素描是一切绘画的基础,这是研究绘画艺术所必须经过的一个阶段。狭义上专指用于学习美术技巧、探索造型规律、培养专业习惯的绘画训练过程。

如何选择工具

素描是一种正式的艺术创作,以单色线条来表现直观世界中的事物,不同的笔触营造出不同的线条及横切关系和节奏、主动与被动的周围环境、平面、体积、色调、及质感。不同的作品则需要不同的工具语言来表述,才能更加体现画面的效果,作品才能成功。

干笔适宜作清晰的线条,水笔宜于表现平面;精美的笔触可用毛笔挥洒,而广阔的田野则可用铅笔或粉笔去勾勒。炭笔是两者都可兼用的。对工具的理解是完成好一幅作品的首要条件。

铅笔

美术铅笔的铅芯有不同等级的软硬区别,硬的以"H"为代表,如:1H、2H、3H、4H等,前边数字越大,硬度越强,即色度越淡;软的以"B"为代表,如:1B、2B、3B、4B、5B、6B等,数字越大软度越强,色度越黑;学生用铅笔一般是HB形,软硬适中。对于初学绘画的可从HB到4B中选择三种类型就可以了。

炭笔

炭笔的用法和铅笔相似,炭笔的色泽深黑,有较强的表现能力,是画素描的理想工具,用于画人物肖像尤佳,但画重了很难擦掉。

木炭条

木炭条是用树枝烧制而成,色泽较黑,质地松散,附着力较差,画完成后需喷固定液,否则极易掉色破坏效果。

炭精棒

炭精棒常见的有黑色和赭石色两种,质地较木炭条硬,附着力较强,可用可不用固定液。

画素描通常在专用的素描纸上进行,选用素描纸时要注意纸质坚实、平整、耐磨、纹理细腻、不毛不皱、易于修改,如素描纸、铅画纸。太粗、太薄、太光滑的纸都不适合铅笔画素描。初学者使用的纸张大小以8开或4开为宜,16开大小的铜版纸和复印纸,则适合用钢笔、圆珠笔画素描。

素描纸的表面有明显的纹理,这样铅笔上色才会比较容易,另外,背面的纹理也不一样,背面的纹理要比正面纹理弱,所以应该在纸张的正面绘画。

辅助工具

画架

用来放置素描纸的架子。

画夹

宽边的大铁夹可用在画板上固定纸张。

胶带

胶带也是不错的固定纸张的工具,因为胶带宽度均匀,画完后将胶带去除会留下一条好看的白边

宽笔刷

用起来超级方便的清扫工具,画面上的橡皮屑较多的时候,用它清除就不会弄花画了。

铅笔延长器

铅笔用短了之后都会很苦恼,用的时候不方便,扔了又觉得可惜。将笔的一头放入延长器中,画笔瞬间就变长了。是非常不错的节省工具。

绘画常识

想要学素描,必须要了解一些知识,具体的如下几个方面:

一点透视

最常用到的就是一点透视,因为一点透视只有一个消失点(灭点)所以也叫:平行透视。

凡大小相等的物体愈远,其形愈小,以至于最后消失于一点,这点称为消失点。根据消失点的不同位置,能观察到的面也不同。当消失点在物体外侧时,可看到2个面,在物体上方时能看到3个面,在物体内侧时只能看到一个,如果物体正面是空的,则看到的是物体的内部结构。

不论画什么物体都可以归纳、概括在一个立方体或者多个立方体中,只要有一个面是与画面平行的,就可以利用一点透视(平行透视)来作画。一点透视合适画小的物体,透视变化不大,但是画的时候一定要体现出来。

站在宽广的平地上向前看,远方天地的交界线,称为地平线,地平线是处理透视图形的重要依据。平视时地平线和视平线重合,地平线就是视平线;俯视时,地平线在视平线的上方。

位置在画者右方的景物,看见它的左侧。位置在画者左方的景物,看见它的右侧。

凡在视平线以上的景物,愈远在画纸上的位置愈低。视平线以下的景物,愈远在画纸上的位置愈高。

有了以上这些绘画透视知识如果掌握并且运用到绘画中就不会在画中犯常识性的错误,而且构图会合理,符合视觉欣赏的美感。

两点透视

物体有一组垂直线与画面平行,其他两组线均与画面成一定角度,而每组有一个消失点,共有两个消失点,称为两点透视。

两点透视(成交透视)

