Constructor Detail

• Program

  public Program​(String vertexShaderGlsl,
                 String fragmentShaderGlsl)

  Compiles a GL shader program from vertex and fragment shader GLSL GLES20 code.

  Parameters:

  vertexShaderGlsl - The vertex shader program.

  fragmentShaderGlsl - The fragment shader program.

• Program

  public Program​(Context context,
                 String vertexShaderFilePath,
                 String fragmentShaderFilePath)
          throws IOException

  Compiles a GL shader program from vertex and fragment shader GLSL GLES20 code.

  Parameters:

  context - The Context.

  vertexShaderFilePath - The path to a vertex shader program.

  fragmentShaderFilePath - The path to a fragment shader program.

  Throws:

  IOException - When failing to read shader files.

• Program

  public Program​(String[] vertexShaderGlsl,
                 String[] fragmentShaderGlsl)

  Compiles a GL shader program from vertex and fragment shader GLSL GLES20 code.

  Parameters:

  vertexShaderGlsl - The vertex shader program as arrays of strings. Strings are joined by adding a new line character in between each of them.

  fragmentShaderGlsl - The fragment shader program as arrays of strings. Strings are joined by adding a new line character in between each of them.
