Graphics API Reference
Explore the comprehensive set of APIs for developing high-performance graphics and compute applications on Windows and other platforms.
Introduction to Graphics APIs
This section provides an overview of the primary graphics APIs available, their strengths, and common use cases. Understanding these foundational technologies is crucial for efficient graphics development.
DirectX (Direct3D)
Microsoft's flagship graphics API, offering low-level hardware access for maximum performance on Windows. Ideal for game development and demanding visualization tasks.
- Direct3D 12: The latest iteration, providing unprecedented control over the GPU, multithreaded command generation, and reduced CPU overhead.
- Direct3D 11: Still widely used for its robustness and extensive feature set, offering a good balance between performance and ease of use.
Vulkan
A modern, cross-platform graphics and compute API that provides high-throughput, low-latency rendering. Developed by the Khronos Group, it's a popular choice for mobile and desktop applications seeking maximum portability and control.
OpenGL
The venerable, cross-platform graphics API. While often seen as higher-level than Vulkan or DirectX 12, it remains a powerful and widely supported standard, particularly in professional applications and embedded systems.
GPU Compute APIs
Leverage the parallel processing power of your GPU for general-purpose computations beyond graphics rendering.
DirectCompute
Microsoft's compute API, integrated within DirectX. Enables parallel computation on the GPU using HLSL shaders.
OpenCL
An open standard for parallel programming of heterogeneous systems. Works across CPUs, GPUs, and other processors.
Shader Languages
Write custom programs that run on the GPU to define how objects are rendered or how computations are performed.
High-Level Shading Language (HLSL)
The shader language used with DirectX. Powerful and feature-rich for creating complex visual effects.
GLSL (OpenGL Shading Language)
The shader language for OpenGL. Similar in concept to HLSL but tailored for the OpenGL pipeline.
