Module render 

A small software renderer for thumbnails: an isometric view of a Mesh with a z-buffer, flat shading and dark outlines where the depth jumps (silhouettes, steps), written as an RGBA PNG with a transparent background, so it sits on light and dark skins alike.

Pure Rust; the PNG is written with flate2 (zlib stream and CRC-32). Cost is bounded by the triangle count (checked by Mesh::check) and the pixel count.

Functions

png

The mesh drawn as a size × size PNG, or None for point clouds and meshes without area.
