Basic creation and control of surfaces/textures |
The number of shaders that a model is the same as the number of meshes in the model. Each mesh therefore only supports ONE shader. The best example of this is a box (if you cannot see a "water" type texture on the box below, right click over it and select "Restart" - this is a problem caused if the movie starts while the texture is still loading - more advanced "loading" Lingo scripts can deal with this):
By default a box/cube has 6 meshes – one for each side. Each of these meshes has a shader, which means that each side of the box can be treated as a different material (e.g. a side made from metal, a side made from wood, a side made from glass, etc). First you need to either create a new texture object or make a reference to an existing texture object. The Lingo syntax for creating a new texture object is as follows:
Here is the custom handler routine we use in the example above - called "Texturize":
This "texturize" custom handler provides a concise method of creating a new texture, shader and applies these to a given model in a given scene. To set up a shader called "water", we call a texture image from the (image) castmember - water, and apply it to the cube: texturize("test", "cube",
"water", "watershader", rgb(50,25,4), rgb(150,50,10),
rgb(255,255,255)) |
