
                              int index)

Binds an attribute to the specified location.

getAttribLocation

public int getAttribLocation(String name)

Returns the location of the identified attribute.
