FX Composer 2.5 Getting Started User’s Guide MTL Illumination Models illum_0 illum_1 illum_2 illum_3 illum_4 illum_5 illum_6 illum_7 illum_8 illum_9 illum_10 Description Color on and Ambient off Color on and Ambient on Collada Blinn common profile Highlight on Transparency: Glass on, Reflection: Ray trace on Reflection: Fresnel on and Ray trace on Transparency: Refraction on, Reflection: Fresnel off and Ray trace on Transparency: Refraction on, Reflection: Fresnel on and Ray trace on Reflection on and Ray trace off Transparency: Glass on, Reflection: Ray trace off Casts shadows onto invisible surfaces FX Composer translates these illumination models with COLLADA FX Common profiles as such: MTL Illumination Models FX Composer 2 COLLADA FX Common Profile illum_0 illum_1 illum_2 illum_3 illum_4 illum_5 Collada Constant common profile Collada Lambert common profile Collada Blinn common profile Not supported, default to Collada Phong common profile Not supported, default to Collada Phong common profile Not supported, default to Collada Phong common profile DU-002761-001_v01 97 April 2008
FX Composer 2.5 Getting Started User’s Guide illum_6 illum_7 illum_8 illum_9 illum_10 Not supported, default to Collada Phong common profile Not supported, default to Collada Phong common profile Not supported, default to Collada Phong common profile Collada Phong common profile Not supported, default to Collada Phong common profile Colors and Float Modifiers Note: For all colors the use of CIEXYZ and Spectral files are not supported e.g., Ka spectral file.rfl factor Ka xyz x y z Ambient Color (Ka r g b) The Ka statement specifies the ambient reflectivity using RGB values. "r g b" are the values for the red, green, and blue components of the color. The g and b arguments are optional. If only r is specified, then g, and b are assumed to be equal to r. The r g b values are normally in the range of 0.0 to 1.0. Values outside this range increase or decrease the reflectivity accordingly. Importing to FX Composer is trivial; this simply becomes the ambient color of the material. Diffuse Color (Kd r g b) The Kd statement specifies the diffuse reflectivity using RGB values. "r g b" are the values for the red, green, and blue components of the atmosphere. The g and b arguments are optional. If only r is specified, then g, and b are assumed to be equal to r. The r g b values are normally in the range of 0.0 to 1.0. Values outside this range increase or decrease the reflectivity accordingly. Importing to FX Composer is trivial; this simply becomes the diffuse color of the material. Specular Color (Ks r g b) The Ks statement specifies the specular reflectivity using RGB values. "r g b" are the values for the red, green, and blue components of the atmosphere. The g and b arguments are optional. If only r is specified, then g, and b are assumed to be equal to r.
