I try to test an app that has a GLES 3.0 renderer using the Android Studio emulator on my MX Linux O.S (Debian derivative). I selected a Pixel 3 Android 30 virtual device. The options available for the graphics are…
I'm trying to use a software (Paraview) in client/server mode opening the client on my desktop machine (linux, debian 10) and do the heavy computations on a remote server (linux, CentOS 8). The software requires OpenGL 3.2 or later implementation…

Whenever I draw a texture that has alpha around the edges (it is anti-aliased by photoshop), these edges become dark. I have endlessly messed around with texture filters and blend modes but have had no success. Here is what I…
I'm working on a project with ARKit and I'm trying to do a perspective correction of the ARFrame.capturedImage to orient a piece of paper sitting on a detected plane so I can feed that into a CoreML model which expects…
I wish to combine two textures in a shader exactly the same as you would expect from a photoshop like program. That is, one texture ontop of another as if layered. Both textures will have alpha, and the result output…
Using GPUImage I am trying to replicate Photoshop Lighten Blend Mode with opacity. Unfortunately the alpha channel has no effect using the GPUImageLightenBlendFilter. Brad confirms there might problems with alpha: GPUImage's GPUImageOpacityFilter not behaving as expected, doesn't change alpha channel…
Recently we noticed that we can load about 50 2448 x 3264 (iphone camera size) images into UIImageViews that are on the screen and currently visible. So all 50 images are decoded. We know on iphone memory size per app…
