renderscript

I am new to Android Renderscript. I need to write a convolution multiplication in RenderScript since the final application is going to run on Android. Data stream is going to be an image. More specifically, I am not able to write the core logic using forEach functionality, though I can do it in Java, but speed it too slow! Please help! Steve During the rsForEach call (or other Renderscript function), you can access the neighbouring pixels of the original image (or whatever type of data you are using) by binding the original image allocation to a pointer within the Renderscript where it can

For plattform independence (desktop, cloud, mobile, ...) it would be great to use OpenCL for GPGPU development when speed does matter. I know Google pushes RenderScript as an alternative, but it seems to be only be available for Android and is unlikely to be ever included in iOS. Therefore I seek for a solution to execute OpenCL code within Android Apps. prunge The only Android devices I know that support OpenCL are the ones based on the Mali T600 family of chips (article here ). They have an OpenCL SDK . Apparently it is OpenCL 1.1 full profile as well. The Nexus 10 is a device that uses such

I've been wondering if it was possible to use OpenCL for Android, find out that it wasn't possible, and dropped the subject altogether. But thanks to the blog post from january 14th on the official Android Developer blog (http://android-developers.blogspot.fr/2013/01/evolution-of-renderscript-performance.html), I discovered that parallel programming was possible since Android 4.0, thanks to RenderScript ! An API that has quite a few common features with OpenCL. What I'm wondering now is : why did Google choose to implement this new solution, instead of pushing OpenCL forward (an open

I have byte[] yuvByteArray (540x360 image captured from Camera.PreviewCallback.onPreviewFrame method and dumped into assets/yuv.bin file). I want to convert byte[] yuv to byte[] rgba array, using the following code (based on LivePreview android example). But I receive outBytes rgba array filled with zeros after forEach and copying out allocation to outBytes. What's wrong with my code? package hellorender; import android.app.Activity; import android.content.res.AssetManager; import android.graphics.Bitmap; import android.os.Bundle; import android.support.v8.renderscript.Allocation; import

Is it possible to use the Support Renderscript Library with Gradle? If so, how do you include it in your project? Tim Murray Gradle for Android has now Renderscript v8 support with only 2 lines in your build script. See answer by Austyn Mahoney . Keeping the original answer for historical purpose. Old Answer: Gradle supports native RS compilation, but not the RS support library. The reason is that the RS support library is hugely complicated compared to any other support library. The RS support library is actually a Java support library, a set of native libraries backing that Java lib,
