Namespace c3dl.effects

The cartoon effect renders objects as if they were cartoons. This effect only uses some light information.For positional lights, the position is taken into account. For directional lights, the direction is taken into account and for spotlights, the position, direction and cutoff are taken into account.

Parameters
qMap {String} Path of a quantization map.

Gooch shading is a type of Non-photorealistic rendering (NPR) which is often used in technical illustrations since it properly conveys the shape of objects. Warm and cool colors are used to indicate the surface normals and therefore the curvature of the object.

Parameters
warmColor {Array} [0.5, 0.5, 0.0] Fragments closer to active light are colored using the warm color.
coolColor {Array} [0.0, 0.0, 1.0] Fragments farther from the active light are colored using the cool color.
surfaceColor {Array} [0.1, 0.1, 0.1] Base surface color.

The greyscale effect renders objects using shades of grey. The method which is used to convert the colors to greyscale closely matches the NTSC standard to convert colors to greyscale. NTC uses (Red * 0.33 + Green * 0.5 + Blue * 0.17).

Parameters
color {Array} [0.3, 0.6, 0.1] Values closely match the NTSC standard values to convert color to greyscale values.

Renders objects using sepia color tones. Once the final colors are calculated for each fragment, they will be converted to greyscale, and finally multiplied by the sepia tone.

Parameters
color {Array} [1.2, 1.0, 0.8] Sepia tone.

This constant is an effect and therefore does not need to be instantiated. If a geometric object is not explicitly assigned an effect, it will be rendered using this instance effect which is closely matches the fixed function pipepline shaders. Use this if an object was assigned an effect, but should then be set back to standard rendering.

This can be passed directly to an object's setEffect.

Parameters
none
