* Improve rendering performance on some GPUsRomain Guy2011-07-251-1/+1
| | | | | | | | This change sets textures filtering to GL_NEAREST by default. GL_LINEAR filtering is only used when textures are transformed with a scale or a rotation. This helps save a couple of fps on some GPUs. Change-Id: I1efaa452c2c79905f00238e54d886a37203a2ac1

* New widget: TextureViewRomain Guy2011-04-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug #4343984 TextureView can be used to render media content (video, OpenGL, RenderScript) inside a View. The key difference with SurfaceView is that TextureView does not create a new Surface. This gives the ability to seamlessly transform, animate, fade, etc. a TextureView, which was hard if not impossible to do with a SurfaceView. A TextureView also interacts perfectly with ScrollView, ListView, etc. It allows application to embed media content in a much more flexible way than before. For instance, to render the camera preview at 50% opacity, all you need to do is the following: mTextureView.setAlpha(0.5f); Camera c = Camera.open(); c.setPreviewTexture(mTextureView.getSurfaceTexture()); c.startPreview(); TextureView uses a SurfaceTexture to get the job done. More APIs are required to make it easy to create OpenGL contexts for a TextureView. It can currently be done with a bit of JNI code. Change-Id: Iaa7953097ab5beb8437bcbbfa03b2df5b7f80cd7
* Allocate layers from the layers pool.Romain Guy2011-02-021-0/+25
| | | | | | | | | | | Bug #3413433 This change will be beneficial to Launcher to avoid hiccups when swiping pages of icons. When a layer is discarded, it is kept in the layers pool instead of being destroyed right away. This favors memory reuse over allocations. Change-Id: Ifb6944ba83d6ceb67c331527c0827b26ce648eb1
* Log only 1 line per process when using OpenGLRenderer.Romain Guy2011-01-211-2/+3
| | | | Change-Id: Idbdd6b84f31301e58ed53e0d50fd61fece192dfa
* New layers API for Views.Romain Guy2011-01-061-0/+1
| | | | | | | | | This API can be used to back a view and its children with either a software layer (bitmap) or hardware layer (FBO). Layers have various usages, including color filtering and performance improvements during animations. Change-Id: Ifc3bea847918042730fc5a8c2d4206dd6c9420a3
* Tweak layers caching for better performance in Launcher.Romain Guy2010-10-121-6/+9

* Better cache for layers, reduce memory usage and increase framerate.Romain Guy2010-10-081-41/+38

* Optimize saveLayer() when the clip flag is set.Romain Guy2010-10-051-3/+13
| | | This speeds up applications, especially Launcher.
* Fix INVALID_OPERATION error with layers rendering.Romain Guy2010-10-011-0/+2
| | | | | | | | This change is a workaround for a driver bug that causes an INVALID_OPERATION to be thrown on every glCopyTexSubImage() call. This change also adds a new test for gradients local matrices. Change-Id: I41b7437481026702d0a3a9677f099b4557c0a84e
* Correctly initialize/refresh layers.Romain Guy2010-09-221-5/+3

* Better error handling in the OpenGL renderer.Romain Guy2010-09-161-2/+0
| | | | | | | Add a glGetError() check on every frame Don't attempt to create textures larger than the maximum size allowed Change-Id: Iee4afae16089406dbe8bf10fc93b674f1271a0ca
* Correct implementation of saveLayer().Romain Guy2010-09-121-23/+1

* Use only one GL context per process, share chaches.Romain Guy2010-08-241-0/+13
| | | | Change-Id: Ieabaa25338d2f4b8d4fd90e7401ad6e7452eae11
* Optimize textures binding.Romain Guy2010-07-161-1/+0
| | | | | | | The renderer is still changing textures' wrap modes every time, this will require a latter optimization. Change-Id: I3eb92cb8c886c4a692b7f0ca759911f9371d4d2c
* Create FBOs in LayerCache.Romain Guy2010-07-081-1/+47
| | | | | | | This moves a bit of code away from OpenGLRenderer and matches what happens with the TextureCache. Change-Id: I3c67f54f83d7240770daa015861c0e75a1dd8c42
* Simpler way to deal with the FBO multi-cache.Romain Guy2010-07-071-2/+3
| | | | | | | | This change removes the need for the SortedList and instead just add a generated id to each FBO stored in the cache. This is an artificial way to store several FBOs with the same dimensions. Change-Id: I9638364e9bdc0f2391261937a0c86096f20505bf
* Optimize FBO cache.Romain Guy2010-07-071-3/+2
| | | | | | | | | This change introduces a new generational cache called GenerationMultiCache that can store several values with the same key. This can be used to use multiple layers of the same size at the same time, without recreating them over and over again. Change-Id: I425466a20908b862c5f464a0f9e582ec18cbd7ac
* Add a layer (FBO) cache.Romain Guy2010-07-061-0/+114
The cache is used to draw layers so that a new texture does not have to be recreated every time a call to saveLayer() happens. The FBO cache used a KeyedVector, which is a bad idea. The cache should be able to store several FBOs of the same size (this happens a lot during scrolling with fading edges for instance.) This will be changed in a future CL.