两点透视图画面效果比较自由、活泼,能比较真实地反映空间,可以反映建筑物的正侧两面,容易表现出体积感。另外,两点透视加上较强的明暗对比,物体体感会更强。

认识明暗

明暗产生的原因:有光源(不论是自然光源、人工光源)照射,才会产生明暗;光源直射处(向光)是明亮部,照射不到之处(背光)是黑暗部,反射光所形成的是中间灰色部分。没有光,我们的眼睛将看不到任何东西。

利用铅笔表现明暗的方法:

铅笔直立地以尖端来画时,画出来的线较明了而坚实;铅笔斜侧起来以尖端的腹部来画时,笔触及线条都比较模糊而柔弱,笔触的方向要整理才不致混乱。

铅笔画使用橡皮擦注意事项:

初学画一笔不满意时,就马上用橡皮擦去了,第二次画得不对时又再擦去,这是最不好的习惯。一则容易伤害画纸使纸张留下疤痕,再则画时就越画越无把握了,所以应极力避免。

当第一笔画不对时,尽可再画上第二笔,如此画时就有一个标准,容易改正,等浓淡明暗一切都画好之后,再把不用之处的铅笔线,用橡皮轻轻擦去,这样整幅画面就清楚可爱多了。

画面上的线痕通常到最后都会被暗的部份遮没了,把露出的部份擦去较为省力。同时不用的线痕,往往无形中成为主体的衬托物,所以不擦去无害于画面,有时反而收到无形的效果,这是我们不可不注意的地方。

空间感

在绘画中依照几何透视和空间透视的原理,描绘出物体之间的远近、层次、穿插等关系,使之在平面的绘画上传达出有深度的立体的空间感觉。

前面的物体不要画到后面去了也不要把后面的物体画到前面了,合理的安排他们的位置。让整个画面有一个前大后小,前实后虚。上实下虛的空间效果。总之就是画面的层次感明确。

入门

画素描之前要充分做好各种线条的练习,还要做线条的由浅入深、由深到浅的成组练习。经过构图、轮廓、大形深入刻画到整体调整等不同的作画环节,这个作画的过程体现从整体到局部到整体的观察过程。如果没有这种正确的作画程序,就不能保证画面的准确、深入与完整。

素描步骤

画前要观察研究物体的基本形状,看它的受光方向,结构造型,形成的立体效果,然后用直线勾出它的大体轮廓,再依照光源,确定物体的受光(淡面)、侧光(灰面)、遮光(深面)三大部分。最后在这些面与面之间加上衔接的层次,使它自然、圆润起来,直到表现出质感为止。 素描画好后要对描绘的物体进行统筹和完善加工。

https://www.bilibili.com/video/BV1mE41167Vm/?p=1&vd_source=6b26da26630111503906a454dabeb61d这个视频讲的是受光的技巧,比较浅显易懂,有助于进一步理解。

构图

构图是每一个学习绘画的人所必须要掌握的一项基本能力,从美得感受出发,让观赏者感受到美、舒服。各部份的一种配置法,依照经过设计的格式,一致的比例,或重复的体系去安排。一般情况下在绘画中构图讲究天小地大、左右均衡;各物体大小适中,整体完整,不可过小,亦不可过大。

五种方法

1、三角形构图,素描静物中最常用到的。

三角形构图是最常见的和最稳定的构图形式,静物分成三组放在三个顶点上。此类构图画面稳定、主体突出、层次明确、错落有致,适合静物数量较少的组合。

三角形的三条边是由不同方向的直线合拢而成,而不同的线条组成不同形式的三角形,产生不同的趋势和变化。如果你坐在静物正面中间位置,可能会更多采用三角形构图。

2、C形构图

“C”形构图,画面动感程度优于其他形式的构图。

这种构图方式使画面具有流动性,更容易表现较大空问的静物组合。“C”形有三个点,主体物往往在中间点的位置.前面的点往往是第一次要物体的摆放位置,最后面的点帮助你加强画而空间层次的推移。

