Mastering 3D Rendering Techniques Quiz

Layering shaders are considered physical based shaders. Therefore, they should interact only with lights that are physically plausible: that is, the light should act like a realworld light

Using raytrace shadows produces more accurate results, but it often takes a little more time and processor power to calcultae

Ambient occlusion occurs when indirect light rays are prevented from reaching a surface. Ambient occlusion is a soft and subtle type of shadowing. It's usually found in the craks and crevices.

With a 3D texture, objects appear to be carved out of a substance, such as rock or wood. You can scale, rotate and move 3D textures interactively in a scene view to achieve the desired results.

A transparent surface can change the direction of the light rays as they pass through the surface. The bending of light rays can distort the image of objects on the other side of the surface

Describes how a light ray is reflected off a rough surface.

Cast shadows are created when an object blocks the rays of light coming from a light source

Area lights and image based lighting work best with layering shaders, since their visible light corresponds with the light that they actually cast.

This effect describes the amount of reflection and refraction that occurs on a surface as the viewing angle changes.

This is the region of sharp focus in a photograph

Using the OpenEXR file format, you can write each pass as a single layer within the file itself

Render layers can be used to create a balance between efficiency and flexibility

_________are best used to isolate geometry shaders, and lighting to create different versions of the same animation.

When maya renders an image, it collects data from the scene and stores it in a temporary image known as

A free photoshop plugin that can read openEXR format with multilayer render passes.

Using ___________________. You can separate the reflections, shadows, diffuse color, ambient occlusion, specular highlights, and so on, into images or image sequences, which can be thhen be reassembled in compositing software

Render passes divide the output created by a render layer into separate images or image sequences.

___________are way to automate the organization of your renders. If your scene has a lot of layers, cameras, and passes.

EXR-IO a free photoshop plugin that can read openEXR format with multilayers render passes

Render layers are best used to isolate geometry, shaders, and lighting to create different versions of the same animation

Sets the distance the brush moves on the polygon surface before a new brush stroke is created

____________ Controls the orientation of the primitive to be in the direction of the brush stroke without modifying the bend

XGen Description store settings for positioning, generating, and rendering primitives. Each Description controls primitives on the selected faces of the mesh surface, which are called XGen patches. You can add any number of Descriptions to a polygon mesh. Descriptions are contained by and organized in Collections

Groomable splines are non-renderable spline primitives that you first shape using the brushes, and then preview and render as default spline primitives

XGen Collections let your organize related sets of Descriptions for a character or scene. You can create a Collection for a character or scene element and add each Description to the Collection.

Sets how the brush storke falls off to no effect. You can select a Gauss, Smooth, Linear, or Impulse distribution

___ is an abitary primitive generator

It gives you the ability to control attributes such as size and shape.

This controls the bend of the primitive in the direction of the brush stroke without modifying the orientation.

Use the grooming brushes to add, scale, sculpt, and position groomable splines for your character's hair or fur.
