60 second warm-up · How to draw ellipses freehand

Wheels, cups, plates, bottles, eyes and hats are all the same problem. Get ellipses right and a whole category of drawing stops being hard.

Kuyambiranso seshoni

Kodi izi drill magalimoto

Ellipse ndi mchenga wowoneka m'mphepete mwa msewu, ndipo malamulo omwe amatsimikizira kuti mchenga ukuwoneka mozungulira ndi awa: momwe umawoneka mozungulira kumadalira momwe umawoneka m'mphepete mwa msewu. Mchenga wowoneka m'mphepete mwa msewu ndi mzere wozungulira. Mchenga wowoneka m'mphepete mwa msewu ndi mzere wozungulira. Mchenga wowoneka m'mphepete mwa msewu ndi mzere wozungulira. Mchenga wowoneka m'mphepete mwa msewu ndi mzere wozungulira. Mchenga wowoneka m'mphepete mwa msewu ndi mzere wozungulira.

Chilamulo chachiwiri ndi cha makina ogwira ntchito kuposa choyamba. Mtundu wabwino wa elipses umapangidwa mofulumira, mozungulira nthawi zambiri m'njira imodzi yosatha, ndipo kenako mumakhala ndi njira yabwino kwambiri. Ngati mwaipanga mofulumira, imatuluka mozungulira pamodzi nthawi zonse, chifukwa mikono siyingathe kuteteza mzere wolimba pa mtunda wotsika - mfundo yofanana ya physics yomwe imachititsa kuti mizere yoyenda mofulumira iwonongeke.

Muffins, magalimoto, matumba, ma bottles, ma plates, ma hats, ma eyes ndi ma wheels onse amene mudzawapangire ndi vuto limodzi pa kukula kosiyana, choncho nthawi yokhala pano imalipiranso m'magulu onse a nkhani kuposa imodzi.

Momwe mungachitire

  1. Chonde ganizirani za axis yaitali koyamba ndipo muike ngati mzere woyera. Ellipse ndi symmetrical pa axis, ndipo popanda kuika, simudzawona pamene inu simungakhale.
  2. Sankhani momwe amazungulira kuti muyambe - zomwe ndi dera, ndipo zimachokera ku momwe mbali ya mawonekedwe ndi kuchokera ku gawo la maso anu.
  3. Hover ndi kuphunzira loop awiri kapena atatu nthawi pamwamba pa tsamba, kuphunzira ghosting chimodzimodzi liwiro drill amagwiritsidwa ntchito.
  4. Kukhudza pansi ndi kupita round 3 kapena 4 nthawi popanda kuletsa.Sankhani kuti musayambe pakati pa mapasi.
  5. Kupita kwa maola asanu ndi atatu ndi koipa kuposa atatu, chifukwa pa ola lachisanu ndi chitatu mumakhala mukusintha zinthu, osati kujambula.
  6. Ngati imodzi mwazigawozi ndi yolimba, kutalika kwa elipso lonse kumasinthidwa mosasintha - jambulaninso mosasintha kutalika kwa zigawozo.

Kodi zabwino zikuoneka ngati

Ellipse yabwino ndi yofanana ndi ma axis ake awiri, siyimakhala ndi malo ozungulira kapena ma corners, ndipo imapangidwa ndi ma pass awiri kapena atatu ozungulira omwe amatsatira njira yofanana. Ellipse yoipa ili ndi nkhope yozungulira, ma corners owoneka bwino komwe ma arcs awiri amakumana, kapena ma ends omwe satsegulidwa.

Mtundu wa kumanja ndi wa classic slow ellipse: gawo loyenda mozungulira pamwamba, m'mphepete komwe wolembayo adasintha njira, ndi m'mphepete komwe maziko awiri sanakumane.

Zomwe tikuwerengera, ndi zimene mfundoyi ikutanthauza

Kupatulapo, ngati mukufuna kulemba masamba a 100, muyenera kulemba masamba 100.

Smoothness is scored separately as line confidence, so a wobbly ellipse in exactly the right place and a smooth one in the wrong place fail differently and get different advice. That separation is the reason a single overall drawing score would be useless.

