I'm trying to fix this triangle rasterizer, but cannot make it work correctly. For some reason it only draws half of the triangles. void DrawTriangle(Point2D p0, Point2D p1, Point2D p2) { Point2D Top, Middle, Bottom; bool MiddleIsLeft; if (p0.y < p1.y) // case: 1, 2, 5 { if (p0.y < p2.y) // case: 1, 2 { if (p1.y < p2.y) // case: 1 { Top = p0; Middle = p1; Bottom = p2; MiddleIsLeft = true; } else // case: 2 { Top = p0; Middle = p2; Bottom = p1; MiddleIsLeft = false; } } else // case: 5 { Top = p2; Middle = p0; Bottom = p1; MiddleIsLeft = true; } } else // case: 3, 4, 6 { if (p0.y < p2.y) // case: 4 { Top = p1; Middle = p0; Bottom = p2; MiddleIsLeft = false; } else // case: 3, 6 { if (p1.y < p2.y) // case: 3 { Top = p1; Middle = p2; Bottom = p0; MiddleIsLeft = true; } else // case 6 { Top = p2; Middle = p1; Bottom = p0; MiddleIsLeft = false; } } } float xLeft, xRight; xLeft = xRight = Top.x; float mLeft, mRight; // Region 1 if(MiddleIsLeft) { mLeft = (Top.x - Middle.x) / (Top.y - Middle.y); mRight = (Top.x - Bottom.x) / (Top.y - Bottom.y); } else { mLeft = (Top.x - Bottom.x) / (Top.y - B
