* Calculate and show Ambient shadow.ztenghui2013-12-131-4/+4
| | | | | | | | | Basically we compute the shadow as a strip of triangles, whose alpha value is the strength of the shadow. We use the normal to extend the geometry. And we use static function and try to avoid new/malloc in the computation. Change-Id: I382286f1cad351bd5ff983f76f446c075819dcaf

* Share Caches' index buffer with FontRendererRomain Guy2013-06-181-2/+3
| | | | | | | | | This reduces state changes when we draw 9patches and text together, which happens *a lot*. Also disable the NV profiling extension by default since it doesn't play nice with display lists deferrals. To enable it set debug.hwui.nv_profiling to true.

* Assume a texture is unbound after deleting itRomain Guy2013-06-061-1/+12
| | | | | | | | | | | Bug #9316260 The GL specification indicates that deleting a bound texture has the side effect of binding the default texture (name=0).

* Pack preloaded framework assets in a texture atlasRomain Guy2013-05-021-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the Android runtime starts, the system preloads a series of assets in the Zygote process. These assets are shared across all processes. Unfortunately, each one of these assets is later uploaded in its own OpenGL texture, once per process. This wastes memory and generates unnecessary OpenGL state changes. This CL introduces an asset server that provides an atlas to all processes. Note: bitmaps used by skia shaders are *not* sampled from the atlas. It's an uncommon use case and would require extra texture transforms in the GL shaders. WHAT IS THE ASSETS ATLAS The "assets atlas" is a single, shareable graphic buffer that contains all the system's preloaded bitmap drawables (this includes 9-patches.) The atlas is made of two distinct objects: the graphic buffer that contains the actual pixels and the map which indicates where each preloaded bitmap can be found in the atlas (essentially a pair of x and y coordinates.) HOW IS THE ASSETS ATLAS GENERATED Because we need to support a wide variety of devices and because it is easy to change the list of preloaded drawables, the atlas is generated at runtime, during the startup phase of the system process. There are several steps that lead to the atlas generation: 1. If the device is booting for the first time, or if the device was updated, we need to find the best atlas configuration. To do so, the atlas service tries a number of width, height and algorithm variations that allows us to pack as many assets as possible while using as little memory as possible. Once a best configuration is found, it gets written to disk in /data/system/framework_atlas 2. Given a best configuration (algorithm variant, dimensions and number of bitmaps that can be packed in the atlas), the atlas service packs all the preloaded bitmaps into a single graphic buffer object. 3. The packing is done using Skia in a temporary native bitmap. The Skia bitmap is then copied into the graphic buffer using OpenGL ES to benefit from texture swizzling. HOW PROCESSES USE THE ATLAS Whenever a process' hardware renderer initializes its EGL context, it queries the atlas service for the graphic buffer and the map. It is important to remember that both the context and the map will be valid for the lifetime of the hardware renderer (if the system process goes down, all apps get killed as well.) Every time the hardware renderer needs to render a bitmap, it first checks whether the bitmap can be found in the assets atlas. When the bitmap is part of the atlas, texture coordinates are remapped appropriately before rendering. Change-Id: I8eaecf53e7f6a33d90da3d0047c5ceec89ea3af0
* Introduce PixelBuffer API to enable PBOsRomain Guy2013-04-111-0/+11
| | | | | | | | | | | | | | | | | | | | | | | PBOs (Pixel Buffer Objects) can be used on OpenGL ES 3.0 to perform asynchronous texture uploads to free up the CPU. This change does not enable the use of PBOs unless a specific property is set (Adreno drivers have issues with PBOs at the moment, Mali drivers work just fine.) This change also cleans up Font/FontRenderer a little bit and improves performance of drop shadows generations by using memcpy() instead of a manual byte-by-byte copy. On GL ES 2.0 devices, or when PBOs are disabled, a PixelBuffer instance behaves like a simple byte array. The extra APIs introduced for PBOs (map/unmap and bind/unbind) are pretty much no-ops for CPU pixel buffers and won't introduce any significant overhead. This change also fixes a bug with text drop shadows: if the drop shadow is larger than the max texture size, the renderer would leave the GL context in a bad state and generate 0x501 errors. This change simply skips drop shadows if they are too large. Change-Id: I2700aadb0c6093431dc5dee3d587d689190c4e23
* Merge all shapes/paths caches to PathCacheRomain Guy2013-03-181-6/+0
| | | | | | | | | This change will greatly simplify the multi-threading of all shape types. This change also uses PathTessellator to render convex paths. Change-Id: I4e65bc95c9d24ecae2183b72204de5c2dfb6ada4
* Add TaskManager APIRomain Guy2013-03-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This API can be used to run arbitrary tasks on a pool of worker threads. The number of threads is calculated based on the number of CPU cores available. The API is made of 3 classes: TaskManager Creates and manages the worker threads. Task Describes the work to be done and the type of the output. A task contains a future used to wait for the worker thread to be done computing the result of the task. TaskProcessor The processor dispatches tasks to the TaskManager and is responsible for performing the computation required by each task. A processor will only be asked to process tasks sent to the manager through the processor. A typical use case: class MyTask: Task<MyType> class MyProcessor: TaskProcessor<MyType> TaskManager m = new TaskManager(); MyProcessor p = new MyProcessor(m); MyTask t = new MyTask(); p.add(t); // Waits until the result is available MyType result = t->getResult(); Change-Id: I1fe845ba4c49bb0e1b0627ab147f9a861c8e0749
* Precache glyphs at final raster sizeRomain Guy2013-03-011-0/+3
| | | | | | | | | | The deferred display lists model now allows us to precache glyphs at their exact size on screen. This change also removes debug markers when the renderer defers and reorders display lists. It also adds a flush event marker. Change-Id: I66ec5216dc12b93ecfdad52a7146b1cfb31fbeb4
* Add new property to debug non-rectangular clip operationsRomain Guy2013-02-251-0/+9

| * Add a RenderBuffer object to store stencil buffers.Romain Guy2013-02-071-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug #7146141 This change is needed to add a render buffer cache to avoid creating and destroying stencil buffers on every frame. This change also allows the renderer to use a 1 bit or 4 bit stencil buffer whenever possible. Finally this change fixes a bug introduced by a previous CL which causes the stencil buffer to not be updated in certain conditions. The fix relies on a new optional parameter in drawColorRects() that can be used to avoid performing a quickReject on rectangles generated by the clip region.

* Implement clipRect with a transform, clipRegion & clipPathRomain Guy2013-01-171-2/+0
| | | | | | | | | | | | | | | | | | | | | Bug #7146141 When non-rectangular clipping occurs in a layer the render buffer used as the stencil buffer is not cached. If this happens on a View's hardware layer the render buffer will live for as long as the layer is bound to the view. When a stencil buffer is required because of a call to Canvas.saveLayer() it will be allocated on every frame. A future change will address this problem. If "show GPU overdraw" is enabled, non-rectangular clips are not supported anymore and we fall back to rectangular clips instead. This is a limitation imposed by OpenGL ES that cannot be worked around at this time. This change also improves the Matrix4 implementation to easily detect when a rect remains a rect after transform.

| | | | | | | | | | | | This change improves execution of display lists, particularly on tiled renderers. The goal is to disable the scissor test as often as possible.
