The tech talk is the best official source of nitty-gritty details on the new chip, but I wanted to take the opportunity to add some commentary and context. The conversion from . Designed from the ground-up to be a modern API, using Vulkan can be quite difficult so you better know what you're doing if you plan to use Vulkan for your application. In a series of articles I'm going to describe how to build a simple image processing metal app. With Metal, apps can leverage a GPU to quickly render complex scenes and run computational tasks in parallel. To set it up, simply create a single view project (and have its view controller simply called ViewController, with a single UIView), and add the code from a specific example to build it. The compute kernel is as follows, in this contrived example it's taking in three 3D vectors (in both buffers). Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site To review, open the file in an editor that reveals hidden Unicode characters. Use Metal to find GPUs and perform calculations on them. To compile for OpenGL, comment out the line ' {$DEFINE METALPI}. It gives you a very basic idea of Metal computing Kernel, and show the example codes. 1 Answer. In order to tell Metal the dimensions of each threadgroup and how many threadgroups should be executed in a given compute call, we create a pair of MTLSize structs: MTLSize threadgroupCounts = MTLSizeMake (8, 8, 1); You can get started here. To calculate the partially-desaturated output color, we use a function from the Metal standard library: mix, which takes two colors and a factor between 0 and 1. Metal also allows you to sample and gather from a texture as well as get its width, height and a number of mipmap levels. For a couple of yers I've been working as iOS software engineer with a focus on GPGPU on Metal. Metal compute shader sample. Dive deeper into these frameworks and learn how to ensure a seamless experience. Select File and click on New Project. Older post Introduction to .
