BoxGenerator

class cee.utils.BoxGenerator()

Helper class to tesselate a box with 6 faces

Useful when result values need to be mapped onto a set of 3D points defining a box. See the method createCuttingSolid in the example in Examples/DemoAppUg on how to do that.

Methods

fillVerticesIndices

BoxGenerator.fillVerticesIndices(vertices, indices)

Arguments:

• vertices (Float32Array) – The vertices in the format x,y,z,x,y,z,…
• indices ([number]) – The indices for the vertices

Fills the members m_vertices and m_indices of this class.

Return type:void

generate

BoxGenerator.generate()

Generate the box

Return type:void

getIndices

BoxGenerator.getIndices()

Get the indices of triangles needed to render the solid object

Return type:[number]

getVertices

BoxGenerator.getVertices()

Get the vertices of the solid object as Vec3

Return type:[Vec3]

getVerticesNumber

BoxGenerator.getVerticesNumber()

Get the vertices of the solid object as a number array with <x,y,z,x,y,z,…>

Return type:[number]

setCenterAndExtent

BoxGenerator.setCenterAndExtent(center, extent)

Arguments:

• center (Vec3) – None
• extent (Vec3) – None

Specify the box by providing the center of the box and the extent in x,y, and z direction.

Return type:void

setNumSegments

BoxGenerator.setNumSegments(numX, numY, numZ)

Arguments:

• numX (number) – None
• numY (number) – None
• numZ (number) – None

Sets the number of segments of the box per axis.

Return type:void

setOrientation

BoxGenerator.setOrientation(rightDir, upDir)

Arguments:

• rightDir (Vec3) – None
• upDir (Vec3) – None

Set the orientation of the box by giing the right direction (local x axis) and the up direction (local z axis).

Return type:void

setOriginAndExtent

BoxGenerator.setOriginAndExtent(origin, extent)

Arguments:

• origin (Vec3) – None
• extent (Vec3) – None

Specify the box by providing an origin (min x,y,z of the box) and the extent in x,y and z direction.

Return type:void
