Coben Glow

Coben Glow teaches you to draw in perspective — the geometric foundation behind every convincing architectural sketch, city street, and interior scene. Whether you are a complete beginner or an illustrator looking to sharpen your fundamentals, twelve sequential lessons walk you from placing a horizon line all the way to constructing a three-point tower and a turning street corner, one guided step at a time. Each lesson places a virtual drafting sheet in your hands. Drag vanishing points, draw converging lines, tap intersection anchors, and pull depth handles — a live geometry engine checks every move against the mathematically correct answer and awards up to three stars per lesson. A coach narrates each step in plain language, and you can replay any lesson at any time to raise your star rating. Between lessons, four types of quick-fire drills sharpen your intuition without guidance. Hunt for a hidden vanishing point buried in a converging scene, estimate where the horizon falls, angle a third rail to match two given lines, or tap the true perspectively-correct midpoint of a receding wall face. Each eight-round session ends with a score, a personal best, and a bar chart of your round-by-round performance. When you are ready to build freely, the Construct editor lets you place boxes, arched gateways, and full city-block streets on a canvas in one-point, two-point, or three-point perspective mode. Drag vanishing points across the horizon, import a reference photo as a translucent underlay, toggle construction lines and a ground grid, and save as many scenes as you like to your personal library. Your complete lesson and drill history is captured in the Practice Log so you can see exactly how far your eye has come.