3、S形构图

"S”具有曲线的优点,优美而富有活力和韵味,所以“S“形构图给人一种美的享受,而且画面显得生动、活泼。读者的视线随着"S”形向纵深移动,可有力地表现其场景的空间感和深度感。在 "S”形构图中,通常会缩短 "S”的上部,拉长 "S”的下部,以形成“上紧下松”的构图关系。

4、圆形构图

圆形构图就是让静物在画面中围成一个圆圈。圆形构图在视觉上给人以旋转、运动和收缩的审美效果。

当圆形被拉长时,就会变成椭圆形。椭圆形构图大都采用宽大于高的横幅形式,它不仅有静态效果,也会产生动态效果,同时还具有较为明显的整体感。

5、水平式构图

水平式构图的物体不能放在画面正中,应当处于一个偏上或者偏下的位置。水平式构图纵向上的空间层次较少,为了让画面丰富,各个物体要在形状、大小、高矮颜色等因素上形成对比,使画面安定、平和,可以增强画面的稳定感。同时还要安排好位置,形成前后的空间层次。

轮廓

素描轮廓线是指物体外部和内部形状对线条,描述前进或后退的形状之变化方面的一条断续线或连续线。也指物体对形,没有轮廓线就没有"形” 。

一般来说轮廓包括外轮廓和内轮廓,两者相互依存,就是说外轮廓画错了,内轮廓也必然跟着错,内轮廓错了也会影响外轮廓的准确。在实践中存在的问题是容易把二者分开来观察,分开来画,分开来检查,必须两者结合起来观察并结合起来画才对。要知道轮廓绝非指简单的物体的外框,要内外兼顾方可画准。

轮廓就是形状,画画的第一步是画形状。形状图对了,就顺利了。越画越难受。勾勒轮廓的暗部可以简单处理,勾勒轮廓的同时可以详细画明面。由于形状的透视变化,尤其是轮廓,一分钟宽度等于几英寸宽度,因为边缘是立体形状。当一个同样宽度的面转向后方时,面的长度会越来越窄,直至消失。

如果外轮廓和内轮廓的基本比例和位置不正确,包含所有细节的形状也会是错误的。所以大纲的确定要严格、严格、细致。 严谨谨慎不是要求你谨小慎微,而是要求你胆大心细。只有大胆细致的书写,勾勒出轮廓,才能知道这幅画的对错。我们要敢于肯定,也要敢于否定和纠正错误。

要想画出正确的轮廓,必须对物体的形象有正确的认识和观察。观察轮廓也是专业训练不可缺少的阶段。一种不仔细观察研究对象,就无法在反复修正的过程中提高识别能力,也无法培养敏锐的视力,理解简单形式的复杂性。

排线

排线是素描最基本的语言元素,在素描中丰富的色调变化是经过许多次的线条叠加而形成的,这其中线条的走向与角度尤其需要注意。画好素描排线就要有一个正确的握笔姿势。

正确的握笔姿势,可以分为两种:持棒式和握笔式

持棒式:

用拇指、食指和中指,三指拿笔与手掌下,如上图,中指起到辅助作用。用拇指左右摆动,在画面形成规则的接近平行的一排线。在用持棒式方法的时候,笔和画面大约在35度角左右就差不多,手和手腕不要接触画面,如果难掌握,可以用小指做支撑点,也可以用手腕自然的上下画出线条。

握笔式:

这种方法就是平时的写字姿势,如上图,这种的握笔方法可以用在面积小的暗面,或者在单体塑造的时候,这种方法用的很多,不像持棒式是在面积大,握笔式很容易掌握,就像写字一样画线条。

若干组排线最好不要沿同一方向展开,因为沿同一方向或缺乏方向变化的十字形(夹直角)都将导致画面出现板滞和类似平涂的光赋效果。

用一组组的线排开,颜色深浅不同,表现出明暗关系。当我们画苹果时,在背光处铺出一组调子,就是画的暗面。

线只是用来表现明暗变化,以此来塑造物体体积,表现空间的一种手段。无论怎么排线,只要画出效果就可以,不拘泥于各种形式。各种线的画法会产生不同的效果,所以在画不同的画时我们可以用不同的排线方法。

