There are a great deal of paintings attributed all or in part to Leonardo da Vinci. In fact, there are only a relatively few known works of his. Among the many paintings attributed to Leonardo da Vinci are some that are collaborations where other artists are responsible for much of the work and design, and there are many that Leonardo had no hand in creating. We recognize that different sources produce different information so
we are providing a list of acceptable paintings to be recreated for score in D6. Please select on of the paintings by LDV from this list.

古典…莱昂纳多的工作室

适合I, II, III 组和IV组

1.　2018年10月3日

B8c–LDV绘画的再创造：用来创建LDV绘画相似性的非常规介质可能产生不平坦的、纹理化的表面。然而，在演出过程中，无论朝向何方，对官员和观众来说，娱乐活动都必须是二维的。

2.　2018年10月30日

B6——LDV角色：必须被描绘成真实的历史人物，达·芬奇。人物的外貌意在看起来像实际的历史人物达·芬奇。

3.　2018年10月30日

B8c——一个LDV绘画的再现：有大量的绘画被全部或部分地归于达·芬奇。事实上，他的作品中只有很少一部分是已知的。在许多属于达芬奇的绘画作品中，有一些是其他艺术家合作完成的，其中许多是达芬奇没有参与创作的。我们认识到，不同的来源产生不同的信息，所以我们提供一个可接受的绘画名单，以重新创建得分在D6。请从这个列表中选择LDV的绘画作品。

4.　2018年10月30日

B8d&e-LDV作品：这些不局限于绘画的列表。他们可能是任何设计，绘图，草图等归因于LDV。请提供您的选择文件，并提交您的名单。这将有助于保持比赛时间表，并验证您的选择作为LDV工作。

The correct cost limit for this problem is $145 (U.S.), not $125.

2
October 30, 2018
F2 – Supported by one or more fans:
In this context, “fans” means enthusiastic spectators not participating in the game, not mechanical devices for moving air. Thus, one or more characters will be observably supporting a contestant.

3
October 30, 2018
C2 – Score Cross Bar and taped boundaries & Figure C:
The boundary lines are only a visual reference to help judges determine whether or not a structure has crossed over the Score Cross Bar entirely or partially between its endpoints. Structures are not required to land within the boundary lines but must cross above some point of the Score Cross Bar. For example, if a solid wall was placed directly above the Score Cross Bar the structure would have to impact it to be a successful toss.

October 30, 2018
F1 – Trash item:
The type of trash item must be something that is commonly discarded in its current form but is not allowed to be perishable (garbage). The trash item is a single item but the team is allowed to have many of the same items. The copies may vary in proportion but must be the same in construction and appearance.

投掷结构

适合I, II, III 组和IV组

1. 2018年10月22日

成本限制：这个问题的正确成本限制是145美元（美国），而不是125美元。

2. 2018年10月30日

F2-由一个或多个粉丝支持：在这个上下文中，“粉丝”是指没有参与游戏的热情的观众，而不是用于移动空气的机械装置。因此，一个或多个角色将明显地支持一个参赛者。

3. 2018年10月30日，

C2——记分横杆和带状边界和图C：边界线只是一个视觉参考，以帮助判断一个结构是否已经完全或部分跨越了记分横杆的端点之间。结构不需要在边界线内着陆，但必须越过分数横杆的某个点。例如，如果将实心墙直接放置在分数横杆上方，则结构必须对其产生影响，才能成功抛掷。

4. 2018年10月30日

F1-废弃物品：废弃物品的类型必须是通常以当前形式丢弃但不允许易腐烂的东西（垃圾）。废弃项目是单个项目，但允许团队有许多相同的项目。复制件可以按比例变化，但在结构和外观上必须相同。
