Blender 2.5 lighting and rendering : bring your 3D world to life with lighting, compositing, and rendering
Annotation Blender 3D is a popular, open source modeling and animation package. It is used for game design, architectural visualization, character design, animation, and still images. However, creating believable lighting and texturing is difficult in any 3D program.
This step-by-step tutorial aims to familiarize you with Blender's new interface and basic features as well as take a look at what it takes to produce a believable scene using lighting, texturing, compositing, and rendering.
By using the example of a tricycle in an outdoor scene you will learn to establish an effective workflow to increase your productivity. You will also thoroughly studying the scene and deciding how your tricycle would look on a sunny, cloudless day using Blender lamps. Not just that, you will also learn to implement your decisions by applying a 3-point light rig, adjusting the color of the lights, adding shadows, and using light groups to control the lighting. You will learn to add ambient occlusion effects to your scene by using both ray-traced and approximated ambient occlusion algorithms. A mesh example shows you how to give a particular look or "feel" by adding and editing materials. You will light a wine bottle on a table by taking a look at lighting interior spaces and how to create complex light rigs and custom UV textures for your scenes using Blender's UV editing capabilities. You will create a custom UV map, export it as a file type Blender can read, and finally add your UV map to the wine bottle mesh. In the same example you will add wood material to booths. You will further enhance the background by adding wallpaper, giving color and metallic tint to the lamps, and adding material to light bulbs. You will look at lighting techniques used in scenes that include both interior and exterior light sources in a scene that has sunlight traveling in through the window and a light bulb hanging from the ceiling.
A step-by-step guide, with practical examples, that builds up your knowledge of lighting and rendering in Blender and helps you to implement these various techniques in your own work
What you will learn from this book :
Optimize Blender's Internal Renderer for your projects
Establish a well-tested and efficient workflow to constantly produce high-quality work
Apply both ray-traced and approximated ambient occlusion to your scene
Configure the default settings of ambient occlusion by manipulating parameters such as Sampling, Attenuation, and Influence
Configure settings found with Blender's materials to create, duplicate, and add special effects such as transparency and reflections to your materials
Modify World settings to add a gradient effect to the background to create a more interesting render
Separate your scene into layers to light the scene using a complex light rig
Construct a complex light rig and link lights to specific layers
Add indirect lighting and integrate it with your scene
Add textures to materials
Enhance your scene by using Blender's node compositor
Simulate light "bending" with 3D lighting techniques
Illuminate dark corners and crevices in your scene using ambient light
Set up the basic material and then add textures and look at many different materials with varying properties such as plastic, metal, glass, wood, brick, marble, and concrete Approach
Each chapter develops a different aspect of a Blender technique. The book is essentially a step-by-step tutorial, which builds up your knowledge throughout. It has practical examples such as lighting a tricycle in open space, lighting a wine bottle on a table, and lighting a room that has a lamp as well as sunlight coming in through the window. These examples will show you how to implement the different Blender techniques in your work. Who this book is written for
If you are a Blender user and you want to improve the quality of your renders, this book is for you. You need to have experience in Blender and know your way around the Blender interface. You may be a professional or freelancer or hobbyist willing to increase the quality of your portfolio and interested in adding perfection to your renders.