苹果的画法视频已经讲了很多,感兴趣可以看看https://www.bilibili.com/video/BV1ct411Q7RE/?spm_id_from=333.337.search-card.all.click&vd_source=6b26da26630111503906a454dabeb61d

控制明暗的逐渐变化以创造实体形式的错觉效果,使物体有三度空间的特质。在深面与灰面上先铺上一片均匀的线条,使受光面暂时空出,这样就是用大块大面来表现物体,然后将各个块面中细部,也同样依照受光、侧光、遮光分成小块、小面来处理。还要注意小块、小面的明暗,使它们服从大面的统一调子,而大面又必须服从于整体。https://www.bilibili.com/video/BV1Zh41147Dk/?spm_id_from=333.337.search-card.all.click&vd_source=6b26da26630111503906a454dabeb61d这个视频讲的是五种线条的画法,实践与理论相结合。

深度学习

速写

速写一般不拘泥于局部的形似,而常以形写神,表达方式简练,对专业创作、设计草图和快速表现都有积极的意义。速写的高度提炼与时间较长、较深入地练习是相辅相成互相促进的,速写画得多,在复杂的素描写生开始阶段也会更快地把握构图和造型。

以素描作画相对的时间为依据,短至数分钟长则半小时左右都可算是速写,因速写的基本特征是简练而快速地写生,因此是画者的第一印象。

对结构理解的深入扎实的素描基本功,在速写中也会体现出来。经常大量的速写训练,可以最有效地培养敏锐的观察力和艺术的概括能力,以及提高快速高效的表现技能。

速写是一种非常便捷的素描方式,其常见题材有风景速写、人物速写、动物速写等。

构图

构图的重要性,大家都知道,单个动作的构图比较简单,原则上宁上勿下。动作朝左,构图偏右即可。双人组合要注意两个动作的主次对比和相互谐调,首先比例要一致,站立的动作和坐着的动作一样高是不行的。场景组合难度较大,透视是最需要注意的,前大后小的原理一定牢记。

人物

人体躯干在衣服的包裹下,无论是厚衣服还是薄衣服,都是紧贴人体的躯干形体。

从衣领开始描绘,形体外轮廓与运动所产生的褶皱相结合刻画。注意海条线条的粗细、深浅、长短变化。

紧接上一步,调整画面的素描关系,可以上一些调子来拉开画面的关系,注意调子的轻重。

注意构图,比例,动态块的侧锋勾画出对象的大体形块。起形要概括,快速,不要在意那么多细节。

可以先把头部深入出来,然后再推出全身。但是要注意五官要画得精致准确,做到一气呵成,不然容易影响后面。

较常用的步骤:五官虚带,定出位置和大小,快速把整个人物画出,抓住大的框架形状和此较明显的穿插关系。先深入五官,手脚与其他最后深入。优点:即使画面随时停下也可以保持画面完整。不会有没有画完的感觉。难点:要整体观察把握,对于穿插比较理解。

坐姿一般选在正侧和四分之三角度比较容易表现,要注意人物的整体动态走势与整个人的比例关系,不要把上短和把腿画的过长。

快速勾出整个人的框架形(如头、胸腔、胯部、四肢,手脚)要肯定整体,可以略带穿插关系,不需要画多。时刻整体地去观察,不能陷入局部。

完善细节:画出头手脚具体形象,并增加灰层次,同时调整衣纹关系,加入裁剪线等装饰。

深入画面:用侧锋带出灰面,增加胸腔,盆腔,四肢的体积感。调整画面主次关系,注意前后胳膊,腿的强弱关系。

默写

默写是脱离了写生对象,完全凭着自己的记忆和理解来把握画面的,在素描的学习中适当地配合默写训练,有助于增强视觉形象的记忆能力,同时又可以训练对画面图形的创造性思维和表现能力,有利于加深写生中对素描知识的理解。其实默写和速写也有着密切的关系,在速写中不可能看一眼画一笔,很多是靠对写生对象的理解和记忆来完成的。

