Manipulate objects and scene elements within a three-dimensional production environment
Assessment Strategies
Projects
Criteria
Viewports are navigated and configured to view scene elements from effective perspectives
Objects are created, selected, transformed, shown, and hidden using effective scene controls
Translation, rotation, and scale are applied using axes and coordinate space
Object pivot points are positioned and used effectively for the intended transformation
Scene files are created, saved, opened, and maintained without loss of required scene data
-
Configure materials and lighting to define the visual appearance of a 3D scene
Assessment Strategies
Projects
Criteria
Materials are created, assigned, and modified to produce the intended surface appearance
Light types are selected and positioned according to the intended illumination of the scene
Light properties are adjusted to control the intensity and appearance of illumination
Shadows correspond effectively to the placement and properties of scene lighting
-
Manipulate polygonal mesh components to modify three-dimensional forms
Assessment Strategies
Projects
Criteria
Vertices, edges, and polygons are identified and selected according to the intended modification
Mesh components are transformed to modify the shape of an object while maintaining the intended form
Component selection methods are used to efficiently isolate the portions of a mesh requiring modification
Changes to mesh components maintain appropriate connections with neighboring geometry
-
Construct three-dimensional forms using polygonal modeling techniques
Assessment Strategies
Projects
Criteria
Extrusion is used to create new geometry that extends the intended form
Beveling is used to modify edges and surfaces according to the intended shape
Edge loops are created and positioned to provide geometry required for the intended form
Mirroring and object-combination techniques are used appropriately to construct complete forms
Overlapping or coplanar geometry is identified and corrected when it produces unintended visual artifacts
-
Manipulate keyframes and animation curves to control motion over time
Assessment Strategies
Projects
Criteria
Keyframes establish the intended values of animated properties at specific points in time
Frame rate and playback settings are configured effectively for the intended animation
Animation curves are interpreted to identify changes in value and motion over time
Keyframe timing and values are adjusted to modify the resulting motion
Curve slopes and tangent handles are manipulated to control transitions between keyframes
-
Apply fundamental animation principles to communicate motion, weight, and physical behavior
Assessment Strategies
Projects
Criteria
Timing and spacing communicate the intended speed and weight of an animated object
Squash and stretch communicate changes in force and motion while maintaining the recognizable form of the animated object
Changes in motion convey believable acceleration, deceleration, and changes in direction
Animated movement communicates the intended sense of weight and physical behavior
Animated movement conveys a sense of character, personality, or life appropriate to the intended action
