Chapter 6. Creating Realistic Rendering Effects
Any geometry model in a 3D scene is composed of vertices, texture, lighting, and shading information. Rendering is, in the graphics pipeline, the last major step, generating the image from the defined model with a number of visible features, for example, the brightness, color, and detail of the surface that the viewer sees. OSG has encapsulated almost all of the OpenGL's rendering interfaces, including lighting, material, texture, alpha test, image blending, fog effect, as well as the implementation of vertex, geometry, and fragment shaders in OpenGL Shading Language.
This chapter will give a detailed introduction to
- Understanding the concept of a state machine and the encapsulation of it in OSG
- How ...
