Polygonal Text Settings When you create polygonal text, Maya provides option that you can set to display and create your text for subsequent polygonal-type editing. Triangles Three sided polygons are created. This is the default. Tessellation Methods Standard fit This is the default tessellation method. It is adaptive tessellation, meaning that following option is used to determine when to stop the tessellation. The tessellation stops at the fractional tolerance value you set. If there is an edge shorter than the Minimal Edge Length, the tessellation stops on that edge. If the surface is flat enough with in the edge, the tessellation stops here. General Set the tessellation method to General to display the following options. Unless Use chord height or use chord height ratio is turned on, a uniform tessellation is performed. Each span is split into a number of polygons depending on the number U and V values you set. Count Set the tessellation method to Count to display the Following slider. Count slider is used to determine how many polygons the surface can be tessellated into. Control points This tessellation method converts the Nurbs model to polygons while matching the CVs of the original Nurbs surface. There are no other options for this operation. Extruding You can pull faces and edges out from polygonal objects using the Extrude Face and Extrude Edge commands. Extruding Faces You can extrude faces either interactively or directly through the option window. Select Edit Polygons > Extrude Face ,set whatever option you need and click the Extrude Face button.
you are not happy with results, select Undo from the Edit menu, change the Extrusions settings in the channel Box or Attribute Editor and press Enter. Extruding Edges You can extrude edges either interactively or directly through the option window. If you prefer to set the options first and then extrude the edges, Select Edit Polygons > Extrude Face. Duplicating Faces You can duplicate and transform faces interactively or directly through the option window. Select the faces of the object you want to duplicate. Press the right mouse button and select Face or press F11.
You can also Duplicate Faces through Edit Polygons > Duplicate Face. Extracting Faces While Extracting ,Maya disconnects the selected Faces from the original shape, by duplicating the appropriate edges and vertices. The extracted faces become their own shell with in the object. This is the another way to make holes in the object while retaining their original faces. Seperating the extracted faces creates distinct polygons out of the faces and the original object. To extract Faces

Polygon Selection With Edit Polygons > Selection menu, you can constrain the selection of components to a specified area of a polygonal model and perform operations on those components in that specified area only without disturbing the rest of the model. Select Edit Polygon > Selection >Grow Selection Region to increase the number of components you initially selected. Selecting Boundaries You use Edit Polygons >Selection >Select Selection Boundary to define the boundary of the current selection region. It is a quick way to select the boundaries of whatever is currently selected. Selection a band of edges Use Edit Polygons > Selection > Select Contiguous Edges to select a contiguous band of edges around model. With this you can select one edge, choose select Contiguous Edges, and it will select the rest of the edges in the center automatically. Max 2d Angle ,Max 3d Angle These settings determine how far the selection continues based on the angles between edges. The 2d angle refers to angle made by the surface topology, regardless of the surface's shape. The 3d angle refers to angles made by the surface's shape, as measured in world or local space. <TABLE border=0 cellSpacing=0 cellPadding=0 width="100%"> <TR> <td> </TD></TR> <TR> <td><TABLE border=0 cellSpacing=0 cellPadding=0 width="100%"> <TR> <td class=gray2 vAlign=center width=96 align=middle> [You must be registered and logged in to see this image.] </TD><td class=gray2 vAlign=center width=398 align=middle>ExpertRating MAYA Certification - Get Certified Now!! </TD></TR></TABLE></TD></TR></TABLE> |
