Week 17 Vocab & Terminology
Class hours: 9:40am – 2:05pm
Mr. Cronin
Mr. Herr
Quizzes will be first thing Thursday morning – 10 questions. Quizzes are 15% of your CAWD grade. The other 35% is your class work, and final 50% worker traits.
- Final Gather is a Mental Ray algorithm used in 3D computer graphics rendering, that simulates indirect illumination by light-energy bouncing in a given world.
- Final Gather collects information from all of the textures and lights in any given room and calculates how the light would bounce around the room and absorb color energy from certain objects.
- To use Final Gather in 3d Studio Max you have to turn on the Mental Ray Renderer. You can do this in the bottom of the “Render Scene” Window in the “Common” tab (Shortcut: F10), under the assign renderer tab.
- mr Area Spot stands for mental ray Area Spot, and acts like a normal spot for the mental ray renderer. It is different from a normal spot light in that it allows you to use indirect illumination.
- When using mr Area Spot, turn on the manual settings for “mental ray Indirect Illumination“. This allows to manually adjust how much energy a light releases and how many photons it adds to global illumination.
- When using Final Gather, we use the “Arch & Design” material presets. These presets contain settings for Final Gather and allow for light to absorb colors and/or be reflected by the material.
- In Final Gather, 3ds Max places a bunch of imaginary points (FG Point Density) around a scene on objects. Then Max calculates how a number of light beams (Rays per FG Point) would bounce around each imaginary point.
- You can smooth out the light beams (Interpolate Over Num FG Points) so rather than having a bunch of light points all over the scene, you will have smooth transitions between light sources.
- If your scene is to dark, or a certain object absorbs to much color from another object, you can use Ambient Occlusion. This allows an object to reflect a certain color, different from the light bouncing around a room.
- Exposure control (8 on keyboard) is just like using a Camera or Photoshop settings in Max before you render your full size image. It allows you to adjust brightness, contrast, mid tones, and physical scale.
