視覺算法

Question

的突擊隊式線能否請你點我的視線渲染算法的線的文章？我正在尋找類似於Commandos系列遊戲中使用的類似遊戲（由Pyro Studios製作）。視線圓錐/三角形必須呈現（在自上而下的視圖中）並帶有由障礙物引起的適當陰影。 感謝

在僞代碼：

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
