3D Studio Max

Features & Benefits

• Modeling & Animating tool by Kinetix.• Used various fields such as character animation,

game development, and visual effects production.• User friendly interface and easy to use. • Object oriented design - Objects in Max are

analogous to objects in C++ (We can approach by programming plugins)

• High quality.• Many artists use.

Modifying Object

• Click on “Modify” button to right of “Create” button.

• Click on the “Bend” modifier and adjust the angle to your liking.

Box does not appear to be bent, because not enough Box does not appear to be bent, because not enough segments are used to display it. segments are used to display it.

• Select “Box” on the Modifier Stack drop down menu.

• Change the numbers of segments in the creation parameters.

Modifier Stack

• Record of sequence modeling operations:– Earliest operations on bottom of stack.– Latest operations on top of stack.

• Allows user to return to earlier operations and change the way they were done.

• The user may, delete and re-order operations on the stack.

Editing

Converting a Parameterized Object to an Editable Mesh

• Create a sphere.

• Add a “Mesh Select” modifier.

• Indicate “Select by Vertices”.

At this level of the modifier stack, the object is a mesh composed of At this level of the modifier stack, the object is a mesh composed of vertices, faces and edges. It is not a parameterized sphere object. vertices, faces and edges. It is not a parameterized sphere object.

Editing an Editable Mesh

• Go to an orthographic viewport.

• Click on the “Select Object” arrow on the Main Toolbar.

• Drag a box around the vertices in the upper hemisphere.

Editing Editable Mesh

• Add an Xform modifier, under “More” on the Command Menu.

• Choose “Non-Uniform Scaling” on Main Toolbar.

• Choose “Parent” coordinate system on Main Toolbar.

• Choose “Transform Coordinate Center” on Main Toolbar.

Max Provides Lots of Options for Controlling Transformations

• Choice of coordinate system: World, Parent, Local, etc. (Determines coordinate axies.)

• Choice of “Pivot”: Object’s own pivot, Selected objects’ collective pivot, Center of coordinate system. (Determines centers of scaling and rotation.)

• Constraining action to lie along one or two named axies.

Animation

Linked Object Animation

• Draw 3 cylinders at the front viewport. and select one at the top of three.• Click on “Select and Link” at the right side of

“Redo” Button. • Drag mouse to middle cylinder.• Select middle cylinder and drag to bottom cylinder

as same before.• Try to move or rotate each cylinders.• Click Hierarchy Tab on Control Pannel and click

“Affect Pivot Only” and move each cylinders pivot to desired position.

Linked Object Animation• Click “Affect Pivot Only” once again to disable pivot mode.• Try to rotate or move each cylinder then you will see how

the linked hierarchy is constructed. • Activate Front viewport and select bottom cylinder. • Click “Animate” button and move Time Slide Bar to frame

50.• Rotate cylinder about 45 degree. (or right click on the

“Select and Rotate” button to input value manually)• It means that cylinder moves 0~45 degree in 50 frames.• Move Time Slide Bar to frame 100(You can see previous

cylinder moves) and rotate cylinder about –45 degree.( or any value you want )

• Do the same above with other cylinders.• Click Play button at the right side of Animate button and see

how linked cylinders move.

Assignment# One Rigid Object (Save as .max)

Homework #1 Due to 3/26 PM 12:00 (3/27 AM 0:00)

• Build 2 object without animation follow.

* Car, Airplane, Ship, Building etc.(not linked)

* Jointed Robot-like object. (Don’t be pressed to make humanoids. Whatever linked

thing you want.)

• With Robot, assign pivot and animate.

(Snake, Bipedal, 4-legged, Industrial Robots etc.)• Option

For non-Robotic object, animate with 3 controllers each.
