What problem does it solve?

Rendering 3D geometry with correct depth ordering, perspective projection, and responsive window handling can be complex without a structured MVP pipeline and proper depth-testing. This skill provides a complete setup for depth buffers, 3D transforms, and back-face culling in SDL3 GPU, enabling robust 3D rendering workflows.

Core Features & Use Cases

• Sets up a full Model-View-Projection pipeline with mat4_multiply, mat4_look_at, and mat4_perspective
• Enables depth testing and depth writes to ensure proper occlusion
• Configures back-face culling and handling of window resize for depth textures
• Demonstrates converting 2D concepts to 3D MVP workflow and camera setup

Quick Start

Create a 3D scene with a camera and a cube, wire up a perspective projection, and enable depth testing to render correctly.
