glsurfaceview

The Setup : A RelativeLayout with a GLSurfaceView and a Button as shown in the image.. The Problem: Lets say I have other triangle models (The one in the picture being the initial model)... I wish to change the models cyclically on click of the button. Since button is on the UI thread and glSurfaceView runs on a separate thread, I don't exactly know how to pass the info/instruction to it. I know there is this thing called Handler in Android which might be useful in this case... But I need some help here.. Edit: If Handler is the right way, I need to know how to add Looper to that Handler...

What is the best way for Camera Live filters. I am recently using GPUImage Library from Link: https://github.com/CyberAgent/android-gpuimagelibrary . Than I have found SurfaceView and GLSurfaceView. Problem is: How to apply live filter to camera using SurfaceView or GLSurfaceView. Thanks in advance. DAVE This link uses Texture View https://github.com/google/grafika/blob/master/app/src/main/java/com/android/grafika/LiveCameraActivity.java This uses surface view to play a movie..u can manipulate it for live camera https://github.com/google/grafika/blob/master/app/src/main/java/com/android

Android apk 里面的画图分为2D和3D两种：2D是由 Skia 来实现的，也就是我们在框架图上看到的SGL，SGL也会调用部分 opengl 的内容来实现简单的3D效果；3D部分是由OpenGL|ES实现的，OpenGL|ES是Opengl的嵌入式版本，我们先了解一下Android apk的几种画图方式，然后再来来看一看这一整套的图形体系是怎么建立的。 首先画图都是针对提供给 应用 程序的一块内存填充 数据 ， 没去研究过一个Activity是否就对应着底层的一个surface，但是应该都是对这块surface内存进行操作。因此说穿了就是我们要么调用2D 的API画图，要么调用3D的API画图，然后将画下来的图保存在这个内存中，最后这个内存里面的内容会被Opengl渲染以后变为可以在屏幕上的像素信息。 一 、Apk应用主要关心的还是这些API的使用，在Android apk里面画图有2种方式 [2D]： 1、Simple Graphics in View 就是直接使用Android已经实现的一些画图操作，比如说images，shapes，colors，pre-defined animation等等，这些简单的画图操作实际上是由skia来提供的2D图形操作。使用这些预定义好的操作，我们可以实现诸如贴一张背景图啊，画出简单的形状，实现一些简单的动画之类的操作

I'm trying to create a GLSurfaceView that displays a map of a game area. When the player moves, the game activity calls highlightSpot, which in turn should trigger a render request. The only time I want to re-draw the view is when the player moves. However, with my current implementation, despite calling setRenderMode(RENDERMODE_WHEN_DIRTY) on my GLSurfaceView, its render mode still seems to be continuous. To check, I threw a single println statement in my onDrawFrame method, and when I run my application, the output quickly fills up my logcat without the player moving even once-- it's clearly
