Distorted Android

Preparation for drawing only the FRONT side of the cubit walls.

Extra API for QuatHelper.

Up version to 1.9.3

Minor.

Switch off the OpenGL error debug.

Important bugfix for the 'cube disappears when its mesh gets changed from nice to simple'.

The reason why recreating an InternalBuffer from within the 'create()' function doesn't work but doing the same from 'createImmediately' does work is not fully understood. Nevertheless the fix is correct in the sense that it...

Correct the glBufferData's usage argument: in UBO and VBO cases, it should be GL_STATIC_DRAW.

Add DistortedProgram.stopUsingProgram()

Add a glGetError() call to the main render loop.

Minor.

Add info about FPS.

Progress replacing the enum ObjetType with the class RubikObjectList.

Adjust ShapeChanging so that it can handle concave cubit faces.
Now it is working also in case of the Ivy corner cubits.

Float vertices - scratchbook

Bugfix.

Add to MeshPolygon a special modee to create a 2-band polygon with dense corners (needed to reduce number of vertices in side faces of the TwisttyPuzzle cubits)

Add testing of MeshPolygon to the MeshFile app.

Major change: separate the notion of a TwistyObject and its Node. Now,

1) the Node stays when we change objects (this makes transitions faster)
2) it's possible to just create an Object without adding it to the Screen (now app needs to explicitly create the Node and add it to its Screen itself)

Correction

By default, do use Halo Depth (this broke the halo around a solved object in distorted-cube!)

Set possibility for the Postprocessing effects to eclipse the whole object or only work at the edges.

New API: set components centers of all components all in one go.

New BORDER effect.
