renderRenderParams

renderRenderParams is a data structure used to specify the configuration for a rendering run. It encapsulates the set of parameters that influence how a scene is sampled, shaded, and output during rendering. The structure is consumed by the rendering engine or by a render pipeline component to drive the rendering process.

Typical fields include resolution (width and height) and aspect ratio, samplesPerPixel or spp, maximum light bounces or depth, and options for denoising and motion blur. A reference or embedded description of the camera, exposure and white balance, and color space settings are commonly part of renderRenderParams. Additional options may cover environment lighting, the shading model, shadowing, post-processing chains, and output channels such as color, depth, or normals. Some implementations also expose flags for features like ambient occlusion, global illumination, and whether to enable progressive rendering.

Usage: renderRenderParams objects are created by applications or scripts and passed to the renderer’s render function. They may be mutable to adapt to interactive changes and can often be cloned or reset. Many engines support serialization of renderRenderParams to JSON or project files to ensure reproducibility across sessions.

Relationship and variants: renderRenderParams interacts with scene graphs, camera objects, and material systems. It is used in both biased and unbiased rendering pipelines and may be combined with render passes or compositing stages. In animation, the parameters can be animated over time to reflect changing scene conditions or rendering requirements.