Ngati seshoni imapereka maonekedwe otseka osachepera kuti agwirizane, palibe chomwe chimafotokozedwa kwa seshoniyo. Tidzasonyeza kusiyana kuposa idadi yomwe sitikhulupirira.

Momwe mungapangire mug - ma elips awiri omwe ayenera kugwirizana · Momwe mungapangire ice cream cone - mapiri omwe amapanga · Momwe mungapangire maso - iris ndi elips, si m'mizere · Momwe mungapangire apple - sphere yomwe siyimakhala yofanana · Momwe mungapangire ana - mapiri awiri ozungulira pansi pa thupi · Momwe mungapangire nkhope - cranial ndi mpira

Mwachitsanzo, pamene nthawi zambiri zimapita mosayenera

Kujambula kwa slowly. Izi zimapanga malo opanda pake pamodzi ndi mbali imodzi popanda kulephera, ndipo palibe kuchuluka kwa chisamaliro chochotsa - nthawi yokhayo yomwe imachita.

Kumanga izo kuchokera ku four arcs. Four quarter-arcs kugwirizana up amakupatsani awiriawiri, ndi maso apeza aliyense wa iwo.

Kujambula mbali yoonekayo yokha. Pa mkaka kapena tin, jambulani ellipse yonse kuphatikizapo gawo lofiira m'mbali mwa chinthu, kenako sankhani zomwe mungachitire. Kujambula m'mbali mwa mkaka wokha kumakupatsani malire omwe sadzatsegulidwa.

Kusiya kuganizira za dera. Ngati pamwamba pa silinda ndi kozungulira kuposa bokosi lake, chinthucho chikuyenda kumbali yanu, ndipo izi sizoyenera kukhala zomwe munali kuyembekezera.

Mafunso pa elipses

Kodi ndingatani kuti nditenge chigawo choyenera cha freehand?
M'njira yofulumira, m'njira yopanda malire, kuzungulira katatu kapena katatu, ndikuti mupange njira yabwino kwambiri. Mphamvu ndi yankho lonse - m'mphepete mwa msewu wothamanga nthawi zonse ndi wolimba.
N'chifukwa chiyani elipses anga ali ndi masamba ozungulira?
Mudzathamanga m'mphepete mwa mzere, nthawi zambiri m'mbali mwake komwe kuyendetsa kuli kovuta kwambiri. Rotate the paper, or move from the elbow rather than the wrist.
Kodi ndi chiyani chimatanthauza degre ya ellipse?
Kodi round it looks, yomwe imangotengera momwe mbali yake ndi kuchokera pa mlingo wa maso anu. Pa mlingo wa maso mzere wazungulira umawoneka ngati mzere; pansi pa inu imawoneka pafupifupi yozungulira.
Kodi ma elips awiri a pa chikho ayenera kukhala ofanana?
Kutalika kofanana, koma pansi pamodzi ndi nthawi zonse pang'ono rounder, chifukwa ndi mbali ina ya m'maganizo anu. Kupeza kuti m'mbuyo ndi zimene zimachititsa drawn zidutswa kuwoneka ngati iwo akuyenda pansi pa tabu.
Kodi ndi chinyengo kugwiritsa ntchito template ya ellipse?
Ogwira ntchito amagwiritsa ntchito nthawi zonse, choncho palibe - koma template siyidzakulitsa mkono wanu. Musagwiritse ntchito imodzi pantchito yomaliza ngati mukufuna ndipo mupange fumbi laulere pamodzi.
Kodi ndiyenera kujambula anthu angati panthawi imodzimodzi?
12 m’maola asanu ndi awiri ndi nthawi yabwino. Ngati mukuchita pang’ono kuposa zimenezi, ndiye kuti mwamsanga mumawamanga mofulumira kwambiri.

Mphindi

  • 60 second warm-up Kutentha, si seshoni. Ntchito yake ndi yopeza liwiro loyamba loipa la tsiku kuchokera ku njira ina komwe sichingakhale chofunikira - chitani nthawi yomweyo pambuyo pa kalasi.
  • 5 minute session The weniweni chigamulo, ndi default. Long choncho kuti kuchira amayamba kuchitika m'kati chigamulo mosiyana pakati pawo.
