Drag to orbit.","description":"The PlayStation's GPU interpolated texture coordinates in screen space, not 1/z, so large triangles swim, and its GTE handed over integer vertex positions, so edges wobble. This rasterizer does both on a 320-wide buffer. The floor is split into small cells because, like the original, it has no near-plane clipping: a triangle that reaches behind the eye is dropped whole. Drag to orbit. Auto-rotation stops after the first drag.","apis":["Canvas 2D","ImageData","Pointer Events","requestAnimationFrame","matchMedia"],"tags":["raster","3d"],"hasGlsl":false,"interaction":"Drag on the preview to orbit.
