Frustum: Cleanup / update
- Remove ctor w/ PMV, use update(..) instead - avoid API explosion
- Add update(Plane[]) to copy existing Frustum planes
- Mention world-coordinates in update(PMV)
PMVMatrix: Fix mulPMV
- P*Mv in column major order is correct for Frustum

Fix:
- Column Major Order PMV (Passing to Frustum and in calculation itself) according to paper coeff. calculation of plane
- Plane's signed distance function (only add d, don't multiply)
- Normalization: divide by lenght, not multiply

- Independent / Compile Clean
- Remove OpenMALI dependencies
- Use basic float[] type and FloatUtil

JAWTWindow.lockSurface(): Check AWT component's native peer
- Fix GLAutoDrawable.dispose(): Dispose drawable even w/o context
- It is possible to have the GLContext not being created (not made current),
so drawable shall be disposed independent.
- Merge Runnable 'postDisposeOnEDTAction' to dispose Runnable for clarity
- GLDrawableHelper: Split disposeGL from invokeGLImpl for clarity
- JAWTWindow.lockSurface(): Check AWT component's native peer
- W/o a native peer (!isDisplayable()), JAWT locking cannot succeed.
- On OSX OpenJDK 1.7, attempting to JAWT lock a peer-less component crashes the VM
- MacOSXJAWTWindow.lockSurfaceImpl(): Remove redundant null checks

b83b068c0f426f24a58e2bd9f52de9ebd0c7876d, sync GL command stream before FBO reconfig
Even though we currently have no bug experienced on this, it seems to be a good idea for
highly concurrently GL driver implementations.

destruction of drawable
Lack of finishing the GL command stream lead to a SIGSEGV on Windows w/ Nvidia driver
where probably pending GL commands were still being processed concurrently.

c002e04f848116922a1ed7bd96ead54961649bbd
As suggested by Julien Gouesse, align 'enqueue(..)' method w/ 'invoke(..)':
- public void enqueue(GLRunnable glRunnable);
+ public boolean invoke(boolean wait, List<GLRunnable> glRunnables);
|
|
|
|
|
|
| |
and after ctx/drawable swap - sync'ing GL state
Otherwise a driver crash may occur on Windows/NVidia.

(API Change) ; Added GLDrawableUtil
A GLEventListener resides in two states, initialized and uninitialized.
When added to a GLAutoDrawable, it is uninitialized.
A first 'display()' will issue GLEventListener's 'init(..)' which renders it initialized.
This is usually accompanied by 'reshape(..)' propagating the drawable's dimension.
Destruction of the GLAutoDrawable will issue GLEventListener's 'dispose(..)' which renders it uninitialized.
It turns our these means of GLEventListener controls are not sufficient in case
the user requires to remove and add them during the lifecycle and rendering of their GLAutoDrawable host.
GLAutoDrawable 'removeGLEventListener(..)' merely removes the GLEventListener from the list,
but does not complete it's lifecycle, i.e. issues 'dispose(..)' if initialized to realease GL related resources.
Hence the following essential API changes are made to complete the lifecycle:
+ public GLEventListener disposeGLEventListener(GLEventListener listener, boolean remove);
disposing a single GLEventListener, allowing it's removal from the list being optional
This is demonstrated via GLDrawableUtil.swapGLContextAndAllGLEventListener(GLAutoDrawable a, GLAutoDrawable b), see below.
++++++++
Further more the following API changes were made to expose complete control of
GLEventListener to the user:
- public void removeGLEventListener(GLEventListener listener);
+ public GLEventListener removeGLEventListener(GLEventListener listener);
The return value allows simple pipelining, and also delivers information whether
the passed listener was actually removed.
- public GLEventListener removeGLEventListener(int index) throws IndexOutOfBoundsException;
+ public int getGLEventListenerCount();
+ public GLEventListener getGLEventListener(int index) throws IndexOutOfBoundsException;
Dropping the redundant removal by index, while adding count and get methods.
+ public boolean getGLEventListenerInitState(GLEventListener listener);
+ public void setGLEventListenerInitState(GLEventListener listener, boolean initialized);
Allows retrieving and setting of listener states.
All in all these API changes allows a user to experience all freedoms in dealing w/
GLEventListeners hosted by GLAutoDrawable impl. and shall be future proof.
Note that we have avoided the Iterator pattern due to it's overhead of temporal objects creation.
The simple indexed access allows us to implement each method as an atomic operation.
+++++++++++
Further more a simple enqueue(..) method has been added, allowing to just enqueue a GLRunnable
w/o provoking it's execution - as invoke(..) does.
This method pleases a use case where GLRunnables are batched and shall be executed later on..
public boolean invoke(boolean wait, GLRunnable glRunnable);
+ public void enqueue(GLRunnable glRunnable);
+++++++++++
Added GLDrawableUtil, exposes utility function to rearrange GLEventListener, modifiy GLAutoDrawable, etc.
GLDrawableUtil.swapGLContextAndAllGLEventListener(GLAutoDrawable a, GLAutoDrawable b)
is tested and demonstrated w/ TestGLContextDrawableSwitchNEWT.
Manually tested on X11, OSX and Windows.

- Setting up default VAO for all GL >= 3.2 core ctx.
Refines commit 9b6448b1d54716fd455c0cad0c6133c0edeb3bb8
Due to GL 3.2 core spec: E.2. DEPRECATED AND REMOVED FEATURES (p 331)
"There is no more default VAO buffer 0 bound, hence generating and binding one
to avoid INVALID_OPERATION at VertexAttribPointer."
More clear is GL 4.3 core spec: 10.4 (p 307):
"An INVALID_OPERATION error is generated by any commands which
modify, draw from, or query vertex array state when no vertex array is bound.
This occurs in the initial GL state, and may occur as a result of BindVertexAr-
ray or a side effect of DeleteVertexArrays."
+++
I just have read (same spec) 2.10 (p 46/47):
"An INVALID_OPERATION error is generated if any of the *Pointer commands
specifying the location and organization of vertex array data are called while zero
is bound to the ARRAY_BUFFER buffer object binding point, and the pointer argu-
ment is not NULL."
.. which only constraints the *Pointer command use to _VBO_, not forcing a VAO.

GLContextImpl: Bind default VAO if having quirk RequiresBoundVAO.
OSX w/ OpenGL >= 3 core context implementation requires a bound VAO for vertex attribute operations,
i.e. VertexAttributePointer(..). This has been experienced on OSX 10.7.5, OpenGL 3.2 core w/ Nvidia GPU
and in several forum posts. Such 'behavior' violates the GL 3.2 core specification,
which does not state this requirement, hence it is a bug. (Please correct me if I am wrong!)
GLContextImpl works around this quirk, by generating a default VAO and binds it at 1st makeCurrent (@creation)
and deletes it at destroy. This is minimal invasive since no action is required for subsequent makeCurrent or release.
We assume if a user uses and binds a VAO herself, she will mind this quirk.
Note: We could enhance this workaround by quering for a currently bound VAO at makeCurrent() and bind our default if none.
However, we refrain from this operation to minimize the workaround and complexity.

|
|

string (for shader programs)
Uses GL_SHADING_LANGUAGE_VERSION and parses it via VersionNumber, as well as having a static fallback
using the GL context version.
The value is valid and can be retrieved after ctx has been made current once.
