The alpha channel determines how strong the effect of the reflection orrefraction will be, and they are both over-riding effects, reflection being themost over-riding of the two. <span style='mso-spacerun:yes'> </span>So ifrefraction’s alpha channel is 1.0, the object’s color and texture will becompletely gone, the object will only have the refracted texture on it. If thealpha channel is 0.5, then it will be half refracted texture, halfcolor/diffuse texture. The same works with reflection except that reflectionwill over-ride refraction, so if an object is 100% refractive and 100%reflective, you will only see the reflection. Where as if the reflection is 50%and refraction is 50%, the distribution of the texture will be 50% reflective,25% refractive, 25% diffuse. The refractive power float array dictates how muchthe light bends, so if it is equal to 1.0, the light will not bend at all,where as if it is set to 0.9, it will bend about 10% of the angle of the normalof the fragment.</p><p class=MsoListParagraphCxSpLast style='margin-left:54.0pt;mso-add-space:auto;text-indent:-18.0pt;mso-list:l3 level1 lfo5'><![if !supportLists]><spanstyle='mso-bidi-font-family:Calibri;mso-bidi-theme-font:minor-latin'><spanstyle='mso-list:Ignore'>3)<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]>Set the material onto the object<spanclass=GramE>:</span><br><i style='mso-bidi-font-style:normal'>object-><span class=SpellE>setMaterial</span>(mat);</i><br>NOTE: this will convert the object to a material object and attach thematerial.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>A quick example of how to make a glass like cube would be:</p><p class=MsoNormal><br><span class=SpellE><i style='mso-bidi-font-style:normal'>iObject</i></span><istyle='mso-bidi-font-style:normal'>* boxy = <span class=SpellE>CreateBox</span>(-10.0f, 0.25),-10,-10, 10, 10, 10, “opaque”&power, &Colour(1.0f, 1.0f, 1.0f,1.0f));<br><span class=SpellE>iMaterial</span>* mat = <span class=SpellE>CreateMaterial</span\\ boxy->setMaterial(context);<br>float power = 0.9f; //this is just to sidestep the need for an array<br>mat->setup(&Colour(0.7f, 0.7f, 0.7f, 0.7f), NULL, &Colour(1.0f,_1.0f, 1.0f, 0.25), &power, &Colour(1.0f, 1.0f, 1.0f, 1.0f));<br>boxy-><span class=SpellE>setMaterial</span>(mat);<o:p></o:p></i></p><p class=MsoNormal>I didn’t test the above code so there could be a typo.</p></div></body></html>
