简介明了直接上代码： #define PI 3.14159265 struct point { float x; float y; }; void decas(int point_count, struct point *point_v, float t, struct point *point_dst) { int r; float t1 = 1 - t; struct poin

dda直线绘制算法，理论不好描述，这里就直接贴代码了： /* Draw Line */ void line_dda(struct state *state, int x1, int y1, int x2, int y2) { float dx, dy, k, x, y; int r; int t; dx = x1 - x2; dy = y1 - y2; if (abs(dx) > a
