| | | | | | | | | | | | | | | | | | bug:4351353 bug:8185479 Point tessellation is similar to line special case, except that we only tessellate one point (as a circle or rect) and duplicate it across other instances. Additionally: Fixes square caps for AA=false lines Cleanup in CanvasCompare, disabling interpolation on zoomed-in comparison view Change-Id: I0756fcc4b20f77878fed0d8057297c80e82ed9dc
* Add an on-screen overdraw counterRomain Guy2013-05-031-1/+14
| | | | | | | | | The counter can be enabled by setting the system property called debug.hwui.overdraw to the string "count". If the string is set to "show", overdraw will be highlighted on screen instead of printing out a simple counter. Change-Id: I9a9c970d54bffab43138bbb7682f6c04bc2c40bd
* Change the dither texture's swizzlingRomain Guy2013-04-091-1/+1
| | | | | | | | | | This is a more elegant way to sample from a float alpha texture. Instead of sampling from the red channel in the fragment shader we can set the alpha channel swizzle to redirect it to the red channel. This lets us sample from the alpha channel in the fragment shader and get the correct value. Change-Id: I95bbf7a82964e1bf42c0fee1b782b6bdbbcef618
* Use float textures to render gradients when possibleRomain Guy2013-04-051-48/+40
| | | | | | | | | | | Float textures offer better precision for dithering. In addition this change removes two uniforms from gradient shaders. These uniforms were used to dither gradients but their value is a build time constant. Instead we hardcode the value directly in the shader source at compile time. Change-Id: I05e9fd3eef93771843bbd91b453274452dfaefee
* Add shader program selection shortcutChris Craik2013-03-011-0/+6
| | | | | | | | | | | Add a key manipulation that makes black text/paths use the standard simple bitmap/patch shader, since they are the same. Previously we'd create a separate shader for each because the keys differed, even though the shaders were functionally equivalent. Also fixes some issues around setting DEBUG_PROGRAM Change-Id: I0c77c684d58da03501ee9ab8239c7d4a70fd6b5c
* Add new property to debug non-rectangular clip operationsRomain Guy2013-02-251-1/+7
| | | | | | | | | | | | | This change adds a new property called "debug.hwui.show_stencil_clip" that accepts the following values: - "highlight", colorizes in green any drawing command that's tested against a non-rectangular clip region - "region", shows the non-rectangular clip region in blue every time it is used - "hide", default value, nothing is shown Change-Id: I83c8602310edc4aaeb8b905371cdd185b17d32b5

* Make gradients beautiful againRomain Guy2012-09-261-7/+8
| | | | | | | | | | | | | | | | | | | Bug #7239634 This change passes two matrices to the vertex shader instead of one. We used to compute the final MVP matrix on the CPU to minimize the number of operations in the vertex shaders. Shader compilers are however smart enough to perform this optimization for us. Since we need the MV matrix to properly compute gradients dithering, this change splits the MVP matrix into two. This has the advantage of removing one matrix multiplication per drawing operation on the CPU. The SGX 540 shader compiler produces the same number of instructions in both cases. There is no penalty hit with having two matrices instead of one. We also send so few vertices per frame that it does not matter very much. Change-Id: I17d47ac4772615418e0e1885b97493d31435a936

| * Optimize shaders for dithered gradientsChet Haase2012-09-211-19/+34
| | | | | | | | | | | | | | | | | | | | | | It's faster to compute a dither calculation in the vertex shader and use a varying (letting the GPU interpolate the fragment values) than to perform that calculation in the fragment shader as part of a texture lookup.

* Fix modulation and gamma correction issuesRomain Guy2012-09-141-37/+50
| | | | | | | | | | | | | | | | | | | | | | | Modulation is normally enabled in a shader when drawing with an alpha mask (A8 texture.) Modulation is used to do one of two things: - Colorize the primitive (to draw text in red for instance) - Apply extra translucency (50% translucent circle filled with a bitmap) The current implementation has four issues: 1. Unnecessary work is performed by assigning the modulation color to vec4 fragColor early in the shader 2. The modulation color's alpha is applied twice when the primitive is drawn with an SkShader 3. The decision to modulate is wrong and triggers when any of the RGB channels is < 1.0. Only the alpha channel needs to be taken into account to make the decision 4. Gamma correction is not applied properly This change addresses all four issues above. Change-Id: I73fcc74efc4b094bf2d1b835f10ffaa2ea4b9eb9

* Varying-based AA rect drawingChris Craik2012-09-051-6/+25
| | | | | | | | | | | | Instead of calculating opacity from relative position in the shader, use a shader varying to do this computation for us. bug:5045101 Also adds a test to HwAccelerationTest to show incorrect antialiasing in scaled drawAARect / boundarySize calculation.

* New widget: TextureViewRomain Guy2011-04-281-7/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
