Eniko Fox in Elk: "should i do the psx colored texturing thi..."

added texturing to my affine triangle rasterizer

making a triangle rasterizer is a lot like programming language development. you make a few building blocks and then you're like "theoretically, using this, i could make anything"

and now its gouraud shaded and textured

also it makes me happy when people tell me it's a fine triangle rasterizer because that's the name of the library :3 so thank you to everyone that did so

should i do the psx colored texturing thing where medium gray is treated as 1 and white is treated as 2? in other words instead of mapping rgb 0-255 to 0-1 it treats it as 0-2, so values over 128 make the texture channels brighter, while under 128 make it darker (and 128 stays the same)

okay yeah this is way better

You can do. But remember to do the dithering after the multiplication, not before like the early PSX!

oh nooooo XD
