Initially populated with EGL_ANDROID_presentation_time (moved from the
EGL14 class) and the ES-relevant parts of EGL_KHR_create_context.

Updating the generator to handle GLvoid*/java.nio.Buffer return values
probably wouldn't be too hard, but this is the only function that
needs it currently.

Just a search-and-replace on the glGetActiveAttrib special-case, since
they have the same signature and parameter handling.

Some of these are new ES3 functions, some are existing ES2 functions
that can now use the new pixel pack/unpack buffer bindings.
glDrawElementsInstanced needs a special case since the pointer/offset
arg isn't the last one like the generator assumes.

Return values are declared with the C return type, but the JNI
function returns the JNI return type. In the case of GLsync/jlong as
in glFenceSync(), this causes a compile error. So the generator now
explicitly casts the return value to the JNI return type.

This change adds ES3 functions to GLES30.spec, disabling any that
require non-trivial changes for the generator to handle.
Steps taken to add these:
- Copy ES3 function declarations from gl3.h
- Remove GL_APICALL, GL_APIENTRY, and semicolon from each declaration
- Add whitespace around parens and *s as required by the parser
- Comment out functions that the generator doesn't understand or that
it generates bad Java interfaces for (by inspection).

With the addition of float framebuffer support in ES3, some parameters
to ES2 functions are now GLfloat instead of GLclampf. Both are
typedefs for 'float', so this is a source and binary compatible change.

Added EGL extension to set a timestamp on a surface.
Also, fix JNI encoding of "long" in glgen.
Bug 8191230
Change-Id: I38b7334bade3f8ff02bffe600bb74469ef22c164
- added support for comments in checks.spec
- added most missing checks
- added and commented with // special-cased functions
- added and commented with # functions that are still missing validation checks
- moved glGet* to a special case and updated all the "pnames" from the khronos spec
- changed ifcheck to default to 1 value. this allows us to simplify the checks.spec file
and handle unknown pnames automatically (they'll be validated against 1 value, if
it happens to need more, the call will go through but the validation will not
happen).
- refactored the cpp headers in to a common header + GLES version specific
header
Bug: 7402895
Change-Id: Ib5c68ca0ca416407b4cfa36e3a21901b2d6263ab
Adds support for formerly-unimplemented methods:
glCurrentPaletteMatrixOES
glLoadPaletteFromModelViewMatrixOES
glMatrixIndexPointerOES
glWeightPointerOES
The bulk of the changes are related to implementing the two PointerOES
methods, which are implemented pretty much the same way as the existing
Pointer methods were implemented.
This change also changes the way glPointSizePointerOES is implemented,
making it act like all the other Pointer methods. (Previously it was
not handling non-direct-buffer arguments correctly.)
Fixes bug 2308625 "Support matrix palette skinning
in JSR239 and related APIs"
Also updated GLLogWraper to fix two bugs in GLLogWrapper that were
discovered while testing matrix palette skinning support:
a) Handle trying to print the contents of null-but-enabled buffers.
(It's not legal to draw with null-but-enabled buffers, and
in fact some OpenGL drivers will crash if you try to render in this
state, but there's no reason the GLLogWrapper should crash while trying
to debug this situation.
b) Don't read off the end of a vertex buffer with non-zero position when
printing the entire contents of the vertex buffer. Now we only print from
the current position to the end of the buffer.
Without the size checks it's possible for calls to glBufferData
and glBufferSubData to read off the end of the Buffer object's
data, which can cause page faults.
Fix end-of-line characters for the "spec" files. (That's why
every line of these files is changed.)
Enhance our code emitter to properly handle bounds checks for
possibly-null pointers.
Remove include of an internal agl header file. We should not depend on any implementation details
of our software renderer, since they may not be correct if another renderer is used.
Fix glGet number-of-elements logic for GL_FOG_COLOR GL_LIGHT_MODEL_AMBIENT,
and GL_COMPRESSED_TEXTURE_FORMATS.
This is just plumbing. The Java APIs existed already, but there were no C APIs to hook the Java APIs
up to. Now there are C APIs, so we can call them.
Of course, whether or not the C APIs actually work when you call them depend upon the
capabilities of the active OpenGL driver, which must be checked at run time.
Also, while we're here, make the glGetString method static. It was always supposed to be static,
but was accidentally implemented as non-static, because the code was copied from the non-static
OpenGL ES classes.
This change adds four new public classes that expose a static OpenGL ES 1.1 API:
android.opengl.GLES10
android.opengl.GLES10Ext
android.opengl.GLES11
android.opengl.GLES11Ext
Benefits:
+ The static API is slightly faster (1% to 4%) than the existing Interface based JSR239 API.
+ The static API is similar to the C API, which should make it easier to import C-based
example code.
+ The static API provides a clear path for adding new OpenGL ES 1.1 extensions
and OpenGL ES 2.0 APIs, neither of which currently have a JSR standard.
Example:
import static android.opengl.GLES10.*;
...
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
Note that it is possible to mix-and-match calls to both the static and JSR239 APIs.
This works because neither API maintains state. They both call through to the same underlying
C OpenGL ES APIs.
Implementation details:
This change enhances the "glgen" "gen" script to generate both the original JSR239 and
new static OpenGL ES APIs. The contents of the generated JSR239 classes remained the same as before,
so there is no need to check in new versions of the generated JSR239 classes.
As part of this work the gen script was updated to be somewhat more robust, and to
work with git instead of perforce. The script prints out commands to git add the generated files,
but leaves it up to the script runner to actually execute those commands.
