섹션 I Rhino로 주얼리 디자인 렌더링 만들기
1. Rhino 3D 배우기
전문 산업 디자인 소프트웨어인 Rhino는 현재 가구, 전자, 자동차, 항공우주, 주얼리 등 다양한 산업 분야에서 널리 사용되고 있습니다. 모든 분야의 디자이너가 반드시 익혀야 하는 소프트웨어 기술이 되었습니다. 배우기 쉽고 조작이 편리하며, 그 원리는 가장 널리 사용되는 정밀한 NURBS 서피스 원리를 기반으로 합니다.
NURBS는 국제적으로 인정받는 산업 등급의 정밀 설계 표준입니다. 폴리곤 메시 모델과의 차이점은 NURBS 서페이스는 모양을 제약하는 과도한 메시 와이어프레임 없이 곡률과 곡선 정밀도에 따라 모델을 구성할 수 있다는 것입니다. 따라서 부동 소수점 연산 횟수를 절약할 수 있으며 최소한의 NURBS 커브 조합으로도 충분히 정확한 서페이스를 얻을 수 있습니다. NURBS 표면은 렌더링 중에 매우 높은 렌더링 해상도로 설정할 수 있으며, 이는 메시와는 다릅니다.

Rhino의 사용자 인터페이스
Rhino의 인터페이스는 3D Studio MAX, AutoCAD, Maya, Softimage와 같은 다른 3D 소프트웨어와 유사합니다. 아래 표와 같이 크게 다섯 가지 영역으로 나뉘며, 각 영역은 용도에 맞게 사용됩니다:
Rhino의 인터페이스 영역
| 인터페이스 영역 | 지침 |
|---|---|
| 메뉴 | 명령, 옵션 및 도움말 파일로 작업하기 |
| 도구 모음 | 명령 및 옵션 사용 단축키 |
| 조회수 | 도면에서 3D 모델과 2D 곡선을 다양한 보기로 표시하기 |
| 명령줄 | 실행된 명령 및 해당 정보 목록 |
| 상태 표시줄 | 입력 포인트의 좌표, 개체 상태, 토글 선택 항목 표시하기 |
Rhino의 운영 인터페이스
(1) 메뉴
메뉴는 인터페이스의 맨 위 레이어에 있으며, Rhino의 대부분의 명령은 드롭다운 메뉴로 배열되어 있습니다. 명령을 실행하려면 명령 항목을 직접 클릭합니다. 작업은 다음과 같습니다:
Rhino 메뉴
(2) 도구 모음
Rhino의 도구 팔레트에는 명령을 빠르게 실행할 수 있는 단추가 있습니다. 부동형 도구 팔레트를 뷰의 아무 곳에나 배치하거나 드로잉 영역의 가장자리에 도킹할 수 있습니다.
Rhino가 시작되면 드로잉 영역의 상단에 일반 도구모음(저장과 보기 제어 버튼 등)이 포함되고, 드로잉 영역의 왼쪽에 편집 도구모음(선택과 복사 버튼 등)이 포함될 것입니다.
도구 설명의 역할은 각 도구의 이름과 기능을 표시하는 것입니다. 커서를 움직이지 않고 도구 버튼 위로 이동하면, 명령의 이름이 표시된 노란색 도구 설명이 나타납니다. Rhino에는 두 개의 명령을 실행할 수 있는 도구 단추가 많이 있으며, 도구 설명에는 두 명령의 바로 가기 키와 명령 이름이 표시됩니다.
드롭다운 도구 버튼이 있는 많은 도구가 도구 모음에 팝업으로 표시될 수 있습니다. 팝업 도구 모음의 도구는 일반적으로 같은 유형의 도구에 속하며 마우스를 클릭하면 버튼이 자동으로 접힙니다.
팝업 도구 버튼의 오른쪽 하단에 흰색 삼각형이 있습니다. 도구 모음을 팝업하려면 마우스 왼쪽 버튼으로 버튼을 길게 누릅니다.
프롬프트 상자
팝업 도구 버튼 및 팝업 도구 모음
(3) 보기
보기는 조작 중인 객체의 투영과 원근을 표시하는 영역입니다. 기본 설정은 상단, 전면, 오른쪽 및 원근으로 구분된 4개의 보기입니다. 보기 제목 표시줄 또는 가장자리를 드래그하여 보기 크기를 이동하거나 변경할 수 있습니다. 각 뷰에는 고유한 기본 평면과 투영 방법이 있습니다. 새 보기를 만들고 이름을 변경하거나 보기의 옵션을 재정의할 수 있습니다.
보기 제목 열을 마우스 왼쪽 버튼으로 두 번 클릭하여 작은 보기를 큰 보기로 전환하여 전체 그리기 영역을 채웁니다.
작은 보기를 큰 보기로 전환
(4) 명령줄
명령줄은 명령을 입력하거나 실행된 명령의 이름을 표시하는 영역입니다. 보기 영역의 위 또는 아래에 배치할 수 있습니다. 시스템의 기본 명령줄에는 세 줄의 명령이 표시될 수 있습니다.
명령줄
(5) 상태 표시줄
상태 표시줄은 인터페이스 하단에 표시되며, 입력 포인트 좌표, 개체의 상태, 토글 옵션 등을 표시하는 기능을 합니다. 상태 표시줄에는 현재 작업 범위로 스냅할 수 있는 강력한 기능도 있어 개체를 정확하게 설정하는 데 매우 유용합니다.
2. 플라밍고 배우기
Rhino 3D의 렌더링 시스템은 매우 제한적입니다. 3ds Max나 Maya와 같은 다른 3D 소프트웨어와 비교하면, 렌더링은 Rhino 3D에서 가장 취약한 부분입니다. 하지만, Rhino의 렌더링 문제를 걱정할 필요는 없습니다. 공식 Rhino 2.0이 출시되었을 때, AccuRender에서 출시한 렌더링 플러그인 Flamingo가 Rhino의 렌더링 기능을 보완하여 Rhino의 렌더링 시스템이 크게 향상되었고, 렌더링 품질도 놀라울 정도로 향상되었기 때문입니다.
Flamingo의 렌더링 시스템은 일반적으로 플러그인이라고 부르는 임베디드 모듈입니다. Flamingo는 Rhino 플랫폼에 임베드된 경우에만 사용할 수 있으므로 먼저 설치해야 합니다. 제가 여기서 사용하는 버전은 Flamingo 1.0이며, 왼쪽 이미지는 Flamingo의 주요 명령 아이콘을 보여줍니다.
Flamingo 렌더링 설정 시스템으로 들어갑니다. 렌더링 메뉴에서 속성 명령을 선택하여 문서 속성 패널을 열고, 문서 속성 메인 패널에서 플라밍고 옵션을 선택하여 각 렌더링 매개변수를 소개합니다.

