About this sample

Games often draw temporary geometry to inspect collision volumes, view frustums and other otherwise invisible state. This sample supplies a reusable DebugShapeRenderer for lines, triangles, boxes, spheres and frustums.

Any part of a game can queue a shape for the next draw. A shape can last for one frame or for a chosen lifetime, after which its cached object is recycled. The renderer combines the queued lines into as few draw calls as possible while respecting XNA's Reach-profile limit.

The original marks the renderer entry points with Conditional("DEBUG"), so the visible demonstration is its original Debug configuration. This browser package keeps that exact source behavior while using optimized, symbol-free Release code generation for static hosting.
