                     processing.core.PApplet pApplet)

Creates a new geometry with the geometryInfo provided.

Parameters:: geometryInfo - the geometry info; pApplet - the applet

Method Detail

setDefaultGestureActions

protected void setDefaultGestureActions()

Assigns the default gesture to this component, drag, rotate, scale.
Gets called in the constructor. Can be overridden in subclasses to allow other/more default gestures.

setBoundsBehaviour

public void setBoundsBehaviour(int boundsBehaviour)

Sets the bounds behaviour. The behaviour influences calculations in methods like getIntersectionLocal (used in picking) and getComponentContainsPointLocal. Allowed values are:

AbstractShape.BOUNDS_ONLY_CHECK
-> Uses the shape's bounding shape for the calculations
=> faster, more inaccurate
AbstractShape.BOUNDS_DONT_USE
-> Uses the shape's geometry for the calculations
=> slower, more accurate
AbstractShape.BOUNDS_CHECK_THEN_GEOMETRY_CHECK
-> Uses the shape's bounding shape first, and then also checks the geometry at picking. (Default)
=> compromise between the other two

Parameters:: boundsBehaviour - the new bounds behaviour

setBoundsPickingBehaviour

public void setBoundsPickingBehaviour(int boundsPickingBehaviour)

Deprecated. Method was renamed! Use setBoundsBehaviour()!

Sets the bounds picking behaviour.

Parameters:: boundsPickingBehaviour - the new bounds picking behaviour

setBoundingShape

public void setBoundingShape(IBoundingShape boundingShape)

Sets the bounding shape.

Parameters:: boundingShape - the new bounding shape

getBoundingShape

public IBoundingShape getBoundingShape()

Gets the bounding shape.

Returns:: the bounding shape

isBoundingShapeSet

public boolean isBoundingShapeSet()

Checks if is bounding shape set.

Returns:: true, if is bounding shape set

computeDefaultBounds

Computes a default bounding box for the shape. This gets called after setting creating a shape and its setGeometryInfo method is called.

setBoundsAutoCompute

public void setBoundsAutoCompute(boolean autoCompute)

Sets the bounds auto compute.

Parameters:: autoCompute - the new bounds auto compute

isBoundsAutoCompute

public boolean isBoundsAutoCompute()

Checks if is bounds auto compute.

Returns:: true, if is bounds auto compute

setGeometryInfo

public void setGeometryInfo(GeometryInfo geometryInfo)

Sets a new geometryInfo with new vertices for this shape.
If running in OpenGL mode, this also creates new vertex buffers for openGL use and eventually new Vertex Buffer Objects or Displaylists depending on the objects settings! So DONT create them (buffers or vbos) on the geometryinfo yourself manually, prior to setting it here!
Also calls computeDefaultBounds() if setAutoComputeBounds() is true (default) to recreate the bounding shape.
NOTE: Be aware, that an old geometryinfo of this shape may have created VBOs or displaylists on the gfx card which we should delete if not needed anywhere else!

Parameters:: geometryInfo - the geometry info

getGeometryInfo

public GeometryInfo getGeometryInfo()

Gets the geometry info. The geometryinfo contains the geometric information of this shape by managing the shapes vertices, OpenGL vertex buffer objects and OpenGL display list.

Returns:: the geometry info the geometry information object of that shape

setVertices

public void setVertices(Vertex[] vertices)

Sets new vertices for that shape. and generates new vertex arrays for opengl mode.

Re-computes and sets the shapes default bounding shape.

Parameters:: vertices - the vertices

getVerticesLocal

public Vertex[] getVerticesLocal()

Returns the vertices of this shape without any transformations applied
Caution: If you alter them in anyway, changes will only be consistent by calling the setVertices(Vertex[]) method with the changes vertices as an argument!.

Returns:: the untransformed vertices

getVerticesGlobal

public Vertex[] getVerticesGlobal()

Returns the vertices of this shape in real world (global) coordinates
Caution: If you alter them in anyway, changes will only be consistent if you call the setVertices() method of the shape.
Caution:This operation is not cheap since all vertices are first copied and then transformed!
Note: if a shape as a lot of vertices this will increase memory usage considerably because a complete copy of the shapes vertices is made and kept!

