Class RegionRenderer

Method Details

• create

  public static RegionRenderer create(RenderState rs, RegionRenderer.GLCallback enableCallback, RegionRenderer.GLCallback disableCallback)

  Create a Hardware accelerated Region Renderer.

  The optional RegionRenderer.GLCallbacks enableCallback and disableCallback maybe used to issue certain tasks at enable(GL2ES2, boolean).
  For example, instances defaultBlendEnable and defaultBlendDisable can be utilized to enable and disable GL.GL_BLEND.

  Parameters:

  rs - the used RenderState

  enableCallback - optional RegionRenderer.GLCallback, if not null will be issued at init(gl) and enable(gl, true).

  disableCallback - optional RegionRenderer.GLCallback, if not null will be issued at enable(gl, false).

  Returns:

  an instance of Region Renderer

  See Also:

  • enable(GL2ES2, boolean)

• isInitialized

  public final boolean isInitialized()

• getWidth

  public final int getWidth()

  Return width of current viewport

• getHeight

  public final int getHeight()

  Return height of current viewport

• getMatrix

  public final PMVMatrix getMatrix()

• isVBOSupported

  public final boolean isVBOSupported()

• init

  public final void init(GL2ES2 gl, int renderModes) throws GLException

  Initialize shader and bindings for GPU based rendering bound to the given GL object's GLContext if not initialized yet.

  Leaves the renderer enabled, ie ShaderState.

  Shall be called by a draw() method, e.g. RegionRenderer#draw(GL2ES2, Region, int)

  Parameters:

  gl - referencing the current GLContext to which the ShaderState is bound to

  renderModes -

  Throws:

  GLException - if initialization failed

• destroy

  public final void destroy(GL2ES2 gl)

• getRenderState

  public final RenderState getRenderState()

• enable

  public final void enable(GL2ES2 gl, boolean enable)

  Enabling or disabling the RenderState's shader program.

  In case enable and disable RegionRenderer.GLCallbacks are setup via create(RenderState, GLCallback, GLCallback), they will be called before toggling the shader program.

  See Also:

  • create(RenderState, GLCallback, GLCallback)

• reshapeNotify

  public final void reshapeNotify(int width, int height)

  No PMVMatrix operation is performed here. PMVMatrix is marked dirty.

• reshapePerspective

  public final void reshapePerspective(float angle, int width, int height, float near, float far)

• reshapeOrtho

  public final void reshapeOrtho(int width, int height, float near, float far)

• useShaderProgram

  public final boolean useShaderProgram(GL2ES2 gl, int renderModes, boolean pass1, int quality, int sampleCount, TextureSequence colorTexSeq)

  Parameters:

  gl -

  renderModes -

  pass1 -

  quality -

  sampleCount -

  colorTexSeq -

  Returns:

  true if a new shader program is being used and hence external uniform-data and -location, as well as the attribute-location must be updated, otherwise false.
