3D basics
Using a texture to place an image on the surface of a
model
Each shader can have textures applied to it. Textures are 2D images drawn on the surface of a model. The appearance
of the model’s surface is the combined effect of the shader and textures applied to it. If you do not specify a texture, a
default red-and-white bitmap is used.
To see how to create a new texture object and apply it to a shader, download the movie Texture.dir and launch it.
You can create a texture from an image object or a member with a .image property
This example creates a new texture in the cast member “3D World” to display the image of the bitmap member “Felt
256x256”:
v3Dworld = member("3D World")
vName = "Felt Texture"
vBitmap = member("Felt 256x256")
vTexture = v3Dworld.newTexture(vName, #fromCastMember, vBitmap)
Alternatively, you can create a texture without associating an image to it. You can set the image or member of a texture
at any time:
vTexture = v3Dworld.newTexture(vName)
vTexture.member = vBitmap
Displaying a texture
Textures can be displayed in three different ways:
As a 2D image projected by the camera, as an overlay or a backdrop
One each of the particles emitted by a particle system
As part of a shader object that is attached to a model
For more information on overlays and backdrops, see “Overlays and backdrops” on page 47.
For more information on particle systems, see “Particle emitters” on page 74.
A shader contains 8 layers; a texture can be applied to each of the layers. You can adjust the settings of the different
layers to create different effects, such as surface texture, reaction to diffuse light, reflections that appear to come from
the environment, variations in the shininess of the surface and highlights. For details on how textures interact with the
various shader layers, see “Standard shaders” on page 131.
