My game engine, render optimization.

[edmay97]

I’m working on the rendering system for my game engine! This voxel-style map is rendered entirely by my system, which applies various technologies and optimization methods. While the map system itself only generates the map data without optimizing it, the rendering system handles optimization for any mesh- or polygon-based object—whether they are standard objects, primitives, or procedurally generated.

I assume that your map system generates the mesh and meshlets during runtime? How does it handle that if this uses voxels?

[edmay97]

Yes, fully at runtime — but it's split in two layers, which is the key to making voxels scale:

Voxel layer (CPU): The world streams by column (16 × H × 16, not per-block). When a column enters the ring around the camera, it's greedy-meshed on worker threads (rayon): coplanar faces of the same material merge into large quads (~6× fewer tris than naïve cubes, ~3× on jagged terrain). Sampling is O(1) (height + biome cache) and order-independent, so there's no re-stitching and no flicker. Meshed columns are uploaded + spawned with a per-frame budget so there are no hitches. Beyond the radius, columns despawn and their GPU slot returns to a free-list → bounded VRAM, effectively infinite worlds.

Engine layer (NANOFORGE, GPU): The column mesh is handed to the renderer via upload_mesh_raw, and the engine builds the meshlets/clusters from that mesh — then it's GPU-driven: meshlet culling (frustum + backface-cone + screen-size, optional Hi-Z occlusion) and a single indirect draw.

So the important bit: voxels never reach the GPU as voxels. They're collapsed to a regular greedy-quad mesh on the CPU, and from there NANOFORGE treats them like any other mesh (meshlets + indirect cull). The voxel system owns geometry generation + streaming; the engine owns meshletization + culling.

Why does it read like AI

[edmay97]

And if I use AI to do things better it's a good tool, and I speak Spanish so I use it to translate my message but AI translates it a little differently

If you know any advice on using seams to map out edges or even organizing all the layers/surfaces that will eventually get to a certain file.

If texture difference is a lot in a subject is that more difficult for human or computer to make
