A Bridge Over a Pond, and Other Hard Problems

Since the last devlog the engine has learned to build with textured stone, reflect things properly, import real 3D models as voxels and render in nearly half the time. Then I built a courtyard to see if any of it held up.

How I Test a Real-Time Renderer

Renderers are very good at being slightly wrong. This is how I catch mine at it: byte-identical reference frames, a headless mode, timing runs that don't lie, and a fuzzer whose only job is to break the world.

Building a Ray-Traced Voxel World

I am building a voxel engine at 5 cm per voxel where every voxel can be dug, placed or painted, and every pixel is path traced. The hard part is the sheer amount of data. Here is how I handle it, what works, and the pond that used to render black.

The same meadow frame split into three strips: the colour-coded normals view, the image after the temporal blend alone, and the finished frame.

Why I Built My Own Engine

My voxel engine is my own, written from scratch in C# on Vulkan. Here is why, and what a frame looks like from the inside.
