ShaderDaten

ShaderDaten refers to the data consumed by shader programs in modern graphics pipelines. It includes inputs and resources that shaders read during rendering or computation, such as per-vertex attributes, uniform data, textures, and buffers. The term emphasizes that shader functionality depends on well-structured data supplied by the application.

Key components are: vertex attributes (such as position, normal, and texture coordinates), uniform data (transformation matrices, lighting parameters) that remain constant for a draw call or batch, textures and samplers providing image data, and buffer resources such as uniform buffers (UBO) and storage buffers (SSBO) that hold structured or large data sets. Push constants or root constants provide small, rapidly changing data with minimal overhead, where supported.

Data organization and memory layout are important for performance. Uniform buffer objects in OpenGL and analogous uniform blocks in DirectX and Vulkan enable grouping of related uniforms, with layout rules such as std140 or std430 guiding alignment and padding. Resource bindings—binding points, descriptor sets, and layouts—determine how shaderDaten is accessed by shaders and how the CPU-side code updates it.

In practice, shaderDaten flows from the application to the GPU through API calls that bind buffers, textures, and samplers to shader stages. Efficient access patterns, careful buffering, and proper alignment reduce bandwidth and improve cache utilization. ShaderDaten is central to effects such as lighting, skinning, post-processing, and compute tasks.
