Standard Portable Intermediate Representation (SPIR) is an intermediate language for parallel computing and graphics by Khronos Group.It is used in multiple execution environments, including the Vulkan graphics API and the OpenCL compute API, to represent a shader or kernel.
RPCS3 is a free and open-source emulator and debugger for the Sony PlayStation 3 that runs on Windows, Linux, FreeBSD and macOS operating systems, allowing PlayStation 3 games and software to be played and debugged on a personal computer.
In computer science, dynamic recompilation is a feature of some emulators and virtual machines, where the system may recompile some part of a program during execution. By compiling during execution, the system can tailor the generated code to reflect the program's run-time environment, and potentially produce more efficient code by exploiting information that is not available to a traditional ...
Shaders can be created on the fly from within an application, or read-in as text files, but must be sent to the driver in the form of a string. The set of APIs used to compile, link, and pass parameters to GLSL programs are specified in three OpenGL extensions, and became part of core OpenGL as of OpenGL Version 2.0.
Basic versions of the technique are referred to as asynchronous reprojection by Google and Valve, [1] [4] while Oculus has two implementations, called asynchronous timewarp [2] and asynchronous spacewarp. Asynchronous timewarp uses the headset's rotational data to extrapolate a new rendered frame based on the last frame it received.
The solution that the Ubershaders – in development since 2015 [77] – present to the problem was to emulate the Wii's and GameCube's rendering pipeline by way of an interpreter running on the host system's graphics processor itself until a specialized shader has been compiled and can be used for future frames, at a lower cost to performance ...
The shader assembly language in Direct3D 8 and 9 is the main programming language for vertex and pixel shaders in Shader Model 1.0/1.1, 2.0, and 3.0. It is a direct representation of the intermediate shader bytecode which is passed to the graphics driver for execution.
The API exposes seven programmable entry points within the ray tracing pipeline, allowing for custom cameras, ray-primitive intersections, shaders, shadowing, etc. This flexibility enables bidirectional path tracing, Metropolis light transport, and many other rendering algorithms that cannot be implemented with tail recursion.