掌握头部解剖

在没有模特或具体的作画对象时,画者只能通过记忆或平时头像写生的经验来完成对头像的默写。内外部形体结构的把握能力,以及对素描技法的合理运用和表现能力。在平时的训练中要着重理解头部骨骼的构造、熟悉头骨各部位的名称及正确位置,做到没有参照对象也熊熟练正确地画出头部各部位的位實及解剖关系。

头像写生训练

平时要积累大量的人物头像写生的作画经验,在人物头像写生训练中,要有针对性地选择写生对象。如选择考试中经常出现的男青年或女青年模特进行写生训练,也适当选择一些老年模特写生,有备无患。

临摹加强记忆

临摹是学习头像写生的最好办法,也是提高素描头像造型能力的有效途径之一。通过临摹,学习他人的经验和技法,真切地体会画者的感受和意图,领会作品的精神所在。这样既节省时间又事半功倍。临摹还能提高眼睛的准确观察力及眼与手的配合能力。

静物作画技巧

素描所表达的是形体与空间不外乎黑、白、灰三字,一幅素描起码应该具备三个方面的成功:一是形体结构准确,二是黑、白、灰大层次分明,三是中心焦点突出。

中心焦点是有视觉习惯形成的,所谓焦点,在客观上应该是在结构中最有特征、又最能展示形体与空间部位的。常位于画幅前景接近中心的部位,是中心也是重心。画素描就应有点偏心,如果平均用力不仅破坏了整体感,也违背了视觉的真实。

轮廓线(包括一些局部轮廓线)只是物体的某些面在转移时被缩小了形象,用轮廓线来认识世界不应是初习素描者的课题,而先要学习用立体的观念来研究世界。

这条线的表现力是不容忽视的,因为物体表面有丰富的起伏向纵深转折时又与空间组成各种关系,它时浓时淡,宽窄虚实,变化无穷,不单单只是一条“线”。

第一是结构,第二才是光,黑白则是它的附属物。大家要学会借助黑白来认识形体结构,但有时黑白也会歪曲形体结构的原来面貌。

画素描就是找区别,大区别就是“大关系”,凡是大关系都具有整体性的分量,它容纳并制约着所有局部,因而它是最重要的。小区别就是“小关系”,就是指处于同一色调中的轻微差异。相对于整体来说,它们只能被称之为“局部”。它们以一定的比例或层次关系组织起来并充实着整体。

没有局部,“整体”便是空的,而如果没有整体的制约,“局部”就成为散乱无序,所以它们是相辅相成辨证统一的。

结构的透视变形色调的黑白相称,对边线的虚实处理,三者共同担负着表现空间与体积的任务。

线和线条技法

素描的要素是线,但是线在实质上却是不存在的,它只代表物体、颜色和平面的边界,用来作为物体的幻觉表现。直到近代,线才被人们认为是形式的自发要素,并且独立于被描绘的物体之外。用线条来组成物体的形象,并且描绘于平面之上,藉由线条形式引起观者的联想。

例如两条线相交所构成的角形,可以被认为是某平面的边界;另外加上第三条线可以在画面上造成立体感。弧形的线条可以象征拱顶,交会聚集的线条可表现深度。人们可以从线条的变化当中,得到可以领会的形象。

用线条区分立体与平面,至于色彩明暗是为了加强和厘清整体与部分的关系。运用线条的开始,消失和中断来画出边界,并且形成平面,也可使色彩至边界而上。

线条的粗细能表现物体的变化,甚至光和影也可用线条的笔触变化表现出来,还需要平面技法的辅助。平面技法在使用炭粉笔时,在明暗对照上可用擦笔法。素描也可用多色画笔作为基本材料,用来加强素描效果以及素描的艺术性。

