Is this not the correct approach to asynchronous texture loading on Android?
Is this not the correct approach to asynchronous texture loading on Android?
Are there any transformation/conversation if I allocate texture from OpenGL application user space to some GPU internal format?
And is it possible to disable this transformation?
16 or 24 or 32bit texture
Are there any disadvantages ?
For example if I allocate…
Hello dear community members,

Hi.
Usually, I use render-to-texture technique to process the image.
However, recently, I need to read the contents to the system memory.
So, I tried to use glReadPixels as follows:
GLubyte pixels[256] = { 0, 0, 0, 0 };
GL_CHECK( glReadPixels(100, 100, 2,…
I am working on GLES program using ARM GLES3.0 Emulator ver 1.4. I could figure out that
1. glMapBufferOES fails with GL_ELEMENT_ARRAY_BUFFER as target parameter.(ref: http://community.arm.com/thread/6189)
2. Limitation section of User Guide for ARM GLES3…
Hi, I'm trying to run a benchmarking tool on the Samsung Galaxy S5 to test some optimizations and perhaps start experimenting with the use of ASTC. It seems like the GL driver is failing to create a context without an associated window to render into…
I am trying to replay GLES 3.0 traces. Following are the order of APIs

Hi Mali Devs,
We are soon releasing a HL based app and are wondering if there's a way to filter for pre ES 3.0 Mali devices (400-MP and friends). Due to the builds targeting this category using ETC1 and Mali not having a proprietary compressed texture…
Hello again!
I'm following a tutorial on (desktop) OpenGL 3.3 about gamma correction.
Basically to gain automatic gamma-corrected colors on the DESKTOP opengl we have to do:
1) Use the SRGBA texture format.
2) Use glEnable(GL_FRAMEBUFFER_SRGB) + at window…
Is it possible to debug native Android application using Mali graphics Debugger?
I have confirmed that debugging is working properly with Android Java applications, but with native C++ application (built using NDK toolchain) - debugger does not capture…
Dear All,

Hi forum,
what are the image processing techniques supported by Mali-400?
I am trying to understand the Image post processing and pre processing capabilities of Mali-400.
a simple use case is, I have input frame buffet from a camera, want to perform Image…
i was trying to develop a test case for instanced rendering. I am trying to render multiple cubes using glDrawArraysInstanced() as well as glDrawArrays().
but the offset values passed in glDrawArraysInstanced() do not give required output as obtained…
I'm doing rendering of non-color data to an RGBA4444 texture, and I'm seeing some difference in how the output from the alpha channel gets stored in the texture. It seems somehow that the alpha channel gets it's range slightly compressed, leading to higher…
Not sure if this is the right place to ask this question but how do I disable watchdog timer on my Note3 which has a Mali-T628? All I could find was dvfs stuff inside /sys/devices/platform/mali.0. Is there something in the user-mode driver I could modify…
I have a Nexus 10 with Android 5.0 and I'm getting this "error" when compiling the attached shaders :

Hi,
The tool has been terrific so far. Are there any plans to support HDR-mipmap? Is there any specific reason why the user-guide documented this so explicitly?
ASTC is great with the probe images at Light Probe Image Gallery
At the moment, to…
Have a Ubuntu 14.04 LTS and Eclipse Juno 3.7.2 (not Kepler) installed
Added the Mali Gpu Shader dvelopment plug in.
The shader configuration panel does not show up - no reaction to the selection.
This is 64bit Ubuntu on MacBookPro.
Thanks
I know that the r5p0 drivers for the Mali Midgard architecture brings up OpenGL ES 3.1 support, is there any plans in the future to support this extension?
For mobiles that don't support desktop OpenGL we are using what this extension provides to support…
