Rendering In a Nugraf scene many cameras can be positioned, however only one can be active at a time. Several rendering methods can be used to produce very different results. One can choose from wireframe or hidden-line wireframe methods. Nugraf also provides a method of its own in which you can render anything from simple images, composed of few polygons with only a few colors, to photographs with high realism of complex scenes composed of thousands of textured polygons and shades. Finally, flat, Gouraud or Phong shading models can be applied to the scene.
All lights have a parameter, intensity , which expresses the power of each light.
It is possible to simulate a great number of materials using the definition of a surface. The attributes of a surface are reflectance properties, color of each component of the reflected light, textures, opacity and the reflection map. Reflection maps can be with planes, spheres or cubes. Several general aspects related to the rendering process can easily be defined. Nugraf offers a solution to the aliasing problem.
