你能指点我一篇关于视线渲染算法的文章吗?我正在寻找类似于Commandos系列游戏(由Pyro Studios)使用的东西。必须渲染视线锥/三角形(在俯视图中),并且由障碍物引起适当的阴影。 感谢

在伪代码中:
function get_visible_objects(observer)
/* get the list of objects inside the cone of vision */
in_cone = get_the_objects_inside(observer.cone)
/* sort the objects by proximity to the observer */
sorted = in_cone.sort_by_distance_to(observer)
/* visible is the result. start with all the objects in the cone */
visible = sorted.copy
/* parse the objects in the cone, from nearest to the observer to farthest away,
and remove any objects occluded */
for each object in sorted do
/* remove any other object that is occluded by object */
to_remove = []
for each other in visible do
if object.occludes(other) then
to_remove.add(other)
end
end
visible = visible - to_remove
end
return visible
end
