Description
An abstract class for 3D shape classes.
Instance Methods
.points
An array of RedVector3D defining the corners of the shape.
.outlines
An array of arrays with pairs of indices defining connections between the points (corners) of the shape.
.surfaces
An array or arrays with four indices defining the planes (rectangles) of the shape.
.position
Get or set the current position of the shape as a RedVector3D.
.rotation
.rotationX
Set the angle of rotation around the X axis.
Arguments:
| theta |
In radians. |
.rotationY
Set the angle of rotation around the Y axis.
Arguments:
| theta |
In radians. |
.rotationZ
Set the angle of rotation around the Z axis.
Arguments:
| theta |
In radians. |
.rotationMatrices
Returns an array of 3 arrays each holding a 3-row matrix for the current rotation in X, Y and Z dimensions. This is calculated when calling -update.
.vectors
An array of RedVector3D. This holds the current positions of all points (corners) after rotation. This is calculated when calling -update.
.renderedPoints
An array of Points. This holds the current positions of all points (corners) after projection and scaling. This is calculated when calling -render.
Arguments:
| dist |
Distance. A value lower than 2 exaggerate the depth. |
| size |
Scaling factor. |
.update
Call this to perform the rotation calculations. This updates the variable -vectors.
.render
Call this to perform the projection and scaling calculations. This updates the variable -rederedPoints.
.draw
Draws an oval at each point (in each corner). Must be called inside a draw function. Use Pen.fillColor_ to set the color.
Arguments:
| dotSize |
The size of the oval. |
.drawOutlines
Draws a line between each point (all edges). Must be called inside a draw function. Use Pen.strokeColor_ to set the color, and Pen.width_ to set the line thickness.
.drawSurfaces
Draws a rectangle for each plane. Must be called inside a draw function. Use Pen.fillColor_ to set the color.
