TG Glow Shaders

PARAMETERS

TG Glow Colour Ramp

Min Colour

Range : Colour values

The colour represented by black in the Ramp image.

Max Colour

Range : Colour values

The colour represented by white in the Ramp image.

Use True Angle

Range : Unchecked / Checked

When unchecked, the shader works with the angle between the direction of view and the surface normal as in previous incarnations of the TG Glow shader. This actually uses the Cosine of the angle between the two vectors, so introduces a non-linear sweep to the values (so what you see in the Ramp isn’t exactly what you get in the render).

When checked, the shader does the extra bit of processing (so may be a little slower) in order to work back to the linear sweep of the angle between the two vectors, so moves through the Ramp values in a linear fashion.

Angle Ramp

Range : Image

Used to control the transition points between the colours dependent on angle of view.

Black represents the “Min Colour”, white represents the “Max Colour”, the left edge of the Ramp is the outermost edge of a sphere (that is, surfaces pointing almost at right angles to the direction of view), while the right edge of the Ramp is the innermost surfaces on a sphere (that is, surfaces pointing straight back at the direction of view).

TG Glow Colour RampGradient

Use True Angle : See previous

Angle Ramp : See previous

Angle Gradient

Range : Image

Used to control the colours dependent on the values in the Ramp image.

The leftmost edge of the Gradient image is read for black in the Ramp image, and the rightmost edge of the Gradient image is read for white in the Ramp image. Greyscale values between white and black read from proportionally along the Gradient from left to right.

TG Glow Transparency Ramp

Minimum Opacity

Range : -5 to 1

The opacity represented by black in the Ramp image. Negative values are permitted for unusual effects (see the Tips page, which duplicates the documentation from the free shader, TG GlowT).

Maximum Opacity

Range : -5 to 1

The opacity represented by white in the Ramp image. Negative values are permitted for unusual effects (see the Tips page, which duplicates the documentation from the free shader, TG GlowT).

Coloured Transparency

Range : Unchecked / Checked

Adds in coloured transparency effects. These affect the colour of the shadows, as well as the colour of the transparent object. Enabling this generally gives a much brighter appearance to the object.

Transparent Colour

Range : Colour Values

The colour to use in the coloured transparency effects (only has an effect if Coloured Transparency is checked).

Use True Angle : See previous

Angle Ramp : See previous
