Standard rasterization includes discrete visibility and sampling decisions that can interrupt gradients. Soft Rasterizer uses probabilistic aggregation to create a differentiable approximation. Redner computes gradients through Monte Carlo rendering and edge sampling. These methods support inverse-rendering tasks but do not guarantee unique or physically correct scene recovery from images. NeRF maps a spatial position and viewing direction to volume density and view-dependent radiance, then volume-renders along camera rays. 3D Gaussian Splatting instead optimizes explicit 3D Gaussian primitives for radiance-field rendering. These are distinct scene representations; neither makes all inverse-rendering solutions unique or physically correct.
Real-World imuse
Fit a mesh to an observed image using a rendering loss.
Use soft rasterization to provide smoother gradients near visibility boundaries.
Use edge sampling to estimate gradients at occluding edges.
Check gradient behavior for the renderer and scene configuration.

Differentiable renderers are tools for optimization, not guarantees of correct reconstruction. State the renderer, objective, and assumptions used in a result.
