9.22 Material

This effect should be used along with the Light effect. After you have set you light properties, you are expected to set your "Material" properties as well. As with a light source. A material has a Specular, Emissive (ambient) and Diffuse property.

Please refer to the Light effect or the Blue Book Chapter 5 for more information.

MatShininess

10

[0.0,128.0]

ComputeSurface

1

{0,1}

Set to 1 if you want to break down the surface into a quad grid so that lighting effects are smoother. If another effect down the effect stack is doing this for you, then you can set this to 0.

Input pattern: (A)

Image-Op: If ComputeSurface is set to 1

9.22.1 Examples

9.22.1.1 Simple material example

; muSE v2
; My yellowish style

(style-parameters)

(segment-durations 8.0)

(define muvee-global-effect (effect-stack
                                (effect "Perspective" (A))
                                (effect "CropMedia" (A))))

(define muvee-segment-effect (effect-stack
                              (effect "Light" (A))
                              (effect "Material" (A)
                                      (param "MatColorB" 0.0))))

In this simple example, the material will not absorb any blue color. What that implies is that we end up with a yellow-ish looking muvee.

9.22.1.2 Searchlight style with only diffuse color.

; muSE v2
; Searchlight2. The return!

(style-parameters)

(segment-durations 8.0)

(define muvee-global-effect (effect-stack
                                (effect "Perspective" (A))
                                (effect "CropMedia" (A))))

(define muvee-segment-effect (effect-stack
                              (effect "Light" (A)
                                      (param "LightDiffuseR" 1.0)
                                      (param "LightDiffuseG" 1.0)
                                      (param "LightDiffuseB" 1.0)
                                      (param "DefaultMaterialColor" 0))
                              (effect "Material" (A)
                                      (param "MatColorR" 0.0)
                                      (param "MatColorG" 0.0)
                                      (param "MatColorB" 0.0))))

The above example is *almost* the same as the one we showed in the Light effect. Except that this time, the material only absorbs Diffuse light as its emissive and color are set to zero. As can be seen, we have a really circular search light.
