Lens Flare

Ported from Microsoft's XNA 4.0 Lens Flare sample.

Known OpenGL ES 3 / WebGL 2 limitation: the terrain and its lighting render, but the sun glow and lens flares are effectively invisible. CNA does not yet implement a precise occlusion-count fallback for these renderers. This difference from the XNA original is knowingly accepted for this gallery release.

The actual WebGL 2 result: a textured, lit mountain valley and blue sky, without the original's sun glow or lens flares.

About this sample

Move through a textured mountain landscape while a camera-facing light source changes position in the view. The original XNA version uses an occlusion query to fade a bright sun glow and ten lens-flare sprites as terrain blocks the light. The camera and terrain work here, but WebGL 2 supplies only a boolean query result; CNA's general count fallback has not yet been implemented.
