1. Rendering view by view Presented By: HOSSAM M. ZAYED By: Darlene A. Brady Web Address: WWW. ArchitectureWeek.com Topic Number: 153 Date: 11 July 2001

2. Briefing Digital rendering enables View By View to preview images in a matter of seconds or minutes, allowing them to iteratively refine lighting, viewpoints, and other detail. Manual rendering gives an illustration a human touch,this argument has some validity. Nevertheless experienced hands can produce Synthetic Renderings with qualities to satisfy the demanding traditionalist. Creating a beautiful, true to-life image "is like drafting a new project design one must experiment and practice until satisfied with the results Natural view painted by an Artist Natural view painted by an Artist The same view rendered in 3D MAX The same view rendered in 3D MAX

3. Synthetic Rendering = 3D digital objects or scenes assigned physical based material properties + + lighting conditions Example : Example : The Emperor's Tomb Game By : Boryslawski & Israel By : Boryslawski & Israel This technique is used in a variety of projects including games and architectural proposals and reproductions Synthetic Synthetic Rendering Rendering Steps Steps Tools Used Tools Used (1) 3D modeling The dining chamber rendered with basic color (no texture & light). The dining chamber rendered with basic color (no texture) and ambient and electric light. A fully rendered view of the dining chamber with ambient and electric light. Form-Z ProgramElectric Image Photoshop & Electric Image (3) Texturing(2) Lighting View By View Synthetic Rendering

4. Setting the Lighting Light Types Used to focus on objects and to create shadows. 1) Spot Light 2) Parallel Light 3) Radial Light Creates an effect analogous to sunlight, Used to augment ambient light and create atmospheric effects. Object Spot light Source Fall off area Hot spot area Elevation showing spot light Diverging Shadow Soft edged falloff Object Parallel light Source Hot spot area Elevation showing Parallel light Straight shadow Sharp edged hot spot Object Radial light Source Elevation showing Radial light Spreading Light with soft edged diverging shadow Fall off area Hot spot area

5. Setting the Lighting Placing Light Types Using View By View Example : A Bedroom Lamp with different light types 1) Ambient light Source is added first to provide general lighting to the scene 2) Spot light Source is added to lamp looking down to form lamp light down on table 3) Spot light Source is added to lamp looking up to form lamp light parabola on wall 4) spot light Source is added to lamp looking down with shadow effect to form shadow of the lamp cover 5) spot light Source is added finally to provide additional general lighting to the scene and lighten the dark shadow areas

6. Setting the Lighting Adding Light Effects to The Scene The Qin tomb chamber with mist effect that gives reality to scene The Qin tomb chamber after adding volume light effect to focus on the tomb it self and add dramatic effect Israel used the radial light with the "fog" attribute to create an impression of dustiness In the tomb chamber, unseen radial and spotlights work in tandem. The air is filled with dust. Sunlight streams through an unseen opening above and brings into focus the figure of the Emperor Qin enshrined in his unexcavated tomb.

7. Working with Textures 1 Getting Materials Textures were created with Photoshop directly from scanned photographs of artifacts and buildings of the same time period as the tomb. The scanned images were carefully cropped and adjusted so the texture patterns tile smoothly, without appearing repetitive, or tiled, when mapped to objects. 2 Processing Material Images Scanner Photoshop Scanned Pictures Books & magazines Scanned Picture Processed Map

8. Working with Textures In Electric Image, texture mapping tools are used to apply the pixel images to object surfaces, so the objects look like the texture was painted on. 3 Mapping textures The fabric texture used on the bed curtain in the emperor's chamber. A rendered view of the emperor's chamber without textures. a rendered view of the emperor's chamber with textures. The Emperor's Tomb Game Example : Example : By : Boryslawski & Israel By : Boryslawski & Israel emperor's chamber

9. Working with Textures 4 Applying Material physical properties It is important to assign the appropriate material attributes, such as whether an object is shiny, dull, matte, metallic, or glowing for each object in a scene. Example : A Bedroom Lamp with different Material Effects Wall texture seems planar Bump map is added to wall texture Lamp body marble reflects nothing Reflection map is added to Lamp body marble Lamp cover is opaque Opacity property is applied to lamp cover Lamp base brass specular is non realistic Lamp base brass Specular property is adjusted.
