Canvas3DItem

Extension

Create a new item.

Returns:

Create a 2x2x2 cube centered around [0,0,0]. You can then use -transform to change it's size, position and rotation.

Returns:

Create a flat NxN grid centered around [0,0,0], spanning [-1,-1,0] to [1,1,0].

Returns:

Create a prism.

Returns:

Get/set the array of paths, where each path is an array of 3D vectors: [x,y,z]

Discussion:

For example, two lines:#[ [ [-1,-1,-1], [ 1, 1, 1] ], [ [ 1,-1,-1], [-1,-1, 1] ] ]

Get/set the item Color

Get/set the item line-width.

Get/set the Boolean flag for stroking versus filling the item's path. See Pen: *stroke and Pen: *fill.

An array of transformation matrices to be applied when displayed in the canvas.

See Canvas3D: matrix_transforms.

Discussion:

These transforms are applied dynamically in the canvas each time it's refreshed. They don't alter the items paths in place.

Example:item.transforms = [ Canvas3D.mRotateY(0.5), Canvas3D.mScale(2,3,1.5), Canvas3D.mTranslate(0,2,1), ];

Apply a transformation matrix on this items paths.

Arguments:

Discussion:

This transform is applied on the actual paths, and is a static one-time operation.

Example:item.transform(Canvas3D.mRotateY(0.5)); item.transform(Canvas3D.mScale(2,3,1.5)); item.transform(Canvas3D.mTranslate(0,2,1));