(2) Misc Options
Use lights——provides built-in lighting in the system; check to turn it on.
Global Plant——global settings provide lighting for various climates.
(3) Ambient Light options
색상—-the color of light. By default, the system is set to black. Readers can adjust the corresponding color, and when the color changes, the rendering result will change according to the color of the light, as shown in below image.
Intensity—-the density of light. In simple terms, it refers to the strength of light. The system provides numerical changes; the larger the value, the stronger the color of the light. When the color of the light is black, it represents no light, and there is no change in the color and density of the light.
Color - The color of light
Intensity——The density of light
(4) Bounces Options
Reflection—- Reflection options. You can set the number of light reflections; the greater the refraction value of the light, the more times the light bounces within the object, which is most evident on transparent materials.
Transparency—-the number of light bounces. The higher the bounce value, the richer the colors and layers in the image, which is most evident on transparent materials. The bounce value is related to the reflection and refraction values, and the system provides manual adjustment for free control.
Bounces options
(5) Anti-aliasing Options
Low — Low anti-aliasing: Visible jagged edges in the image.
Medium — Medium anti-aliasing: Jagged edges are less noticeable.
High (4x) — High anti-aliasing (4x): Smoother edges (recommended for test rendering).
High (6x) — High anti-aliasing (6x): Smooth edges.
High (8x) — High anti-aliasing (8x): Very smooth edges (recommended for final rendering).
Antialiasing options
(6) Special Effects (Special Tools) Options:
Soft shadows: When unchecked, the shadows are hard, indicating direct lighting; when checked, the shadows are soft, indicating indirect lighting, enhancing the sense of weightlessness in the image, simulating the real shadows of objects in real life; when checked, rendering time is extended, do not enable during test rendering, please select according to requirements during final rendering.
No blurry transparent – When checked, no transparent blur is produced.
No blurry reflection – When checked, no transparent reflection is produced.
Depth of field – Depth of field option. Used to simulate the effect of reality between focus and blur. When checked, the rendering time increases geometrically; do not enable it during test rendering; please select according to requirements during final rendering.
Focal (camera focal length) – The value can be changed according to needs.
Fuzz (quality of blur) – The value can be changed according to needs.

