3Ds Max

1
3Ds Max

• Working with 3Ds Max.

2
Working with 3Ds Max.

• To Create a good quality scene or image using 3Ds
  max theres some requirement that must exist in
  the scene in order to produce a good product.
• The object.
• Materials.
• Lights.
• Cameras.
• Animations.

3
Objects.

• The objects that can be represented in the scene
  can be predefined primitives and models or user
  designed models.

4
Predefined Models.

• Standard primitives the simple primitives
  offered by 3Ds Max like ( box, sphere , cylinder
  , tours , etc .) can be created from the create
  panel or the create menu.
• Extended primitives more complex primitives
  that are defined and offered by 3Ds Max like
  (chamfer box, chamfer cylinder, capsule , hose ,
  hedra , oil tank , etc ..)

5
User Designed Models.

• Any model that have been designed and modeled by
  the user is a User Designed model. Theres so many
  modeling techniques like (poly , mesh , patch and
  NURBS ) modeling.

6
Modeling Techniques .

• Poly and Mesh are very similar but the poly is
  better than the mesh it has more modeling tools
  and more flexible than the mesh modeling it can
  be considered as an developed version of the mesh
  modeling.
• NURBS (Non-Uniform Rational B-Splines) is a
  technique for interactively modeling 3D curves
  and surfaces.
• Patch the same as the ploy but with different
  tools for modeling.

7
Materials Textures

• Theres a a difference between the material and
  the texture.
• Texture is the image or the picture the will be
  applied to one property of the Material like
  (diffusion color , opacity , bump , reflection
  , etc.. ).
• To apply a texture to a model we apply the
  texture of image to the diffuse property of the
  material associated to the model.
• The material is the skin that covers the model
  theres a set of properties associated to each
  material changing these properties produces a
  different material .

8
Materials Textures continue.

• Diffuse the color or texture of the material.
• Opacity the transparency of the material.
• Self Illumination the self shining degree of
  the object color or texture.
• Bump to assign a prominence texture to the
  material (to increase the details of the objects
  with out the need for complicated modeling.)
• Reflection to assign a reflection map to an
  object to represent the global environment
  reflection that can occur on the object if it was
  really reflective object.

9
Materials Types.

• Standard Material the default material
  supported by the 3Ds Max and have all the
  previous properties .
• Raytrace creates fully raytraced reflections and
  refractions. It also supports fog, color density,
  translucency, fluorescence.
• Architectural provides a physically accurate
  material. It is especially intended for use with
  the default scanline renderer and radiosity.
• Mental ray are provided for use with the mental
  ray render.

10
Materials Types continue.

• Matt\Shadow is specifically for making an object
  into a matt object that reveals the current
  environment map. A matte object is effectively
  invisible in the scene, but it can receive
  shadows cast onto it from other objects.
• Shell is for storing and viewing rendered
  textures.
• Advanced Light override is used to fine-tune the
  effects of a material on radiosity or the light
  tracer. This material is not required for
  calculating advanced lighting, but it can help
  improve the result.

11
Materials Types continue.

• LightScape helps support import and export of
  data from the Lightscape product.
• Ink 'n Paint gives a cartoon appearance to
  objects.
• The DirectX 9 Shader enables you to shade
  objects in viewports using DirectX 9 (DX9)
  shaders. To use this material, you must have a
  display driver that supports DirectX 9, and you
  must be using the Direct3D display driver.
• Other material types fall into the category of
  Compound materials

12
Compound Materials.

• Blend mixes two materials on a single side of a
  surface.
• Composite mixes up to 10 materials, using
  additive colors, subtractive colors, or opacity
  mixing.
• Double-Sided lets you assign different materials
  to the front and back faces of an object.
• Morpher uses the Morpher modifier to manage
  multiple materials over time.
• Multi/Sub-Object uses the sub-object level to
  assign multiple materials to a single object,
  based on material ID values.
• Shellac material superimposes one material on
  another using additive composition.
• Top/Bottom material lets you assign different
  materials to the top and bottom of faces of an
  object.

13
Lights.

• Lights are objects that simulate real lights such
  as household or office lamps, the light
  instruments used in stage and film work, and the
  sun itself. Different kinds of light objects cast
  light in different ways, emulating different
  kinds of real-world light sources.

14
Target Spotlight.

• A spotlight casts a focused beam of light like a
  flashlight, a follow spot in a theater, or a
  headlight. A target spotlight uses a target
  object to aim the camera.

15
Free Spotlight.

• A spotlight casts a focused beam of light like a
  flashlight, a follow spot in a theater, or a
  headlight. Unlike a targeted spotlight, a Free
  Spot has no target object. You can move and
  rotate the free spot to aim it in any direction.

16
Targeted Directional lights.

• Directional lights cast parallel light rays in a
  single direction, as the sun does (for all
  practical purposes) at the surface of the earth.
  Directional lights are primarily used to simulate
  sunlight. You can adjust the color of the light
  and position and rotate the light in 3D space.

17
Free Directional lights.

• Unlike a targeted directional light, a Free
  Direct light has no target object. You can move
  and rotate the light object to aim it in any
  direction.

18
Omni light.

• An Omni light casts rays in all directions from a
  single source. Omni lights are useful for adding
  "fill lighting" to your scene, or simulating
  point source lights

19
Skylight light.

• The Skylight light models daylight. It is meant
  for use with the Light Tracer You can set the
  color of the sky or assign it a map. The sky is
  modeled as a dome above the scene.

20
Cameras.

• Cameras present a scene from a particular point
  of view. Camera objects simulate still-image,
  motion picture, or video cameras in the real
  world.

21
Animation.

• The basic way to animate is quite simple. You
  animate the transform parameters of any object to
  change its position, rotation, and scale over
  time. Turning on the Auto Key button, then moving
  the time slider places you in a state in which
  any changes you make will create animation for
  the selected objects in the viewport.

22
Animation Types.

• There is a lot of animation types supported by
  3Ds Max.
• Standard animation changing the objects
  parameters on time using key frames then the
  program will calculate the intermediate frames .
• Constrains animation where the object animated
  using a certain constrain (sound wav, path, noise
  , etc..)
• Motion Capture Animation motion capture
  animation is an animation method where humans use
  machines to capture their movement to assign it
  to other 3D character models or any other model.

23
Animation Types.

• Characters Animation where user can use a
  certain behavior in the animation (steps , speed
  , etc ..).
• IK animation type of animation used to animate
  Machines and electronic robots where the arms of
  the object animated under certain constrains and
  behavior (can be used for character animation .)
• Physical Computation where you assign a
  physical parameters to each object on the scene
  and global environmental physical values like
  (gravity , wind direction , wind speed , objects
  mass , etc ..)

24
Good Scene Requirements.

1. Accurately Modeled Models.
2. High level Detailed materials.
3. Accurate lights distribution (supporting indirect
   lights will increase the image realty in a good
   way )
4. Cameras ( the picturing process and the setting
   of the camera helps in increasing the final image
   quality .)
5. Global Environment .
6. Animation.
7. Special Effects. (if needed)
