Global Parameters

These windows collect all the global settings such as background and lighting.

Lighting

Jot supports up to four positional/directional light sources and one global ambient light source. Lighting can have an effect on the normal and toon shaders described in the basecoat section.

Global lighting parameters.

0, 1, 2, 3

Select one of the four positional/directional lights to edit. When a light is selected the other controls will change to reflect the chosen light settings.

G

Select global ambient light.

On

Light is active when checked.

Dir

Light is directional when checked, positional when not checked.

Cam

Light position/direction is defined in terms of camera frame when checked, world frame when not checked.

Dif/Amb

Select the editing of diffuse/ambient color of light.

Pos/Dir

Adjust position/direction of the light.

Radius

Adjust the radius from world/cam origin associated with positional light.

Hue, Saturation, Value

Adjust color of the chosen light.

Background

The background is rendered as a solid colored quad with optional texture mapping and paper shader.

Paper

A paper effect shader can be applied to basecoat shader, strokes, and the background. The paper parameters selected here affect only basecoat and the background.

Antialiasing

Full scene jittered antialiasing is implemented using the accumulation buffer. This incurses a tremendous performance hit, making it useful for batch rendering of animations.
