Description
DimPlaneMixin is a mixin containing rules that can be used by other designs—but see Note, below.
We do not use it alone; instead, it is used to add the rules to other designs. NOTE: presently there are no UI designs that use this mixin (see below).
Although this mixin is not mixed into LinearDimension, LinearDimension has these same rules and formulas.
Parameter Rules
| dimPlane3DFromPoint: |
| Formula: | if (this.viewport === null) { |
| return this.fromPoint |
| } else { |
| return this.projectPoint(this.fromPoint, this.dimPlaneModelPoint, this.dimPlaneModelNormal) |
| }; |
| dimPlane3DToPoint: |
| Formula: | if (this.viewport === null) { |
| return this.toPoint |
| } else { |
| return this.projectPoint(this.toPoint, this.dimPlaneModelPoint, this.dimPlaneModelNormal) |
| }; |
dimPlaneModelMeasurement-
| Direction: |
| Formula: | return this.dimPlane3DToPoint.sub(this.dimPlane3DFromPoint).unitize(); |
| dimPlaneModelNormal: |
| Formula: | const cam = this.viewport.camera; |
| return cam.eye.sub(cam.target).unitize(); |
| dimPlaneModelPoint: |
| Formula: | this.viewport.camera.target; |
| projectedFromPoint: |
| Formula: | if (this.viewport === null) { |
| return this.dimPlane3DFromPoint; |
| } else { |
| return this.viewport.worldToPaper(this.dimPlane3DFromPoint); |
| }; |
| projectedToPoint: |
| Formula: | if (this.viewport === null) { |
| return this.dimPlane3DToPoint; |
| } else { |
| return this.viewport.worldToPaper(this.dimPlane3DToPoint); |
| }; |
