+## Conclusion <a name="conclusion"></a>
+This tutorial delivered a rotating, textured cube with depth testing and
+back‑face culling. It compiled shaders that use a vertex push‑constant block
+for model‑view‑projection and model matrices, built a cube mesh and vertex
+layout, created an sRGB texture and sampler, and constructed a pipeline with
+depth and culling. Per‑frame transforms were computed and uploaded via push
+constants, and draw commands were recorded. The result demonstrates push
+constants for per‑draw transforms alongside 2D sampling in a 3D render path.

+## Conclusion <a name="conclusion"></a>
+This tutorial implemented a complete 2D sampling path. It generated a
+checkerboard on the CPU, uploaded it as an sRGB texture, created a
+linear‑clamp sampler, and defined matching binding layouts. Shaders forwarded
+UV and sampled the texture; a mesh and render pipeline were built; commands
+were recorded using a centered viewport. The result renders a textured quad
+with correct color space handling and filtering.

+## Conclusion <a name="conclusion"></a>
+This tutorial produced a spinning triangle that reads a model‑view‑projection
+matrix from a uniform buffer. The implementation aligned the shader and Rust
+layouts, created shaders and a mesh, defined a bind group layout and uniform
+buffer, built a render pipeline, wrote per‑frame matrix updates from the CPU,
+and recorded draw commands with resize‑aware projection. The result establishes
+a minimal, reusable path for per‑frame data via uniform buffers that scales to
+multiple objects and passes.