Returns:: the vertices in global coordinate space

setMatricesDirty

public void setMatricesDirty(boolean baseMatrixDirty)

Description copied from class: MTComponent

Informs the object (and its children), that its matrix - OR ONE OF ITS PARENT'S MATRIX - has been altered.

getVertexCount

public int getVertexCount()

Gets the vertex count.

Returns:: the vertex count the number of vertices for that shape

isUseDirectGL

public boolean isUseDirectGL()

Checks if is use direct gl.

Returns:: true, if checks if is use direct gl true, if the shape tries to draw itself with OpenGL commands rather than processing commands

setUseDirectGL

public void setUseDirectGL(boolean drawPureGL)

If set to true - which is the default if using the OpenGL render mode - this shape will bypass processings rendering pipeline and use the OpenGL context directly for performance increases.
Setting this to false forces the use of the processing renderer.

If this is set to true, and additionally, setUseVBOs() is set to true, the shape is drawn by using vertex buffer objects (VBO).
By calling setUseDisplayList(true) it is drawn using display lists.

Parameters:: drawPureGL - the draw pure gl

isUseVBOs

public boolean isUseVBOs()

Checks if this shape is drawn using VBOs.

Returns:: true, if checks if is use vbos true, if the shape tries to draw itself with OpenGL Vertex Buffer Objects

setUseVBOs

public void setUseVBOs(boolean useVBOs)

Tries to use Vertex Buffer Objects for displaying this shape.
You have to be in OpenGL mode and set setDrawDirectGL(true)first.

Parameters:: useVBOs - the use vb os

isUseDisplayList

public boolean isUseDisplayList()

Checks if is use display list.

Returns:: true, if checks if is use display list true, if the shape tries to draw itself with OpenGL display lists

setUseDisplayList

public void setUseDisplayList(boolean useDisplayList)

Tries to use a opengl display list for rendering this shape.
You have to be in OpenGL mode and setDrawDirectGL() has to be set to "true" first!
NOTE: the display list has to be created first to use it! This can be done by calling generateDisplayLists. Instead of these 2 steps we can also just call generateAndUseDisplayLists()
NOTE: if the shape was using a display list before we should delete it before setting a new one!

Parameters:: useDisplayList - the use display list

generateDisplayLists

public void generateDisplayLists()

Generates 2 openGL display lists for drawing this shape.
One for the interior (with textures etc.) and one for drawing the outline.
setUseDirectGL has to be set to true first!
To use the display lists for drawing, call setUseDisplayList() This method only generates them!
NOTE: if the shape was using a display list before we should delete it before setting a new one!

generateAndUseDisplayLists

public void generateAndUseDisplayLists()

Generates and uses openGL display lists for drawing this shape.

disableAndDeleteDisplayLists

public void disableAndDeleteDisplayLists()

Deletes the displaylists of the object and sets setUseDisplayList() to false.

setTexture

public void setTexture(processing.core.PImage newTexImage)

Sets a texture for this shape.
Uses the texture coordinates in the provided vertices for drawing.
If openGL mode is used, it also creates a GLTexture object.
For best compatibility, power of two texture dimensions should be provided. If the provided texture is non power of two and you are in opengl mode, we try to use the RECTANGULAR texture extension.
If textures were disabled for this component, they are being enabled again.

Parameters:: newTexImage - the new tex image

getTexture

public processing.core.PImage getTexture()

Gets the texture.

Returns:: the texture the texture object associated with this shape (either a PImage or GLTexture obj)

Returns:: the center point of this shape in untransformed local object coordinates.

destroy

public void destroy()

Removes this component from its parent.
Calls destroyComponent on this component which can be used to free resources that the component used.

Recursively calls destroy() on its children

By default, the openGl texture object and the VBOs associated with this shape will be deleted. Be careful when you share textures or VBOs across more than one object! Destroying of displaylists isnt done atm! Use disableAndDeleteDisplaylists() instead.
