Scene Data

This chapter describes procedures and precautions for creating scene data using NintendoWare in Softimage.

Camera
Light

Camera

• Camera Types

  Supported camera types are: Perspective, Telephoto, Wide Angle, and Orthographic.

• Cameras that are not output

  A camera will not be output if its Visibility property View Visibility is OFF.

• Aspect Ratio

  The aspect ratio is set by selecting Primitive > Pict. Ratio under Camera Properties, or Projection Plane > Film Aperture (Fixed Aspect Ratio OFF).
  

• Angle of View

  Angle of view is set by selecting Primitive > Field Of View > Angle under Camera Properties or Projection Plane > Film Aperture (Fix Aspect Ratio ON). Since vertical Field of View (Fovy) is output to the intermediate file, if Primitive > Field Of View is set to Horizontal, convert it to Vertical Field of View before exporting. The relationship between Horizontal Angle of View and Vertical Angle of View is determined by the Aspect Ratio.
  The relationship between the Vertical Field of View (Fovy) and the Horizontal Field of View (Fovx) is given by the following formula:

  Fovy = 2 * atan( tan( Fovx * 0.5 ) / aspect )

Lights

• Light Types

  Supported light types are: Infinite, Point, and Spot.
  Render > Edit > Ambience converts light into ambient light. However, there can only be one ambient light.

• Lights that are not output

  A light is not output if the Visibility property View Visibility is not animated and is OFF.

• The Spotlight's Visibility property

  A spotlight is not output if either its own Visibility or the Visibility of Spot_Root is OFF.

• Light Contribution

  If the light property Light Contribution > Specular is ON, then the color value is output as specular color.
  If it is OFF, then black is output to the specular color.

  If the light property Light Contribution > Diffuse is ON, then the color value is output as diffuse color.
  If it is OFF, then black is output to the diffuse color.

• Ambient color

  Black is always exported for the ambient color of Infinite, Point, and Spot light types.

• Specular Color 0, Specular Color 1

  The intermediate file can have two settings for specular color, but the same value is output for both from Softimage.

• Exportable Attributes

  Attributes that can be output to intermediate files are collected below.

  • The light kinematics Translate and Rotate (Global Coordinates)
  • The light Visibility property View Visibility (except for Ambient Lights)
  • The light Color, Cone Angle and Spread (Cone Angle and spread are for Spot Lights only)
  • Ambient Light Color
  • Intensity is output as the alpha component of the light color. (Valid values range between 0.0 and 1.0. (Valid values are 0.0 through 1.0 and correspond to alpha values ranging from 0 to 255 in the intermediate file.)
    However, 1 is always exported for the alpha value of the ambient color of Ambient Lights and Lights.
  • The kinematics Translate of the spot light Interest node (Global Coordinates).
