- Creating a Volumetric Ray Marcher
The post builds a march loop along the camera ray inside a mesh volume, sampling tiled 2D slice atlases as pseudo-3D density, accumulating opacity, and clipping to a bounding box while supporting o…

Ronja’s tutorial 046 demystifies HLSL partial derivatives: ddx and ddy measure how a value changes across 2×2 pixel quads, and fwidth combines them for screen-space-aware filtering.
Demonstrates greyscale debug views, then builds an anti-aliased step (aaStep) that widens cutoffs by one pixel’s gradient - reducing jaggy fire, toon bands, and procedural edges versus raw step().
Includes a scrolling noise fire shader comparing step, aaStep, and smoothstep.
