What problem does it solve?

Pass per-frame data to GPU shaders using push uniforms. This approach is ideal for small, frequently changing data like time, aspect ratio, and simple matrices that drive per-frame animation.

Core Features & Use Cases

• Distinguishes push uniforms from GPU uniform buffers to select the right data path
• Defines a per-frame Uniforms struct with proper std140 alignment to match shader cbuffers
• Maps uniform slots to HLSL registers and pushes data before rendering
• Supports time-based animation, dynamic colors, and simple transform parameters

Quick Start

Define a per-frame Uniforms struct with time and aspect, populate it each frame, and push it with SDL_PushGPUVertexUniformData before beginning the render pass.
