Materials for model elements

All of the materials used in modeling are defined in the Materials list. All virtual model elements use these materials. Material defines the looks of the model element. Materials must be first defined before it can be used in 3D objects. Materials use texture files. MAGNET Modeler reads texture files from texture folders. Please see article “Texture and Sound libraries” for more information.

Materials can be edited through the material selection dialog which appears every time you choose material for any object. With left click you can choose and with right click you can access menu where you can delete, modify or add new materials.

When choosing the texture for a material or selecting a material with texture to object definition, you can see preview of a texture in the dialog. This helps selecting the right texture/material.

AutoCAD colors are used as material for objects which don't have any material assigned.

Parameters

name  - Name of the material. This is shown when you select materials for 3D objects.

filename  - Name of the texture file. If left empty only color of the material is shown.

description  - A descriptive text for the entry. If defined, will be shown instead of the long description.

ambient  - Surface color where no direct sunlight is hit, called also as shadow side color. Generally same as diffuse.

emission  - Color that is multiplied with other colors. Generally 0,0,0 but can be used to make a fluorescent effect.

diffuse  - Surface color where direct sunlight hits. This is the most dominant color.

specular  - Defines the intensity and color of specular highlight effect. If the material does not shine (most cases) let this to be zero(black).

shininess  - Shininess (scope of the highlight) of the material, 0-1.

transparency  - Transparency of the material, 0-1

defaultwidth  - Width of the texture in drawing units. Other uses for elements and building wall textures, see object properties for details.

defaultheight  - Height of the texture in drawing units. Other uses for elements and building wall textures, see object properties for details.

reflective   

  • yes - Material reflects its surroundings.
  • no - Material does not reflect its surroundings.

physics_friction  - The friction coefficient that is used in the 'simulate car physics' mode for the surface ma-terial friction calculation. Range 0..1, where 0 equals to ‘no friction’ and 1 equals to ‘full friction’.
