Detailed Description

3D Math Texture Array

3D Math Texture Array renders a spinning 3×3×3 lattice of textured cubes. It uses the same CPU-side 3D path as 3dmath_cube, then adds PNG loading, software UV sampling, and scene-wide face sorting. The software framebuffer defaults to 1280x720 and its Vulkan sprite is stretched to fit the window. Use --framebuffer WidthxHeight to override it.

Controls

• Escape - quit
• Mouse wheel - zoom in or out

Inputs

• --filename <file.png> or --texture <file.png> - texture image for the cubes
• --framebuffer <WidthxHeight> - internal software-rendering resolution

How It Works

The example transforms and rasterizes 27 cubes in software, sorts all visible faces back-to-front, samples the selected PNG texture per triangle, and uploads the resulting frame as a sprite. The entire lattice continues spinning while the mouse wheel changes the camera distance.
