• GlProgram

  public GlProgram​(Context context,
                   String vertexShaderFilePath,
                   String fragmentShaderFilePath)
            throws IOException,
                   GlUtil.GlException

  Deprecated.
  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.

  GlUtil.GlException

• GlProgram

  public GlProgram​(String vertexShaderGlsl,
                   String fragmentShaderGlsl)
            throws GlUtil.GlException

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

  This involves slow steps, like compiling, linking, and switching the GL program, so do not call this in fast rendering loops.

  Parameters:

  vertexShaderGlsl - The vertex shader program.

  fragmentShaderGlsl - The fragment shader program.

  Throws:

  GlUtil.GlException

Method Detail

• getUniformLocation

  public int getUniformLocation​(String uniformName)

  Deprecated.
  Returns the location of a GlProgram.Uniform.

• use

  public void use()
           throws GlUtil.GlException

  Deprecated.
  Uses the program.

  Call this in the rendering loop to switch between different programs.

  Throws:

  GlUtil.GlException

• delete

  public void delete()
              throws GlUtil.GlException

  Deprecated.
  Deletes the program. Deleted programs cannot be used again.

  Throws:

  GlUtil.GlException

• getAttributeArrayLocationAndEnable

  public int getAttributeArrayLocationAndEnable​(String attributeName)
                                         throws GlUtil.GlException

  Deprecated.
  Returns the location of an GlProgram.Attribute, which has been enabled as a vertex attribute array.

  Throws:

  GlUtil.GlException

• setBufferAttribute

  public void setBufferAttribute​(String name,
                                 float[] values,
                                 int size)

  Deprecated.
  Sets a float buffer type attribute.

• setSamplerTexIdUniform

  public void setSamplerTexIdUniform​(String name,
                                     int texId,
                                     int texUnitIndex)

  Deprecated.
  Sets a texture sampler type uniform.

  Parameters:

  name - The uniform's name.

  texId - The texture identifier.

  texUnitIndex - The texture unit index. Use a different index (0, 1, 2, ...) for each texture sampler in the program.

• setIntUniform

  public void setIntUniform​(String name,
                            int value)

  Deprecated.
