Blender 3D: Noob to Pro/Glossary A[edit] B[edit] Background image: a 2D image ("picture") that is placed "behind" the entire 3D scene, like a backdrop on a movie set. Blender permits the placement of these images in all six directions from the origin: back, front, top, bottom, left, right.Bake: to precompute computationally-intensive elements of an animation. For example, in a physics simulation involving the behaviour of fluids or clothing, you would set up the physical parameters, then compute (bake) the positions and shapes of the objects over the duration of the animation. C[edit] Caustics in optics is a bundle of light rays. D[edit] Depth of Field (DOF) is the distance in front of and behind the subject which appears to be in focus. E[edit] Environment Maps (EnvMaps) is the method of calculating reflections. F[edit] G[edit] GE is Game Engine.Global Illumination (GI) is a superset of radiosity and ray tracing. H[edit] I[edit] J[edit] K[edit] L[edit] M[edit] N[edit] Nabla. normal[0]= s0-s1 normal[1]= s0-s2 normal[2]= s0-s3
