Use-case Mirror Android Screen to PC using USB Potential (Native) Implementation Approaches Using Android Open-Source, modify screenrecord for your needs and re-install on your Android device using ADB Use well known native API such as OpenGL / OpenMAX to capture screen Discussion Approach #1 will certainly work ( under the shell account ), however , each time the Android OS is updated, the custom code will need to get updated to keep up with OS changes, with approach #2 the API stay fixed and there is no need to worry about OS changes, the question is whether it is possible to implement

Whenever I attempt to render a textured quad, I end up with a triangular section of the texture distorted: . The texture is a PNG created in GIMP, and I've tried two seperate methods of loading the texture (both from Apple's own sample code). Each method of loading the texture produced different results (I don't know if it is different default settings, or if there is a problem with the texture), but I couldn't get either to render proper. I've tried setting up my indices/verticles/texices in multiple different ways, from suggestions posted in Fastest way to draw quads in OpenGL ES? yet still

I have a problem with very low rendering time on an android tablet using the NDK and the egl commands. I have timed calls to eglSwapBuffers and is taking a variable amount of time, frequently exceeded the device frame rate. I know it synchronizes to the refresh, but that is around 60FPS, and the times here drop well below that. The only command I issue between calls to swap is glClear , so I know it isn't anything that I'm drawing causing the problem. Even just by clearing the frame rate drops to 30FPS (erratic though). On the same device a simple GL program in Java easily renders at 60FPS,

Ok I have this code @Override public void render() { // do not update game world when paused if (!paused) { // Update game world by the time that has passed // since last render frame worldController.update(Gdx.graphics.getDeltaTime()); } // Sets the clear screen color to: Cornflower Blue Gdx.gl.glClearColor(0x64/255.0f, 0x95/255.0f, 0xed/255.0f, 0xff/255.0f); // Clears the screen Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); // Render game world to screen worldRenderer.render(); } And it draws a light blue background onto the screen. I am attempting to create a gradient that goes from a dark blue

I found a 3D graphics framework for Android called Rajawali and I am learning how to use it. I followed the most basic tutorial which is rendering a shpere object with a 1024x512 size jpg image for the texture. It worked fine on Galaxy Nexus, but it didn't work on the Galaxy Player GB70. When I say it didn't work, I mean that the object appears but the texture is not rendered. Eventually, I changed some parameters that I use for the Rajawali framework when creating textures and got it to work. Here is what I found out. The cause was coming from where the GL_TEXTURE_MIN_FILTER was being set.

I can't find the glTexImage3D() function from OpenGL in OpenGL ES 2.0. So how can I use a 3-D texture, eg: a .tga file? Does someone know how to use a 3-D texture in OpenGL ES 2.0? OpenGL ES 1.x and 2.x doesn't mandate support for 3d textures — see e.g. the canonical man page for glBindTexture , which lists only GL_TEXTURE_2D and GL_TEXTURE_CUBE_MAP as targets — and the iOS hardware doesn't provide any suitable extension. The best solution I've been able to come up with is packing a 3d texture as though it were a 2d texture, so you've got say a 128x128x128 3d texture and you lay it out as 128

I have a 3D scene and a camera defined using gluPerspective . I have a fixed FOV, and I know the minimum distance of any geometry to the camera (it is a first-person view, so that is the minimum distance from the viewpoint to the character's collision volume). How can I choose the farthest near clip plane (for the best depth buffer resolution) which will will not cause any clipping , no matter how the player moves and looks? These distances are not simply equal because the corners of the near plane are farther from the origin than the center. Formula: nearPlane = nearestApproachToPlayer / sqrt
