Editable Poly Working With Editable Poly Objects George Atanasov Telerik Corporation www.telerik.com
Editable Poly • Editable poly – five sub-object levels • Vertex • Edge • Border • Polygon • Element The poly object's faces are polygons with any number of vertices
Advantages • Editable poly options • Transform or Shift-Clone selection as with any object • Options supplied on the Edit rollouts • Pass a sub-object selection to a modifier higher in the stack. To convert object to editable poly: Quad menu > Convert to Editable Poly Modify panel > Choose Convert to: Editable Poly.
Command Buttons • Command button – provides specific command or function to apply • Two ways of using the commands • Direct manipulation • Interactive manipulation Note: Some buttons, such as Flip, operate on the mesh immediately, with no viewport manipulation required.
Show End Result • Show end result – Command Panel -> Show end result toggle • Enables you to see the result of all modifiers while editing on lower level
Selection Rollout Selection Rollout Commands
Selection Rollout • Selection rollout contains • Buttons for accessing sub-object levels • Display Settings • Information about selected entities • Object level commands • Sub-object level commands
Selection Rollout • Sub-object level buttons • Vertex – Turns on Vertex sub-object level • Lets you select a vertex beneath the cursor • Region selection selects vertices within the region • Edge – Turns on Edge sub-object level • Lets you select a polygon edge beneath the cursor • Region selection selects multiple edges within the region
Selection Rollout • Sub-object level buttons • Border – Turns on Border sub-object level • Lets you select sequence of edges that borders a hole in the mesh • Border edges have faces only on one side of them • Polygon – Turns on Polygon sub-object level • Lets you select polygons beneath the cursor • Region selection selects multiple polygons within the region
Selection Rollout • Sub-object level buttons • Element – Turns on Element sub-object level • Lets you select all contiguous polygons in an object • Region selection lets you select multiple elements
Selection by vertex • Selection by vertex • Select sub-objects by vertices they use • By clicking on a vertex all objects using it are selected
Ignore Backfacing • Ignore backfacing • When on selection of sub-objects affects only those facing you • When off, region selection includes all sub-objects, regardless of the direction they face
Selection Transformation • Shrink - reduces the sub-object selection area • Deselecting the outermost objects • If selection size cannot be reduced, the remaining objects are deselected • Grow – expands the sub-object selection area • Adds the closest outward objects to the current selection For this function, a border is considered to be an edge selection.
Selection Transformation • Ring – expands an edge selection • Select all edges parallel to the selected edges • Loop – expands the selection as far as possible in alignment with selected edges Ring and Loop applies only to edge and border selections
Selection Information • Selection information – text display • Information about current selection • If zero or more than one sub-object is selected, the text gives the number and type • Else the text gives the identification number and type of the selected item
Soft Selection Rollout Working With Soft Selection
Soft Selection • Soft selection controls • Apply smooth falloff between selected sub-objects and unselected • Partial selection value • Affects • Move function • Rotate function • Scale function • Deformation modifiers
Soft Selection Curve • Soft Selection Curve – Graphically displays how Soft selection will work • In the center of the X axis is the direct selection • The partial selection will be affected with force depending on the Y value of the current object
Soft Selection Parameters • Edge Distance space • Edge distance – Edge Distance spinner • Distance in edge count • Absolute Distance space • Absolute distance – Falloff spinner • Distance in current units • Pinch spinner – affects the curve of the effect
Soft Selection Parameters • Bubble spinner - Sets the relative "fullness" of the region • Expands and contracts the curve along the vertical axis In older versions of 3D Studio Max is displayed only the right symmetrical half of the Soft selection curve
