Dtype technology is a suite of highperformance software libraries for rendering highquality text and resolution independent scalable 2d graphics.
All we need to get a basis rasterizer working is to know how to project triangles onto the screen, convert the projected coordinates to raster space, then rasterize triangles, and potentially use a depthbuffer to solve the visibility problem. For some reason it only draws half of the triangles. Boise cascade bc framer bcframer by mitek industries should. Svg rasterizer this page describes the features of the svg rasterizer utility that comes with the batik distribution. Feb 08, 20 this still means that the triangles we softwarerasterize arent going to match up exactly with what the hardware rasterizer does, but in practice, if we mistakenly occlusioncull an object even though some of its pixel are just about visible due to subpixel coordinate differences, its not a big deal.
