| TG Glow Shaders |
| Test spheres using TG Glow Colour and Transparency Ramp. |
| What They Do The TG Glow shaders have always been some of my favourites. There are colour and transparency versions of the shaders, and now Ramp and Gradient processing has been introduced to make them even more flexible. They’re designed to do much the same thing as the existing free TG Glow C and TG Glow T shaders, only now there’s a whole new range of control over the effects, as you aren’t just limited to a certain number of colours or transition points. Use them for glows around bulbs, planetary atmospheres, etc! The shader names below will take you to their parameters section if you click on them. |
| The Shaders |
| TG Glow Colour Ramp Features the same colour controls as the free TG GlowC, but the blend between the two colours based on angle is controlled by a Ramp (so you can fade from one colour to the other in any way you choose, rather than just at preset transition points). |
| TG Glow Colour RampGradient Here the angle controls are replaced by a Ramp as in TG Glow Colour Ramp, but in this shader the colours are replaced by a Gradient too. No numeric options (except one checkbox!) in the shader, because none are required! |
| TG Glow Transparency Ramp The transparency equivalent of TG Glow Colour Ramp (or, if you prefer, the Ramp driven equivalent of the free TG GlowT). |
| Quick Features and Suggested Uses 1. Create glows around bulbs, stars, comets, etc. 2. Create planetary atmospheres when rendering “space-scapes”. 3. Create ghost-like renderings, eg for text, or for.. well, a ghost maybe! 4. Use both the Colour and Transparency versions together, to control how an object varies in colour as well as opacity (eg, when creating a planetary atmosphere). The identical processing that lies beneath each shader means you can match both channels to work together in any way you wish. 5. Use the Colour versions as layered shaders, to add some multi-coloured effects to an object’s surface in the diffuse channel (perhaps for an oiled metal type look), or for materials which alter colour based on angle of view (some fabrics do this, for example, as do some car paints). |