4. Rendering Jewelry Design Effects Using the Rhino Platform in Conjunction with Flamingo and TechGems
This chapter will provide a detailed step-by-step example to help readers understand how to create jewelry renderings using the Rhino platform with the Flamingo renderer and the TechGems plugin.
Open the Rhino system and open the RIO.3dm file to see the combined model of the ring. The design and modeling process is not described in this chapter, so let’s enter the world of rendering together.
Select the menu Render > Render command (or click the icon) in the floating tool panel) to pop up the rendering window. Without assigning any material to the object, the Rhino system provides a default plaster material, which, although the image quality is generally low, renders very quickly.
Object view
4.1 Endowing Objects with Metallic Texture
First, select one of the ring surfaces in the previous page’s image, then choose the command Edit > Object Properties from the menu (or click the icon in the floating tool panel to bring up the Properties dialog box).
Click the Browse button in the Plug-in section to enter the Material Library dialog box.
Expand the materials in the material library (You must install the TechGems plug-in before this material can appear. Select the Metals material category and continue to select Gold, Red Polished metal material; the material image style will appear on the right; click OK to confirm and close the dialog box.
Enter Material Library
Choose other ring surfaces and apply different metal materials similarly, giving the gemstones the corresponding materials.
After material allocation, testing rendering can be performed. Click the render button to render.
The plaster material of the object itself is replaced by a metallic texture, resulting in changes in reflection and gloss on the metal surface. However, we see a large area of gray in the background of the painting because we have not yet added the scene settings.

4.2 Setting the Scene
Select the Scenery Black Reflexive icon to import scene in the TechGems module.
The scene files provided by TechGems have already set up the corresponding scene models and lighting, and the material properties have also been configured. We need to adjust the camera angle to modify the rendering image and render again to obtain the effect.

4.3 Environmental Setup
Adding environmental settings can make the surface colors and variations of the objects richer and more layered, presenting a more realistic scene.
Enter the Environment settings of the Flamingo parameter settings in the attribute editor, select 3 Color Gradient, and adjust.
Click rendering to enrich the metallic surface of the object with light and shadow, making the changes in brightness and darkness layered; however, the object’s shadow is too strong, and the transparency of the gem has not yet been displayed, requiring further adjustment of the settings.
Environmental color change settings
Test rendering
4.4 Adjusting the Bounces Settings
Set reflection to 12; this setting can increase the reflection value of transparent materials, making the object glossy, brighter, and richer in layers when reflecting.
Set the Transparency bounce value to 12. The larger the bounce value, the more times light refracts and reflects inside the object, resulting in richer color variations in transparent objects, thus achieving a more translucent effect.
Clicking render again, the shadows of the objects in the image are noticeably softened, making them more realistic; the color variations of the gemstones are evident, appearing more transparent; finally, after adjusting the antialiasing settings of the image, the work is complete.
Setting Reflection and Bounce Values
Test rendering
4.5 Setting the Antialiasing Capability and Detail Level of the Image
We also need to adjust the corresponding parameter settings during the final rendering. To improve the rendering quality of the image, select High > 16x (slow) in the Antialiasing options for high antialiasing capability. At this point, the rendered image’s objects, shadows, reflections, and other details will not have jagged edges, but choosing this setting will significantly extend the rendering time.
Open the Render Mesh option to set the rendering detail level, and select Smooth & slower in the Render Mesh quality section. This setting produces a more delicate image. The system also provides Custom manual parameter settings, extending the rendering time.
Finally, you can appropriately change the rendering size (adjust the corresponding height and width according to the actual aspect ratio of the image). After setting all the parameter data, you can proceed with the final rendering to obtain the final rendered effect image.
