handles

public BasicHeatMapProgram.Handles handles(com.jogamp.opengl.GL2ES2 gl)

Returns the raw GL handles for the shader program, uniforms, and attributes. Compiles and links the program, if necessary.

begin

public void begin(GlimpseContext context,
                  float xMin,
                  float xMax,
                  float yMin,
                  float yMax)

Specified by:

begin in interface DrawableTextureProgram

draw

public void draw(GlimpseContext context,
                 int mode,
                 GLEditableBuffer xyVbo,
                 GLEditableBuffer stVbo,
                 int first,
                 int count)

Specified by:

draw in interface DrawableTextureProgram

draw

public void draw(GlimpseContext context,
                 int mode,
                 int xyVbo,
                 int stVbo,
                 int first,
                 int count)

Specified by:

draw in interface DrawableTextureProgram

end

public void end(GlimpseContext context)

Specified by:

end in interface DrawableTextureProgram

dispose

public void dispose(GlimpseContext context)

Deletes the program, and resets this object to the way it was before #begin(GL3) was first called.

This object can be safely reused after being disposed, but in most cases there is no significant advantage to doing so.

Specified by:

dispose in interface DrawableTextureProgram
