Abstract
At present there is a proliferation of various computer graphics application programming
interfaces (APIs) used across various platforms. Older APIs such as OpenGL and Direct3D 9,
10, and 11 are still commonly used and have a broad base of hardware and operating system
support but have design limitations that make translating a graphical workload into commands
sent to the graphics processing unit (GPU) more complex than it needs to be. Modern APIs
including Vulkan, Direct3D 12, and Metal adopt a new approach of shifting some of the tasks
that were previously done by the manufacturer-provided driver software onto the application
using the API. In exchange, these APIs offer more direct access to the underlying hardware
where performance is less dependent on the idiosyncrasies of the driver software. Despite these
different approaches between APIs the underlying hardware between GPUs has enough
similarity that regardless of which API or platform is chosen there are common programming
patterns used. In this paper we define the structure of a new graphics API designed using
common constructs in high-level programming languages which translates calls to it to a lowerlevel
API. We then measure the performance of a sample application using the API with a pair of
different backends and compare the results with those from an implementation directly using a
lower-level API.
