renderscript

问题 I've seen this: https://github.com/android/platform_frameworks_support/commit/35ef270f319aeac81d562897c480b507102dc9ae And so I'm wondering when this will be available to the external 3rd party developers for general usage. Any info would be greatly appreciated. Thanks! Anthony 回答1: It is already part of the M preview and will be in the forthcoming M SDK. 来源： https://stackoverflow.com/questions/31620728/renderscript-implementation-of-blas

问题 I am now programming on Android and I wonder whether we can use GPGPU for Android now? I once heard that Renderscript can potentially execute on GPGPU in the future. But I wonder whether it is possible for us to programming on GPGPU now? And if it is possible for me to program on the Android GPGPU, where can I find some tutorials or sample programs? Thank you for your help and suggestions. Up till now I know that the OpenGL ES library was now accelerated use GPU, but I want to use the GPU for

问题 When trying to blur an image I want to use import android.support.v8.renderscript.* So I put this in my build.gradle file: android { compileSdkVersion 23 buildToolsVersion '23.0.1'" defaultConfig { minSdkVersion 14 targetSdkVersion 23 renderscriptTargetApi 18 renderscriptSupportModeEnabled true }} And I use this method to blur the image: public static Bitmap blur(Context ctx, Bitmap image) { int width = Math.round(image.getWidth() * BITMAP_SCALE); int height = Math.round(image.getHeight() *

问题 I have a problem creating an Android app that makes use of both Renderscript and native code generated with NDK. Substantially, I use NDK tools to generate a library called sprstr_native.so . I managed to call their C++ functions through Java code without problems. Then I needed some Renderscript functionalities (in particular, ScriptIntrinsicYuvToRGB ) so I've added to my Eclipse project a reference to the relative support library, renderscript-v8.jar , and this line in the project

问题 As I mentioned in my previous post (Compiling renderscript code at runtime), I try to compile renderscript code at runtime. As suggested by Kietz I need to alter the ScriptC class from which all generated java classes derive. Making my own class that extends Script fails because I cannot invoke the constructor of this super class. This snippet of the code public class RuntimeScriptC extends Script { private static final String TAG = "RuntimeScriptC"; protected RuntimeScriptC(int id,

问题 I'm following this sample in order to learn about RenderScript. I added the following at project.properties: renderscript.target=19 renderscript.support.mode=true sdk.buildtools=23.0.2 I wrote my .rs file, the ScriptC_myfilename was generated at gen folder but the android.support.v8.renderscript could not be resolved to a type, so I added the renderscript-v8.jar located at sdk/build-tools/android-4.4W/renderscript/lib as a library (configure Build Path >> Libraries >> add External JARs) and

问题 I have been creating meshes using equations, but applying texture seems to be an issue. I have created a cube and cylinder but when texture is applied, the texture is not getting allocated and only the object is visible. I created a Cylinder successfully with the help of this link - How to make a cylinder in renderscript and I've created a cube of my own. The 2 objects are visible, but not the texture applied on them. I'm able to allocate textures only for my a3d objects that I've created,