素描的线条技法还需要平面技法的辅助。平面技法在使用炭粉笔时,在明暗对照上可用擦笔法。

毛笔画法的使用

更重要的是使用毛笔画法,因为毛笔能发挥笔触的宽度和笔调的强度并且能增加空间感和立体感。

艺术性的加强

素描也可用多色画笔作为基本材料,用来加强素描效果以及素描的艺术性。

明暗

明暗交界线是素描中灰面与暗面的交界,虽然名字是明暗交界“线”,但是它是由“面”组成的,由于光线以及静物本身形体的变化,明暗交界线也会有非常丰富的变化。

有一些静物因为形体会有很多明暗交界线,所以我们找到这些明暗交界线之后统一暗部,然后这些明暗交界线的色调也要做一个区分,靠近光源的颜色稍微要亮一些。

结合视频讲解可以明白明暗的运用手法https://www.bilibili.com/video/BV14m4y1978u/?spm_id_from=333.337.search-card.all.click&vd_source=6b26da26630111503906a454dabeb61d

3. nts342r6a全站仪说明书

1、得到本地的蓝牙适配器并且打开蓝牙,得到本地蓝牙适配器;

2、扫描周围的设备,通过BluetoothAdapter 的startDiscovery进行扫描,找到一个设备,就会发出一条广播,所以找到的新设备要在广播接收器里面进行接收;

3、通过广播接收器找到扫描到的新设备,得到BluetoothSocket;

4、通过BluetoothSocket 对象读写数据,收到数据后,通过Handler 发送message来刷新界面;

5、拿到BluetoothSocket之后,就可以进行通讯了,通讯的代码和作为客户端连接设备应该是一样的

4. nts-332r6全站仪怎么操作

1、开机后先按S.O键,输入文件名(可选项)。

2、确定,再按S.O键下翻。

3、F2键选择新点,再按F2选择后方交会法,再选择一个文件,确定,自定义点名(可选项)。

4、F1距离后方交会,输入仪高,确定,在NO1#界面里面选择坐标,输入第一个已知点的坐标,在已知点上架好棱镜,测量,再用同样的方法进行第二个点的操作。然后再看残差(观测值与预测值之间的差)大不大,不大就可以进行计算,接着就是进行定位放线了。

5、放样

放样—新点—后方交会法—输入点名—回车—输入仪高—回车—输入A点已知坐标—输入棱镜高—测量距离—自动保存—输入B点坐标—输入棱镜高—测量距离—自动保存—计算—记录—最后完成。

全站仪后方交会注意事项:

1、全站仪后方交会法跟极坐标法的原理是一样的,都要有两个已知条件。

2、极坐标法有两个已知坐标或者一个坐标一个方向就可以了,后方交汇要有两个坐标。

3、在仪器里面找到后方交汇,有的叫交会测量,有的叫新点。每个仪器不同都不一样。

4、有的一起要输入两个坐标后在测距,有的是输一个测一个。输入坐标,然后测距,然后按计算,定向就可以了,后交有条件限制的。

5、根据经验交会角度不能小于15度和大于165度、更不能再一条直线上或者三角关系危险圆上。要不然仪器就不能计算出结果,无法交会。

6、对交会距离也有一定限制,得慢慢摸索,总之比极坐标法好用,可以交会2个坐标,也可以交会很多坐标,坐标多精度高。

答:操作上都是大同小异的。型号就多着了,主要分进口与国产的,进口的有徕卡、拓普康、索佳、天宝、宾得、尼康等等;国产的就是北京博飞、南方(其实南方公司又有南方、瑞得、三鼎、科力达四个品牌)、苏一光、常州大地、科维、中纬等等。每个厂家旗下又有各系列的全站仪,要一一比对也不是马上能比对得完的。

从功能应用上,也主要是使用放样,与坐标测量的功能。或者道路软件的应用,平纵横面的测量计算等等。

全站仪,即全站型电子测距仪(Electronic Total Station),是一种集光、机、电为一体的高技术测量仪器,是集水平角、垂直角、距离(斜距、平距)、高差测量功能于一体的测绘仪器系统。因其一次安置仪器就可完成该测站上全部测量工作,所以称之为全站仪。广泛用于地上大型建筑和地下隧道施工等精密工程测量或变形监测领域。

南方全站仪目前主要的型号有 NTS-391R10、NTS-382R10、NTS-372R10、NTS-382R6、NTS-362R6、NTS-362R4、NTS-391R、NTS-82、NTS-342R5A、NTS-341R10A、NTS-342G、NTS-342R10A、NTS-330、NTS-310、NTS-341I、NTS-332R10M、NTS-362R。
