劃魔方與素描透視

Lonely_7X

<>網上有很多魔方教材，教材中一般都有魔方圖，有沒有人留意過，有些教材中的魔方圖片看著很真實，很有立體感，而有些看著就很彆扭？其實這就是素描透視的表現。現在弄點點有關素描透視的一點小知識給大家看看，希望對以後有興趣出教材的朋友有點用 <IMG alt="" src="http://bbs.mf8-china.com/images/smilies/default/loveliness.gif" border=0 smilieid="28"> </P>

占個位置，如果有人喜歡，我再發點東西來給大家看看

沙发，不错，继续！

黑索金

楼主有没有真个魔方的透视图 好想看看

snowchou

楼主帮我做个橡皮图章吧，哈哈哈

wangyuan01

尽可能把知识用在魔方中，是我们推广魔方的动力！

画魔方用几点透视啊

魔鱼儿

楼主强啊,是学什么的啊

ANTY

LZ辛苦了，大家相LZ学习，用自己所学的知识来推广魔方吧

ANTY

刚刚想到一个问题，感到别扭似乎也就像楼主这种搞美术的人才会觉得吧，太强调现实的立体感会增大普通人绘制魔方的难度，特别是魔方的JAVA，虽然我不是太了解，但要弄到近大远小的效果应该是非常麻烦的吧。图示只是为了方便表达，只要意思清楚了，其实也不需要要求那么严格。
